Exam 3: Perception

In some areas of the cortex,some __________ cells fire maximally only in response to very specific shapes (e.g. ,a hand or a face).

Someone with this hereditary disorder is born with no cones in the retina and they rely solely on their rods for vision.

__________ refers to the perception that a given object remains the same even when the immediate sensation of the object changes.

When someone approaches us,we do not experience the person becoming larger as he or she comes closer,despite the fact that the retinal image is enlarging dramatically.This phenomenon is called

This particular type of context effect occurs when recognition of a target line that is part of a 3-D drawing is identified more accurately than when the line is part of a disjoined 2-D pattern.

These cues about depth are represented in just two dimensions and can be seen with just one eye.

List and then explain the function of the various layers of the retina.

The form of this particular mental representation is stored in a manner that is independent of the objects appearance to the observer.

Our eyes are constantly moving because it is the change in stimulation that leads to accurate perception;What occurs when a situation is created that leads to a constant stimulation of cells in the retina?

Define akinetopsia and achromatopsia.

These short and thick photoreceptors work well in situations in which the light is bright.

The __________ approach is based on the notion that the whole differs from the sum of its individual parts.

A pandemonium model,based on the notion that metaphorical "demons" with specific duties receive and analyze the features of a stimulus,is an example of a __________ theory of form perception.

This hypothesis suggests that there are two distinct visual pathways in the brain;one pathway is important for identifying the object and the other for identifying the function of the object.

This part of the eye allows for light to pass through it and serves as protection for the eye.

Transduction of electromagnetic light energy into neural electrochemical impulses occurs in this part of the eye.

This type of agnosia,due to a failure in perceptual processing,results in a failure to recognize an object.
