127-506: In psychology, temperament broadly refers to consistent individual differences in behavior that are biologically based and are relatively independent of learning, system of values and attitudes. Some researchers point to association of temperament with formal dynamical features of behavior, such as energetic aspects, plasticity, sensitivity to specific reinforcers and emotionality. Temperament traits (such as neuroticism, sociability, impulsivity, etc.) are distinct patterns in behavior throughout
254-442: A behavioral problem may actually be a mismatch between the parent's temperament and their child's. By taking a closer look at the nine traits that Thomas and Chess revealed from their study, parents can gain a better understanding of their child's temperament and their own. Parents may also notice that situational factors cause a child's temperament to seem problematic; for example, a child with low rhythmicity can cause difficulties for
381-510: A biological basis of personality have examined the relationship between temperament and neurotransmitter systems and character (defined in this context as developmental aspects of personality). Temperament is hypothesized to be associated with biological factors, but these have proven to be complex and diverse, and biological correlations have proven hard to confirm. Several psychiatrists and differential psychologists have suggested that temperament and mental illness represent varying degrees along
508-465: A child fits in at school, with their friends, and at home. Behaviors for each one of these traits are on a continuum . If a child leans towards the high or low end of the scale, it could be a cause for concern. The specific behaviors are: activity level, regularity of sleeping and eating patterns, initial reaction, adaptability, intensity of emotion , mood , distractibility, persistence and attention span , and sensory sensitivity. Redundancies between
635-507: A child's reaction. It is also important to know that temperament does not excuse a child's unacceptable behavior, but it does provide direction to how parents can respond to it. Making small and reasonable accommodations to routines can reduce tension. For example, a child who is slow-paced in the mornings may need an extra half-hour to get ready. Knowing who or what may affect the child's behavior can help to alleviate potential problems. Although children obtain their temperament behaviors innately,
762-441: A child's temperament can help reframe how parents interpret children's behavior and the way parents think about the reasons for behaviors. By parents having access to this knowledge now helps them to guide their child in ways that respect the child's individual differences. By understanding children's temperaments and our own helps adults to work with them rather than try to change them. It is an opportunity to anticipate and understand
889-593: A desire for sensation seeking. This factor reflects the degree to which a child is generally happy, active, and enjoys vocalizing and seeking stimulation. Increased levels of smiling and laughter are observed in babies high in surgency/extraversion. 10- to 11-year-olds with higher levels of surgency/extraversion are more likely to develop externalizing problems like acting out; however, they are less likely to develop internalizing problems such as shyness and low self-esteem . Negative affect includes fear , frustration , sadness , discomfort, and anger . This factor reflects
1016-530: A difficult time adjusting. The interactions between these children and their parents or siblings are among a number of factors that can lead to stress and friction within the family. The temperament mix between parents and children also affects family life. For example, a slow-paced parent may be irritated by a highly active child; or if both parent and child are highly active and intense, conflict could result. This knowledge can help parents figure out how temperaments affect family relationships. What may appear to be
1143-521: A dour mood and anxiety over the future, [and] to be more religious." Alexander Thomas, Stella Chess , Herbert G. Birch, Margaret Hertzig and Sam Korn began the classic New York Longitudinal study in the early 1950s regarding infant temperament (Thomas, Chess & Birch, 1968). The study focused on how temperamental qualities influence adjustment throughout life. Chess, Thomas et al. rated young infants on nine temperament characteristics, each of which, by itself, or with connection to another, affects how well
1270-444: A dream in which the god Asclepius appeared and commanded Nicon to send his son to study medicine. Following his earlier liberal education, Galen at age 16 began his studies at the prestigious local healing temple or asclepeion as a θεραπευτής ( therapeutes , or attendant) for four years. There he came under the influence of men like Aeschrion of Pergamon , Stratonicus and Satyrus. Asclepiea functioned as spas or sanitoria to which
1397-630: A family with a highly scheduled life, and a child with a high activity level may be difficult to cope with if the family lives in a crowded apartment upstairs from sensitive neighbors. Parents can encourage new behaviors in their children, and with enough support a slow-to-warm-up child can become less shy, or a difficult baby can become easier to handle. More recently infants and children with temperament issues have been called "spirited" to avoid negative connotations of " difficult " and " slow to warm up ". Numerous books have been written advising parents how to raise their spirited youngsters. Understanding

