The Cognitive Revolution in psychology marks a significant shift in the focus of psychological research and theory from the behaviourist emphasis on observable behaviour to an interest in the internal mental processes that underlie human cognition. Emerging in the mid-20th century, around the 1950s and 1960s, this revolution was fuelled by dissatisfaction with the limitations of behaviourism, particularly its neglect of mental processes such as thinking, memory, and problem-solving.
Key to the cognitive revolution was the analogy between the mind and the computer, suggesting that human cognition could be understood in terms of information processing. This perspective introduced the concept of the mind operating similarly to a computer, where sensory input is transformed, reduced, elaborated, stored, retrieved, and used to guide behaviour. This model laid the groundwork for cognitive psychology, which studies processes like perception, memory, thought, and problem-solving.
The cognitive revolution was also propelled by advances in other disciplines, such as linguistics, neuroscience, and computer science, which provided new methods and theoretical frameworks for understanding the mind. Notably, Noam Chomsky’s critique of behaviourist approaches to language acquisition highlighted the complexity of linguistic structures and the necessity of innate cognitive capacities, further challenging behaviourism and contributing to the cognitive perspective.
The impact of the cognitive revolution extends beyond psychology, influencing fields like education, where insights into cognitive processes have informed teaching methods and curriculum design, and artificial intelligence, where models of human cognition have guided the development of intelligent systems.
This paradigm shift reoriented psychology towards a comprehensive understanding of the human mind and its capacities, establishing cognitive psychology as a dominant field in the latter half of the 20th century and beyond, deeply influencing our understanding of mental processes and their application in various domains.
