# Biological Perspective — AP Psychology Definition & Exam Guide

## Definition

The biological perspective in psychology is a way of looking at psychological issues by studying the physical basis for animal and human behavior. It's one of the major perspectives in psychology and involves such things as studying the brain, immune system, nervous system, and genetics.

## Additional Context

- **Theoretical Perspectives**: The biological perspective in psychology emphasizes the influence of biology on our behavior and mental processes. It looks at aspects like genetics, neurotransmitters, brain structures, and the evolutionary background to explain individual differences and behaviors.
- **Study And Research Findings**: Pioneering studies by researchers such as Paul Broca and Carl Wernicke identified specific brain regions linked to language processing. Neuroimaging research, including fMRI and PET scans, has allowed for the mapping of brain activity during various cognitive tasks, further supporting the biological perspective.
