25
Transmission (Sensation)
The information is sent to the brain for perceptual processing
26
Visual Sensory System
The network that is involved in the sensation and perception of visual stimuli, including the eyes, the brain, and the neural pathways connecting them
27
Visual Perception
The process of becoming consciously aware of visual stimuli as a result of the interactions between the visual sensory system, and the individual’s internal and external environments
28
Gustatory Perception
The process of becoming consciously aware of flavour
29
Tastants
The sensory stimuli received in the form of chemical molecules that can be tasted
30
Gustatory Receptors
The sensory receptors for taste
31
Taste Buds
Clusters of gustatory receptors
32
Primary Gustatory Cortex
A sensory area in the parietal lobe responsible for receiving and processing tastes
33
Bottom-Up Processing (Definition)
Perception is determined by incoming sensory information, moving from specific stimulus information to general knowledge
34
Top-Down Processing (Definition)
Perception is driven by prior knowledge and expectations, moving from general knowledge to specific stimulus information
35
Schemas
The collection of basic knowledge about a concept or stimuli
36
Basic Bottom-Up Processing
Bottom-up processing ↓ Detect sensory stimuli (specific) ↓ Analyse specific features and combine them into a more complete form (general) ↓ Perception
37
Basic Top-Down Processing
Top-down processing ↓ Prior knowledge and expectations, such as schemas (general) ↓ Select features from sensory stimuli that align with prior knowledge and expectations (specific) ↓ Perception
38
Bottom-Up Processing (Explanation)
- Builds knowledge in real-time as the stimuli are received, allowing each of the elements to be perceived - Specific to general - Unfamiliar and complex
39
Top-Down Processing (Explanation)
- Uses prior knowledge to fit the incoming stimuli with similar previous understandings - General to specific - Familiar and less complex
40
Depth Cues
Visual cues that allow us to judge the distance and position of object and in their environment
41
Protanopia
Dark colour blindness, (eg. black with many shades of red)
42
Deuteranopia
Mid-colour blindness (eg. mid-reds with mid-greens)
43
Tritanopia
Light colour blindness (eg. light blues with greys)
44
Monocular Depth Cues
Rely on visual information perceived by just 1 eye.
45
Binocular Depth Cues
Rely on visual information perceived by both eyes.
46
Accommodation
The ability of the eye to change focus from near to distant objects and back again.
47
Motion Parallax
Uses our perception of movement to help us gauge how far away things are.
48
Pictorial Depth Cues
- Relative size - Height in visual field - Linear perspective - Interposition - Texture gradient
49
Relative size
The relative size of objects to one another in our visual field helps us to judge distance.
50
Height in Visual Field
In our visual field, the closer objects are to the horizon line, the further away they appear.
51
Linear Perspective
Our perspective of lines allows us to gauge distance.
52
Interposition
When objects overlap we perceive the object that is covered by another as being further away than the one obscuring it.
53
Texture Gradient
We rely on the use of texture to judge how far away objects are. More detail = Closer
54
Retinal Disparity
The difference, between the different images received on the retina of either eye.
55
Convergence
The strain on the eye muscles signals to our brains that something is up close.
56
Cultural Norms
Each culture has a unique way of perceiving visual stimuli.
57
Gestalt Principles
Guiding rules of perception that allow us to organise and group separate visual stimuli into a meaningful whole. 'The whole is greater than the sum of its parts'
58
Figure-ground Principle
Whether an image belongs in the fore-ground or back-ground
59
Similarity Principle
We mentally group objects that look alike.
60
Proximity Principle
We tend to see close-set objects as being in a group.
61
Closure Principle
Even if an object is missing parts, your brain will fill in the blanks and perceive a complete picture.
62
Fallibility
Refers to the quality of being prone to error or experiencing difficulties in judgement.
63
Perceptual Distortion
An error in the judgement or interpretation of sensory stimuli
64
Carpentered World
When we see the plain two-dimensional lines of an illusion, we automatically apply them to real three-dimensional objects in our world stored in our memory, such as the corners of rooms and buildings.
65
Agnosia
A disorder involving the loss or impairment of the ability to recognise familiar stimuli through the use of one or more senses, despite the senses functioning normally otherwise.
66
Apperceptive Visual Agnosia
Difficulty in perceiving visual information
67
Associative Visual Agnosia
Difficulty in identifying what object is being viewed
68
Synaesthesia
A perceptual phenomenon characterised by the experience of unusual perceptions in one sensory system after another sensory system has been activated
69
Characteristics of Synaesthesia
- Synaesthesia is automatic and cannot be controlled - Synaesthesia is generally experienced as a one-way process - Synaesthesia is usually consistent - The way that synaesthesia is experienced is unique to the individual - Synaesthesia is relatively common
70
Grapheme-colour Synaesthesia
- A person sees colours when looking at ordinary symbols, such as numbers and letters. - For example, an individual may perceive the letter ‘A’ to be blue.
71
Sound-colour Synaesthesia
- When sounds cause the secondary perception of colours. - For example, an individual may see the colour red when they hear a car horn.
72
Lexical-gustatory Synaesthesia
- When a person sees a word, a taste is triggered. - For example, an individual may taste garlic when reading the word ‘train’.
73
Spatial Neglect
An inability to perceive, report, or orient sensory information located within one side of space
