Practicalities – discussion of class study strategies
Warm-up – see activity sheet
- Influences on Functionalism - Charles Darwin - Phylogenetic development and continuity - Adaptation (variation and selection) - Francis Galton - Applied Darwin’s theory to the human mind - Studies of Eminence, mental capacity, individual differences, quantitative techniques
- William James - Mind is an organ that adapts to its environment - Structural and functional - Pragmatist - Chapters on reasoning, associationism
John Dewey - Recognition of a problem, isolation of the relevant features, formulation of alternative solutions, testing the solution
Early psychologists tried introspection (self-reflection) as a way to study thinking, but found it too hard to do reliably
- John B. Watson - Focused on ‘human behavior’ - No point to study inaccessible events of the mind - Instead must focus on Stimulus-Response
- B.F. Skinner - Operant conditioning; Classical conditioning
Classical Conditioning | Operant Conditioning- Reinforcement or punishment- Change probability of response |
Focus on BEHAVIORS, explanations in terms of -
Works well for simple learning scenarios ... but, how would a behaviorist explain language? -
How do you account for accurate processing of totally new experiences?
How do you explain thinking using S-R theory?
- Behaviorists went to the opposite extreme by finding rules of behavior and learning without any mention of what happens inside the head (thinking)
- It is still possible to talk about the mental without resorting to introspectionism?
Cognitive Psychology - Cognitive psychology studies the components (pieces) of thinking, from perception to action. - Modern cognitive psychology uses careful experimentation to figure out what (information processing) steps in the head produce behavior
Foundations - Information Theory - Claude Shannon - A Mathematical Theory of Communication (1948)
- Computation - Alan Turing - computability (algorithms) (1936)
- Donald Broadbent - improve human skills; theories of IP
- George Miller - chunks of information in memory (1956)
- Alan Newell and Herbert Simon (1955)
- “Cognitive Psychology”, Ulric Neisser’s - published (1967)
Overview and Approaches
Example: approaching an issue
- Why do people forget? - Decay vs. interference - Both predict people forget with time
- How do you tell which is right?
- Find a situation with different predictions:
* Do people forget as much when asleep?
* Decay - __________;…
