Psychology has different approaches and sub-fields.
The approaches are:
Biological: How the body and brain enable emotions, memories, and sensory experience; how genes combine with environment to influence individual differences.
Evolutionary: How the natural selection of traits promoted the survival of genes.
Psycho-dynamic: How behavior springs from unconscious drives and conflicts.
Behavioral: How we learn observable responses.
Cognitive: How we encode, process, store, and retrieve information.
Humanistic: How we meet our needs for love and acceptance and achieve self-fulfillment.
Socio-cultural: How behavior and thinking vary across situations and cultures.
The sub-fields are:
Biological Psychology: Explores the links between brain and mind.
Developmental: Studies changing abilities from womb to tomb.
Cognitive: Experiments with how we perceive, think, and solve problems.
Educational: Studies influences on teaching and learning.
Personality: Investigates our persistent traits.
Social: Explores how we view and affect one another.
