Question

Quizplus · Accepted Answer

D.F.'s ability to grasp the block despite being unable to report its width suggests that she has blindsight, which is the ability to respond to visual stimuli without conscious perception. This indicates that she has some residual functioning in the visual pathway, even though she is unable to consciously process the information. The other answer choices (the cocktail party effect, selective attention, and inattentional blindness) do not adequately explain D.F.'s experience.
