3. we are actively learning as we process multiple tasks at once.

Question 21

8A - Attention

Identify limitations of Divided Attention:

Answer 21

Limitation of divided attention source from multi-tasking as it requires individuals to divide their attention, preventing them from giving their full potential to just one task. Negatively impacting our performance when:
1. we have to stop a task that is not easy to resume
2. the tasks are less related and jumping between them is more disruptive to your attention
3. when tasks are more effortful, as they typically require more attention to be completed

Question 22

8A - Attention

Define Distractions:

Answer 22

Distractions refer to internal or external stimuli that draw an individuals attention away from the current task they are working on, where individuals find themselves constantly having to refocus their attention.

Question 26

8B - Perception

Explain how individuals absorb sensory information?

—–> Identify and Explain the steps

Answer 26

1. Reception ____ raw peices of information that are detected by an individuals sensory receptors E.g., 5 senses (taste/sound/smell/touch/sight) and sensory organs
2. Transduction ____ The captured information is converted into neural impulses E.g., visual info = photoreceptors in your eyes
3. Transmission ____ The neural impluses are transmitted to an individuals brain for processing (visual info = in this stage you are still not consiously aware of the objects present)
4. Selection ____ An individuals brain focuses on specific features of obtained information (any of 5 senses), while ignoring less prominent details
5. Organisation ____ The slescted feautures selected are re-grouped and cohesively arranged by your brain
6. Interpretation ____ The newly organised sensory information in interpreted, an individual is now able to contiously recognise the object, assigning meaning to it based on you past experiences and knowledge and then we decide how to behave in response

OR Sensory stimuli < sensory organs < neural impluse < brain < reaction

We are only ever aware of SOME sensory information despite it flooding our sensors

Question 39

8B - Perception

Identify the types of Perceptual Processing:

Answer 39

1. Bottom-up processing
2. Top-down processing

Question 40

8B - Perception

Define Bottom-up processing:

Answer 40

Bottom-up processing refers to a type of perception typically used when the information is unfamiliar or highly complex.
The sensory data is processed in real-time and moves up to the brain to be perceived and understood

Question 41

8B - Perception

Define Top-down processing:

Answer 41

Top-down processing requires no previous knowledge of the sensory stimuli as it is driven by prior knowledge and expectations.
Top-down processing involves sensory stimuli linked to information categories (schemas) stored in long term memory
It refers to moving from general knowledge to specific stimulus information
It is typically used when what is being perceived is relatively familiar and less complex

Question 42

8B - Perception

How do Top-down processing and Bottom-up processing work together?

Answer 42

Bottom-up processing starts with sensory input, where the brain builds up a perception by interpreting raw data from the senses.
Top-down processing uses prior knowledge, expectations, and experiences to interpret and give meaning to this sensory information.
Together, they allow us to recognize familiar objects and patterns quickly while also making sense of new stimuli.

Bottom-up provides the details, while top-down fills in gaps and adjusts perceptions based on what we already know.

Question 43

4. That are sent to the brain

Question 46

8C Visual Perception - Psychological Factors (depth Cues)

Identify and Define the types of Photoreceptors:

Answer 46

There are two types of photoreceptors located in the retina:
1. Rods allow someone to see in low levels of light, shaped like long cylinders (Night Vision), they allow peripheral vision
2. Cones allow someone to see colour and fine details in well-lit, shapped like cones (Day Vision), they don’t allow perpheral vision

Question 47

8C Visual Perception - Psychological Factors (depth Cues)

Where are Rods and Cones located in teh eye?

Red-Green colour blindness refers to when individuals struggle to tell the difference between the colours red and green.

Question 50

8C Visual Perception - Psychological Factors (depth Cues)

Define Blue-Yellow Colour Blindness:

Answer 50

Blue-Yellow colour blindness refers to when individuals struggle to tell the difference between the colours blue and green, and yellow and red.

