In Psychology , cognitivism is a theoretical approach in understanding the mind, which argues that mental function can be understood by Quantitative , Positivist and Scientific methods, and that such functions can be described as Information Processing models. THEORETICAL APPROACH Cognitivism has two major components, one methodological, the other theoretical. Methodologically, cognitivism adopts a Positivist approach and the belief that psychology can be (in principle) fully explained by the use of Experiment , Measurement and the Scientific Method . This is also largely a Reductionist goal, with the belief that individual components of mental function (the 'cognitive architecture') can be identified and meaningfully understood. The second is the belief that Cognition consists of discrete, internal mental states ( Representations or Symbols ) whose manipulation can be described in terms of rules or Algorithm s. Cognitivism became the dominant force in Psychology in the late- 20th Century , replacing Behaviorism as the most popular paradigm for understanding mental function. Cognitive Psychology is not a wholesale refutation of behaviorism, but rather an expansion that accepts that mental states exist. This was due to the increasing criticism towards the end of the 1950s of behaviorist models. One of the most notable criticisms was Chomsky's argument that language could not be acquired purely through conditioning, and must be at least partly explained by the existence of internal mental states. CRITICISMS OF PSYCHOLOGICAL COGNITIVISM Cognitivism has been criticised in a number of ways. methods cannot be meaningfully used on something which is inherently irreducible to component parts. Hubert Dreyfus has been the most notable critic of cognitivism from this point of view. Humanistic Psychology draws heavily on this philosophy, and practitioners have been among the most critical of cognitivism. In the 1990s , various new theories emerged and challenged Cognitivism and the idea that thought was best described as computation. Some of these new approaches, often influenced by phenomenological and post-modernist philosophy, include Situated Cognition , Distributed Cognition , Dynamicism , Embodied Cognition . Some thinkers working in the field of Artificial Life (for example Rodney Brooks ) have also produced non-cognitivist models of cognition. The idea that mental functions can be described as information processing models has been criticised by Philosopher John Searle and Mathematician Roger Penrose who both argue that computation has some inherent shortcomings which cannot capture the fundamentals of mental processes.
Another argument against cognitivism is the problems of Ryle's Regress or the Homunculus Fallacy . Cognitivists have offered a number of arguments to refute these attacks. The focused issues that interest cognitive psychologists consist of the inner mechanism of human thought and the processes of knowing. Cognitive psychologists have attempted to dig out the response to mental structures, such as what is saved and how it is recorded of course in our brain, once more to mental processes concerning how the integration and retrieval of information is operated. The theoretical assumptions in cognitive psychology lend instructional systems a hand in the design of efficient processing strategies for the learners to acquire knowledge, e.g. mnemonic devices to reduce the workload of the short-term memory, rehearsal strategies to maintain information, and the use of metaphors and analogies to relate meaning of the new information to prior knowledge.
