Q

what is the sample in sperrys study

A

11 split brain patients with their corpus callosum severed
1 male had the surgery 5.5 years before the study
1 female had the surgery years before the study and the rest had the surgery shortly before

16
Q

what was the set up in the visual tests

A

patients sat in front of a projector screen with one eye covered
point in the middle of the screen that they had to focus on word or image would appear on the screen for 1/10th of a second
images presented with a tachistoscope

17
Q

what happened in the visual tests with the one image

A

if image displayed to right visual field they could say what they saw
if it went to left visual field they couldnt say what they say
matching object could be picked out from array with left hand because its linked to right hemisphere

18
Q

what happened when two images displayed at same time

A

when images displayed to left and right fields they could only say what they had seen in the right visual field
if asked to draw what they had seen using left hand they draw what was displayed to left visual field because its linked to right hemisphere
when a nude image was shown to left visual field they would giggle and blush but not be able to say why

19
Q

how were the tactile tests set up

A

participants sat in front of a screen with a gap underneath to put their hands through

20
Q

what happened in the tactile tests

A

if p`s originally picked up an object with their left hand they could not retrieve it with their right hand but could find it with their left hand
if they were holding an object in their left hand they could not say what they were holding however they could name the object they were holding in their right hand \

21
Q

what are the conclusions from sperrys study

A

provided evidence for lateralisation of brain function
however issues with sharing information between hemispheres is not a day to day issue in the real world as information in normally presented for more than 1/10th of a second

22
Q

What happened in the marshmallow test

A

children sat in room with marshmallow in front of them and were told if they waited till the researcher came back they could have two
Researcher left for 15 minutes and when he came back 2/3 had eaten the marshmallow

23
Q

What was the aim of caseys study

A

to investigate whether delay of gratification in childhood can predict delay of gratification in adulthood

24
Q

What was the original sample in caseys study

A

562 students from Stanford University nursery four years old
59 agreed to do first experiment

25
Q

Was was the sample from caseys second study

A

27 original participants
15 High
11 low

26
Q

How many trials per run

A

160

27
Q

How were trials presented to participants

A

pre programmed laptops sent to homes

28
Q

How long was stimuli shown for

A

0.5s

29
Q

What was the hot task

A

click when you see a happy face and not when you see a fearful face

30
Q

What was the cold task

A

click when you see a male face and not when you see a female face

31
Q

What was the results from the First experiment

A

no difference in reaction times
Both groups accurate on go no go tasks
Low delayers made more mistakes on hot than cool task

32
Q

Which system more active in High delayers

A

inferior frontal gyrus

33
Q

Which system more active in low delayers

A

ventral striatum

34
Q

What was the set up in thefMRi scanner

A

screen to display task and a neuroscan 5 pad button for ps to react to stimuli

35
Q

Which condition was completed in the scanner

A

only the hot one

36
Q

How long were the gaps between the pictures shown in the scanner

A

2 to 14.5 seconds

37
Q

What were the conclusions from caseys study

A

ability to delay gratification is a skill that is stable over a lifetime and has a biological cause
Also depends on stimuli

38
Q
A
