Q

________ is more than just the pattern of light and dark on the retina.

A

Visual perception

29
Q

_________ is determined by specific organizing principles.

A

Perception

30
Q

Points that when connected, result in straight or smoothly curving lines are seen as belonging together and the lines tend to be seen in such a way as to follow the smoothest path.

A

Good Continuation

31
Q

Objects that are overlapped by other objects are perceived as continuing behind the overlapping object.

A

Good Continuation

32
Q

A

Prägnanz

33
Q

The perceptual field and objects within it will take on the simplest and most encompassing structure permitted by the given conditions.

A

Prägnanz or Principle of Simplicity

34
Q

Similar things appear to be grouped together.

A

Similarity

35
Q

Grouping may occur due to the similarity of size, shape, or orientation.

A

Similarity

36
Q

___________ (1912) describes the principles as Intrinsic Laws which implies that the organizing principles are built into the system.

A

Wertheimer

37
Q

Although a person’s experience can influence perception, the role of experience is minor compared to the perceptual principles.

A

Intrinsic Laws

38
Q

Opposite to Helmholtz Likelihood principle which proposes that our knowledge of the environment enables us to determine what is most likely to have created the pattern on the retina.

A

Intrinsic Laws

39
Q

Modern perceptual psychologists, agreeing with Helmholtz see our experience with the environment as a central component of perception.

A

Intrinsic Laws

40
Q

Modern cognitive psychologists introduced the idea that perception is influenced by our knowledge of ____________________.

A

Regularities in the Environment

41
Q

Characteristics of the environment that occur frequently.

Ex. Blue is associated with the open sky. Landscapes are often green and smooth, and buildings contain horizontal and vertical lines.

A

Regularities in the Environment

42
Q

Two types of regularities:

A

Physical and Semantic

43
Q

Regularly occurring physical properties of the environment.

A

Physical Regularities

44
Q

People can perceive horizontals and verticals more easily than other orientations

A

OBLIQUE EFFECT

45
Q

Human-made environments such as buildings contain lots of horizontals and verticals and also natural environments such as trees and plants are more likely to be vertical or horizontal than slanted

A

OBLIQUE EFFECT

46
Q

Assumes that light is coming from above because the light in our environment including the sun, and most artificial light usually comes from above.

49
Q

Knowledge of what a given scene
typically contains.

A

SCENE SCHEMA

50
Q

A

SCENE SCHEMA

51
Q

Bayesian Inference was named after ________________

A

Thomas Bayes

52
Q

Thomas Bayes proposed that our estimate of the probability of an outcome is determined by 2 factors:

A
  1. PRIOR PROBABILITY or Prior
  2. LIKELIHOOD of the outcome or likelihood.
53
Q

It is our initial belief about the probability of an outcome

A

PRIOR

54
Q

An extent to which the available evidence is consistent with the outcome.

A

LIKELIHOOD

55
Q

It involves a mathematical procedure in which the prior probability is multiplied by the likelihood to determine the probability of the outcome.

A

Bayesian inference

56
Q

People start with _____________ the use additional evidence to update this initial belief about the probability of a certain outcome and reach a conclusion.

A

prior probability

57
Q

It is used by researchers to develop computer vision systems that can apply knowledge about the environment to more accurately translate the pattern of stimulation on their sensors into conclusions about the environment.

A

Bayesian inference

58
Q

Comparison of the 4 approaches

________, ________, and ________ all have a common idea:
1. We use data bout the environment, gathered through our past experiences in perceiving, to determine what is out there.

  1. Top-down processing is an important part of these approaches.
A

Helmholtz, Regularities, and Bayes

59
Q

Comparison of the 4 approaches

_________ emphasized the idea:
1. The principles of organization are built in.

  1. They acknowledged that perception is affected by experiences but argued that building principles can override experience thereby assigning bottom-up processing a more central role in perception.
A

Gestalt

60
Q

Comparison of the 4 approaches

__________________ pointed out that the principles of organization in fact have been created by experience.

A

Modern cognitive psychologists

61
Q

Experience shapes the way neurons respond.

A

Neurons and Knowledge About the Environment

62
Q

Experiencing certain stimuli over and over again can shape the way neurons respond in perceptual systems.

A

Neurons and Knowledge About the Environment

63
Q

The brain is changed or shaped by its exposure to the environment so it can perceive the environment more efficiently.

A

Experience-dependent plasticity

64
Q

Using fMRI, they found out that the temporal lobe called the ______________ (FFA) contains many neurons that respond best to faces and can be measured by its level of activity as well as other complex objects.

A

fusiform face area

65
Q

The brain’s functioning can be tuned to operate best within a specific environment. Regular exposure to stimuli can cause neurons to become adapted to respond best to these regularities.

A

Experience-dependent plasticity

66
Q

___________ helps us perceive objects in the environment more accurately. Some aspects may not be apparent in a single viewpoint.

A

Movement

67
Q

The visual signals that give us our experience of objects and events in the world are not the same ones that control our actions.

A

Movement Facilitates Perception

68
Q

Even a simple action like picking a coffee cup
involves several areas of the brain that coordinate their activity to create perceptions and behavior.

A

Movement Facilitates Perception

69
Q

Role of Culture in Perception

____________ cultures are more likely to engage in context-independent analytic perceptual processes.

A

Western

70
Q

Role of Culture in Perception

___________ cultures are more inclined to employ context-dependent holistic perceptual processes. Asians are more interdependent and relationships are highly valued.

A

East Asian

71
Q

TRUE or FALSE
Our perception is not fixed and universal.
