Reflection on the Biological Approach Psychology is the scientific study of the mind, its processes, and functions, particularly how these effect behaviors. Psychologists’ goal is to describe, explain, predict, and control. Psychologists base their studies on different approaches, the cognitive approach, biological approach, humanistic approach, evolutionary approach, bio-psychosocial, psychoanalytical approach, and sociocultural approach. The biological approach is examines how an organisms biology, such as genes, hormones, and nervous system effect its behavior such as motivations, emotional responses, and personality. The University of Colorado recently published a study that explains how an aspect of human biology connects to stress.…show more content…
Addictive substances cause an increase a neurotransmitter called dopamine, which goes to a part of the brain called the nucleus accumbens and produces pleasurable sensations/responces. This pathway is called the reward pathway. Naturally dopamine release does not occur often, so when one repeatedly uses drugs that cause dopamine release receptor cells become overwhelmed and shut down. The brains ability to produce dopamine by itself decreases, but the need for it remains, creating a dependency on the substance. Addictive substances are classified into two catagories, stimulis and depressants. Stimulants such as cocaine stimulate the cntral nervouse system while depressants such as heroine depress the central nervous system. Cocaine is a powdery white substance that can be inhaled or injected, as listed above it is a stimulant that effects the central nervous system. Cocaine increases the levels of the dopamine in the brain. Normally dopamine is released and then recycled back into the cell that released it, therefore shutting down the signal of pleasure between neurons. Cocaine prevents the dopamine from getting recycled and causes a build up of it in the synapse, or space between neurons. This enhances the dopamine signal and therefore causes a flood of dopamine, which causes cocaine’s jittery energetic ‘high’. Cocaine is addictive due to the rush of dopamine and the cells inability to produces dopamine…show more content…
The biological approach does not take into account the social, economic, and environmental factors that play an important role in behavior and personality. For example, the biological approach would not be able to explain a person with extremely high intelligence if that person showed no particularly different brain functions or genetics. This person’s intelligence may have come from family factors or environmental factors, but the biological approach does not account for those. Another example would be if a patient had a mental breakdown , but had no family history of psychotic breakdowns and has a fully functioning brain. This breakdown may have resulted from work related stress or an interpersonal relationship, but once again the biological approach does not take these factors into
