AO3 evaluation for neuroanatomical explanation

Question 1

what is a supporting evidance for the neuroanatomical explination

Answer 1

menzies et al

Question 2

what did menzies et al find

Answer 2

when conducting brainscans of OCD paintents found less grey matter in brain areas

Question 3

where didi menzies et al find less grey matter

Answer 3

in less brainareas including the orbitalfrontal cortex

Question 4

who was this compared to

Answer 4

healthy control group

Question 5

how does this support the neuroanatomical explanation of OCD

Answer 5

t/f suggests a physical differance in orbitalfrontalcortex in people with OCD supporting the neuroanatomical explination of OCD

Question 6

what is anouther supporting research

Answer 6

feng et al

Question 7

what animal did feng use

Answer 7

mice

Question 8

what did feng at al do

Answer 8

bred mice to show symptoms linked to OCD when a certain gene was missing.

Question 9

what was the missing gene in feng et al’s research

Answer 9

gene is one expressed in the brain areas associated with planning and initiation of actions, showing a clear link to the formulation of compulsions

Question 10

how does Feng et al’s research support the neuroanatomical explanation of OCD

Answer 10

t/f suggests dysfunction in certain areas of the brain can lead to OCD which the neuroanatomical explination explains

Question 11

how can fengs research be criticized.

Answer 11

its anthropermorphic

Question 12

how is fengs research anthropermorphic

Answer 12

fengs research only uses animals such as mice which have a completely different genome and barin structure to humans
t/f meaning we caanot generalise the findings of dysfuction in certin areas of the brain leading to OCD in mice to humans meaning the supporting research lacks validity decreasing the validity of the neuroanatomical expliantion of OCD

Question 13

what is anouther weakness of the neuroanatomical approach

Answer 13

cause and effect

Question 14

why cant cause and effect be established

Answer 14

becuse brainscans where conducted on paitents after they had been diagnosed with OCD we cannot be sure the changes in the brain cuased OCD or OCD caused changes in the brain

Question 15

how does the lack of cuase and effect oppose the neuroanatomical approach

Answer 15

t/f reducing the validity of the neuroanatomical approach to OCD as we cannot be sure cause and effect has been establishedso we cannot be sure OCD is due to a faulty neuroanatomical loop

Question 16

whats a supporting research strength

Answer 16

max et al

Question 17

what did max et al find

Answer 17

that when basal ganglia disconnected from frontal cortex during surgery OCD like symptoms are reduced

Question 18

what does this then suggest

Answer 18

t/f suggesting that the basal ganglia plays a role in OCD symptoms thus increasing the validity of the neuroanatomical explanation

Question 19

what is another non -resarch supporting evidence for neuroanatomical explanation

Answer 19

reliable and objective methods

Question 20

why is it being reliable and objective a strength

Answer 20

many studys use brain scand or PET scans to look at the brain of OCD paitents compared to a healthy control group. this is an objective scientific method of gathering data and can easliy be verified by anouther researcher as it is qualitative data

Question 21

how does this support the neuroanatomical explanation

Answer 21

t/f findings are reliable as they are objective and can be verified by different researchers increasing the validity of the neuroanatomical explanation of OCD

Question 22

what is another weakness - research based

Answer 22

sanematsu et al

Question 23

what did sanematsu et al find

Answer 23

found differances in other brain areas of OCD paitents compared to healthy controlsuch as parietal cortex and cerebellum

Question 24

how does sanematsu’s research oppose the neuroanatomical

Answer 24

t/f shows that that actual areas of the brain affected by OCD are not just those in the neuroanatomical explanation thus reducing it’s validity

Question 25

what is another weakness of the neuroanatomical explanation

Answer 25

reductionist

Question 26

how is the neuroanatomical explanation of OCD reductionist

Answer 26

only accounts for nature and not nurture factors in the environment such as social learning theory meaning it’s not a holistic explanation of OCD

Question 27

how does this oppose the neuroanatomical explanation of OCD

Answer 27

t/f reduces the validity of the theory as it isn’t holistic and only considers natures affect in explaining OCD
