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]
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 terms partially sighted, low vision, legally blind and totally blind are used by schools, colleges, and other educational institutions to describe students with visual impairments. [21] They are defined as follows: Partially sighted indicates some type of visual problem, with a need of person to receive special education in some cases.
They also cannot form associations between objects or assign meaning to objects. [20] C.K. makes many mistakes when trying to identify objects. For example, he called an abacus "skewers on a kebab" and a badminton racquet a "fencer's mask". A dart was a "feather duster" and a protractor was mistaken for a "cockpit".
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 ...
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.
The Riddoch syndrome is a term coined by Zeki and Ffytche (1998) in a paper published in Brain. [1] The term acknowledges the work of George Riddoch who was the first to describe a condition in which a form of visual impairment, caused by lesions in the occipital lobe, leaves the sufferer blind but able to distinguish visual stimuli with specific characteristics when these appear in the ...
Losing sight of the strategic construct that a measure is intended to represent, and subsequently acting as though the measure is the construct of interest. Teleological Bias The tendency to engage in overgeneralized ascriptions of purpose to entities and events that did not arise from goal-directed action, design, or selection based on ...
