often termed as cognitive bias.

Q

Damaged in Dorsal Stream
“Where Pathway”
Patients with ______ fail to
reach accurately for objects,
particularly when they are
presented in peripheral vision

Ataxia results from a processing failure in the posterior parietal cortex, where sensorimotor information is processed. It is assumed that higher order processes are involved because most patients’ disorders are complex and
they can indeed grasp objects under certain circumstances

A

optic ataxia

20
Q

A phenomenon of visual perception that occurs when a stimulus undergoes a change without this being noticed by its observer.

Perceptual processes and change blindness play a significant role in accidents and efforts at accident prevention.

About 50% of all collision accidents are result of missing or delayed perception.

A

change blindness

21
Q

Provided a useful framework for studying
perception.
Gibson developed what he called an
“ecological approach” to the study of visual |
perception.

A

James Gibson

22
Q

Bottom-up processing occurs as our sensory receptors receive new sensory information and does not require the use of prior knowledge or experiences.

Therefore, they are data driven (i.e., stimulus-driven) theories.

A

Bottom up theories

23
Q

According to Gibson’s theory of _______, the information in our sensory receptors, including the sensory context, is all we need to perceive anything.

we do not need higher cognitive processes or anything else to mediate between our sensory experiences and

A

direct perception theory

24
Q

according to which perception is driven by
high-level cognitive processes, existing
knowledge, and the prior expectations that
influence perception.

_______ are hypotheses-driven

A

Top-down theories

25
Q

2 examples of the top down theory

A

typos
the stroop effect

26
Q

» a_____________ suggesting
perception is an active process driven by
cognition.

» Sensory information is combined with stored
knowledge about the world, constructing our
perception.

A

top down theory of perception

27
Q

The viewpoint of _____________ shows the central relation between perception and intelligence.

According to this viewpoint, intelligence is an
integrai part of our perceptual processing.

A

constructive or intelligent
perception

28
Q

_______ considers the appearance of an object relative to the viewer.

Descriptions of objects from a viewer-centered perspective detail their

appearance and position from the perspective of the speaker: an object is

“three feet away” and “horizontal” or “titled at about a twenty-degree

A

.viewer-centered representation

29
Q

____________ considers the appearance of
the object itself, regardless of the distance and angle from which it
is viewed.

descriptions from an object-centered perception consider the object
itself (the desk is rectangular and rounded on one end), or in
relation to other objects (the pencil is in the middle of the desk).

A
  1. object-centered representation
30
Q

The __________to form perception that was developed in Germany in the early 20th century is useful particularly for
understanding how we perceive groups of objects or even parts
of objects to form integral wholes.

A

Gestalt approach

31
Q

When perceiving a visual field, some
objects (figures) seem prominent, and
other aspects of the field recede into
the background (ground).

A

FIGURE-GROUND

32
Q

When we perceive an assortment of
objects, we tend to see objects that are
close to each other as forming a group.

A

PROXIMITY

33
Q

The principle of similarity states that
when things appear to be similar to
each other, we group them together.

A

SIMILARITY

34
Q

We tend to perceive smoothly flowing or continuous forms rather than disrupted or discontinuous ones

A

CONTINUITY

35
Q

We tend to perceptually close up, or complete, objects that are not, in fact, complete.

A

CLOSURE

36
Q

We tend to perceive objects as
forming mirror images about their
center.

A

SYMMETRY

37
Q

2 different pattern recognition system

A

FEATURE ANALYSIS SYSTEM
CONFIGURATIONAL SYSTEM

38
Q

The first system specializes in recognition of parts of objects” and in assembling those parts into distinctive wholes.

A

FEATURE ANALYSIS SYSTEM

39
Q

The second system specializes in recognizing larger configurations.

It is not well equipped to analyze parts of objects or the construction of the
objects. But it is especially well equipped to recognize configurations.

A

CONFIGURATIONAL SYSTEM

40
Q

the inability to recognize faces—would imply damage of some kind to
the configurational system.

Somebody with prosopagnosia can see the face of another person
and even recognize if that person is sad, happy, or angry.

But what he fails to recognize is whether that person being observed
is a stranger, his friend, or his own mother.

A

PROSOPAGNOSIA

41
Q

___________ refers to the tendency to perceive an object you are familiar with as having a constant shape, size, and brightness
despite the stimuli changes that occur.

A

Perceptual constancy

42
Q

Ability of an observer to perceive an object from various or changing distances where the object can appear to be different sizes, but then be able to recognize and perceive the object as it is and for its actual size.

A

SIZE CONSTANCY

43
Q

________ is the tendency for a familiar object’s shape to be perceived as constant when observed from various angles, positions
and orientations.

A

Shape constancy

44
Q

_________ is the ability to perceive the world in three dimensions (3D) and to judge the distance of objects.

A

Depth perception
