The cognitive revolution marked a shift from behaviorism to a focus on internal mental processes. Dissatisfaction with behaviorism's limitations, advancements in computer science, and influences from linguistics and neuroscience fueled this paradigm change in psychology and related fields.
The computer metaphor played a crucial role, likening the mind to an information processing system. This approach emphasized internal representations and computations, leading to the development of cognitive architectures and models that simulated human cognitive processes.
Historical Context and Key Factors
Factors of Cognitive Revolution
- Dissatisfaction with limitations of behaviorism
- Unable to explain complex mental processes (language acquisition, problem-solving)
- Ignored internal mental states and focused solely on observable behavior
- Advancements in computer science and technology
- Development of information processing models provided new framework for understanding cognition
- Emergence of artificial intelligence (Turing test, logic theorist) inspired new approaches to studying the mind
- Influence of other disciplines
- Linguistics: Noam Chomsky's work on language challenged behaviorist explanations and emphasized innate cognitive structures
- Neuroscience: Discoveries about brain's structure and function (neurons, synapses) provided biological basis for cognitive processes
- World War II research
- Development of communication systems and information theory (Shannon's work) laid foundation for cognitive models
- Studies on human performance and decision-making (radar operators, cryptographers) highlighted importance of mental processes
Role of computer metaphor
- The computer as a model for the mind
- Information processing approach viewed mental processes as computations
- Mental processes likened to computer algorithms (search, retrieval, manipulation)
- Emphasis on internal representations and computations
- Symbols and rules as the basis for cognition (propositional representations, production systems)
- Manipulation of mental representations (transformations, mappings)
- Influence on the development of cognitive architectures
- Models of memory (short-term, long-term), attention (selective, divided), and problem-solving (means-ends analysis)
- Simulation of human cognitive processes (GPS, SOAR)
Impact and Paradigm Shift
Challenge to behaviorist paradigm