Question 51

8C Visual Perception - Psychological Factors (depth Cues)

Define Complete Colour Blindness:

Answer 51

Complete colour blindness (also known as monochromacy), where people struggle to differentiate between colours at all, and often struggle to see clearly

Question 52

8C Visual Perception - Psychological Factors (depth Cues)

Define Myopia:

Answer 52

Myopia, or short/near-sightedness, refers to when your eye is a little too long or the front part of your eye, called the cornea, is too curved

Because of this shape, light that comes into your eye doesn’t focus correctly. Instead of focusing directly on the retina, which is at the back of your eye, the light focuses in front of it

This makes things that are far away look blurry. People with myopia can see things that are close up pretty well, but might need glasses or contacts to clearly see things that are further away

Question 53

8C Visual Perception - Psychological Factors (depth Cues)

Why we see the world in 3-D and not like a cartoon?

Answer 53

1. When we look at an object our eyes sends a two-dimensional image of the object to the brain.
2. The brain receives two slightly different images of the object from the left and right eyes
3. The visual cortex in the brain integrates the two images to create a single three-dimensional image of the object, also computing the differences between the two images to work out how far away the object is

Question 54

8C Visual Perception - Psychological Factors (depth Cues)

Define Depth Cues:

Answer 54

Depth cues rfere to visual signals that allow us to perceive the three-dimensional structure of the world from two-dimensional images, such as those on the retina.
Our brains use a combination of binocular and monocular cues to estimate depth and distance, creating a sense of three-dimensionality.

Question 55

8C Visual Perception - Psychological Factors (depth Cues)

Define Monocular Cues:

Answer 55

Monocular Cues refer to visual information recieved from both eyes together.

Question 56

8C Visual Perception - Psychological Factors (depth Cues)

Define Binocular Cues:

Answer 56

Binocular Cues refer to visual information recieved from each eye separately

Question 57

8C Visual Perception - Psychological Factors (depth Cues)

What are the types of Monocular Cues?

Answer 57

The three types of monocular depth cues are:
1. accommodation
2. motion parallax
3. pictorial depth cues

Question 58

8C Visual Perception - Psychological Factors (depth Cues)

Define Accomodation:

(Monocular Cues)

Answer 58

refers to the process by which the eye’s lens changes shape —bulging to focus on large, close-up objects and flattening to focus on distant objects. The brain receives information about these changes in the lens and uses it to infer the distance of objects from the eye, helping us perceive depth and distance with one eye.

Flattening = distant object

bulging = close up

Question 59

8C Visual Perception - Psychological Factors (depth Cues)

Define Motion Parallax:

(Monocular Depth)

Answer 59

Motion parallax refers to our perception of movement that helps us gauge how far away things are. This phenomenon helps us to measure depth: the less objects in our visual field move, the further they are away from us

less objects = further away

Question 60

8C Visual Perception - Psychological Factors (depth Cues)

Define Pictorial depth cues:
And Identify all types of Pictorial depth cues:

Answer 60

Pictorial depth cues are named as such because they are often manipulated by artists when painting or drawing a picture.

Pictorial depth cues include:
1. relative size
2. height in visual field
3. linear perspective
4. interposition (also known as overlap)
5. texture gradient

It is worth noting that, although they are depth cues, pictorial depth cues are considered psychological (cognitive) factors. Though they rely on the eye, their effects are interpreted within the brain.

Question 61

8C Visual Perception - Psychological Factors (depth Cues)

Define Linear Perspective:

(Monocular Depth Cues - Pictoral depth cues)

Answer 61

Linear Perspective has two main componements, including:
1. Convergence of Parallel Lines: In linear perspective, parallel lines, such as railroad tracks or a road, appear to converge as they recede into the distance. This convergence is interpreted by the brain as an indication of depth and distance

2. Size Constancy: As objects move further away, they appear smaller, but the brain maintains size constancy, understanding that the object’s actual size hasn’t changed.

