Q

What is attention in perception?

A

Largely depends on what we ‘select’ and how much focus/attention we direct to it

39
Q

What are key features of attention?

A

It is part of out higher (executive) thinking and decision making process.
We are able to ‘tune out’ irrelevant information and focus on what is important

40
Q

How do we select stimuli?

A

It’s unusual, intense, unexpected or stands out from its surroundings
We are motivated to or expect to encounter a particular stimulus

41
Q

What is controlled process?

A

Controlled processes involve information processing requiring conscious, alert awareness and mental effort in which the individual actively focuses their attention on achieving a particular goal.

42
Q

What is automatic processing?

A

Automatic processing requires little conscious awareness and mental effort, minimal attention and do not interfere with the performance of some activities.

43
Q

What are the three types of attention?

A

Sustained, Divided and Selective

44
Q

What is sustained attention?

A

Deep focus. Beneficial in learning new tasks/things

45
Q

What is divided attention?

A

Often referred to as multi-tasking. You don’t change from one task to another. Instead, you try and perform both tasks at the same time. Necessary for responding to important daily events.

46
Q

What is selective attention?

A

Choose to focus on a specific range of stimuli and ignore others. Can be intentional. Can be automatic.

47
Q

What is visual sensation and what does it involve?

A

Visual Sensation: is being aware of a visual stimulus. It involves:
Reception
Transduction
Transmission

48
Q

What is visual perception and what does it involve?

A

Visual Perception: is giving meaning to a visual stimulus. It involves
Selection
Organization
Interpretation

49
Q

What is reception? (Sensation)

A

Reception: Taking the stimulus in
Sensory receptors in sense organs detect and respond to external stimulus energy

50
Q

What is transduction? (Sensation)

A

Transduction: Converting the stimulus
The human sense organs take in 5 different forms of energy. Therefore, transduction must occur, where the sensory receptors convert the stimulus energy into electrochemical energy.

51
Q

What is transmission? (Sensation)

A

Transmission: From the receptor site to brain. The electrochemically charged neural impulses leave their receptor site and travel along specific neural pathways that connect to a specialized part of the brain.

52
Q

What is selection? (Perception)

A

Selection: Filtering information
The brain filters the stimuli through a process of selective attention.
Important features are selected for further processing. Unimportant features are ignored and receive no further processing

53
Q

What is organization? (Perception)

A

Organization: Creating a whole
The grouping of elements or features of stimuli to form a whole that can be given meaning. The brain assembles the selected impulses into a pattern or form that can be recognized

54
Q

What is interpretation? (Interpretation)

A

Interpretation: Understanding the stimuli
The brain interprets these patterns or wholes and gives them meaning so we know what they represent in the external world.

55
Q

What is perception?

A

Perception is a psychological activity that gives meaning to the stimuli our sense organs detect that helps us understand the world. Perception occurs in the brain.

56
Q

What are the two basic types of processing?

A

Bottom-Up processing and Top-down Processing

57
Q

What is bottom-up processing?

A

We receive sensory information and do not rely on prior experience to interpret it. Built upward. Start from the sensory information and work from there
Starts with processing low level features (tiny details). Experience the stimulus first analyse it later.

58
Q

What is top-down processing?

A

Using pre-existing knowledge and expectations to interpret sensory information. Brain formulates a perceptual hypothesis based on what we know and anticipates what will come next (an educated guess).

59
Q

What are schemas?

A

Concepts which assist us in identifying patterns in new stimuli so we may quickly organize sensory data to create a meaningful perception

60
Q

What is the bio-psycho-social approach?

A

This approach says that there is an interaction between biological, psychological and social factors which influence our perception.

61
Q

What are some biological factors? (Bio-psycho-social approach)

A

Focus on physical and genetic factors that can influence vision:
Genetics
Age
Binocular and Monocular Depth Cues
Pictorial Depth Cues

62
Q

What are some psychological factors? (Bio-psycho-social approach)

A

Visual perception principles- Gestalt and Visual Constancies
Perceptual Set

63
Q

What is depth perception?

A

Is the process of perceiving the world in three dimensions, despite the two-dimensional retinal image we receive

Is achieved through the use of depth cues, which are sources of information from within our body (primary or internal cues) or the environment (secondary or external cues)

64
Q

What are the categories for depth perception?

A

Binocular Depth Cues and Monocular Depth Cues

65
Q

Binocular Depth Cues

A

Requires the combined information from both eyes. Convergence and retinal disparity.

66
Q

Monocular Depth Cues

A

Requires information from one eye only, that is, each eye can operate independently of the other eye. Accommodation and pictorial depth cues.

67
Q

Binocular- Convergence

A

Involves both eyes simultaneously turning inwards as an object moves closer (within approximately 7 metres) in order to maintain focus on the object.

The greater the tension, the closer the object

68
Q

Binocular- Retinal Disparity

A

As our eyes are 6-7 centimetres apart, each retina receives a slightly different view of the visual image.

