PSY302 Exam 2 Review

Front

What is occlusion in depth perception?

Back

Occlusion is a depth cue where one object blocks the view of another, indicating that the blocked object is further away.

Front

Define binocular disparity.

Back

Binocular disparity is the difference in the images received by the left and right eyes, which helps in depth perception.

Front

What evidence supports the connection between MT neurons and movement perception?

Back

Both lesioning and microstimulation studies provide evidence for the connection between MT neurons and movement perception.

Front

What is the motor signal in relation to eye muscles?

Back

The motor signal is the type of signal sent from the brain to the eye muscles to control eye movement.

Front

What are metamers in perception?

Back

Metamers are two stimuli that are physically different but perceptually identical.

Front

Explain the concept of convergence in depth perception.

Back

Convergence is a depth cue that involves the inward turning of the eyes when focusing on a nearby object.

Front

What is accommodation in visual perception?

Back

Accommodation is the process by which the eye changes its focus from distant to near objects by altering the shape of the lens.

Front

Define relative height in the context of depth perception.

Back

Relative height is a depth cue where objects positioned higher in the visual field are perceived as being further away.

Front

What role do MT neurons play in visual processing?

Back

MT neurons are involved in the perception of motion and are sensitive to the direction and speed of moving objects.

Front

What is the image displacement signal?

Back

The image displacement signal is a signal that indicates the movement of an image across the retina, helping in motion perception.
