Flashcards in Cross Cultural Studies - Perception Deck (14):
1

What do cultural differences and similarities show?

Differences = learnt not innate
Similarities = evolutionary - innate

2

What might cultural differences be due to?

Biological factors e.g genetics + diet, or ecological factors such as local environment, cultural history and education

3

What did Turnbull do?

Studied the Bambuti Pygmies who lived in dense forest so had no size constancy as had no experience of looking at objects far away.
- One member taken out of the forest and saw a buffalo grazing in the distance

4

What did Turnbull find?

Thought the buffalo in the distance was an insect

5

What did Turnbull conclude?

His study supports cultural differences which supports Gregory - perception is learnt

6

How does SSNR relate to Turnbull's study?

- Unethical to expose members to outside world (bringing in Western technology e.g. a car), cause members to seek a different life

7

How does N/N relate to Turnbull's study?

- How would the tribe carry out everyday activities, such as hunting, without size constancy = could be a poor visual problem causing incorrect identification

8

How does PAS relate to Turnbull's study?

Only one member used, not reliable only valid

9

What did Hudson do?

Analysed how people responded to questions about pictures which included depth cues, such as relative size and overlap
- Asked what the objects were to ensure they were familiar with the relative size of the animals
- Then asked 'What is the man doing?' and 'which animal is closest to the man?'

10

What did Hudson find?

Non-Western people = difficulty seeing depth in picture, believed elephant was closer + that the man was hunting a small elephant - perceived as 2D rather than 3D

11

How does Hudson's study support nurture?

Shows cultural differences

12

How does PAS relate to Hudson's study?

1) Ambiguous Qs - example of cultural bias as Qs may be interpreted different in different cultures = may not think i terms of real life
2) Only 2 depth cues - if others were added African Ps more likely to interpret the picture in 3D

13

What happened when texture gradient was added to Hudson's study?

There was a much higher rate of perceiving depth - 64% 3D answers compared to 54% in Hudson' study
- When colour added = 73%

14

What did Eysenck and Keene show?

Showed that if the Muller-Lyer fins are replaced by circles we still fall for the illusions = CU as doesn't resemble the 'carpentered world' - innate
