The correct answer emphasizes the primary aim of biological psychology, which is to explore the interactions between biological processes and behavior. This area of psychology investigates how the brain, neurotransmitters, hormones, and genetics influence our thoughts, feelings, and actions. By understanding these connections, researchers can better comprehend how physical factors affect mental functions and behavior, therefore providing insights into various psychological phenomena.

The other choices, while they address important areas in psychology, do not encapsulate the specific aim of biological psychology. The study of psychological disorders tends to focus more on behavioral symptoms and therapeutic interventions rather than the biological underpinnings. The analysis of human cultures relates to cultural psychology or anthropology, which looks at how culture shapes behavior and thinking. Similarly, the investigation of learning and memory is more aligned with cognitive psychology, focusing on mental processes rather than the biological basis of behavior.
