Blindsight is the ability of people who are cortically blind to respond to visual stimuli that they do not consciously see due to lesions in the primary visual cortex, also known as the striate cortex or Brodmann Area 17. [1] The term was coined by Lawrence Weiskrantz and his colleagues in a paper published in a 1974 issue of Brain. [2]
Lawrence Weiskrantz FRS (28 March 1926 – 27 January 2018) was a British neuropsychologist.Weiskrantz is credited with discovering the phenomenon of blindsight, and with establishing the role of the amygdala in emotional learning and emotional behavior. [1]
In psychology and cognitive science, a memory bias is a cognitive bias that either enhances or impairs the recall of a memory (either the chances that the memory will be recalled at all, or the amount of time it takes for it to be recalled, or both), or that alters the content of a reported memory. There are many types of memory bias, including:
The following criteria are required to classify an event as an inattentional blindness episode: 1) the observer must fail to notice a visual object or event, 2) the object or event must be fully visible, 3) observers must be able to readily identify the object if they are consciously perceiving it, [3] and 4) the event must be unexpected and the failure to see the object or event must be due ...
The resulting perception is also known as vision, sight, or eyesight (adjectives visual, optical, and ocular, respectively). The various physiological components involved in vision are referred to collectively as the visual system , and are the focus of much research in linguistics , psychology , cognitive science , neuroscience , and molecular ...
Awareness, in psychology and philosophy, is a perception or knowledge of something. [1] The concept is often synonymous with consciousness. [2] However, one can be aware of something without being explicitly conscious of it, such as in the case of blindsight.
At an associative level, the meaning of an object is attached to the perceptual representation and the object is identified. [2] If a person is unable to recognize objects because they cannot perceive correct forms of the objects, although their knowledge of the objects is intact (i.e. they do not have anomia ), they have apperceptive agnosia.
The term was created by Emily Pronin, a social psychologist from Princeton University's Department of Psychology, with colleagues Daniel Lin and Lee Ross. [2] [better source needed] The bias blind spot is named after the visual blind spot. Most people appear to exhibit the bias blind spot.
