The Biological Approach
The biological approach is based on the medical paradigm, which stresses the involvement of the brain and body in the development of illnesses. Abnormalities are thought to be mental illnesses. As a result, the method evaluates human behavior and cognition from a physical standpoint. Chemical processes, genetic factors, and biological brain functioning based on brain areas are three major views used by bio-psychologists to explain human behavior.
The Chemical Viewpoint
To begin, the chemical viewpoint holds that the brain is dependent on chemicals such as neurotransmitters and hormones to convey information between brain neurons. A disorder that causes an increase or decrease in the synthesis of these chemicals in different areas of the brain produces abnormalities in normal behavior and thinking. For example, high testosterone results in an increased tendency of taking risks.
The Genetic Perspective
Secondly, the genetic perspective emphasizes genetics and inheritance as significant influences on particular behavior. For instance, schizophrenia, a psychological abnormality whose characteristics are: hallucinations, disorganized behavior, and speech, delusions among other symptoms, are partly caused by faulty genes. Such genes are responsible for development and functioning of mental processes.
The Organic Brain Functioning Areas
Finally, the organic brain functioning areas explain human behavior and functioning based on specific localized brain areas and how they connect and communicates with other parts. For example, the Broca's and the Wernicke's areas control the language function. These are speech areas that link other regions to influence auditory memory and thinking.
Conclusion
In conclusion, the biological approach precisely takes a scientific view of human behavior that focuses on features evident in most people, explaining psychological illnesses as consequences of defective genetics, chemical brain processes, and defective brain areas. Such defects are therefore targeted pharmacologically to treat the conditions.
