psych chunk 1 - foundations of psychology

Empirical Research

  • Definition: Knowledge gained through direct observation and measurement, not opinions or intuition.

  • Example: Measuring reaction time to test attention span (not just guessing who “seems” more attentive).


Scientific Method

  1. Question/Problem → identify what you want to study.

  2. Hypothesis → make a testable prediction (must be specific).

  3. Test → conduct observation, surveys, or experiments.

  4. Analyze Results → look for patterns, use statistics.

  5. Conclude/Revise Theory → confirm or adjust hypothesis.

  • Goal: keep research systematic and objective (so findings are reliable).


Basic vs. Applied Research

  • Basic Research: Expands knowledge for the sake of curiosity.

    • Example: Studying how memory works in the brain, even if no immediate use.

  • Applied Research: Uses psychology to solve practical, real-world problems.

    • Example: Creating therapy techniques to treat anxiety.


Definition of Psychology

  • The scientific study of behaviour (observable actions) and mental processes (thoughts, feelings, memories, etc.).

  • Psychology aims to describe, explain, predict, and control behaviour.


Key Debates

  • Nature vs. Nurture:

    • Nature: behaviour comes from genetics and biology.

    • Nurture: behaviour shaped by experience and environment.

    • Today → most psychologists agree it’s an interaction of both.

  • Mind vs. Body (Dualism vs. Monism):

    • Dualism (Descartes): mind and body are separate — mind is non-physical.

    • Monism: mind and body are connected — mental activity comes from physical brain processes.

    • Modern psychology = leans toward monism (brain → mind).