Linear perspective helps maintain this constancy by providing contextual clues about distance

Question 62

8C Visual Perception - Psychological Factors (depth Cues)

Define Texture Gradient:

(Monocular Depth Cues - Pictoral depth cues)

Answer 62

Texture gradient is based on the observation that the texture of surfaces and objects appears to change with distance.

Closer objects have larger and more distinct texture elements, while those farther away have smaller and less distinct texture elements.

further = less texture

closer = more texture

Question 63

8C Visual Perception - Psychological Factors (depth Cues)

Define Interposition-Overlap-Occlusion:

(Monocular Depth Cues - Pictoral depth cues)

Answer 63

Interposition or occlusion refers to the way objects that partially cover or obscure other objects are perceived as being closer to the viewer.
Refers to the way objects that partially cover or obscure other objects are perceived as being closer to the viewer.

covering = closer**

**covered = further

Question 64

8C Visual Perception - Psychological Factors (depth Cues)

Define Height in the visual field:

(Monocular Depth Cues - Pictoral depth cues)

Answer 64

Based on the observation that objects positioned higher in the visual field are perceived as being further away compared to those positioned lower
Objects lower down from the horizon are perceived as being closer to the viewer
Objects higher up from the horizon are perceived as being further away from the viewer

high objects above horizon = further

low objects below horizon = closer

Question 65

8C Visual Perception - Psychological Factors (depth Cues)

Define Relative Size:

(Monocular Depth Cues - Pictoral depth cues)

Answer 65

The brain uses knowledge of the typical size of familiar objects to make judgments about distance

If two trees are visible and one appears smaller, it is perceived as being further away

Compares the size of objects based on the understanding that, when viewed from the same distance, larger objects are perceived as closer than smaller ones

smaller = further**

**larger = closer

Question 66

8C Visual Perception - Psychological Factors (depth Cues)

Define Binocular Depth Cues:

Answer 66

Binocular depth cues rely on the use of both eyes. There are two types of binocular depth cues:
1. retinal disparity
2. convergence

Question 67

8C Visual Perception - Psychological Factors (depth Cues)

Define Retinal disparity:

(Binocular Depth Cue)

Answer 67

Retinal disparity explains how our two eyes help us perceive depth and distance
Because our eyes are about 6-7 cm apart, each one sees a slightly different image of the world. The brain compares these two images, and the small differences between them (the retinal disparity) allow us to judge how far away objects are ​

The **greater the disparity, the closer the object is to us **

retinal disparity = small differences between two images (from each eye)

Question 68

8C Visual Perception - Psychological Factors (depth Cues)

Define Convergence:

(Binocular Depth Cue)

Answer 68

Convergence refers to a process that helps us see things in three dimensions and judge how far away they are

When you focus on something close to your face, like your finger, your eyes turn inward toward each other. This inward movement is called convergence

The closer the object, the more your eyes converge. Your brain uses the amount of convergence to figure out the distance of the object

This is why when you look at something far away, your eyes stay more parallel, and when you look at something close, your eyes cross a bit

convergence = eyes inward movement

far away = eyes parallel
close = eyes inwaed motion

Question 69

8C Visual Perception - Psychological Factors

Define Psychological Factors in terms of Visual Perception:

Answer 69

Psychological factors refer to internal factors pertaining to an individual’s mental processes, including their cognition, affect, thoughts, beliefs, and attitudes. Particularly relevant to visual perception is the mental process of cognition, due to the act of mentally processing the incoming stimuli

Question 70

8C Visual Perception - Psychological Factors

Define Visual Perception Principles:

Answer 70

Visual perception principles refer to
1. guiding rules that apply to incoming visual signals
2. make sense of our reality (combining visual signals in a systematic way)
3. apply these principles automatically and unconsciously
4. can make ourselves consciously aware of them.

