Question

Quizplus · Accepted Answer

Blindsight is a phenomenon in which individuals with damage to the primary visual cortex (V1) are unable to consciously perceive visual stimuli but still have intact visual abilities that allow them to make visual responses, such as detecting the location or movement of an object. The individual may report feeling "blind" but be able to accurately guess the location or direction of an object in their visual field. Repetition blindness refers to the phenomenon of failing to detect a repeated occurrence of a stimulus, attentional blindness refers to the failure to notice an unexpected stimulus because attention is focused elsewhere, and change blindness refers to the difficulty of detecting minor changes in a visual scene when presented with a new version of the scene after a brief interruption.
