A patient with visual agnosia is looking at his house key. What will he most likely have difficulty with?

A) describing the key
B) identifying the object as a key
C) seeing the key
D) using the depth cues needed to insert the key into the lock

Visual agnosia is a type of perceptual disorder that affects the recognition of objects despite normal visual acuity. A person with this condition may have difficulty identifying objects by their shape, size, and orientation, even though they can see them clearly. Therefore, the patient in this scenario is most likely to have difficulty identifying the object as a key, rather than describing it or using the depth cues to insert it into a lock.
