A field of study that explores how biological factors, such as genetics and brain function, influence behavior, emotions, and mental processes.
Biopsychology helps us understand how our brain affects our thoughts and actions.
Biopsychology → It is formed from "bio-" (from Greek "bios", meaning life) and "psychology" (from Greek "psyche", meaning soul or mind, and "logos", meaning study). The word refers to the study of the biological basis of behavior and mental processes, combining life sciences with psychology.
Think of 'life' ('bio-') being studied in relation to the 'mind' ('psychology') — that's what biopsychology is all about.
