Awareness, in philosophy and psychology , is a perception or knowledge of something. The concept is often synonymous to consciousness . However, one can be aware of something without being explicitly conscious of it, such as in the case of blindsight .
46-447: Aware is the adjectival form of awareness , the perception of or reaction to an event. It may also refer to: AWARE may be the acronym for: Awareness may refer to: Awareness The states of awareness are also associated with the states of experience so that the structure represented in awareness is mirrored in the structure of experience. Awareness is a relative concept . It may refer to an internal state, such as
92-462: A brain function but involves the entire body. He suggests that the brain works in tandem with older biological systems like the endocrine and immune systems, emphasizing a holistic view of consciousness . 2. Homeostasis as Central: Damasio’s theory places homeostasis at the core of consciousness, proposing that consciousness evolved to help organisms maintain internal stability, which is crucial for survival . 3. Microbiome Influence: Damasio highlights
138-495: A crucial role in shaping our conscious experience. This theory emphasizes the importance of the body and its physiological processes in the emergence of consciousness. Damasio's three layered theory is based on a hierarchy of stages, with each stage building upon the last. The most basic representation of the organism is referred to as the Protoself, Core Consciousness, and Extended Consciousness. Damasio's approach to explaining
184-477: A different view of how emotion is connected to general cognition. They place emotionality on a similar level as that of other cognitive states. (In fairness, both Dyer's and Damasio's models concur on this point, ie that emotionality is not isolated to a particular layer within the tri-level framework). Earlier less sophisticated models placed the emotions strictly within the Limbic circuits, where their primary role
230-510: A dynamic neural map ultimately posits that we are the instantaneous configuration of a neural state in the present moment, rather than the supporting biological construct. I.e., our conscious identity is the software, not the hardware, even though our unique hardware constrains how we operate as the software. A common criticism stems from the fact that both knowing and feeling can be processed with equal success without conscious awareness, as machines, for instance, do, and those models do not explain
276-411: A feeling that they cannot label or describe, a phenomenon that is especially common in pre-verbal infants. Due to this discovery, medical definitions of brain death as a lack of cortical activity face a serious challenge. Throughout the brain stem, there are interconnected regions that regulate eye movement that are also involved in organizing information about what to do next, such as reaching for
322-400: A friend, peripheral awareness will allow for alertness to potential hazards such as cars or pedestrians coming into proximity that may not have been noticed otherwise. Studies have shown having peripheral awareness enhances overall cognition. By improving peripheral awareness, overall quality of life and productivity will subsequently be improved. Popular ideas about consciousness suggest
368-529: A historical series: evolutionary (ethological), physiological, neurological, and cognitive. Note that no current theory of emotion falls strictly within a single category, rather each theory uses one approach to form its core premises from which it is then able to extend its main postulates. Damasio's tri-level view of the human mind, which posits that we share the two lowest levels with other animals, has been suggested before. For example, see Dyer ( www.conscious-computation.webnode.com ). Dyer's triune expansion
414-408: A painful workplace injury (fear, threat to well-being) can coexist with our (high-level) feeling of anger and indignation at the co-worker who failed to follow safety guidelines. A careful reading of Damasio's work reveals that he distinguishes his theories from those of his predecessors, in how the formalistic elements interact with each other in a dynamically integrated system. E.g, the suggestion of
460-432: A perspective that cognition is a process present at organic levels that we do not usually consider to be aware. Given the possible relationship between awareness and cognition , and consciousness , this theory contributes an interesting perspective in the philosophical and scientific dialogue of awareness and living systems theory . In cooperative settings, awareness is a term used to denote "knowledge created through
506-457: A piece of food or pursuing a potential mate. The ability to consciously detect an image when presented at near-threshold stimulus varies across presentations. One factor is "baseline shifts", due to top down attention that modulates ongoing brain activity in sensory cortex areas that affects the neural processing of subsequent perceptual judgments. Such top down biasing can occur through two distinct processes: an attention driven baseline shift in
SECTION 10
