Outline and evaluate the biological approach to psychopathology
The biological approach to psychopathology suggests that abnormal behaviour is caused or related to physical changes in the body. The biological approach suggest that the four following things cause physical disorders (abnormality) ; genes, biochemistry, neuroanatomy and viral infection.
Psychologists have investigated the role in which gene’s play in abnormal behaviour. To do this the majority of psychologists use twins. It has been demonstrated that first-degree relative of a person suffering schizophrenia have a 10% chance of developing the disorder. This is much greater than the 1% in the normal population. Gottesman used a meta-analysis of about 40 twin studies and found that the concordance rate for schizophrenia was 48% in monozygotic twins however only 17% in dizygotic twins which proves that some abnormal behaviours are genetically inherited.
The biological approach suggests that abnormality is caused by neuroanatomy for example neurotransmitters can lead to disorders such as depression due to too little serotonin and anxiety due to little noradrenaline also too much dopamine can lead to schizophrenia. Another factor of the biological approach is viral infection. Its emphasized that viral infections can lead to disorders and abnormality for example the syphilis bacteria can cause sexually transmitted diseases which can cause general paresis, brain damage, forgetfulness, mental deterioration and delusions – these behaviours would be deemed as abnormal. Some forms of infections can rise into types of mental illnesses for example the influenza virus in pregnant women can often lead to schizophrenia.
A strength of this biological approach to psychology is that it requires a great amount of objective date resulting in findings being very specific with accurate scientific measures however one limitation of the biological approach is that it ignores all other approaches and definitions such as the

    The biological approach to psychopathology states that abnormal behaviour is a result of the brain not functioning correctly. This approach treats psychological disorders in the same way as physical orders. It suggests 4 main causes of abnormality: brain injury, infection, neurotransmitters and genetics.…

    The biological model compares abnormal behaviour with a disease. It assumes that all mental illnesses have a physiological cause related to the physical structure and brain. Doctors diagnose mental illness using well-established criteria. Psychiatrists also use diagnostic manuals for mental illness and compare symptoms with set classifications of illnesses. According to the biological model, mental illness is caused by one or more of the following factors; genetic inheritance, bio-chemistry and infection. The reason why genetic inheritance could be a possible cause for mental illness is due to the assumption that people have a genetic disposition to certain psychological disorders. For example, Kendler et al found relatives of schizophrenics were 18 times more likely to develop the illness than a matched control group. Bio-chemistry is also a factor that is considered as it is thought that chemical imbalances in the brain may be involved in certain mental illnesses. Neurotransmitters play an important part in behaviour. For example, an excess of dopamine has been detected in the brains of schizophrenics. This finding, however, has been assumed due to correlation which does not prove cause and effect. Infection is also thought to be a factor which could potentially cause mental illness as research suggests that some mental illnesses, such as schizophrenia, may be related to exposure to certain viruses in the womb. For example, Torrey found that the mothers of many people with schizophrenia had contracted a particular strain of influenza during pregnancy. It is supposed that the virus may have entered the unborn child’s brain and remained dormant there until puberty, when other hormones may have activated it.…

    in the womb). For example, Torrey (2001) found that the mothers of many people with schizophrenia had contracted a particular strain of influenza during pregnancy. The virus may enter the unborn child’s brain, where it remains dormant until puberty, when other hormones may activate it, producing the symptoms of schizophrenia. The emergence of the medical model in the 18th century led to more humane treatment for mental patients. Until then mental illness was blamed on demons or on evil in the individual. The medical model offered a different source of blame – the illness, which was potentially treatable. However, more recent critics have claimed that the medical model is inhumane. Thomas Szasz (1972) argued that mental illnesses did not have a physical basis, therefore should not be thought of in the same way. He suggested that the concept of mental illness was ‘invented’ as a form of social control. The available evidence does not support a simple cause and effect link between mental illnesses such as schizophrenia and altered brain chemistry. For example, schizophrenia is commonly associated with an excess of the brain neurotransmitter dopamine. However, some studies of schizophrenic patients have shown reduced levels of dopamine in some brain tissues, meaning that there may be simultaneous excesses and deficiencies in different parts of the brain. There is no evidence that mental disorders are purely caused by genetic inheritance – concordance rates are never 100%. Gottersman and Shields (1976) reviewed the results of five studies of twins looking for concordance rates for schizophrenia. They found that in monozygotic twins (identical) there was a concordance rate of around 50%. If schizophrenia was entirely the product of genetic inheritance then this figure should be 100%. It is likely that, in the case of certain disorders, what individuals inherit is…

    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 way.…

    Humans go through different developmental stages in their lifespan. As is stage occurs, an individual’s development becomes more mature. Through the four stages (infancy, childhood, adolescence, and adulthood) there are certain elements in which the individual has to master before mentally moving on to the next stage. If something abnormal happens during one of the stages the likely outcome is mental disorders such as psychosis or schizophrenia. There are biological, cognitive, and behavioral component the confusing disorders. Society has been disillusioned and undereducated by what schizophrenia actually is and how it can be treated.…

    The first explanation for schizophrenia is genetic factor. Researchers have done many studies in different kind of ways in order to study genetic inheritability disorder, such as schizophrenia. The studies include family studies, twin studies and adoption studies. Family studies would investigate individuals who have schizophrenia and determine if their biological relatives are also affected more often than non-biological relatives. The most famous schizophrenic’s family study was conducted by Gottesman, 1991. They found that schizophrenia is more common among biological relatives, also the closer the degree of genetic relatedness, the greater the risk of getting schizophrenia. For example, the concordance rate of children with two schizophrenic parents is 46%, whereas the concordance rate of children of one schizophrenic parent is 13%. Twin studies give an opportunity for researchers to investigate the contribution of genetic and environmental influences. Joseph 2004 has calculated that the concordance rate for monozygotic twins, who come from the same egg of biological mother, is 40.4%, whereas the concordance rate for dizygotic twins is only 7.4%. These suggest that the greater the similarity is because of genetic factors. Adoption studies help to avoid the problem of mixing genetic and environmental influences together. The most methodological sound adoption study to date was conducted by Tienari et al. 2000. They found that 11 out…
