Exam 3: Perception

A study on pattern perception looked at stimuli in which a single "larger" letter was constructed of smaller letters (e.g. ,using small "s" letters to make a large "H").In this study,participants were asked to identify the individual components (small letters)or identify the large letter.When the small letters were positioned close together,in general,participants were faster at identifying the larger letter versus the smaller letters.This is known as

Suppose that for Halloween,you are enlisted to use your knowledge of depth perception to create a small room where the sense of depth is distorted.Describe briefly two depth cues and then explain how you would use these toward your goal.

What is the expert-individuation hypothesis?

When someone opens a door,we do not experience the door as becoming distorted in form,from a rectangle to a diamond to a flat,thin stripe,and the like.Rather,we observe the door as remaining in its original form.This phenomenon is called

This form of color deficiency is when a person has a difficult time with medium wavelengths had have a difficult time with green colors.

The Gestalt principles of form perception,including proximity,similarity,closure,continuity,and symmetry,all support the overarching law of

The law of __________ is a Gestalt principle asserting the perceptual tendency to perceive visual arrays in ways that most simply organize disparate elements into a stable and coherent form.

According to Hubel and Wiesel,__________ cells receive input from neural cells projected from the thalamus and then fire in response to lines of particular orientations and positions in the receptive field.These cells differ from one another in that each cell responses only to a specific line orientation.

__________ refers to a severe deficit in the ability to perceive sensory information,usually related to the visual sensory modality.

Compare and contrast the theory of constructive perception with the theory of direct perception.

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

__________ features are those that give a form its overall shape.

Explain and then compare the what/where hypothesis and the what/how hypothesis.

This concept suggests that we divide visual information into two parts in which some of the information appears closer and better defined while the rest of the information appears further away and "unhighlighted"

These long thin photoreceptors work well under situations in which light is dim.

A __________ refers to an exact model of a distinctive pattern or form,used as the basis for perception of patterns or forms.

In the sense of vision the work of James Gibson defines this as the informational medium.

Select one of the anomalies in color perception and describe how,if everyone had that,it would change our world and our view of the world.

These cues about depth are based upon the information received from both eyes.

This particular mental representation is such that the object is stored in the manner in which the object looks to the observer (object is represented in relationship to the individual).This is called a(n)