When a parent takes the time to identify and more importantly respond to the temperaments they are faced with in a positive way it will help them guide their child in trying to figure out the world. Recognizing the child's temperament and helping them to understand how it impacts his/her life as well as others
1651-404: A lifetime, but they are most noticeable and most studied in children. Babies are typically described by temperament, but longitudinal research in the 1920s began to establish temperament as something which is stable across the lifespan. Temperament has been defined as "the constellation of inborn traits that determine a child's unique behavioral style and the way he or she experiences and reacts to
1778-606: A lot. They also tend to have irregular eating and sleeping patterns. Slow-to-warm-up babies have a low activity level, and tend to withdraw from new situations and people. They are slow to adapt to new experiences, but accept them after repeated exposure. Thomas, Chess, Birch, Hertzig and Korn found that these broad patterns of temperamental qualities are remarkably stable through childhood. These traits are also found in children across all cultures. Thomas and Chess also studied temperament and environment. One sample consisted of white middle-class families with high educational status and
1905-404: A male, preferably of an older, wiser, age, as well as free from the control of the passions. These passions, according to Galen, caused the psychological problems that people experienced. Galen may have produced more work than any author in antiquity, rivaling the quantity of work issued from Augustine of Hippo . So profuse was Galen's output that the surviving texts represent nearly half of all
2032-738: A materialist reading of Galen's philosophy of mind. According to this materialist reading, Galen identifies the soul with the mixtures of the body. Another one of Galen's major works, On the Diagnosis and Cure of the Soul's Passion , discussed how to approach and treat psychological problems. This was Galen's early attempt at what would later be called psychotherapy . His book contained directions on how to provide counsel to those with psychological issues to prompt them to reveal their deepest passions and secrets, and eventually cure them of their mental deficiency. The leading individual, or therapist, had to be
2159-745: A medical text both in the Latin Middle Ages and Medieval Islam . The 11th-century Suda lexicon states that Galen died at the age of 70, which would place his death in about the year 199. However, there is a reference in Galen's treatise "On Theriac to Piso" (which may, however, be spurious) to events of 204. There are also statements in Arabic sources that he died in Sicily at age 87, after 17 years studying medicine and 70 practicing it, which would mean he died about 216. According to these sources,
2286-752: A modest proportion of children maintained their expected profile due to mediating factors such as intervening family experiences. Those who remained highly inhibited or uninhibited after age 4.5 were at higher risk for developing anxiety and conduct disorders, respectively. Kagan also used two additional classifications, one for infants who were inactive but cried frequently (distressed) and one for those who showed vigorous activity but little crying (aroused). Followed to age 14–17 years, these groups of children showed differing outcomes, including some differences in central nervous system activity. Teenagers who had been classed as high reactives when they were babies were more likely to be "subdued in unfamiliar situations, to report
2413-422: A more complete understanding of the circulatory system, nervous system , respiratory system , and other structures, his work contained scientific errors. Galen believed the circulatory system to consist of two separate one-way systems of distribution, rather than a single unified system of circulation. He believed venous blood to be generated in the liver, from where it was distributed and consumed by all organs of
2540-555: A number of works attributed to Galen. As a consequence, research on Galen's work is fraught with hazard. Various attempts have been made to classify Galen's vast output. For instance Coxe (1846) lists a Prolegomena, or introductory books, followed by 7 classes of treatise embracing Physiology (28 vols.), Hygiene (12), Aetiology (19), Semeiotics (14), Pharmacy (10), Blood letting (4), and Therapeutics (17), in addition to 4 of aphorisms, and spurious works. The most complete compendium of Galen's writings, surpassing even modern projects like
2667-521: A pestilence occurred which at its height killed 2,000 people a day in Rome. This was most likely the same plague (the so-called "Antonine Plague" and most likely smallpox) that struck Rome during Marcus Aurelius' reign. Galen was also physician to Septimius Severus during his reign in Rome. He complimented Severus and Caracalla on keeping a supply of drugs for their friends and mentioned three cases in which they had been of use in 198. The Antonine Plague

#17327659921152794-502: A physician and a philosopher, as he wrote in his treatise titled That the Best Physician Is Also a Philosopher . Galen was very interested in the debate between the rationalist and empiricist medical sects, and his use of direct observation, dissection, and vivisection represents a complex middle ground between the extremes of those two viewpoints. Many of his works have been preserved and/or translated from
2921-459: A physician and philosopher. Born in the ancient city of Pergamon (present-day Bergama , Turkey), Galen traveled extensively, exposing himself to a wide variety of medical theories and discoveries before settling in Rome , where he served prominent members of Roman society and eventually was given the position of personal physician to several emperors . Galen's understanding of anatomy and medicine
3048-472: A pig, and while it was squealing he would tie off the recurrent laryngeal nerve, or vocal cords, showing they controlled the making of sound. He used the same method to tie off the ureters to prove his theories of kidney and bladder function. Galen believed the human body had three interconnected systems that allowed it to work. The first system that he theorized consisted of the brain and the nerves, responsible for thought and sensation. The second theorized system
3175-468: A practicing physician. His public demonstrations and impatience with alternative views on medicine brought him into conflict with other doctors practicing in the city. When the Peripatetic philosopher Eudemus became ill with quartan fever , Galen felt obliged to treat him "since he was my teacher and I happened to live nearby". He wrote: "I return to the case of Eudemus. He was thoroughly attacked by
3302-523: A young man had come to the city and had given, like me practical demonstrations of the resources of our art; this young man was put to death by poison, together with two servants who accompanied him." When Galen's animosity with the Roman medical practitioners became serious, he feared he might be exiled or poisoned, so he left the city. Rome was engaged in foreign wars in 161; Marcus Aurelius and his then co-Emperor and adoptive brother Lucius Verus were in

The vital spirit within this medium was necessary for the body to function and eventually completely absorbed. This process was then repeated indefinitely, according to Galen, so that the body could be replenished with the soul, or the vital spirit. Several schools of thought existed within

At the present time the model is associated with the Structure of Temperament Questionnaire and has 12 scales: Jerome Kagan and his colleagues have concentrated empirical research on a temperamental category termed "reactivity." Four-month-old infants who became "motorically aroused and distressed" to presentations of novel stimuli were termed highly reactive . Those who remained "motorically relaxed and did not cry or fret to
3683-646: Is dependent on the development of executive attention skills in the early years. In turn, executive attention skills allows greater self-control over reactive tendencies. Effortful control shows stability from infancy into the school years and also predicts conscience . Solomon Diamond described temperaments based upon characteristics found in the animal world: fearfulness, aggressiveness, affiliativeness, and impulsiveness. His work has been carried forward by Arnold Buss and Robert Plomin , who developed two measures of temperament: The Colorado Child Temperament Inventory, which includes aspects of Thomas and Chess's schema, and

Galen Aelius Galenus or Claudius Galenus ( Greek : Κλαύδιος Γαληνός ; September 129 – c. 216 AD), often anglicized as Galen ( / ˈ ɡ eɪ l ən / ) or Galen of Pergamon , was a Roman and Greek physician , surgeon , and philosopher . Considered to be one of

Recognizing each individual's temperament, will help to prevent and manage problems that may arise from the differences among family members. Temperament continues into adulthood, and later studies by Chess and Thomas have shown that these characteristics continue to influence behavior and adjustment throughout

