#DISADVANTAGES OF SERIAL PROCESSING OPERATING SYSTEM SERIES#

The information processing models assume serial processing of stimulus inputs. However, there are a number of evaluative points to bear in mind when studying these models, and the information processing approach in general. Output processes are responsible for preparing an appropriate response to a stimulus.ДЄ number of models of attention within the Information Processing framework have been proposed including:Д«roadbent's Filter Model (1958), Treisman's Attenuation Model (1964) and Deutsch and Deutsch's Late Selection Model (1963).Storage processes cover everything that happens to stimuli internally in the brain and can include coding and manipulation of the stimuli.Input processes are concerned with the analysis of the stimuli.Arrows indicate the flow of information from one stage to the next.

Information processing models consist of a series of stages, or boxes, which represent stages of processing. One way of conceptualizing attention is to think of humans as information processors who can only process a limited amount of information at a time without becoming overloaded.Д«roadbent and others in the 1950s adopted a model of the brain as a limited capacity information processing system, through which external input is transmitted. Cocktail Party Syndrome), and how many things we can attend to at the same time (attentional capacity). Psychologists are interested in what makes us attend to one thing rather than another ( selective attention) why we sometimes switch our attention to something that was previously unattended (e.g. When we are selectively attending to one activity, we tend to ignore other stimulation, although our attention can be distracted by something else, like the telephone ringing or someone using our name. Information Processing and Selective Attention The information can be stored, retrieved and transformed using вЂњmental programsвЂќ, with the results being behavioral responses.Д¬ognitive psychology has influenced and integrated with many other approaches and areas of study to produce, for example, social learning theory, cognitive neuropsychology and artificial intelligence (AI). Hence the information processing approach characterizes thinking as the environment providing input of data, which is then transformed by our senses. behavior) might be, for example, to read what you can see on a printed page. This information is can be used by other parts of the brain relating to mental activities such as memory, perception and attention. The idea of information processing was adopted by cognitive psychologists as a model of how human thought works.ДЇor example, the eye receives visual information and codes information into electric neural activity which is fed back to the brain where it is вЂњstoredвЂќ and вЂњcodedвЂќ. The use of the computer as a tool for thinking how the human mind handles information is known as the computer analogy.Д®ssentially, a computer codes (i.e., changes) information, stores information, uses information, and produces an output (retrieves info). The computer gave cognitive psychologists a metaphor, or analogy, to which they could compare human mental processing. The development of the computer in the 1950s and 1960s had an important influence on psychology and was, in part, responsible for the cognitive approach becoming the dominant approach in modern psychology (taking over from Behaviorism). (4) information processing in humans resembles that in computers. (3) the aim of research is to specify the processes and structures that underlie cognitive performance (2) these processing systems transform or alter the information in systematic ways attention, perception, short-term memory)

(1) information made available by the environment is processed by a series of processing systems (e.g. The information processing approach is based on a number of assumptions, including:

At the very heart of cognitive psychology is the idea of information processing.Д¬ognitive psychology sees the individual as a processor of information, in much the same way that a computer takes in information and follows a program to produce an output.
