Module 6.3 Physio Psych

No known type of brain damage causes a person to lose the ability to recognize one person without impairing the ability to recognize others. What inference can we draw from this fact?

No one cell is solely responsible for recognizing any one facial pattern

Area ____ is particularly important for color constancy.

V4

The fusiform gyrus would be most excited in which of the following cases?

a car salesman looking at a customer's face

The ability that you have to determine that your eyes are moving, instead of the room that you are in, is a function of which brain area?

area MST

Monkeys with damage to area V4 lose:

color constancy.

An individual suffers damage to the temporal cortex, but maintains an intact parietal cortex. This may result in an inability to:

describe the size or shape of objects they see.

The visual path in the parietal cortex is referred to as the:

dorsal stream.

Human newborns come into the world predisposed to pay more attention to _____ than any other stationary displays.

faces

In the visual system of the mammalian cerebral cortex, the dorsal stream is specialized for detecting ____, and the ventral stream is specialized for detecting ____.

location; shape

One might find cells that respond best to the movement of an object relative to its background in the:

medial superior temporal cortex.

Damage to the magnocellular pathway would most likely lead to the loss of:

motion perception.

A person with damage to V1, but not V4, would be able to perceive:

motion, but not shape or color.

The pathway associated with integrating vision and movement progresses from the occipital cortex to the:

parietal cortex.

Color perception depends MOSTLY on the:

parvocellular pathway.

Damage to the fusiform gyrus of the inferior temporal cortex results in:

prosopagnosia.

Damage to the dorsal stream may interfere with:

reaching out to grasp an object.

In addition to having difficulty recognizing faces, people with prosopagnosia may have difficulty:

recognizing different kinds of plants and animals

What difficulty does someone with prosopagnosia have?

recognizing faces

Cells in the inferior temporal cortex respond vigorously to their preferred shape:

regardless of its exact size or position on the retina.

People who suffer from prosopagnosia can recognize:

relatives and friends by the sound of their voices.

The ability to recognize that a door maintains its shape even though the shape of the image on the retina is changing is known as:

shape constancy.

When cells in the middle temporal cortex respond to visual stimuli, their response depends mostly on the:

speed and direction of movement.

Cells in the ____ prevent us from confusing eye movements with object movements.

ventral part of area MST

The visual paths in the temporal cortex collectively are referred to as the:

ventral stream.

An inability to recognize objects despite otherwise satisfactory vision is called:

visual agnosia.