4064-418: Is incorrect to say that temperament is a weak degree of these disorders. Temperament might be a disposition to develop a mental disorder, but it should not be treated as a guaranteed marker for disorders. Most experts agree that temperament has a genetic and biological basis, although environmental factors and maturation modify the ways a child's personality is expressed. The term "goodness of fit" refers to
4191-517: The Corpus Medicorum Graecorum/Latinorum [ de ] , is the one compiled and translated by Karl Gottlob Kühn of Leipzig between 1821 and 1833. This collection consists of 122 of Galen's treatises, translated from the original Greek into Latin (the text is presented in both languages). Over 20,000 pages in length, it is divided into 22 volumes, with 676 index pages. Many of Galen's works are included in

Another useful modern source is the French Bibliothèque interuniversitaire de médecine Archived 2014-04-21 at the Wayback Machine (BIUM). In his time, Galen's reputation as both physician and philosopher was legendary, the emperor Marcus Aurelius describing him as "Primum sane medicorum esse, philosophorum autem solum" (first among doctors and unique among philosophers Praen 14: 660 ). Other contemporary authors in
4445-718: The EAS Survey for Children . H. Hill Goldsmith and Joseph Campos used emotional characteristics to define temperament, originally analyzing five emotional qualities: motor activity, anger, fearfulness, pleasure/joy, and interest/persistence, but later expanding to include other emotions. They developed several measures of temperament: Lab-TAB and TBAQ. Other temperament systems include those based upon theories of adult temperament (e.g. Gray and Martin's Temperament Assessment Battery for Children), or adult personality (e.g.the Big Five personality traits). Scientists seeking evidence of
4572-587: The Pyrrhonists . Galen was concerned to combine philosophical thought with medical practice, as in his brief work That the Best Physician is also a Philosopher he took aspects from each group and combined them with his original thought. He regarded medicine as an interdisciplinary field that was best practiced by utilizing theory, observation, and experimentation in conjunction. Galen combined his observations of his dissections with Plato's theory about
4699-525: The Renaissance . Some of Galen's treatises have appeared under many different titles over the years. Sources are often in obscure and difficult-to-access journals or repositories. Although written in Greek, by convention the works are referred to by Latin titles, and often by merely abbreviations of those. No single authoritative collection of his work exists, and controversy remains as to the authenticity of
4826-594: The extant literature from ancient Greece. It has been reported that Galen employed twenty scribes to write down his words. Galen may have written as many as 500 treatises, amounting to some 10 million words. Although his surviving works amount to some 3 million words, this is thought to represent less than a third of his complete writings. In 191, or more likely in 192, a fire in the Temple of Peace destroyed many of his works, in particular treatises on philosophy. Because Galen's works were not translated into Latin in

The influence of Galen's writings, including humorism, remains strong in modern Unani medicine , now closely identified with Islamic culture, and widely practiced from India (where it is officially recognized) to Morocco. Maimonides was influenced by Galen, whom he cited most often in his medical works, and whom he considered to be
5080-572: The "medical refrigerators of antiquity". In late antiquity, medical writing veered increasingly in the direction of the theoretical at the expense of the practical, with many authors merely debating Galenism. Magnus of Nisibis was a pure theorist, as were John of Alexandria and Agnellus of Ravenna with their lectures on Galen's De Sectis . So strong was Galenism that other authors such as Hippocrates began to be seen through Galen's eyes, while his opponents became marginalised and other medical sects such as Asclepiadism slowly disappeared. Greek medicine
5207-434: The 13th century. However, Galen's influence was so great that when dissections discovered anomalies compared with Galen's anatomy, the physicians often tried to fit these into the Galenic system. An example of this is Mondino de Liuzzi , who describes rudimentary blood circulation in his writings but still asserts that the left ventricle should contain air. Some cited these changes as proof that human anatomy had changed since

5334-481: The Arabic. In some cases scholars have even attempted to translate from the Latin or Arabic back into Greek where the original is lost. For some of the ancient sources, such as Herophilus , Galen's account of their work is all that survives. Even in his own time, forgeries and unscrupulous editions of his work were a problem, prompting him to write On His Own Books . Forgeries in Latin, Arabic or Greek continued until
5461-584: The Byzantine Empire. All of the extant Greek manuscripts of Galen were copied by Byzantine scholars. In the Abbasid period (after 750) Arab Muslims began to be interested in Greek scientific and medical texts for the first time, and had some of Galen's texts translated into Arabic, often by Syrian Christian scholars (see below). As a result, some texts of Galen exist only in Arabic translation, while others exist only in medieval Latin translations of

The 7th-century poet George of Pisida went so far as to refer to Christ as a second and neglected Galen. Galen continued to exert an important influence over the theory and practice of medicine until the mid-17th century in the Byzantine and Arabic worlds and Europe. A few centuries after Galen, Palladius Iatrosophista stated in his commentary on Hippocrates that Hippocrates sowed and Galen reaped. Galen summarized and synthesized

Galen's works on anatomy and medicine became the mainstay of the medieval physician's university curriculum, alongside Ibn Sina's The Canon of Medicine , which elaborated on Galen's works. Unlike pagan Rome, Christian Europe did not exercise a universal prohibition of the dissection and autopsy of the human body and such examinations were carried out regularly from at least
5842-542: The Rationalist sect and from the Empiricist sect. Galen was well known for his advancements in medicine and the circulatory system, but he was also concerned with philosophy. He developed his own tripartite soul model following the examples of Plato; some scholars refer to him as a Platonist. Galen developed a theory of personality based on his understanding of fluid circulation in humans, and he believed that there
5969-523: The Stoics' lack of scientific justification discredited their claims of the separateness of mind and body, which is why he spoke so strongly against them. There is an intense scholarly debate about soul–body relations in Galen's psychological writings. In his brief treatise Quod animi mores , Galen says both that the soul "follows" the mixtures of the body, and that the soul is a bodily mixture. Scholars have offered ways of reconciling these claims, arguing for