Question 71

8C Visual Perception - Psychological Factors

Answer 73

The Gestalt principles include:
1. the proximity principle
2. the similarity principle
3. the figure-ground principle
4. the closure principle

Question 74

8C Visual Perception - Psychological Factors

Define the Proximity Principle:

Answer 74

The proximity principle refers to our brain’s tendency to group together items in an image based on their physical closeness to one another.

Rule: Group together items that are **physically close **to one another

Question 75

8C Visual Perception - Psychological Factors

Define the similarity Principle:

Answer 75

This principle reflects our brain’s tendency to group together parts of an image that are similar in some way. Elements of an image can be similar in their size, shape, colour, position and so on

Rule: Group together figures that look similar or are related to one another

Question 76

8C Visual Perception - Psychological Factors

Define the figure-background principle:

Answer 76

This principle involves our brain’s tendency to see some figures as being at the front of an image i.e. the ‘foreground’, and others as falling back into the ‘background’

Rule: Separate figures in an image by placing some in the foreground and some in the background.

Question 77

8C Visual Perception - Psychological Factors

Define the closure principle:

Answer 77

The closure principle refers to our brain’s ability to mentally complete images that are otherwise incomplete.

Rule: Fill in the empty spaces or gaps of an incomplete picture to create a whole

Question 78

8C Visual Perception - Psychological Factors

Define a Visuall Constancy:

Answer 78

Visual constancies refer to our ability to perceive visual objects as staying the same, even though they may appear to change or do change in our sensation

If we look at an object from another angle, position, or under different light conditions, we know that the object itself is not changing thanks to perception

Question 79

8C Visual Perception - Psychological Factors

Identify the 3 types of Visual Constancies:

Answer 79

Three visual constancies that affect our interpretation of visual stimuli include:
1. shape
2. size
3. brightness

Question 80

8C Visual Perception - Psychological Factors

Define size Constancy:

Answer 80

Size Constancy refers to the perception of an object’s size as constant, even when its distance from us changes.
For example, people walking away from us appear smaller in our field of vision, but we perceive them as remaining the same size.

Question 81

8C Visual Perception - Psychological Factors

Define Shape Constancy:

Answer 81

Size Constancy refers to the ability to perceive an object’s shape as stable, even when the angle from which we view it changes.
For example, a door appears rectangular whether it is open or closed, even though the angle might change the image on our retinas.

Question 82

8C Visual Perception - Psychological Factors

Define Brightness Constancy:

Answer 82

The Brightness Constancy refers to the perception of an object’s brightness or colour as remaining constant under varying lighting conditions.
For example, a grey sheet of paper looks grey whether it’s in shadow or sunlight, even though the amount of light hitting it changes.

Question 83

8C Visual Perception - Psychological Factors

Define Perceptual Set:

Answer 83

Perceptual set refers to a cognitive predisposition to perceive things in a particular way, influenced by:
1. expectations
2. prior knowledge
3. emotions
4. cultural background.

It acts as a mental filter that guides our interpretation of sensory information, often leading us to see or hear what we expect rather than what is actually present.

Question 84

8C Visual Perception - Psychological Factors

Define Expectations:

(In relation to Perceptual Sets)

Answer 84

Expectations refer to the anticipations or beliefs about what we are likely to encounter.

Expectations strongly influence how we perceive stimuli.

For instance, if you expect to see a friend in a crowd, you might mistake a stranger for your friend due to superficial similarities.

Question 85

8C Visual Perception - Psychological Factors

Define Context:

(In relation to Perceptual Sets)

Answer 85

Context refers to our preconceived ideas or beliefs in which we encounter stimuli that can shape our perception.

For example, imagine you’re walking alone at night in a quiet neighbourhood and suddenly hear a rustling noise behind you, you interpret the rustling noise as something threatening, like a person or animal
Where as if this happened at daytime in a Busy Park, you interpret the rustling noise as something curious, like a bird

Question 86

8C Visual Perception - Psychological Factors

Define Past Experiences:

(In relation to Perceptual Sets)

Answer 86

Past Experiences refers to previous experiences that can prime us to perceive things in certain ways.

