Study Notes

Key Concepts of Differential Psychology

  • Intelligence: The capacity to comprehend complex ideas, solve problems, and adapt by learning from the environment.
  • Personality: A collection of stable characteristics impacting behavior and emotions, organized in a hierarchy.
  • Trait: A consistent characteristic influencing how a person behaves in various situations.
  • Identity: A person's sense of self; reputation how others perceive and judge them.

Differences Between Individuals

  • Physical Differences: Variations in height, weight, body type, and hair.
  • Physiological Differences: Variations in blood pressure, hormones, metabolism, and internal functions.
  • Surprising Differences: Unique traits like organ placement, bone/finger variations.
  • Developmental Differences: Changes across the lifespan, affecting personality and abilities (e.g., puberty timing, aging).

Cronbach (1957) – Two Disciplines of Scientific Psychology

  • Experimental Psychology: Focuses on manipulating variables to study cause-and-effect relationships in behavior under different conditions.
  • Correlational Psychology: Studies links between genetic, developmental, and environmental factors to understand individual differences in personality and intelligence.
