According to the biological approach the mental disorder Schizophrenia will have an underlying physical cause such as imbalance of hormones‚ brain damage and infection. There is strong evidence that biological factors influence the presence of Schizophrenia. There are certain chemical abnormalities that can be observed in people suffering from schizophrenia. Post-mortems on schizophrenics have shown unusually high levels of dopamine. Dopamine is a brain chemical that increases the sensitivity of

Outline & evaluate the cognitive interview. (12 marks) The cognitive interview was devised by psychologists in order to eliminate the effects of misleading questions and misleading information. The process consists of first reporting everything the witness can remember‚ even information they believe to be unimportant.

In society there are social norms (standards of acceptable behaviour that are set by the social group). These standards are often in place for good reason. An example of a social norm is politeness as

Outline and evaluate biological explanations of obesity Various explanations can be provided for the reasons of obesity‚ from biological explanations‚ to neurological and evolutionary theories. Even socio-economic reasons could give insight into why some people have a higher likeliness of obesity Evolutionarily‚ the thrifty gene hypothesis provides insight as to why many suffer from obesity‚ as it suggests that our current genes are no longer suited to our new environment. Modern day society is

The biological approach can be useful to explain why Afina sometimes damages the school property by behaving in a deviant and antisocial manner. This approach assumes that there is a genetic predisposition which accounts for aggression and there is supporting evidence for this from research studying twins. For example‚ McGuffin and Gottesman (1985) found that 87% of identical twins shared aggression levels compared to only 60% of non-identical twins‚ supporting the basis of genes in the influence

The biological approach to psychology which looks at physical aspects controlling behaviour such as the structures of the brain‚ gives evidence that both nature and nurture are involved in our behaviour. For instance a study which compared the incidence of schizophrenia in MZ and DZ twins (Gottesman and Shields (1966)) found a concordance rate of 40% for the MZs but only 9% for the DZs. As arguably the only material differences between these groups was the fact that MZs share 100% genetic material

Outline and evaluate the cognitive approach to psychopathology The cognitive approach to psychopathology focuses on the theory that abnormality is caused by faulty cognitions about ourselves‚ others and our worlds. Our behaviour is controlled by these cognitions‚ consequently if these are faulty‚ it can cause abnormal behaviour. In 1962 Ellis proposed the A-B-C model. This suggests that a certain behaviour will first start with an activating event (such as seeing a large dog). This will then

Outline and evaluate the biological explanation of depression. Biological explanation of depression can be explained by neurotransmitter dysfunction. Neurotransmitters such as noradrenalin and serotonin have been shown to be linked with depression. Bunney at al (1965) found that there was low levels of noradrenaline function in the brain of depressed individuals. Also‚ post mortem studies found increased noradrenaline receptors in the brains of depressed suicide victims. When there is low noradrenaline

Outline and evaluate biological explanations for aggression (24) The biological explanation for aggression states that aggression is innate behavior in people and the environment around them does not cause it. Neurotransmitters in the brain‚ chemicals that allow impulses to be transmitted from one area to another‚ can be used to explain why some people are aggressive. There is evidence to suggest that the neurotransmitters serotonin and dopamine are linked to aggression‚ low levels of serotonin
