Lecture Notes: Origins of Psychology and Wilhelm Wundt

Introduction

• Wilhelm Wundt is credited as the father of psychology.
• Ranked as the most important psychologist of all time, ahead of William James and Sigmund Freud.
• The video explores the origins of psychology, Wundt's introspection method, and psychology's emergence as a science.

Approaches in Psychology

• Behaviourist Approach: Focuses on observable behavior influenced by the environment. Ivan Pavlov's work is notable.
• Cognitive Approach: Studies internal mental processes and thoughts.
• Social Learning Theory: Emphasizes observational learning (e.g., Bandura).
• Psychodynamic Approach: Freud's focus on unconscious forces.
• Humanistic Approach: Emphasizes free will, self, and growth.
• Biological Approach: Explores how biological factors like genetics affect behavior.

Wilhelm Wundt and the Origins of Psychology

• Background: Wundt was originally a physiologist.
• Contribution: Moved the study of the mind to a scientific realm, separating it from philosophy.
• First Laboratory: Established the first experimental psychology lab in Leipzig, Germany, in 1879.

Method of Introspection

• Definition: Introspection involves examining one's own conscious experience.
• Process:
  • Participants presented with stimuli (e.g., a metronome).
  • Participants introspect and report emotions, sensations, and thoughts.
  • Wundt compared responses for similarities and differences.
• Controls: Ensured consistency (standardized stimuli presentation).
• Objective: Aimed for repeatability to verify results.

Limitations of Introspection

• Subjectivity: Self-reporting is subjective; no independent verification.
• B.F. Skinner criticized introspection for not being observable or objective.

Impact of Wundt's Work

• Legacy: Provided a foundation for future psychology.
• Training: Educated 186 graduate students, spreading research globally.

Evolution of Psychological Approaches

• Behaviourism (1900s): Objective measurement of behavior (e.g., Skinner's experiments with reward/punishment).
• Cognitive Approach (1960s): Focused on memory and mental processes with scientific methodology.
• Biological Approach (1980s): Studied genetics and brain chemistry.
• Cognitive Neuroscience (Present): Combines cognitive and biological approaches with advanced brain scanning technologies.

Conclusion

• Wundt's pioneering work laid the groundwork for scientific psychology.
• Modern technology allows observation of brain activity during mental processes, a development rooted in Wundt's initial efforts.
