Study Notes

Focuses on how individuals' thoughts, feelings, and behaviors are influenced by others and social situations.
Includes concepts like conformity, obedience, groupthink, persuasion, attitudes, and prejudice.
Investigates how social factors impact individual decision-making, behavior, and relationships.

Cognitive Psychology

Studies mental processes like memory, attention, perception, language, problem-solving, and decision-making.
Investigates how these processes work and the brain structures and mechanisms involved.
Explores topics like memory encoding, storage, retrieval, attentional mechanisms, and problem-solving strategies.
Also explores intelligence, and how intelligence and other mental capacities develop over time

Developmental Psychology

Examines changes in thoughts, behaviors, and emotions over a lifespan, from conception to old age.
Investigates how biological, social, and environmental factors influence development.
Focuses on physical, cognitive, social, and emotional changes at different stages.
