Answer 1

everything that is psychological is First physiological
Behaviour has a physical cause

What are the 3 causes of behaviour

Answer 2

the brain
Genes
Hormones

Question 3

What is a hormone

Answer 3

A chemical produced in glands

Question 4

What is the methodology of the biological area

Answer 4

Psychology should be studied as a science and use scientific processes eg brain scans

Question 5

What is brocas area responsible for

Answer 5

Speech production - worked with a man who could only say the word tan
autopsy showed damage to the left frontal lobe

Question 6

What is wernickes area responsible for

Answer 6

speech comprehension worked with patients whose speech was fluent but disordered autopsies showed damage to top of left hemisphere

Question 7

What did severing the corpus callosum do

Answer 7

Stop seizures from epilepsy

Question 8

What is the corpus callosum

Answer 8

A bundle of nerves that allows information to pass between the two hemispheres

Question 9

What does the left side of the brain Control

Answer 9

Perception
Planning
Language
The right side of the brain

Question 10

What does the right side of the brain Control

Answer 10

intuition
Creativity
Emotion
The left side of the body

Question 11

What is the inferior frontal gyrus

Answer 11

area in frontal lobe that is in both hemispheres
Interpretation of facial expression generates appropriate response
Known as cool system

Question 12

What does the ventral striatum do

Answer 12

area in the limbic system that is associated with Immediate choices and rewards
Responsible for behaviour and social interaction

Question 13

what is the aim of sperrys study

Answer 13

to investigate the functions of the hemispheres in the brain and the effects of deconnection in split brain patients

Question 14

what is the sample in sperrys study

Answer 14

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

Question 15

what were the 2 types of test in sperrys study

Answer 15

visual and tactile

Question 16

what was the set up in the visual tests

Answer 16

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

Question 17

what happened in the visual tests with the one image

Answer 17

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

Question 18

what happened when two images displayed at same time

Answer 18

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

Question 19

how were the tactile tests set up

Answer 19

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

Question 20

what happened in the tactile tests

Answer 20

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 \

Question 21

what are the conclusions from sperrys study

Answer 21

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

Question 22

What happened in the marshmallow test

Answer 22

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

Question 23

What was the aim of caseys study

Answer 23

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

Question 24

What was the original sample in caseys study

Answer 24

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

Question 25

Was was the sample from caseys second study

Answer 25

27 original participants
15 High
11 low

Question 26

How many trials per run

Answer 26

Question 28

How long was stimuli shown for

Answer 28

0.5s

Question 29

What was the hot task

Answer 29

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

Question 30

What was the cold task

Answer 30

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

Question 31

What was the results from the First experiment

Answer 31

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

Question 32

Which system more active in High delayers

Answer 32

inferior frontal gyrus

Question 33

Which system more active in low delayers

Answer 33

ventral striatum

Question 34

What was the set up in thefMRi scanner

Answer 34

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

Question 35

Which condition was completed in the scanner

Answer 35

only the hot one

Question 36

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

Answer 36

2 to 14.5 seconds

Question 37

What were the conclusions from caseys study

Answer 37

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