Biological explanation:Gottesman & shield. Aim:to review research on genectic transmission of schyzophrenia.
Methodology:review of 3 adoption and 5 twin studies:schizophrenia. Participant: 210 monozygotic(identical) 319 Dizygotic(non-identical).-comparison od parents and sibling and adoptive parents and siblings.
1 of 7
Results of Biological explanation: all studies=increased incidence of schizo=biological relatives.-all twin studies higher concordance in monzygotic than dizygotic. -concordance rates=58%=monozygotic.12%=dizygotic twins.
Evaluation of Biological explanation: reductionist=only 1 explanation ignores cog+bio factors. -diificult to replicate.

Behavioural explanation:Watson+Raynor, classical conditoning. Litlle Alberts fear induction.
session 1=1st time bars struck=jump+fall forward. session 2=after 5 presenations=he reacted=crying+crawling away from rat. Evaluation:+can be repeated. -low in eco.validity in lab.-ethical issues=psychological harm.

Cognitive Explanation:Beck:certain themes appared in the depressed patients that did not appear in the non-depressed patients=low self esteem, self blame.
-depressed patients had sterotypical responses to situations=they feel hated. some patients felt unlovale, alone even when friendship was shown. Evaluation:-not representative only upper and middle class used.-treat,ment is effective such as therapy.

Definitions of dysfunctional behaviour:Rosenhan and Seligman's, Abnormal behaviour1.
Statistical infrequency:This simply defines abnormal behaviour as that which is statistically rare in the population. E.g. schizophrenia is suffered by less than approximately 1% of the total population.
5 of 7
Deviation from social norms:Social norms are rules or behaviours established by society. We learn from a very young age what is normal behaviour in particular situations. (e.g. people don't usually laugh when you tell them someone bad news).
Deviation from ideal mental health:Jahoda identified six areas related to ideal mental health, she argues that if people deviate from one or more of these areas then the individual may be at a risk of suffering from a mental disorder.
6 of 7
Evaluation:definition focuses on the positives i.e. on the mental health rather than mental illness; • Jahoda's definition may only be applicable in Western societies more specifically individualistic cultures than in collectivist cultures.
Failure to function adequately:distresses the person experiencing it – not being able to go out of the house is distressing for agoraphobics.• Obsessive compulsive disorder, where person cannot go out because of the rituals they need to undertake b4.