#1732783863232552-467: A set of characteristics: Different categories of awareness have been suggested based on the type of information being obtained or maintained: These categories are not mutually exclusive, as there can be significant overlap in what a particular type of awareness might be considered. Rather, these categories serve to help understand what knowledge might be conveyed by a particular type of awareness or how that knowledge might be conveyed. Workspace awareness
598-448: A visceral feeling, or on external events by way of sensory perception. It is analogous to sensing something, a process distinguished from observing and perceiving (which involves a basic process of acquainting with the items we perceive). Awareness can be described as something that occurs when the brain is activated in certain ways, such as when the color red is seen once the retina is stimulated by light waves . This conceptualization
644-413: Is a direct report of one's experience. In this state, emotion begins to manifest itself as second-order neural patterns located in subcortical areas of the brain. Emotion acts as a neural object, from which a physical reaction can be drawn. This reaction causes the organism to become aware of the changes that are affecting it. From this realization, springs Damasio's notion of “feeling”. This occurs when
690-416: Is a result of mental patterns which are caused by an interaction with internal or external stimulus. A relationship is established, between the organism and the object it is observing as the brain continuously creates images to represent the organism's experience of qualia. Damasio's definition of emotion is that of an unconscious reaction to any internal or external stimulus which activates neural patterns in
736-400: Is able to recognize that its thoughts are its own, and that they are formulated in its own perspective. It develops a momentary sense of self, as the brain continuously builds representative images, based on communications received from the Protoself. This level of consciousness is not exclusive to human beings and remains consistent and stable throughout the lifetime of the organism The image
782-412: Is born. The brain continues to present nonverbal narrative sequence of images in the mind of the organism, based on its relationship to objects. An object in this context can be anything from a person, to a melody, to a neural image. Core consciousness is concerned only with the present moment, here and now. It does not require language or memory, nor can it reflect on past experiences or project itself into
828-506: Is clinically measured by the ability to follow commands -either verbally, or behaviorally. Awareness was detected by asking participants to imagine hitting a tennis ball and to imagine walking from room to room in their house while in the scanner. Using this technique, a patient who fulfilled all of the clinical criteria for the vegetative state was shown to be covertly aware and able to willfully respond to commands by looking at their brain activity. Some scientists have proposed that awareness
874-580: Is closely related and in some ways synonymous with attention while others have argued that they are different. There is evidence to demonstrate that awareness and attention have distinct neural correlates, though the majority of research analyses the attention, awareness, and perception of only visual stimuli. [REDACTED] The dictionary definition of presence of mind at Wiktionary Extended consciousness Developed in his (1999) book, "The Feeling of What Happens", Antonio Damasio 's theory of consciousness proposes that consciousness arises from
920-405: Is compared to Damasio's- 1. sensorimotor stage (c.f. Damasio's Protoself) 2. spatiotemporal stage (Core-Consciousness) 3. cognolinguistic stage (Extended Consciousness) An important feature of Damasio's theory (one that it shares with Dyer's theory) is the key role played by mental images, consciously mediating the information exchange between endocrine and cognitive. Ledoux and Brown have
966-427: Is constantly updated as the brain receives new stimuli from the body, and it forms the foundation for the development of more complex forms of consciousness. Damasio asserts that the protoself is signified by a collection of neural patterns that are representative of the body's internal state. The function of this 'self' is to constantly detect and record, moment by moment, the internal physical changes that affect
SECTION 20
#17327838632321012-427: Is crucial in this process. Modern systems theory maintains that humans, as living systems, not only have awareness of their environment but also self-awareness particularly with their capability for logic and curiosity. Efforts to describe consciousness in neurological terms have focused on describing networks in the brain that develop awareness of the qualia developed by other networks. As awareness provides
1058-414: Is developed gradually over time. Working memory is necessary for an extensive display of items to be recalled and referenced. Linguistic areas of the brain are activated to enhance the organism's experience, however, according to the language of thought hypothesis , language would not be necessarily required. Damasio's theory of consciousness has been met with criticism for its lack of explanation regarding