The brain combines the two images and uses the differences to judge distance:

The greater the disparity (difference), the closer the object

69
Q

Monocular- Accommodation

A

Involves the ciliary muscles attached to the lens in each eye voluntarily or involuntarily relaxing or contracting to alter the shape of each lens in each eye so it can focus on objects at varying distances.

When an object is close (within approximately 3 metres), the ciliary muscles contract so your lens bulges and stays focused on the object.

70
Q

Monocular- Pictorial Depth Cues

A

Are depth cues that can be represented pictorially on a 2D surface.
*artists use them to create depth and distance on 2D surfaces such as paper.

71
Q

Pictorial Depth Cues (Examples)

A

Linear Perspective, Texture Gradient, Interposition, Relative Size and Height in the Visual Field

72
Q

Linear Perspective

A

Parallel lines appear to converge as they recede into the distance to an imaginary vanishing point (where they theoretically come together) at the horizon.

73
Q

Interposition

A

Closer objects will partially block the images of the further away objects.
Consequently, we perceive complete images to be closer than partially obscured objects.

74
Q

Texture Gradient

A

Close stimuli are perceived as more textured. Consequently, we perceive objects with little detail as being further away than objects with great detail

75
Q

Relative Size

A

Refers to the tendency to perceive the object that casts the larger retinal image as closer than the object that casts a smaller retinal image

Assumes that the two objects are similar in size

76
Q

Height in the Visual Field

A

Objects located closer to the horizon are perceived as being more distant than objects further from the horizon

Objects below the horizon, such as animals, trees and cars, are perceived as getting further away when their images move higher in the visual field.

77
Q

Psychological Influences

A

Focus on our brain making sense of information by automatically applying ‘rules’ to interpret visual stimuli.

78
Q

Two main psychological influences on vision

A

Visual perception principles - ‘rules’ we automatically apply to organise and interpret visual information. This includes Gestalt and visual constancies.

Perceptual set – which leads us to see what we expect to see.

79
Q

Gestalt Principles

A

Are ‘rules’ that the brain automatically uses to organize visual perceptual features into a meaningful whole or complete form by the simplest possible method.

The whole is greater than the sum of its parts.

80
Q

What do Gestalt Principles Include?

A

Figure Ground, Similarity, Closure and Proximity

81
Q

What is closure? (Gestalt Principles)

A

A tendency for incomplete elements in sensory information (or in the picture) to be ignored or mentally fill in gaps.
mentally grouping or perceiving the elements (of the picture) as a meaningful whole or complete figure.

82
Q

What is similarity? (Gestalt Principles)

A

Tendency to perceive elements or parts of a visual stimulus that have similar features (such as shape, size and colour) as forming a group, pattern, or a ‘meaningful unit’.

83
Q

What is proximity? (Gestalt Principles)

A

Tendency to perceive elements or parts of a visual stimulus that have similar features (such as shape, size and color) as forming a group, pattern, or a ‘meaningful unit’.

84
Q

What are visual constancies?

A

A group of perception principles that allow us to view objects as unchanging in terms of their actual size, shape, brightness and orientation regardless of changes to the image the object casts on the retina.

Four visual constancies that affect our interpretation of visual stimuli include:
Size
Shape
Brightness
Orientation

85
Q

What is perceptual set?

A

The readiness or predisposition to perceive stimuli in a particular way according to expectation. Factors that contribute to perceptual set include;
Past experience
Context
Motivation and emotional experience
Memory

86
Q

What are visual illusions?

A

Visual Illusions are consistent perceptual mistakes or perceptual distortion in interpreting a real sensory stimulus; that is, the perception consistently does not match the visual stimulus on the retina.

87
Q

What is agnosia?

A

Agnosia is a rare conditioncausedby a neurological disorder or damage to parts of thebrain.

It occurswhen a person’s perceptual processing is impaired, which limits their ability to make sense of sensoryinformation.

They can’trecognizeand identify objects, people, smells or sounds despitetheir senses workingnormally

88
Q

What is visual agnosia?

A

Visual agnosia is a loss of visual knowledge. The brain therefore can’t access the stored informationneeded for perception

89
Q

What are the causes of agnosia?

A

Agnosia is caused by damage along pathways that connect primary sensory processing areas in the brain (includingthe parietal, occipital and temporal lobes).

90
Q

Characteristics of visual agnosia?

A

Being unable to recognize faces but able to recognize other objects
seeing multiple objects but only recognizing one object at a time
being unable to name or describe familiar objects when looking at them.

91
Q

What is prosopagnosia?

A

Prosopagnosia (also known as face blindness) is a form of associative visual agnosia.

People with this disorder can’trecognize familiar faces (sometimes their own), facial differences, identify a person by name, or even whether they have seen them before!

92
Q

What is perception distortion?

A

Occurs when a person’s response to environmental stimuli is different from what is considered the normal response.

93
Q

What is Synesthesia?

A

Refers to a group of neurological conditions where information taken in by one sense is involuntarily experienced in a way normally associated with another sense.

94
Q

What is spatial neglect?

A

Spatial neglect is when a person tends to ignore the left or right side of their body or the left or right side of their visual space.
Spatial neglect is a cognitive impairment not a visual impairment.
