Biological Explanations

Question 1

What is the AO3 peel for the genetic theory?

Answer 1

RTS about adopted children and schizophrenic parents

Question 2

P

(RTS)

Answer 2

RTS the genetic theory/role of genetics in the development of sz was done by a psychologist.

Question 3

E

Answer 3

155 adopted children who had biological mothers with sz was studied and it was found they had a concordance rate of 10%

Question 4

E

Answer 4

Compared to 1% in adopted children without schizophrenic parents.

Question 5

L

Answer 5

Therefore this supports the role of genetics as an exp of sz
BECAUSE the role of SLT couldnt have been a factor as the children were adopted

Question 6

what is the AO3 PEEL for neural correlates?

Answer 6

RTS - brain scans on schizophrenic twins with enlarged ventricles

Question 7

P

(RTS)

Answer 7

RTS the role of neural correlates as an exp for sz was done by a psychologist

Question 8

E

Answer 8

MRI scans were used to investigate the brain structure of MZ twins, one of them was schizophrenic

Question 9

E

Answer 9

it was found that the schizophrenic twin had enlarged ventricles

Question 10

L

Answer 10

this suggests enlarged ventricles do play a role in determining the likelihood of sz developing

Question 11

what are the three AO3 PEELS for the overall biological exp?

Answer 11

• scientific methods
• biological determinism
• prac apps

Question 12

P

(scientific methods)

Answer 12

strength - scientific methods

Question 13

E

Answer 13

coz theory is based on objective and empirical techniques like gene mapping

Question 14

E

Answer 14

and brain scans such as FMRI which are used to identify specific genes or areas of the brain linked to sz

Question 15

L

Answer 15

-therefore this increases int val of the bio exp of sz, raising psychologys scientific status

Question 16

P

(biological determinism)

Answer 16

weakness - biological determinism

Question 17

E

Answer 17

coz theory states an indv is controlled by int. factors such as high dopamine activity in the subcortex which causes auditory hallucinations (hyperdopaminergia)

Question 18

E

Answer 18

this neglects the role of free will and choice indv have, this could make victims feel like they have no control over their sz bhv

STRETCH: unethical - families could feel guilt of passing one a gene that’s affected their children and they cant help

Question 19

L

Answer 19

therefore this limits the bio exp of sz

Question 20

P

(prac apps)

Answer 20

strength - prac apps

Question 21

E

Answer 21

coz POT, that sz is causes by an imbalance of dopamine has led to drug therapy treatment of typical and atypical antipsychotics

Question 22

E

Answer 22

these drugs are effective in treating sz by balancing levels of dopamine in the patients brain, reducing symptoms of sz such as hallucinations and delusions

Question 23

L

Answer 23

therefore the bio exp of sz i.a.i.p.o.a.p as it helps to treat ppl in the real world
