1
Q

Outline the conclusion of Gilchrist and Nesbergs motivation study

A

Gilchrist and Nesburg suggested that participants who we’re hungry had perceived the images of the food brighter than those who were not hungry. This is because they were more motivated to have the food which made the image brighter and more appealing in their heads.

Q

Describe any ethical issues in Gilchrist & Nesberg’s motivation study

A

Physiological and physiological harm from the discomfort of not eating for 20 hours + deception as they thought they were doing a picture matching exercise

Q

Give an example of an extraneous variable that could have affected the results in Gilchrist & Nesburg’s motivation study

A

Participants eyesight- regardless of whether they were starved or not, some participants may have had difficulty readjusting the brightness of the projector if they just had poor eyesight to begin with

Q

Outline one strength of Gilchrist & Nesburg’s motivation study

A

Use of independent groups meant that participants could not see the other condition, which prevented them from guessing the true aim of the study, reducing demand characteristics

Q

Outline one weakness of Gilchrist &Nesburg’s motivation study

Q

Outline the method of Bruner & Minturn’s expectation study

A

24 participants were shown the ambiguous figure of “13” in either a number sequence “121314”, or a letters sequence “A13C”. The participants then had to say & draw what they had seen .

Q

Outline the results of Bruner & Minturn’s expectation study

A

Participants in the letters condition reported seeing “B” whereas the participants in the numbers condition reported seeing “13”. Participants were also more likely to draw the same figure in their own handwriting afterwards

18
Q

Give an example of an extraneous variable that could have affected the results in Bruner & Minturn’s expectation study

A

Participants eyesight- regardless of which sequence the participants saw, they could say/write down the wrong thing if they can’t see their sequence properly

19
Q

Outline the strength of Bruner & Minturn’s expectation study

A

Highly controlled lan experiment by controlling how long they saw their sequence for // use of independent groups so they couldn’t see the same figure being used in 2 different sequences

20
Q

Outline the weakness of Bruner & Minturn’s expectation study

A

Artificial task. ‘13’ was specifically designed to trick people - such tricks are not usually seen in mathematics or literature in the real world. Low external validity.

21
Q

Name the 2 named studies in the perception topic

A

Gilchrist & Nesburg and Bruner & Minturn’s

22
Q

What is sensation?

A

Sensation is the information we receive through our senses from the environment. It is the objective feeling of stimuli.

23
Q

What is perception?

A

Perception is the subjective interpretation and organization of sensory information by the brain. It is personal and based on past experiences.

24
Q

What is an example of perception affecting recognition?

A

Face Blindness is an example where people have the same sensations when looking at a face, but some cannot recognize the facial features due to perceptual difficulties.

Example: Face Blindness

25
What are visual cues?
Visual cues are aspects of our environment, such as movement, that give us clues about the spatial relationships between objects.
26
What are visual constancies?
Visual constancies are our ability to understand that an object remains the same, even if our visual sensation of it is slightly different.
27
What is the height in plane monocular depth cue?
Objects higher in the visual field are perceived as being further away.
28
What is the relative size monocular depth cue?
When objects you know are the same size appear different, the smaller one is perceived as being further away.
29
What is linear perspective in monocular depth cues?
Parallel lines appear to converge the further you look out.
30
What is size constancy?
Size constancy is the understanding that when an object moves closer, it does not actually get bigger; it is just moving towards us.
31
What is misinterpreted depth cues?
Misinterpreted depth cues occur when we perceive distance that is not actually there, causing us to incorrectly scale objects. ## Footnote Link to illusions: Ponzo Illusion, Müller-Lyer Illusion
32
What is ambiguity in perception?
Ambiguity occurs when there are two or more interpretations of a figure, and we can only focus on one at a time. ## Footnote Link to illusions: Necker Cube, Rubin's Vase
33
What is occlusion in binocular depth cues?
Occlusion is when objects that are behind or blocked by other objects are perceived as being further away.
34
What is retinal disparity?
Retinal disparity is the difference between the images seen by our two eyes, which helps perceive depth.
35
What is convergence in binocular depth cues?
Convergence occurs when our eyes come together to focus on an object that is near, indicating depth.
36
What is perceptual set?
Perceptual set is a tendency to notice or prefer certain aspects of the sensory environment while ignoring others.
37
How does culture affect perception?
Culture affects perception as our brains become specialized in processing information we experience the most, influenced by our upbringing.
38
How does emotion influence perception?
Emotion can lead us to perceive ambiguous situations in alignment with our current mood, often causing us to take longer to perceive unpleasant things.
39
What did Gilchrist & Nesberg's study find about motivation?
Participants who were starved for 20 hours adjusted the brightness of a food image to be brighter than those who ate normally, indicating they perceived it as more appealing. ## Footnote Named Studies!
40
What did Bruner & Mintum's study find about expectation?
Participants were more likely to report seeing an ambiguous figure in a way that made sense with their number/letter sequence, showing the influence of expectation. ## Footnote Named Studies!
41
What is Gregory's Constructivist Theory of Perception?
Gregory's theory suggests that perception is influenced by past experiences and is an active process, where we fill in gaps based on visual cues.
42
What is Gibson's Direct Theory of Perception?
Gibson's theory posits that perception abilities are innate and that sensation is perception, relying on sufficient information from the optic array.