In 157, aged 28, he returned to Pergamon as physician to the gladiators of the High Priest of Asia, one of

His father, Aelius Nicon , was a wealthy patrician , an architect and builder, with eclectic interests including philosophy, mathematics, logic, astronomy, agriculture and literature. Galen describes his father as a "highly amiable, just, good and benevolent man". At that time Pergamon (modern-day Bergama , Turkey) was a major cultural and intellectual centre, noted for its library , second only to that in Alexandria, as well as being

It depended on the severity of the intestinal lesions. He observes that in cases where the stool was not black, the black exanthema appeared. Galen describes the symptoms of fever, vomiting, fetid breath, catarrh , cough, and ulceration of the larynx and trachea. Galen continued to work and write in his final years, finishing treatises on drugs and remedies as well as his compendium of diagnostics and therapeutics, which would have much influence as

However, in general, Galen and the ancient Greek medical tradition continued to be studied and followed in the Eastern Roman Empire , commonly known as

Thus, Galen asserted that there are small holes in the septum dividing the left and right sides of the heart; these holes allowed the blood to pass through easily to receive air and exchange the aforementioned waste products. Although his anatomical experiments on animal models led him to
6731-479: The body and that the soul, as a whole, contributed to the health of the body, strengthening the "natural functioning capacity of the organ or organs in question". The rational soul controlled higher level cognitive functioning in an organism, for example, making choices or perceiving the world and sending those signals to the brain. He also listed "imagination, memory, recollection, knowledge, thought, consideration, voluntary motion, and sensation" as being found within
6858-458: The body to its function indicated the role of an intelligent creator. His creationism was anticipated by the anatomical examples of Socrates and Empedocles . Although the main focus of his work was on medicine, anatomy, and physiology, Galen also wrote about logic and philosophy. His writings were influenced by earlier Greek and Roman thinkers, including Plato , Aristotle , the Stoics , and
6985-503: The body. He posited that arterial blood originated in the heart, from where it was distributed and consumed by all organs of the body. The blood was then regenerated in either the liver or the heart, completing the cycle. Galen also believed in the existence of a group of blood vessels he called the rete mirabile in the carotid sinus. Both of these theories of the circulation of blood were later (beginning with works of Ibn al-Nafis published c. 1242 ) shown to be incorrect. Galen
7112-459: The body. More important is that it includes details of more than 150 single and compound formulations of both herbal and animal origin. The book provides an insight into understanding the traditions and methods of treatment in the Greek and Roman eras. In addition, this book provides a direct source for the study of more than 150 single and compound drugs used during the Greco-Roman period. As
7239-436: The brain. He conducted many anatomical studies on animals, most famously an ox, to study the transition from vital to psychic pneuma . Although highly criticized for comparing animal anatomy to human anatomy, Galen was convinced that his knowledge was abundant enough in both anatomies to base one on the other. In his treatise On the usefulness of the parts of the body , Galen argued that the perfect suitability of each part of

Research by Thomas and Chess used the following nine temperament traits in children based on a classification scheme developed by Dr. Herbert Birch: Thomas, Chess, Birch, Hertzig and Korn found that many babies could be categorized into one of three groups: easy , difficult , and slow-to-warm-up (Thomas & Chess 1977). Not all children can be placed in one of these groups. Approximately 65% of children fit one of
7493-475: The circulatory system. The blood created in the liver would eventually flow unidirectionally into the right ventricle of the heart via the great vein. Galen also proposed a theory on how blood receives air from the lungs to be distributed throughout the body. He declared that the venous artery carried air from the lungs into the left ventricle of the heart to mix with created blood from the liver. This same venous artery allowed for an exchange of waste products from
7620-518: The crystalline lens is located in the anterior aspect of the human eye. At first reluctantly but then with increasing vigor, Galen promoted Hippocratic teaching, including venesection and bloodletting , then unknown in Rome. This was sharply criticized by the Erasistrateans , who predicted dire outcomes, believing that it was not blood but pneuma that flowed in the veins. Galen, however, staunchly defended venesection in his three books on

From that time, Galenism took on a new, unquestioned authority, Galen even being referred to as the "Medical Pope of the Middle Ages".

In addition to the more numerous translations of Arabic texts in this period, there were a few translations of Galenic works directly from

Anger and frustration, together, predict externalizing and internalizing difficulties. Anger, alone, is later related to externalizing problems, while fear is associated with internalizing difficulties. Fear as evidenced by behavioral inhibition is seen as early as 7–10 months of age, and later predicts children's fearfulness and lower levels of aggression . Effortful control includes

Though incorrect in his studies of human reproduction and reproductive anatomy, he came very close to identifying the ovaries as analogous to

Because of this restriction, Galen performed anatomical dissections on living ( vivisection ) and dead animals, mostly focusing on primates . Galen believed that the anatomical structures of these animals closely mirrored those of humans. Galen clarified the anatomy of the trachea and was the first to demonstrate that the larynx generates

Using factor analysis on data from 3- to 12-month-old children, three broad factors emerged and were labeled surgency/extraversion, negative affect, and effortful control. Surgency /extraversion includes positive anticipation, impulsivity , increased levels of activity and

Galen was not trying to present a description of the disease so that it could be recognized in future generations; he was more interested in the treatment and physical effects of the disease. For example, in his writings about a young man afflicted with

In 1966, she became an associate professor of child psychiatry at NYU, and in 1970, she became a full professor there. She continued to teach at NYU into her 90s. Chess was known for conducting the New York Longitudinal Study, which concluded that children's temperaments are determined before they are born, and not by

