Biological Explanations Flashcards
What is the AO3 peel for the genetic theory?
RTS about adopted children and schizophrenic parents
P
(RTS)
RTS the genetic theory/role of genetics in the development of sz was done by a psychologist.
E
155 adopted children who had biological mothers with sz was studied and it was found they had a concordance rate of 10%
E
Compared to 1% in adopted children without schizophrenic parents.
L
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
what is the AO3 PEEL for neural correlates?
RTS - brain scans on schizophrenic twins with enlarged ventricles
P
(RTS)
RTS the role of neural correlates as an exp for sz was done by a psychologist
E
MRI scans were used to investigate the brain structure of MZ twins, one of them was schizophrenic
E
it was found that the schizophrenic twin had enlarged ventricles
L
this suggests enlarged ventricles do play a role in determining the likelihood of sz developing
what are the three AO3 PEELS for the overall biological exp?
- scientific methods
- biological determinism
- prac apps
P
(scientific methods)
strength - scientific methods
E
coz theory is based on objective and empirical techniques like gene mapping
E
and brain scans such as FMRI which are used to identify specific genes or areas of the brain linked to sz
L
-therefore this increases int val of the bio exp of sz, raising psychologys scientific status
P
(biological determinism)
weakness - biological determinism
E
coz theory states an indv is controlled by int. factors such as high dopamine activity in the subcortex which causes auditory hallucinations (hyperdopaminergia)
E
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
L
therefore this limits the bio exp of sz
P
(prac apps)
strength - prac apps
E
coz POT, that sz is causes by an imbalance of dopamine has led to drug therapy treatment of typical and atypical antipsychotics
E
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
L
therefore the bio exp of sz i.a.i.p.o.a.p as it helps to treat ppl in the real world