1104-437: Is gaining momentum with the growth of ubiquitous computing. First defined by networked work positions ( network location awareness ), it has been extended to mobile phones and other mobile communicable entities. The term covers a common interest in whereabouts of remote entities, especially individuals and their cohesion in operation. The term of context awareness is a superset including the concept of location awareness. It extends
1150-565: Is of particular interest to the CSCW community, due to the transition of workspaces from physical to virtual environments. While the type of awareness above refers to knowledge a person might need in a particular situation, context awareness and location awareness refer to information a computer system might need in a particular situation. These concepts of large importance especially for AAA ( authentication , authorization , accounting ) applications. The term of location awareness still
1196-502: Is posited due to the difficulty in developing an analytic definition of awareness or sensory awareness. Awareness is also associated with consciousness in the sense that it denotes a fundamental experience such as a feeling or intuition that accompanies the experience of phenomena. Specifically, this is referred to as awareness of experience. Mocenni C. and Bizzarri F. wrote: "The awareness literature can be organized around three core concepts: cognitive awareness, which corresponds to
1242-416: The alpha waves , and a decision bias reflected in gamma waves . Outside of the field of neuroscience , Humberto Maturana and Francisco Varela contributed their Santiago theory of cognition in which they wrote: Living systems are cognitive systems, and living as a process is a process of cognition. This statement is valid for all organisms, with or without a nervous system. This theory contributes
1288-431: The homeostasis of the organism. Protoself does not represent a traditional sense of self; rather, it is a pre-conscious state, which provides a reference for the core self and autobiographical self to build from. As Damasio puts it, "Protoself is a coherent collection of neural patterns, which map moment-by-moment the state of the physical structure of the organism" (Damasio 1999). Multiple brain areas are required for
1334-414: The accurate and deep individual's understanding of one's perception and thinking. The second perspective argues that awareness is multilevel considering both conscious and unconscious, with an end-stage of awareness... The third considers awareness concerning the recognition of the feelings of others ." Peripheral awareness refers to the human ability to process information regarding all five senses at
1380-576: The awareness to context features of an operational target as well as to the context of an operational area. Covert awareness is the knowledge of something without knowing it. The word covert means not openly shown, engaged in. Some patients with specific brain damage are, for example unable to tell if a pencil is horizontal or vertical. Patients who are clinically in a vegetative state (show no awareness of their surroundings) are found to have no awareness but they are able to sometimes detect covert awareness with neuro imaging (fMRI). The presence of awareness
1426-672: The brain can assimilate. Within an attenuated system of awareness, a mind might be aware of much more than is being contemplated in a focused extended consciousness . Basic awareness of one's internal and external world depends on the brain stem . Bjorn Merker , an independent neuroscientist in Stockholm, Sweden, argues that the brain stem supports an elementary form of conscious thought in infants with hydranencephaly . "Higher" forms of awareness, including self-awareness , require cortical contributions, but "primary consciousness" or "basic awareness" as an ability to integrate sensations from

1472-460: The brain. ‘Feeling’ emerges as a still unconscious state which simply senses the changes affecting the Protoself due to the emotional state. These patterns develop into mental images, which then float into the organism's awareness. Put simply, consciousness is the feeling of knowing a feeling. When the organism becomes aware of the feeling that its bodily state (Protoself) is being affected by its experiences, or response to emotion, Core Consciousness
1518-533: The development of consciousness relies on three notions: emotion , feeling , and feeling a feeling. Emotions are a collection of unconscious neural responses that give rise to feelings. Emotions are complex reactions to stimuli that cause observable external changes in the organism. A feeling arises when the organism becomes aware of the changes it is experiencing as a result of external or internal stimuli. Antonio Damasio’s work on consciousness : 1. Holistic Approach: Damasio argues that consciousness isn’t just
1564-432: The environment with one's immediate goals and feelings in order to guide behavior springs from the brain stem which human beings share with most vertebrates . Psychologist Carroll Izard emphasizes that this form of primary consciousness consists of the capacity to generate emotions and awareness of one's surroundings, but not an ability to talk about what one has experienced. In the same way, people can become conscious of