This factor reflects the degree to which a child can focus attention, is not easily distracted, can restrain a dominant response in order to execute a non-dominant response, and employ planning. When high in effortful control, six- to seven-year-olds tend to be more empathetic and lower in aggressiveness. Higher levels of effortful control at age seven also predict lower externalizing problems at age 11 years. Children high on negative affect show decreased internalizing and externalizing problems when they are also high on effortful control. Rothbart suggests that effortful control
8763-499: The greatest physician of all time. In India many Hindu physicians studied Persian and Urdu languages and learnt Galenic medicine. This trend of studies among Hindu physicians began in the 17th century and lasted until the early 20th century (Speziale 2018). From the 11th century onwards, Latin translations of Islamic medical texts began to appear in the West, alongside the Salerno school of thought, and were soon incorporated into

His anatomical reports remained uncontested until 1543, when printed descriptions and illustrations of human dissections were published in the seminal work De humani corporis fabrica by Andreas Vesalius , where Galen's physiological theory was accommodated to these new observations. Galen's theory of the physiology of the circulatory system remained unchallenged until c. 1242 , when Ibn al-Nafis published his book Sharh tashrih al-qanun li' Ibn Sina ( Commentary on Anatomy in Avicenna's Canon ), in which he reported his discovery of pulmonary circulation . Galen saw himself as both

