What role does biological psychology primarily explore?

Biological psychology primarily focuses on the connections between biological processes and behavior. This discipline investigates how the brain, neurotransmitters, hormones, and genetics influence thoughts, feelings, and actions. By studying the underlying biological mechanisms, such as neurological functions and genetic predispositions, biological psychology seeks to explain behaviors in terms of physiological processes.

The other options are related to psychological aspects but do not capture the essential focus of biological psychology. Emotional regulation techniques pertain to therapeutic approaches rather than the biological underpinnings. The relationship between diseases and human behavior is more closely aligned with health psychology or behavioral medicine, while the development of individual cognitive strategies falls under cognitive psychology. Each of these areas explores important aspects of psychology; however, they do not emphasize the biological processes that drive behavior as biological psychology does.
