Brief History of Psychology

Introduction to Psychology

  • Psychology studies behaviour and mental processes; evolved from philosophical speculation to scientific discipline.
  • Understanding modern psychology requires knowledge of its historical development.

Historical Overview

  • Three strands of psychology's history:
    • Philosophical roots: Questions about mind and soul.
    • Physiological/experimental beginnings: Linking mind to body and measurement.
    • Theoretical schools: Competing frameworks shaping research and practice.

Early Philosophical Roots

  • Key philosophers:
    • Plato: Rationalism; knowledge is innate, discovered through reasoning.
    • Aristotle: Empiricism; knowledge comes from sensory experience.
    • Descartes: Dualism; mind and body are distinct and interact.

Transition to Scientific Psychology

  • Late 19th century: Psychology becomes a science.
  • Wilhelm Wundt: Founded the first psychology lab in Leipzig (1879); structuralism focuses on breaking down mental processes via introspection.

Founding Schools of Thought

  • Key schools include:
    • Structuralism: Focus on structure via introspection.
    • Functionalism: Emphasis on mental processes adapting to environments.

    • Humanistic Psychology: Free will and self-actualization.
    • Cognitive Psychology: Examination of memory and problem-solving.