Neither Galen nor Steiner are generally applied to the contemporary study of temperament in the approaches of modern medicine or contemporary psychology. This model based on the longest tradition of neurophysiological experiments started within the investigations of types and properties of nervous systems by Ivan Pavlov 's school. This experimental tradition started on studies with animals in 1910–20s but expanded its methodology to humans since 1930s and especially since 1960s, including EEG, caffeine tests, evoked potentials, behavioral tasks and other psychophysiological methods. The latest version of this model
9144-755: The life-span. In addition to the initial clinical studies, academic psychologists have developed an interest in the field and researchers such as Bates, Buss & Plomin, Kagan , Rusalov , Cloninger , Trofimova and Rothbart have generated large bodies of research in the areas of personality , neuroscience , and behavioral genetics . Temperament is determined through specific behavioral profiles, usually focusing on those that are both easily measurable and testable early in childhood. Commonly tested factors include traits related to energetic capacities (named as "Activity", "Endurance", "Extraversion"), traits related to emotionality (such as irritability, frequency of smiling), and approach or avoidance of unfamiliar events. There
9271-401: The male testes. Reproduction was a controversial topic in Galen's lifetime, as there was much debate over if the male was solely responsible for the seed, or if the woman was also responsible. Through his vivisection practices, Galen also proved that the voice was controlled by the brain. One of the most famous experiments that he recreated in public was the squealing pig: Galen would cut open
9398-413: The match or mismatch between temperament and other personal characteristics and the specific features of the environment. Differences of temperament or behavior styles between individuals are important in family life. They affect the interactions among family members. While some children can adapt quickly and easily to family routines and get along with siblings, others who are more active or intense may have
9525-697: The medical field during Galen's lifetime, the main two being the Empiricists and Rationalists (also called Dogmatists or Philosophers), with the Methodists being a smaller group. The Empiricists emphasized the importance of physical practice and experimentation or "active learning" in the medical discipline. In direct opposition to the Empiricists were the Rationalists, who valued the study of established teachings in order to create new theories in
9652-663: The medieval and early modern Islamic Middle East. Job of Edessa is said to have translated 36 of Galen's works into Syriac, some of which were later translated into Arabic by Hunain ibn Ishaq . Galen's approach to medicine became and remains influential in the Islamic world. The first major translator of Galen into Arabic was the Arab Christian Hunayn ibn Ishaq . He translated ( c. 830–870 ) 129 works of "Jalinos" into Arabic . Arabic sources, such as Muhammad ibn Zakarīya al-Rāzi (AD 865–925), continue to be
9779-420: The mental and the physical. This was a controversial argument at the time, and Galen agreed with some Greek philosophical schools in believing that the mind and body were not separate faculties. He believed that this could be scientifically shown. This was where his opposition to the Stoics became most prevalent. Galen proposed organs within the body to be responsible for specific functions. According to Galen,
9906-421: The most accomplished of all medical researchers of antiquity , Galen influenced the development of various scientific disciplines, including anatomy , physiology , pathology , pharmacology , and neurology , as well as philosophy and logic . The son of Aelius Nicon , a wealthy Greek architect with scholarly interests, Galen received a comprehensive education that prepared him for a successful career as
10033-495: The most influential and wealthy men in Asia. Galen claims that the High Priest chose him over other physicians after he eviscerated an ape and challenged other physicians to repair the damage. When they refused, Galen performed the surgery himself and in so doing won the favor of the High Priest of Asia. Over his four years there, he learned the importance of diet, fitness, hygiene, and preventive measures, as well as living anatomy, and
10160-483: The name of medical advancements. The Methodists formed somewhat of a middle ground, as they were not as experimental as the Empiricists, nor as theoretical as the Rationalists. The Methodists mainly utilized pure observation, showing greater interest in studying the natural course of ailments than making efforts to find remedies. Galen's education had exposed him to the five major schools of thought (Platonists, Peripatetics, Stoics, Epicureans, Pyrrhonists), with teachers from
10287-407: The nervous system. Galen went on to be the first physician to study what happens when the spinal cord is transected on multiple different levels. He worked with pigs and studied their neuroanatomy by severing different nerves either totally or partially to see how it affected the body. He even dealt with diseases affecting the spinal cord and nerves. In his work De motu musculorum , Galen explained
10414-600: The north fighting the Marcomanni . During the autumn of 169 when Roman troops were returning to Aquileia , a great plague, most likely one of the first appearances of smallpox (then referred to as the Antonine Plague ) in the Mediterranean world, broke out, and the emperor summoned Galen back to Rome. He was ordered to accompany Marcus and Verus to Germany as the court physician. The following spring Marcus
10541-471: The original Greek, although many were destroyed and some credited to him are believed to be spurious. Although there is some debate over the date of his death, he was no younger than seventy when he died. Galen's Greek name Γαληνός ( Galēnós ) comes from the adjective γαληνός ( galēnós ) 'calm'. Galen's Latin name (Aelius or Claudius) implies he had Roman citizenship . Galen describes his early life in On
10668-448: The other was of Puerto Rican working-class families. They found several differences. Among those were: Observed traits: Mary K. Rothbart views temperament as the individual personality differences in infants and young children that are present prior to the development of higher cognitive and social aspects of personality . Rothbart further defines temperament as individual differences in reactivity and self-regulation that manifest in
10795-494: The parenting they receive. This study, which she conducted with her husband, Alexander Thomas, also led to her developing a theory, which postulates that the interaction between a child's temperament and the personality of his or her parents can affect the child's mental health. Also on the basis of this study's results, Chess and Thomas categorized children into three categories based on their innate temperaments: "easy", "difficult", and "slow to warm up". She also conducted studies on
10922-475: The patterns. Of the 65%, 40% fit the easy pattern, 10% fell into the difficult pattern, and 15% were slow to warm up. Each category has its own strength and weakness and one is not superior to another. Thomas, Chess, Birch, Hertzig and Korn showed that easy babies readily adapt to new experiences, generally display positive moods and emotions and also have normal eating and sleeping patterns. Difficult babies tend to be very emotional, irritable and fussy, and cry
11049-490: The plague, he concentrated on the treatment of internal and external ulcerations. According to Niebuhr, "this pestilence must have raged with incredible fury; it carried off innumerable victims. The ancient world never recovered from the blow inflicted upon it by the plague that visited it in the reign of M. Aurelius." The mortality rate of the plague was 7–10 percent; the outbreak in 165–168 would have caused approximately 3.5 to 5 million deaths. Otto Seeck believes that over half
11176-479: The pleasures of the body and was moved by feelings of enjoyment. This third part of the soul is the animalistic, or more natural, side of the soul; it deals with the natural urges of the body and survival instincts. Galen proposed that when the soul is moved by too much enjoyment, it reaches states of "incontinence" and "licentiousness", the inability to willfully cease enjoyment, which was a negative consequence of too much pleasure. In order to unite his theories about
11303-515: The population of the empire perished. J. F. Gilliam believes that the Antonine plague probably caused more deaths than any other epidemic during the empire before the mid-3rd century. Although Galen's description is incomplete, it is sufficient to enable a firm identification of the disease as related to smallpox . Galen notes that the exanthema covered the victim's entire body and was usually black. The exanthem became rough and scabby where there
