Psychological Domains

Psychological domains are the various ways psychologists study and apply psychology in real life. 

There are four essential domains in psychology: 

Biological : Hormones, natural processes, adaptation and brain mechanics. Biological psychologists seek to understand how our brain affects our behavior. 

Cognitive : Mental abilities, knowing, remembering, thinking and perception.

Developmental : Progression from infancy, to childhood, to adolescence, to adulthood mentally and behaviorally.

Clinical (Mental Health) : Assess and treat mental, emotional, and behavior disorders. 

These domains or pillars are the fundamentals to more contemporary disciplines of psychology:

Counselling : Professionals who aid people to cope with crises and/or help people adjust to life transitions or make lifestyle changes (i.e., divorce, marriage, loss)

Educational : The methods and influences on teaching and learning. 

Positive : Encourage acceptance of one's past and optimism about one's future experiences.

Industrial-organizational : The use of psychological concepts and methods to select employees, boost morale, design products, and better business functioning.

Personality : Investigating and logging persistent traits and consistent characteristics / behaviors of people (i.e., temperament, interests, etc.)

Social : How expressions of emotions vary across cultural and situational contexts (i.e., cataloging and explaining how or why people act in different social and cultural situations)
