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

is stimulated by light waves. This conceptualization 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 the accurate and deep individual's understanding of one's perception and thinking.''(sic)'' 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

Peripheral awareness refers to the human ability to process information regarding all five senses at 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 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.

Basic awareness

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 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

Basic interests

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 a piece of food or pursuing a potential mate.


Changes in awareness

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 the

Communications and information systems

In cooperative settings, awareness is a term used to denote "knowledge created through 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 a set of characteristics: * Knowledge about the state of some environment * Environments are continually changing, therefore awareness knowledge must be constantly maintained * Individuals interact with the environment, and maintenance of awareness is accomplished through this interaction. * Generally part of some other activity, making it a secondary goal to the primary goal of the activity. Different categories of awareness have been suggested based on the type of information being obtained or maintained: * Informal awareness – the sense of who's around and what are they up to; information you might know from being collocated with an individual * Social awareness – the information you maintain about a social or conversational context. This is a subtle awareness maintained through non-verbal cues, such as eye contact, facial express, etc. * Group-structural awareness – the knowledge of others roles, responsibilities, and status in a group. It is an understanding of group dynamics and the relationship another individual has to the group. * Workspace awareness – awareness with a focus on the workspace's influence and mediation of awareness information, particularly the location, activity, and changes of elements within the workspace. 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 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 (

), 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 the awareness to context features of an operational target as well as to the context of an operational area.


Covert awareness

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 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.


Awareness versus attention

Some scientists have proposed that awareness is closely related and in some ways synonymous with
attention Attention or focus, is the concentration of awareness on some phenomenon to the exclusion of other stimuli. It is the selective concentration on discrete information, either subjectively or objectively. William James (1890) wrote that "Atte ...
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.Wyart V, Tallon-Baudry C (2008) Neural dissociation between visual awareness and spatial attention.
