Question 1

What is the background to Sperry?

Answer 1

previous research using split brain animals show numerous behavioural effects.

Question 2

What is the research method for Sperry?

Answer 2

Considered to be a quasi/natural experiment because the IV (split brain or not) wasnt directly manipulated by the researches.

Question 3

What was the DV in sperry?

Answer 3

The participant’s ability to perform a variety of visual and tactile tests.

Question 4

What was the sample for Sperry?

Answer 4

11 patients who had undergone an extensive midline section of the cerebral commissures to prevent epilepsy.

Question 5

What was the test in sperry that looked at presenting visual information?

Answer 5

the participant has one eye covered and focuses gaze on a centered gaze on a fixed space on the screen. the time the image stayed on the screen was too fast for the information to get in the wrong visual field.

Question 6

What was in the test in sperry which was presenting tactile information?

Answer 6

Below the translucent screen there was a gap so participants could reach objects but not see there hands. objects placed in their right hand is processed by the left hemisphere and vice versa.

Question 7

What was the key findings for sperrys visual test?

Answer 7

Information shown and responded in one visual feild can only be recognised again if shown in the same visual field.

Question 8

What is a possible conclusion to Sperry?

Answer 8

People with split brains have two separate visual inner worlds.

Question 9

What is a theory of Casey?

Answer 9

The ability to resisit temptation in favour of long term goals is an essential component of an individuals economic success

Question 10

What is the research method for Casey?

Answer 10

considered a quasi/natural experiment

Question 11

What is the IV for Casey?

Answer 11

weather the participant was a low or high delayer

Question 12

What was the DV in Casey?

Answer 12

the performance on the impulse control task.

Question 13

How long did Caseys study last?

Answer 13

Longitudinal study which followed some participants from the age of 4 till they were 40.

Question 14

What was the original sample for Casey?

Answer 14

562 4 yr olds from stanfords bing nursery school. 59 participants took part when they were 40

Question 15

What was the outline of experiment 1?

Answer 15

go no go task.

Question 16

What did experiment 2 in Casey include?

Answer 16

FMRI was used to examine neural correlates of delay of gratification.

Question 17

What was the Key findings to Caseys experiment 1?

Answer 17

participants performed with a high level of accuracy for correctly responding to “go trials” during the cool and hot tasks

Question 18

What was the key findings in Caseys experiment 2?

Answer 18

The 2 delay groups did not differ significantly in reaction times in the correct go trials

Question 19

What is a possible conclusion to Casey?

Answer 19

Sensitivity to environmental hot cues plays a significant role in an individuals ability to suppress actions towards alluring cues.

Question 20

What is the background to Blakemore and cooper?

Answer 20

Question 21

What was the research method for Blakemore and Cooper?

Answer 21

Question 22

What was the Dv in Blakemore and Cooper?

Answer 22

The kittens behavior when placed in an illuminated environment

Question 22

What was the IV in Blakemore and Cooper?

Answer 22

Question 26

What was a possible conclusion for Blakemore and cooper?

Answer 26

Visual experiences in the early life of kittens can modify their brains and have profound perceptual consequences

Question 27

What is the background to Maguire?

Answer 27

Aimed to show the hippocampus in the human brain is the structure associated with spatial memory and navigation

Question 28

What was the research method for Maguire?

Answer 28
