perception studies & evals

Question 1

What was the evaluation of Gregory’s study

Answer 1

Ons strength is that there is support from research in different cultures as people interpret visual cues differently

One weakness is that Greogry used 2D Visual illusions-s which are artificial so the theory may not apply to real world situations

One weakness is that babies have some perceptual ability so perception can’t be just the result of upbringing

Question 2

What was the evaluation of Gibson’s study

Answer 2

One strength was Research was on 2nd WW pilots, so its relevant to daily life

One weakness is Perception is seen as accurate but illusions trick the brain, so theory is incomplete

One strenght was Gibson and walk showed few infants crawl off a visual cliff, so are born with depth perception.

Question 3

What was the aim of Hudson’s study

Answer 3

To see if different cultures perceive depth cues in 2D images differently

Question 4

What was the method of Hudson’s study

Answer 4

Method-Showed an image of a man hunting either an antelope or elephant. The elephant was in the distance but the unschooled children without the developed depth cues thought it was the elephant while the schooled children had the depth cues and saw the antelope being hunted

Question 5

What was the results of Hudson’s study

Answer 5

Results-The schooled participants were more likely to perceive the depth than the unschooled participants.

Question 6

What was the conclusion of Hudson’s study

Answer 6

Different cultures use depth cues differently

Question 7

What was the evaluation on Hudson’s culture study?

Answer 7

One weakness is that it is Cross-cultural research so Language differences could have made method used unclear so validity is affected

One weakness is the way the pictures were represented on paper may have confused participants affecting findings.

A further weakness is that the early cross-cultural studies were poorly designed causing findings to lack validity.

Question 8

What was the aim of McGinnis’ study

Answer 8

To know if anxiety provoking things are noticed more than neutral things

Question 9

What was the method of McGinnis’ study

Answer 9

Students were shown neutral and taboo words. They had to say the word out loud and their emotional arousal was measured through GSR.

Question 10

What was the results of McGinnis’ study

Answer 10

The taboo words took longer to say and they had a higher change in GSR.

Question 11

What was the conclusion of McGinnis’ study

Answer 11

Conclusion-Emotion affects perceptual sets, in this case perceptual defence.

Question 12

What was the evaluation on McGinnie’s emotion study?

Answer 12

One strength is that the form of measurment, GSR is a scientific method to measure emotion,better than rating scales
One weakness is that the Delayed recognition may just be embarrassment not perceptual defence.
One weakness is that It’s difficult to draw conclusions from research that is inconsistent

Question 13

What was the aim of Gilchrist and Nesberg’s study?

Answer 13

To find out if food deprivation affects perception of food

Question 14

What was the method of Gilchrist and Nesberg’s study?

Answer 14

Hungry (no food for 20 hours) and not hungry participants were shown a slide of a meal. Had to adjust light to level of a slide shown

Question 15

What was the results of Gilchrist and Nesberg’s study?

Answer 15

Participants perceived food as brighter the longer they were deprived of food

Question 16

What was the conclusion of Gilchrist and Nesberg’s study?

Answer 16

Sensitivity greater when food is deprived and hunger is a motivating factor

Question 17

What was the evaluation on Gilchrist and Nesberg’s motivation study?

Answer 17

A strength is that Sanford’s study found similar results which strengthens the validity of the conclusions
One weakenss is that Depriving people of food causes discomfort and a case of physical harm
One weakness is Participants judged pictures of food not the actual food

Question 18

What was the aim of Bruner and Minturn’s study?

Answer 18

To find out if an ambiguous figure is seen differently if context is changed

Question 19

What was the Method of Bruner and Minturn’s study?

Answer 19

Participants were shown a sequence of letters or numbers with an ambiguous figure in the middle.

Question 20

What was the results of Bruner and Minturn’s study?

Answer 20

Those who saw letters said B those who saw numbers said 13

Question 21

What was the conclusion of Bruner and Minturn’s study?

Answer 21

Shows that expectation is affected by the context the figure is presented

Question 22

What was the evaluation on Bruner and Minturn’s expectation study?

Answer 22

One weakness is Ambiguous figures are designed to trick perception so task lacks validity
A further weakness is Participant variable may have caused the difference in results not expectation
One strength is the study explains the serious mistakes people sometimes make in the real world.