For example, if you’ve had negative experiences with a particular type of food, you might perceive its taste more negatively in the future, even if it has been prepared differently

Question 87

8C Visual Perception - Psychological Factors

Define Emotion:

(In relation to Perceptual Sets)

Answer 87

Emotionrefers to our emotional state and how it can colour our perceptions.

For example, a person who is feeling anxious may perceive neutral faces as hostile or threatening, while someone in a positive mood might perceive the same faces as friendly

Question 88

8C Visual Perception - Psychological Factors

Define Culture:

(In relation to Perceptual Sets)

Answer 88

Culture refers to how different cultures emphasize different aspects of the environment and have varying experiences that influence perceptual expectations.

For example, in western societies a smile is an expression of being friendly, in some eastern societies a smile masks discomfort not being friendly

Question 89

8C Visual Perception - Psychological Factors

How does Perceptual Set work?

Answer 89

Perceptual set operates through top-down processing, where our brain uses existing knowledge, expectations, and experiences to interpret sensory information. Instead of just processing raw sensory data (bottom-up processing), our brain actively constructs our perception based on what we expect or are primed to see

For example, if you see a sequence of images related to animals and then are shown an ambiguous image that could be interpreted as either an animal or a human face, you are more likely to perceive the image as an animal due to the influence of the previous images​

Question 90

8C Visual Perception - Psychological Factors

Why is Perceptual Set important?

Answer 90

Perceptual set plays a crucial role in everyday life because it helps us make sense of the world quickly and efficiently. By relying on our expectations and prior knowledge, we can process information faster and make decisions based on limited sensory input.

However, this can also lead to biases and errors in perception, as we might overlook important details or misinterpret stimuli

Question 91

8C Visual Perception - Social Factors

Define Social Factors in Visual Perception

Answer 91

Social factors refer to external factors relating to an individual’s interactions with others and their external environment, including their relationships and community involvement. (Cultural Norms)

(Cultural Norms)

Question 92

8C Visual Perception - Social Factors

How do Cultural Norms relate to Visual Perception?

Answer 92

Our cultural background can shape our perceptual set, predisposing us to perceive visual stimuli in certain ways specific to our cultural context.

Cultural norms frame our way of viewing the world. This relates to top-down processing and our perceptual set.

For example, different cultures have different responses to that question and this relates to cultural perception.​

American children tended to group objects together because they belong to the same category e.g. animals (cow and chicken).​

Chinese children tended to group objects together based on relationships e.g. cow and grass because cows eat grass (Chiu, 1971).​

Question 93

8C Visual Perception - Social Factors

Question 96

8D Gastatory Perception

Where are gustatory receptors found in the body?

Biological Factors

Answer 96

Gustatory receptors are primarily found on the taste buds, which are located on the papillae of the tongue.

Question 97

8D Gastatory Perception

What is Gustatory Perception?

Biological Factors

Answer 97

Gustatory perception refers to the sensory experience of tasting, involving the detection of flavor through the tongue’s taste buds and the brain’s interpretation of these signals. This process includes detecting sweet, sour, salty, bitter, and umami flavors. Gustatory perception also involves how psychological and social factors influence our experience of taste.

Question 98

8D Gastatory Perception

Where are gustatory receptors found in the body?

Biological Factors

Answer 98

Gustatory receptors are primarily found on the taste buds, which are located on the papillae of the tongue.

Question 99

8D Gastatory Perception

What happens to our taste buds as we age?

Biological Factors

Answer 99

As we age, the number of taste buds decreases, and the remaining taste buds become less sensitive, reducing our ability to taste flavors.

Question 100

8D Gastatory Perception

what social factors influence Gustatory Perception?