11430-426: The rational soul. The functions of "growing or being alive" resided in the spirited soul. The spirited soul also contained our passions, such as anger. These passions were considered to be even stronger than regular emotions, and, as a consequence, more dangerous. The third part of the soul, or the appetitive spirit, controlled the living forces in our body, most importantly blood. The appetitive spirit also regulated
11557-418: The relationships between temperament traits (such as impulsivity, sensation seeking, neuroticism, endurance, plasticity, sociability or extraversion) and various neurotransmitter and hormonal systems (i.e., the very same systems implicated in mental disorders). Even though temperament and psychiatric disorders can be presented as, correspondingly, weak and strong imbalances within the same regulatory systems, it
11684-610: The same continuum of neurotransmitter imbalances in neurophysiological systems of behavioral regulation. In fact, the original four types of temperament (choleric, melancholic, phlegmatic and sanguine) suggested by Hippocrates and Galen resemble mild forms of types of psychiatric disorders described in modern classifications. Moreover, Hippocrates-Galen hypothesis of chemical imbalances as factors of consistent individual differences has also been validated by research in neurochemistry and psychopharmacology, though modern studies attribute this to different compounds. Many studies have examined
11811-508: The same set of unfamiliar events" were termed low reactive . These high and low reactive infants were tested again at 14 and 21 months "in a variety of unfamiliar laboratory situations." Highly reactive infants were predominantly characterized by a profile of high fear to unfamiliar events, which Kagan termed inhibited. Contrastingly, low reactive children were minimally fearful to novel situations, and were characterized by an uninhibited profile (Kagan). However, when observed again at age 4.5, only
11938-426: The sick would come to seek the ministrations of the priesthood. Romans frequented the temple at Pergamon in search of medical relief from illness and disease. It was also the haunt of notable people such as the historian Claudius Charax, the orator Aelius Aristides , the sophist Polemo , and the consul Cuspius Rufinus . Galen's father died in 148, leaving Galen independently wealthy at the age of 19. He then followed
12065-489: The site of a large temple to the healing god Asclepius . The city attracted both Stoic and Platonic philosophers, to whom Galen was exposed at age 14. His studies also took in each of the principal philosophical systems of the time, including Aristotelian and Epicurean . His father had planned a traditional career for Galen in philosophy or politics and took care to expose him to literary and philosophical influences. However, Galen states that in around 145 his father had
12192-441: The soul and how it operated within the body, he adapted the theory of the pneuma , which he used to explain how the soul operated within its assigned organs, and how those organs, in turn, interacted together. Galen then distinguished the vital pneuma , in the arterial system, from the psychic pneuma , in the brain and nervous system. Galen placed the vital pneuma in the heart and the psychic pneuma ( spiritus animalis ) within
12319-486: The soul as having one part, which was the rational soul and they claimed it would be found in the heart. Galen, following Plato's idea, came up with two more parts to the soul. Galen also rejected Stoic propositional logic and instead embraced a hypothetical syllogistic which was strongly influenced by the Peripatetics and based on elements of Aristotelian logic. Galen believed there is no sharp distinction between
12446-440: The soul. Plato believed that the body and the soul were separate entities, rivaling the Stoics. Plato proclaimed that the soul is immortal, so it must exist before one is born, beyond the human body. This influenced Galen's thinking that the soul had to be acquired because the soul does not always reside within the human body. Plato's influence in Galen's model showed itself most prominently in what Galen dubbed arterial blood, which
12573-622: The source of discovery of new or relatively inaccessible Galenic writings. One of Hunayn's Arabic translations, Kitab ila Aglooqan fi Shifa al Amrad , which is extant in the Library of Ibn Sina Academy of Medieval Medicine & Sciences , is regarded as a masterpiece of Galen's literary works. A part of the Alexandrian compendium of Galen's work, this 10th-century manuscript comprises two parts that include details regarding various types of fevers (Humyat) and different inflammatory conditions of
12700-485: The study of Galen and other Greek works almost disappeared in the Latin West. In contrast, in the predominantly Greek-speaking eastern half of the Roman empire (Byzantium), many commentators of the subsequent centuries, such as Oribasius , physician to the emperor Julian who compiled a Synopsis in the 4th century, preserved and disseminated Galen's works, making them more accessible. Nutton refers to these authors as
12827-552: The subject and in his demonstrations and public disputations. Galen's work on anatomy remained largely unsurpassed and unchallenged up until the 16th century in Europe. In the middle of the 16th century, the anatomist Andreas Vesalius challenged the anatomical knowledge of Galen by conducting dissections on human cadavers. These investigations allowed Vesalius to refute aspects of Galen's theories regarding anatomy. Galen's interest in human anatomy ran afoul of Roman law that prohibited
12954-479: The three attacks of quartan ague, and the doctors had given him up, as it was now mid-winter." Some Roman physicians criticized Galen for his use of the prognosis in his treatment of Eudemus. This practice conflicted with the then-current standard of care , which relied upon divination and mysticism . Galen retaliated against his detractors by defending his own methods. Garcia-Ballester quotes Galen as saying: "In order to diagnose, one must observe and reason." This
13081-484: The time of Galen. The most important translator of Galen's works into Latin was Niccolò di Deoprepio da Reggio, who spent several years working on Galen. Niccolò worked at the Angevin Court during the reign of king Robert of Naples . Among Niccolò's translations is a piece from a medical treatise by Galen, of which the original text is lost. Stella Chess Stella Chess (March 1, 1914 – March 14, 2007)
13208-559: The title of Doubts on Galen by al-Rāzi implies, as well as the writings of physicians such as Ibn Zuhr and Ibn al-Nafis , the works of Galen were not accepted unquestioningly, but as a challengeable basis for further inquiry . A strong emphasis on experimentation and empiricism led to new results and new observations, which were contrasted and combined with those of Galen by writers such as al-Rāzi, Ali ibn Abbas al-Majusi , Abu al-Qasim al-Zahrawi , Ibn Sina (Avicenna), Ibn Zuhr, and Ibn al-Nafis. For example, Ibn al-Nafis' discovery of
13335-522: The tomb of Galenus in Palermo was still well preserved in the tenth century. Nutton believes that "On Theriac to Piso" is genuine, that the Arabic sources are correct, and that the Suda has erroneously interpreted the 70 years of Galen's career in the Arabic tradition as referring to his whole lifespan. Boudon-Millot more or less concurs and favors a date of 216. Galen contributed a substantial amount to
13462-427: The treatment of fractures and severe trauma, referring to their wounds as "windows into the body". Only five deaths among the gladiators occurred while he held the post, compared to sixty in his predecessor's time, a result that is in general ascribed to the attention he paid to their wounds. At the same time he pursued studies in theoretical medicine and philosophy. Galen went to Rome in 162 and made his mark as
13589-872: The understanding of pathology. Under the Hippocratic bodily humors theory, differences in human moods come as a consequence of imbalances in one of the four bodily fluids : blood, yellow bile, black bile, and phlegm. Galen promoted this theory and the typology of human temperaments . In Galen's view, an imbalance of each humor corresponded with a particular human temperament (blood – sanguine, black bile – melancholic, yellow bile – choleric, and phlegm – phlegmatic). Thus, individuals with sanguine temperaments are extroverted and social; choleric people have energy, passion, and charisma; melancholics are creative, kind, and considerate; and phlegmatic temperaments are characterised by dependability, kindness, and affection. Galen
