Final answer:
The nomothetic approach in biological psychology involves studying large groups to identify general principles, such as using fMRI to find common neural patterns associated with anxiety.
Step-by-step explanation:
An example of how the nomothetic approach is used in biological psychology involves the study of how certain brain structures are involved in psychological processes and behaviors. Researchers using the nomothetic approach may perform brain imaging studies on large groups of individuals to identify common neural patterns associated with specific cognitive functions or emotional responses.
For instance, when studying the biological basis of anxiety, researchers might use fMRI to examine brain activity across a significant sample of people with anxiety disorders, searching for consistent patterns. The goal is to find general laws or principles that apply broadly to our understanding of how the nervous system generates behavior.
