Question 1

The dopamine hypothesis is supported by drug studies,

Answer 1

showing that drugs that increase dopamine activity cause hallucinations and delusions

Question 2

he genetic explanation of schizophrenia is supported

Answer 2

The genetic explanation of schizophrenia is supported by Gottesman and Shields’ twin study.

Question 3

The cognitive explanation is supported by O’Carroll’s review

Answer 3

The cognitive explanation is supported by O’Carroll’s review, which showed that 75% of schizophrenic patients had cognitive dysfunction.

Answer 5

inherited genetic risk alleles for schizophrenia from his mother

Question 6

Answer 6

Jumping to conclusions bias

Question 7

Biological and psychological explanations are differenent

Answer 7

Biological and psychological explanations are different levels of explanation. Of the two, biological explanations are more reductionist .

Question 8

The interactionist explanation of schizophrenia says that…

Answer 8

schizophrenia is caused by an interaction between biological factors and psychological factors.

Question 9

A person having a diathesis for schizophrenia means that…

Answer 9

Bthey carry biological risk factors that make them more likely to develop schizophrenia.

Question 10

When we looked at the diathesis-stress model in Issues & Debates, we saw that it was an example of…

Answer 10

Aa gene-environment interaction

Question 11

According to the diathesis-stress model…

Answer 11

Bpeople with a diathesis only develop schizophrenia if they experience enough psychological stress in their environment.

Dbiological factors act as a risk factor that gives people a diathesis for developing schizophrenia.

Ethe more stress people have, the more likely they are to develop schizophrenia.

Fthe more diathesis people have, the more likely they are to develop schizophrenia

Question 12

We’ve now seen support for the diathesis-stress model of schizophrenia:

Tienari et al conducted an adoption study comparing…

Answer 12

Adopted children who had biological mothers
Adapted children who did not have biological mothers with schizophrenia
The adopted ones with a biological mother more likely to develop schiphorzenia however were even more likely if the adopted family had conflict

Question 13

We’ve now seen further support for the interactionist explanation of schizophrenia, from a study which…
brown and barley

Answer 13

Dconducted interviews with patients who had recently developed schizophrenia

Efound that

50 % of the participants had a stressful life event in the three weeks prior to symptoms started

Awas conducted by Brown and Birley

Question 15

By themselves, antipsychotic drugs are bad at treating…

Answer 15

Adysfunctional mental processes

Cnegative symptoms

Question 16

Complete last summary

Answer 16

The interactionist approach to treating schizophrenia involves giving the patient a combination of treatments.

Patients are given antipsychotic medication to treat positive symptoms, and CBT or cognitive behavioural therapy to reduce dysfunctional mental processes and reduce the negative symptoms.

Finally, the patients and their families also go through family therapy to prevent relapse and help reduce the stressful family environment that triggered schizophrenia.

Question 17

Since it was a randomised, controlled study…

Answer 17

Ait had high internal validity

Cthe participant variables were controlled through random allocation

Eit had a control group

Fresearchers could use it to establish a cause and effect relationship

Question 18

If combining treatments prevents relapse and helps make people better, in the long run, it might still be worth it, because, if the treatments work…

Answer 18

Bpatients are less likely to return to hospital

Cpatients are more likely to return to work

Question 19

We’ve now seen some strengths and limitations of the interactionist approach to treatment.

Answer 19

A strength of this approach is that it is supported by a randomised controlled trial conducted by Guo et al, which showed that combining medication and therapy is more effective at treating schizophrenia than just using medication.



But, one limitation of this approach is that combining treatments is expensive
