1. The Core Intellectual Dialectic
Modern psychology began with a fundamental clash between two paradigms:
- Structuralism asked: "WHAT are the elemental contents of conscious experience, and HOW are they combined?"
- Functionalism asked: "WHY does consciousness exist, and WHAT is its practical biological utility for survival?"
| Dimension | Structuralism (Cornell) | Functionalism (Chicago & Columbia) |
|---|---|---|
| Pioneering Leaders | Edward Bradford Titchener | William James, John Dewey, James R. Angell |
| Philosophical Roots | British Associationism / German Wundtian laboratory | Darwinian Evolution / American Pragmatism |
| Subject Matter | Static elemental contents of conscious experience | Dynamic mental operations adapting to environment |
| Primary Method | Rigorous experimental introspection (Innere Wahrnehmung) | Eclectic: observation, testing, physiological measures |
| Target Population | Normal, trained adult humans exclusively | Children, animals, clinical populations, adults |
| Applied Psychology | Rejected outright; insisted on pure basic science | Embraced; applied to education, industry, testing |
2. Structuralism: Titchener’s Atomic Science of Mind
Edward Bradford Titchener (1867–1927), Wundt’s British student, established Structuralism at Cornell University in 1892.
A. Subject Matter & The Stimulus Error
- Definition of Mind: The accumulated sum total of mental experiences across a lifespan; Consciousness is the sum total of experiences at any given moment.
- The Stimulus Error (Reizfehler): The cardinal methodological violation in structuralist introspection. It occurs when an observer reports the meaning, identity, or physical name of the stimulus object rather than the raw, immediate sensory elements.
- Example: Looking at an apple and reporting "I see an apple" is a stimulus error. The valid structuralist report describes "a crimson curved contour, smooth texture, and bright specular reflection".
B. The Three Elementary States of Consciousness
Titchener broke consciousness into three irreducible atomic classes:
- Sensations: Elementary units of perception aroused by external physical stimuli via sense organs (sounds, sights, smells).
- Images: Elementary units of memory and imagination (faint copies of past sensations).
- Affections: Elementary units of emotion and feeling.
