Psychologist study why people act in certain ways or react to different things differently. They also study what people consider a norm, at its simplest ;something like eating with a fork and a knife compared to eating with hand. They study how different human beings and genders precept stimulus and how they think and then react. Psychologists study human responses. Its like studying the brain to its atomic point but from a psychological perspective.
