Biological Approach To Psychology Essay

Out of all the approaches to psychology, the biological approach uses the most scientific explanation for human behavior. According to Aidan Sammons, “The things people think and feel, say and do are caused, one way or another, by electrochemical events occurring within and between the neurons, that make up their nervous system, particularly those in the brain.” (p. 1) This is the basis of the biological approach. Psychologists favoring this approach believe that all human behavior is linked, somehow or someway, to the brain’s functions. According to the beliefs of these psychologists, each area of the brain influences different thinking and behavior. For example, language in humans is controlled by the cerebral cortex, but it contains two separate subsections. Broca’s area controls the production of speech and Wernicke’s area controls the comprehension of speech. Apart from the individual roles parts of the brain play, one’s behavior is also linked to the individual part’s connections to other parts of the brain and how they work together. Biopsychologists also believe that the genes a person inherits affects their behavior. Now, you might be thinking, genes! They have nothing to do with the brain! Well, my beautiful reader, you are incorrect. This theory applies perfectly to this approach because the development of a person’s brain is due to the genes they inherit.

This approach is focused on how evolution has shaped one’s mind and behavior. The basis of evolutionary psychology is that human behavior is the result of psychological adaptations that allowed humans to survive in ancestral environments. Evolutionary psychology is closely related to evolutionary biology, which is the theory that parts of an organisms body (examples in the human body include the lungs, heart or immune system) had to adapt to different environments over the course of