13716-414: The unity of the two subjects and their views. Using their theories, combined with Aristotle's, Galen developed a tripartite soul consisting of similar aspects. He used the same terms as Plato , referring to the three parts as rational, spiritual, and appetitive. Each corresponded to a localized area of the body. The rational soul was in the brain, the spiritual soul was in the heart, and the appetitive soul
13843-471: The voice. In one experiment, Galen used bellows to inflate the lungs of a dead animal. Galen's research on physiology was largely influenced by previous works of philosophers Plato and Aristotle, as well as from the physician Hippocrates. He was one of the first people to use experiments as a method of research for his medical findings. Doing so allowed him to explore various parts of the body and its functions. Among Galen's major contributions to medicine
13970-473: The work of his predecessors, and it is in Galen's words (Galenism) that Greek medicine was handed down to subsequent generations, such that Galenism became the means by which Greek medicine was known to the world. Often, this was in the form of restating and reinterpreting, such as in Magnus of Nisibis' 4th-century work on urine, which was in turn translated into Arabic. Yet the full importance of his contributions
14097-458: The world." Many classification schemes for temperament have been developed, and there is no consensus. The Latin word temperamentum means 'mixture'. Some commentators see temperament as one factor underlying personality. Historically, in the second century AD, the physician Galen described four classical temperaments (melancholic, phlegmatic, sanguine and choleric), corresponding to the four humors or bodily fluids. This historical concept
14224-546: Was a lawyer and her mother was a schoolteacher. Chess graduated from the Ethical Culture School and Smith College . She then enrolled at New York University (NYU) School of Medicine in 1935, receiving her M.D. from there in 1939. While a student there, she took an elective with Lauretta Bender , which solidified her interest in child psychiatry and development. Chess taught at New York Medical College after she received her M.D., and in 1954, she became
14351-424: Was a physiological basis for mental disorders. Galen connected many of his theories to the pneuma and he opposed the Stoics ' definition of and use of the pneuma . The Stoics, according to Galen, failed to give a credible answer for the localization of functions of the psyche, or the mind. Through his use of medicine, he was convinced that he came up with a better answer, the brain. The Stoics only recognized
14478-404: Was also a pioneer in research about the human spine. His dissections and vivisections of animals led to key observations that helped him accurately describe the human spine, spinal cord , and vertebral column . Galen also played a major role in the discoveries of the central nervous system . He was also able to describe the nerves that emerge from the spine, which is integral to his research about
14605-415: Was also a skilled surgeon, operating on human patients. Many of his procedures and techniques would not be used again for centuries, such as the procedures he performed on brains and eyes. His surgical experiments included ligating the arteries of living animals. Although many 20th-century historians have claimed that Galen believed the lens to be in the exact center of the eye, Galen actually understood that
14732-508: Was an American child psychiatrist who taught at New York University (NYU). With her husband, Alexander Thomas, she undertook research into whether the temperaments of children are innate or are dependent on their nurturing. She also conducted studies on the potential links between rubella during pregnancy and autism in the child. The middle of three children, Chess was born in New York City to Russian immigrant parents. Her father
14859-417: Was explored by philosophers , psychologists , psychiatrists and psycho-physiologists from very early times of psychological science, with theories proposed by Immanuel Kant , Hermann Lotze , Ivan Pavlov , Carl Jung , Gerardus Heymans among others. In more recent history, Rudolf Steiner had emphasized the importance of the four classical temperaments in elementary education, the time when he believed
14986-444: Was his work on the circulatory system . He was the first to recognize that there are distinct differences between venous (dark) and arterial (bright) blood. In addition to these discoveries, Galen postulated much more about the nature of the circulatory system . He believed that blood originated in the liver, which follows the teachings of Hippocrates. The liver converted nutrients gathered from ingested food into blood to be used in
15113-440: Was in the liver. Galen was the first scientist and philosopher to assign specific parts of the soul to locations in the body because of his extensive background in medicine. This idea is now referred to as localization of function. Galen's assignments were revolutionary for the time period, which set the precedent for future localization theories. Galen believed each part of this tripartite soul controlled specific functions within
15240-460: Was named after Marcus Aurelius' family name of Antoninus. It was also known as the Plague of Galen and held an important place in medicinal history because of its association with Galen. He had first-hand knowledge of the disease, and was present in Rome when it first struck in 166, and was also present in the winter of 168–69 during an outbreak among troops stationed at Aquileia. He had experience with
15367-426: Was no ulceration. He states that those who were going to survive developed a black exanthem. According to Galen, it was black because of a remnant of blood putrefied in a fever blister that was pustular. His writings state that raised blisters were present in the Antonine plague, usually in the form of a blistery rash. Galen states that the skin rash was close to the one Thucydides described. Galen describes symptoms of
15494-473: Was not appreciated until long after his death. Galen's rhetoric and prolificity were so powerful as to convey the impression that there was little left to learn. The term Galenism has subsequently taken on both a positive and pejorative meaning as one that transformed medicine in late antiquity yet so dominated subsequent thinking as to stifle further progress. After the collapse of the Western Empire
15621-455: Was part of Greek culture, and Syrian Christians came in contact with it while the Eastern Roman Empire (Byzantium) ruled Syria and western Mesopotamia, regions that were conquered in the 7th century by the Arabs . After 750, these Syrian Christians made the first translations of Galen into Syriac and Arabic . From then on, Galen and the Greek medical tradition in general became assimilated into
15748-524: Was persuaded to release Galen after receiving a report that Asclepius was against the project. He was left behind to act as physician to the imperial heir Commodus . It was here in court that Galen wrote extensively on medical subjects. Ironically, Lucius Verus died in 169, and Marcus Aurelius himself died in 180, both victims of the plague. Galen was the physician to Commodus for much of the emperor's life and treated his common illnesses. According to Dio Cassius 72.14.3–4, in about 189, under Commodus' reign,
15875-884: Was principally influenced by the then-current theory of the four humors : black bile, yellow bile, blood, and phlegm, as first advanced by the author of On the Nature of Man in the Hippocratic corpus . Galen's views dominated and influenced Western medical science for more than 1,300 years. His anatomical reports were based mainly on the dissection of Barbary apes . However, when he discovered that their facial expressions were too much like those of humans, he switched to other animals, such as pigs . While dissections and vivisections on humans were practised in Alexandria at this time, Galen did not have Imperial permission to perform his own, and had to use animals instead. Galen would encourage his students to go look at dead gladiators or bodies that washed up in order to get better acquainted with
16002-419: Was the basis of his criticism of the doctors who proceeded alogos and askeptos." However, Eudemus warned Galen that engaging in conflict with these physicians could lead to his assassination. "Eudemus said this, and more to the same effect; he added that if they were not able to harm me by unscrupulous conduct they would proceed to attempts at poisoning. Among other things he told me that, some ten years before,
16129-458: Was the heart and the arteries, which Galen believed to be responsible for providing life-giving energy. The last theorized system was the liver and veins, which Galen theorized were responsible for nutrition and growth. Galen also theorized that blood was made in the liver and sent out around the body. One of Galen's major works, On the Doctrines of Hippocrates and Plato , sought to demonstrate