1610-517: The future. When consciousness moves beyond the here and now, Damasio's third and final layer emerges as Extended Consciousness. This level could not exist without its predecessors, and, unlike them, requires a vast use of conventional memory. Therefore, an injury to a person's memory center can cause damage to their extended consciousness, without hurting the other layers. The autobiographical self draws on memory of past experiences which involves use of higher thought. This autobiographical layer of self
1656-538: The generation of conscious experiences by the brain. Researchers have posited that the brain's interaction with the body alone cannot account for the complexity of conscious experience, and that additional factors must be considered. Furthermore, the theory has been criticized for its inadequate treatment of the concept of self-awareness and its lack of a clear method of measuring consciousness, which hinders empirical testing and evaluation. Theories of emotion currently fall into four main categories which follow one another in
1702-417: The interaction of an agent and its environment — in simple terms 'knowing what is going on'". In this setting, awareness is meant to convey how individuals monitor and perceive the information surrounding their colleagues and the environment they are in. This information is incredibly useful and critical to the performance and success of collaborations. Awareness can be further defined by breaking it down into
1748-452: The interactions between the brain , the body, and the environment. According to this theory, consciousness is not a unitary experience, but rather emerges from the dynamic interplay between different brain regions and their corresponding bodily states. Damasio argues that our conscious experiences are influenced by the emotional responses that are generated by our body's interactions with the environment, and that these emotional responses play
1794-440: The materials from which one develops subjective ideas about their experience, it is said that one is aware of one's own awareness state. This organization of awareness of one's own inner experience is given a central role in self-regulation . Neural systems that regulate attention serve to attenuate awareness among complex animals whose central and peripheral nervous systems provide more information than cognitive areas of
1840-447: The patterns contributing to emotion manifest as mental images , or brain movies. When the body is modified by these neural objects, the second layer of self emerges. This is known as core consciousness. Sufficiently more evolved is the second layer of Damasio's theory, Core Consciousness. This emergent process occurs when an organism becomes consciously aware of feelings associated with changes occurring to its internal bodily state; it
1886-423: The periphery of attention, such as acknowledging the distant sounds of people outside while sitting indoors and concentrating on a specific task, such as reading. Peripheral vision is defined as the perception of visual stimuli at or near the edge of the field of vision. This type of awareness allows one to be prepared to respond to unexpected events. For example, when walking down a busy street while talking to

1932-404: The phenomenon describes self-awareness, the condition of being aware of oneself. Modern systems theory , which offers insights into how the world works through an understanding that all systems follow system rules, approaches self-awareness within its understanding of how large complex living systems work. According to Gregory Bateson , the mind is the dynamics of self-organization and awareness
1978-421: The protoself is the first stage in the hierarchical process of consciousness generation. Shared by many species, the protoself is the most basic representation of the organism, and it arises from the brain's constant interaction with the body. The protoself is an unconscious process that creates a "map" of the body's physiological state, which is then used by the brain to generate conscious experience. This "map"
2024-477: The protoself to function. Namely, the hypothalamus , which controls the general homeostasis of the organism, the brain stem , whose nuclei map body signals, and the insular cortex , whose function is linked to emotion. These brain areas work together to keep up with the constant process of collecting neural patterns to map the current status of the body's responses to environmental changes. The protoself does not require language in order to function; moreover, it

Dual Mind Registers: He distinguishes between two mental registers: one for cognitive functions like reasoning, and another for emotions and feelings, which are tied to the body’s state . According to Damasio's theory of consciousness,
2116-456: Was to consciously respond to, as well as cause responses within, the hypothalamus, the interface between intentional mind states and metabolic (endocrine) body states. Emotionality is demonstrably a global mind state, just like consciousness. For example, we can be simultaneously aware of (low-level) a pain (low-level) in our body, and an idea (high level) that enters our imagination (working memory). Likewise, our (low-level) emotional reaction to
