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

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 and evaluate the biological approach to abnormality? The biological or medical approach regards abnormality as illness or disease. Mental illness is thought to be related to the physical structure and functioning of the brain. There are four possible causal factors of abnormality: brain damage‚ infection‚ biochemistry and genes. The first factor is brain damage. Abnormal behaviour may occur if the structure of the brain is damaged in some way. Once disease or brain damage has caused mental

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 biological approach to abnormality The biological approach sees abnormality as a physical illness and removes psychological blame and responsibility for the behaviour form the patients. Biochemistry; which is where abnormal functioning in the brain can be caused by abnormal levels of neurotransmitters and hormones. Neurotransmitters are the chemical messengers that allow neurones to communicate with one another at synapses. Hormones are chemical messengers that are secreted

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 model of abnormality (12 marks) The biological model of abnormality is the idea that all behaviour is rooted in underlying physical processes. The biological model of abnormality assumes that there is a physiological reason for psychological disorders. The disorders are considered an illness and supposedly make a person with these ’disorders’ abnormal. The model indicates that mental illnesses resemble physical illnesses and are thought to be treated in a similar