Biological Factors

Answer 100

Social factors that influence gustatory perception include:

1. Cultural Influences: Cultural background can shape taste preferences and attitudes toward certain foods.
2. Social Norms: Eating habits and preferences can be influenced by social trends and the eating behaviors of peers and family.
3. Social Context: The environment in which food is consumed (e.g., formal vs. informal settings) and the presence of others can affect taste perception and enjoyment.

Question 101

8D Gastatory Perception

what biological factors influence Gustatory Perception?

Answer 101

Biological factors that influence gustatory perception include:

1. Taste Buds: The number and distribution of taste buds on the tongue can affect sensitivity to different tastes.
2. Age and Genetics: Taste sensitivity can vary with age and genetic differences, such as variations in taste receptor genes.
3. Health Conditions: Conditions like infections or neurological disorders can impact taste perception.

Question 102

8D Gastatory Perception

what psychological factors influence Gustatory Perception?

2. Emotional State: Mood can affect taste perception; for example, stress or happiness can enhance or diminish the taste experience.
3. Previous Experiences: Past experiences with certain foods can shape taste preferences and perceptions.

Question 103

8D Gastatory Perception

Can genetic factors influence food preferences beyond just sensitivity to flavors?

Biological Factors

Answer 103

Yes, genetic factors can also determine specific food preferences, such as whether someone likes or dislikes coriander

Question 104

8D Gastatory Perception

Give an example of how age-related changes in taste perception might influence an older adult’s diet.

Biological Factors

Answer 104

An older adult might prefer stronger-flavored or more seasoned foods because their reduced taste sensitivity makes milder foods taste bland.

Question 105

8D Gastatory Perception

How might being a supertaster affect a person’s food choices?

Biological Factors

Answer 105

A supertaster might avoid very bitter or overly sweet foods because they experience these flavors more intensely, making them less enjoyable.

Question 106

8D Gastatory Perception

Why might non-tasters be more willing to try a variety of foods?

Biological Factors

Answer 106

Non-tasters experience flavors less intensely, so they might be less likely to find certain foods overwhelming or unpleasant, making them more open to trying different foods.

Question 107

9A Errors of sight

What are Errors of sight related to?

Answer 107

Errors of sight are related to:
1. the fallibility of visual perception
2. visual illusions
3. the disorder Agnosia (9C)

Question 108

9A Errors of Sight

Define the Fallibility of Visual Perception:

Answer 108

Fallibility refers to the quality of being prone to error or experiencing difficulties in judgement.

The fallibility of visual perception is not due to errors in sensation (our ability to detect sensory information) but due to errors in perception (made within our brains in processing this information).

E.g. seeing an object in the distance that you realise isn’t really there as you get closer to it.

(This relates to perceptual distortions)

Question 109

9A Errors of sight

Define perceptual Distortions:

(Fallibility of Visual Perception)

Answer 109

Perceptual distortions refer to errors in the judgement or interpretation of sensory stimuli.

Question 110

9A Errors of sight

Define Visual Illusions:

Answer 110

A visual illusion is the perception of a visual stimulus that conflicts with how it is in physical reality.

Something in our physical external environment might make an image difficult to interpret during perception.

Question 111

9A Errors of sight

What factors are Visual Illusions caused by?

Answer 111

These illusions are often caused by biopsychosocial factors.

Meaning:
1. Biological factors - Something physiological might make an image difficult to interpret. E.g. looking at a bright light and still seeing that bright light even after turning the light off.
2. Social factors
3. Psychological factors - Something psychological. E.g. perceiving things in particular ways due to our own biases.

Question 112

9A Errors of sight

Define the Muller-Lyer Illusion:

(2 lines with different arror heads on each end)

Answer 112

The Muller-Lyer Illusion refers to a visual illusion where two equal-length lines appear different in length due to arrow-like figures at their ends.

