Applications[ edit ] The term "task" is often used interchangeably with activity or process. Tasks may be identified and defined at multiple levels of abstraction as required to support the purpose of the analysis. A critical task analysis, for example, is an analysis of human performance requirements which, if not accomplished in accordance with system requirements, will likely have adverse effects on cost, system reliability, efficiency, effectiveness, or safety.
Saul McLeodpublished At the very heart of cognitive psychology is the idea of information processing. Cognitive 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.
Basic Assumptions The information processing approach is based on a number of assumptions, including: Computer - Mind Analogy An analysis of cognitive information processing development of the computer in the s and s 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.
The computer gave cognitive psychologists a metaphor, or analogy, to which they could compare human mental processing. The use of the computer as a tool for thinking how the human mind handles information is known as the computer analogy.
Essentially, a computer codes i. The idea of information processing was adopted by cognitive psychologists as a model of how human thought works. This information is can be used by other parts of the brain relating to mental activities such as memory, perception and attention.
Hence the information processing approach characterizes thinking as the environment providing input of data, which is then transformed by our senses. Cognitive 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.
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.
Cocktail Party Syndromeand how many things we can attend to at the same time attentional capacity. 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.
The Information Processing System Information processing models consist of a series of stages, or boxes, which represent stages of processing. Arrows indicate the flow of information from one stage to the next.
Critical Evaluation A number of models of attention within the Information Processing framework have been proposed including: However, there are a number of evaluative points to bear in mind when studying these models, and the information processing approach in general.
The information processing models assume serial processing of stimulus inputs. Serial processing effectively means one process has to be completed before the next starts. Parallel processing assumes some or all processes involved in a cognitive task s occur at the same time. There is evidence from dual-task experiments that parallel processing is possible.
It is difficult to determine whether a particular task is processed in a serial or parallel fashion as it probably depends a on the processes required to solve a task, and b the amount of practice on a task. Parallel processing is probably more frequent when someone is highly skilled; for example a skilled typist thinks several letters ahead, a novice focuses on just 1 letter at a time.
The analogy between human cognition and computer functioning adopted by the information processing approach is limited. Computers can be regarded as information processing systems insofar as they: BUT - i the human brain has the capacity for extensive parallel processing and computers often rely on serial processing; ii humans are influenced in their cognitions by a number of conflicting emotional and motivational factors.
Most laboratory studies are artificial and could be said to lack ecological validity. In everyday life, cognitive processes are often linked to a goal e. Although these laboratory experiments are easy to interpret, the data may not be applicable to the real world outside the laboratory.
More recent ecologically valid approaches to cognition have been proposed e. Attention has been studied largely in isolation from other cognitive processes, although clearly it operates as an interdependent system with the related cognitive processes of perception and memory.
The more successful we become at examining part of the cognitive system in isolation, the less our data are likely to tell us about cognition in everyday life.
