Depression may be expressed differently and may escape the attention of people from different cultures. Reported depression rose with westernization in colonial countries. Raine et al How does it reflect an experiment?

The SCN is located above the optic chiasm. The theory is also reductionist because it ignores the main role of nurture, however it does state that a predisposition is inherited allowing for the role of nature in the initiation of the illness.

In conclusion, the dopamine hypothesis is not entirely valid when looking at the causes of schizophrenia and is therefore reductionist. They all developed schizophrenia although the onset and symptoms were very different.

For example, due to ethical or financial restrictions. However, most first degree relatives and twins share the same or similar environments so it is difficult to separate genetic and environmental influences. These were compared with adopted children who did not had a schizophrenic mother.

Laboratory experiment because the study was conducted in a laboratory setting and the IV was manipulated Why was an experiment used Allowed a cause and effect relationship to be developed and recognised Cause: Evidence for the importance of expressed emotion has been found in studies across different cultures so there can be little doubt of its importance in explaining relapse.

Brown showed that patients who returned Discuss one or more biological and hospital to homes where there was a high level of emotionality High levels of Emotion were Expressed — HEE were more likely to have a relapse, and would have it sooner than those with LEE Low levels of Emotion Expressed families.

Therefore, this research provides some evidence for the double bind theory. Nurture needs to be considered and the evidence suggests environmental factors must play a part.

Another biological explanation is the dopamine hypothesis. This is reductionist as other approaches can draw different conclusions, which the biological approach fails to account for. However, studies investigating the role of EP that use animals, such as DeCoursey are highly unethical; this is because removing the SCN of the chipmunks would have caused them a considerable amount of pain and eventually resulted in death.

However with any retroactive study interpretability of findings is limited by the fact that recall may be unequally biased in the schizophrenic group. Tienari et al used Finnish adoptees whose biological mothers had been diagnosed with schizophrenia. These studies can also be criticized for imposed etic as researchers assume findings are relevant to humans as well as animals.

Cognitive etiologies of depression Learned helplessness and hopelessness Theorist: There is evidence which supports this hypothesis. Laboratory experiment because the study was conducted in a laboratory setting and the IV was manipulated Why was an experiment used Allowed a cause and effect relationship to be developed and recognised Cause: Homes where face-to-face interaction is characterised by intense emotional concern or criticism are less conducive to recovery than homes with more emotionally stable interactions.

Even when the adopted environments are similar there is still the shared experience in the womb and at birth so pre-natal viruses or birth trauma may have had an effect. First born and only children reporting more OC behaviors. Neurotransmission Patients with OCD responds positively to SSRI, suggesting that an imbalance of Serotonin maybe the cause of dysregulation of the neurological pathway.

Amount of testosterone being secreted Effect: He gave out a questionnaire containing 30 double bind statements and asked the participants to rate them on a 4 point scale in terms of how frequently they recalled their mothers using these type of statements.

He found that at first his sleep pattern was erratic, but settled then down to a regular pattern of hours.

When light hits the retina it transfers through the optic nerve to the SCN which stimulates the release of hormones such as cortisol and melatonin in the pineal gland. Supporting evidence for the dopamine hypothesis can be found by research by Wong et al who conducted PET scans on medication free schizophrenics, those taking phenothiazines and normal controls matched for age.

It is also culturally biased as it is not representative of other cultures and can be criticised for imposed etic in assuming the findings are applicable to all cultures.

The first biological explanation I will look at is the genetic theory of Schizophrenia. Rosenthal took a case study which had a set of female quadruplets.

It is not the amount of dopamine, but the sensitivity and density of dopamine receptors. These were compared with adopted children who did not had a schizophrenic mother.

Opinions and conclusions should be presented clearly and supported with appropriate evidence and sound argument. For example, Miles et al found that a man who was blind from birth had a circadian rhythm of Furthermore, the famous study of free-running biological rhythms in involving Michel Siffre supports the presence of EP in our sleep-wake cycle.

Once again suggesting it is reductionist. The evidence for the effect of other family members and their emotional responses on recovery from schizophrenia is now well established and the care package for schizophrenia recovery usually includes some education and support for other family members.

In humans, the main biological clock is the suprachiasmatic nucleus (SCN) which is located in the hypothalamus. This essay will attempt to offer a balanced review of how and why particular research methods are used at the biological level of analysis (BLA).