• Outward Arrows: Lines seem longer, as if extending toward us.
• Inward Arrows: Lines seem shorter, as if extending away from us.

Question 113

9A Errors of sight

What psychological factors does the Muller-Lyer Illusion Encompass

Answer 113

1. Psychological Factors
   * include the Carpentered world hypothesis refering to how our experience with 3D environments affects our 2D perception.
2. Environmental/Social Factors
   * Social and cultural backgrounds influence perception of such illusions.
   * city residents are more susceptible (likely to be affected by or to be influenced by Muller-Lyer) due to exposure to more straight lines and angles.

Question 114

9A Errors of sight

Defines the Ames Room Experiment:

Answer 114

This illusion occurs when a person views two objects in a special Ames Room through a peephole using only one eye.

The shape of these rooms have been constructed in specific ways to trick our visual perceptual systems.

Question 115

9A Errors of sight

Identify the Visual Cues represented in the Ames Room Experiment:

Answer 115

The Ames Room manipulates some of our depth cues and visual constancies.

1. Depth Cue:
   * Relative size—objects appear different sizes because we perceive the room as normal-sized when it’s actually distorted.
2. Visual Constancies:
   * Size Constancy: We can’t judge the true size of objects due to distorted distance.
   * Shape Constancy: The room appears rectangular, though it’s a trapezoid, affecting our perception of shape.

Question 116

9B Errors of Taste

Define the Fallibility of Gustatory Percpetion:

Answer 116

The errors of taste and gustatory perception includes being prone to error or experiencing difficulties in…

judgement looking closely at supertasters and being introduced to how miraculin works and how we judge flavours.

Question 117

9B Errors of Taste

Define Supertasters:

Answer 117

Supertasters are individuals who have a significantly higher number of taste buds and a lower threshold for taste stimuli.
This heightened sensitivity results in more intense taste experiences.
Unlike perceptual distortions, which are errors in interpreting sensory stimuli, the heightened taste perception of supertasters is a result of biological differences and is accurate.

Question 118

9B Errors of Taste

Define Miraculin:

Answer 118

Miraculin is a protein from the ‘miracle berry’ that alters taste perception by making sour foods taste sweet.

Question 119

9B Errors of Taste

How does exposure to miraculin effect an individual?

Answer 119

Exposure to miraculin causes sour foods to taste sweet by binding to sweet taste buds and activating them in an acidic environment.

Miraculin works specifically by altering taste perception in acidic conditions, rather than changing the actual flavor of the food.

Question 120

9B Errors of Taste

Define Judgement of Flavours:

Answer 120

Judgment of flavors refers to the process of interpreting and assessing the taste qualities of food based on sensory input.

This involves recognizing and categorizing tastes such as sweet, sour, salty, and bitter, and combining these perceptions to form an overall experience of flavor.

It includes the integration of taste, smell, and sometimes texture to evaluate and respond to what is being consumed.

Question 121

9B Errors of Taste

Define Perceptual Set:

Answer 121

A perceptual set refers to a predisposition to perceive certain sensory stimulus features and ignore other features of the stimulus deemed irrelevant.

Question 122

9B Errors of Taste

What can Perceptual Sets lead to?

Answer 122

Perceptual Sets can lead to perceptual distortions in the way we taste.

E.g. tasting something more or less intenselythan it actually is due tothe food’s appearance or packaging.

Question 123

9B Errors of Taste

How does colour intensity influence flavour judgment?

Answer 123

The intensity of a food’s color can lead to perceptual distortions in flavor judgment.

Often, food with a more intense color is perceived to have a stronger flavour, even if that’s not true. This perception is related to our perceptual set, where past experiences lead us to expect that brighter colors indicate more ripe or intensely flavored food.

Question 124

9B Errors of Taste

How does texture influence flavor judgment?

Answer 124

Texture impacts flavor intensity because it determines how much food reaches our taste receptors and how long it stays in the mouth.
Texture can also influence enjoyment based on expectations and past experiences with how a food should feel.

