cognitive functions such as organising, control and planning. As well as voluntary movement and langauge.

Question 2

Answer 2

distance and depth perception, memory formation and face recognition

Question 3

what is the role of the temporal lobe?

Answer 3

auditory information and encoding memory

Question 4

what is the role of the frontal inferior gyrus?

Answer 4

processing of speech and language in brocas area

Question 5

what is the function of the corpus callosum?

Answer 5

ensures both sides of the brain can communicate and send signals to each other

Question 6

what is the role of the hippocampus?

Answer 6

major role in learning and memory and flight or fight reaction

Question 7

what is the role of the cerebellum?

Answer 7

making postural adjustments in order to maintain balance and sensory systems

Question 8

what is the role of the ventral striatum?

Answer 8

reward processing and desicion making

Question 9

what is the role of the parietal lobe?

Answer 9

language processing

Question 10

what is the role of the primary motor cortex?

Answer 10

makes muscles move

Question 11

what is the role of the Brocas area?

Answer 11

speech production (lips, jaw, tounge)

Question 12

what is the role of the wenikes area?

Answer 12

speech comprehension

Question 13

what is the aim of sperry’s study?

Answer 13

Sperry used split brain patients to show that each hemisphere: possess an independent stream of conscious awareness and has its own separate chain of memories that are inaccessible to the other

Question 14

what are the independent and dependent variables?

Answer 14

iv: having a split brain
dv: participants ability to perform a variety of visual and tactile tests

Question 15

what is the experimental method?

Answer 15

quasi experiment
or case study

Question 16

what is the design

Answer 16

repeated measures design

Question 17

what was the sampling technique?

Answer 17

opportunity sample

Question 18

what was the sample?

Answer 18

11 people
1st patient (male) had surgery over 5 and a half years before the study
2nd patient (female) had her surgery more than 4 years before the surgery
the other 9 patients had their surgery at varying times but not long before the study

Question 19

what does contralateral control mean?

Answer 19

movement of each side of the body is controlled by the opposite side of the brain

Question 20

what does localisation mean ?

Answer 20

certain functions take place in particular areas of the brain in both hemispheres

Question 21

what does lateralisation mean

Answer 21

certain functions take place in one hemisphere not both

Question 22

describe the visual tests

Answer 22

stimuli was presented to one visual field for 1\10th of a second too quick for eye movement and so information is presented to one hemisphere only .
P’s were then asked to identify the picture or word

Question 23

describe the tactile tests

Answer 23

an object is presented to either the right or left hand. however the participant cannot see what the object is .

Question 24

what are the controls of this study

Answer 24

1 eye is covered
the image is flashed for 1/10th of a second
board preventing the view

Question 25

explain what happens when the tactile stimuli is presented to different hands

Answer 25

objects put in the right hand can be described and named however participants can can only make wild guesses about objects placed in their left hand

Question 26

key theme question

Answer 26

who- 11 split brain patients
aim-to show each hemisphere possess an independent stream of conscious awareness and has its own seperate chain of memories
how- conducting tests by presenting visual and tactile information
findings-

Question 27

area question

Answer 27

assumption- different areas of the brain are responsible for different behaviours
aim
findings

Question 28

ethical considerations

Answer 28

protection from harm and consent

Question 29

what are some similarities between sperrys and caseys study

Answer 29

quasi experiments
repeated measures design
opportunity sample

Question 30

what are some differences between sperrys and caseys study

Answer 30

S-snapshot
C-longitudinal
