Describe discuss the biological approach

A further objection to the biological approach could be that it tends to focus on genetic and biological influences on behaviour to the exclusion of social and cultural influences. The biological approach attempts to explain all behaviour through biology, particularly focusing on genetics, neurochemistry and hormonal changes as well as how evolution may have shaped human behaviour.

Could anyone help me by look over my essay for the biological approach and tell me whether I have written too much or too little and if I have included the right amount of AO1 and AO3. Furthermore, because the genes we inherit are the result of evolution, many biopsychologists think that behavioural and psychological characteristics may have evolutionary explanations.

Drug intervention can reduce or remove the effects of this disorder. Another strength of the biological approach is that it can make clearer predictions regarding behaviour and possible links it has to biology.

Other biopsychologists focus more on the role of genetic influences in particular types of behaviour. Various types of brain scanning technology including PET and MRI can be used to study the structure and functioning of the brain.

It was widely held by biopsychologists that criminal behavior was due largely to heredity and many were in favor of eugenics, a means, they thought, to improve the human species through compulsory sterilization of criminals, the mentally retarded, and others thought to be social misfits due to the inheritance of undesirable traits.

What Is the Biological Perspective

Thus, if concordance rates which can range from 0 to are significantly higher for identical twins than for fraternal twins, then this is evidence that genetics play an important role in the expression of that particular behavior.

Electrodes are attached to the scalp and brain waves can be traced. Studies of schizophrenia patients and their families, for example, have shown that the more closely a person is related to a schizophrenia patient, the greater their own risk of developing the disorder, which supports a role for genes in the disorder.

Penfield electrically stimulated different parts of the cerebral cortex in patients he was operating on. Also, studies comparing the behavior of twin raised apart have been criticized as the twins often share similar environments and are sometimes raised by non-parental family member.

Each of these biological aspects, the comparative, the physiological i.

Describe & Discuss the Biological Approach

He found that, under some circumstances, they would start having unusual experiences or vivid memories of past events. The theory is named biological determinism - heredity, more than environment or education, the idea went, caused social problems. Twins are concordant for a trait if both or neither of the twins exhibits the trait.

The results gained are also more objective as they are based on biology compared to subjective reporting or observations which also give the biological approach more validity. Even more sophisticated is the PET scan Positron Emission Tomography which uses a radioactive marker as a way of studying the brain at work.

Even more sophisticated is the PET scan Positron Emission Tomography which uses a radioactive marker as a way of studying the brain at work. The brain can influence many types of behavior. For example, some researchers have shown how behaviour can be affected by altered levels of sex hormones.

All of these involve comparing people with different degrees of genetic relatedness to see how similar they are in relation to a particular trait or behaviour. Methods of Studying the Brain It is important to appreciate that the human brain is an extremely complicated piece of biological machinery.

The genetic basis of behaviour has focused on trying to identify how much behaviour is influenced by genes and how much is influenced by the environment. Researchers who are interested in genetic influences may use twin, family history and adoption studies.

How do biopsychologists study human behaviour. Whilst most people regard this as a strength some would suggest that biopsychologists neglect an important aspect of being a person: Behaviors have their origins in specific locations of the brain.

Aggression may have served the purpose of increasing survival and protecting territory. The procedure is based on the principle that the brain requires energy to function and that the regions more involved in the performance of a task will use up more energy.

Discuss ethical considerations in research at the biological approach. For describe you will need to think of one ethical consideration that is very important for biological research, and describe it in detail – why it is particularly relevant to the biological approach, why it is necessary for studies to implement this consideration, and what the implications are if it is not applied.

The biological approach to psychology is one way to conceptualize and explain the human experience. The biological approach seeks to explain mental processes and behavior by focusing on the.

Theories within the biological approach support nature over nurture. However, it is limiting to describe behavior solely in terms of either nature or nurture, and attempts to do this underestimate the complexity of human behavior.

It is more likely that behavior is due to an interaction between nature (biology) and nurture (environment). Another objection to the biological approach would be its use of animal models as a basis for understanding human behaviour: given that each animal’s nervous system reflects its unique evolutionary niche and history, it might not be possible to draw clear conclusions about human behaviour from studies of other animals.

The biological approach in psychology is highly reductionist in its approach to the complexity of human behavior and emotion. Reducing our feelings and reactions to robot-like behavior is not only unethical, it also ignores the factors in our every day environment - our childhood experiences and the influence and behavior of friends and media.