For example, creamier foods stay in the mouth longer, allowing for more taste.

Question 125

9C Perceptual Distortions

Define Perceptual:

Answer 125

Perceptual refers to the ability to interpret or become aware of something through the senses.

Question 126

9C Perceptual Distortions

Define Distortions:

Answer 126

Distortions refers to a change to the intended or true meaning of something.

Question 127

9C Perceptual Distortions

Define Agnosia:

Answer 127

Agnosia refers to a disorder involving the loss or impairment of the abilitytorecognisefamiliar stimulithrough the use ofone or moresenses, despite the senses functioning normally otherwise.

In other words,people withagnosiaexperiencedifficultyidentifying sensory information, such as objects in theirenvironment.
This often occurs as the resultof a brain lesion.

E.g.visual agnosiais commonly associatedwith lesions in areas of the brain thatareresponsible for processing visual information.

Question 128

9C Perceptual Distortions

Identify the types of Visual Agnosia:

Answer 128

1. Associative Visual Agnosia
2. Apperceptive Visual Agnosia

Question 129

9C Perceptual Distortions

Define Associative Visual Agnosia:

Answer 129

Associative visual agnosia is a condition where an individual has difficulty identifying what an object is despite having normal visual perception and being able to recognize its individual visual elements.

The main issue is the inability to link prior experiences or knowledge to the object they are viewing.

(not malfunctioning just an error)

Question 130

9C Perceptual Distortions

Define Apperceptive Visual Agnosia:

Answer 130

Apperceptive visual agnosia is a condition where an individual has difficulty perceiving visual information despite having an intact mental understanding of what objects look like.
They struggle to identify objects even though their vision is otherwise functioning normally.

(not malfunctioning just an error)

Question 131

9C Perceptual Distortions

Define Synaesthesia:

Answer 131

Synaesthesia refers to a perceptual phenomenon where activation of one sensory system leads to unusual perceptions in another sensory system, such as seeing colors when hearing specific sounds (e.g., seeing green when hearing an F#).

Question 132

9C Perceptual Distortions

Identify Characteristics of Synaesthesia:

Answer 132

Characteristics of synaesthesia include:

1. Automatic: Cannot be controlled.
2. One-way process: Typically, the crossover is one-directional (e.g., seeing purple when looking at the number 8, but not the other way around).
3. Consistent: The experience is usually stable over time.
4. Unique: Varies from person to person.

Question 133

9C Perceptual Distortions

Identify and explain key types of Synaesthesia:

Answer 133

1. Grapheme-colour: occurs when a person sees colours when looking at ordinary symbols such as numbers and letters.
2. Sound-colour: occurs when sounds cause the secondary perception of colours e.g. seeing red when hearing a car horn.
3. Lexical-gustatory: when seeing a certain word causes a taste to betriggered e.g. tastinggarlic when reading the word’train’.

Question 134

9C Perceptual Distortions

Define Spatial Neglect:

Answer 134

Spatial neglect is an inability to perceive, report, or orient sensory information located within one side of space.
E.g. only perceiving sensory informationfrom either theleft or right side of the environment.

Question 135

9C Perceptual Distortions

What is spatial neglect?

Answer 135

Spatial neglect is a condition where individuals have difficulty perceiving one side of space, despite having normal senses.

Question 136

9C Perceptual Distortions

How is spatial neglect related to brain lesions?

Answer 136

Spatial neglect is often caused by brain lesions.
The side of space affected depends on the location of the lesion: a lesion in the right hemisphere typically impacts the left field of vision, and vice versa.
This neglect occurs contralaterally, meaning the neglected side is opposite to the side of the brain with the lesion.

Question 137

9C Perceptual Distortions

Define Brain lesions:

Answer 137

Brain lesions are damaged areas of brain tissue caused by injury, disease, or stroke that disrupt normal brain function.
