Cognitive psychology views individuals as information processors, analogous to computers, emphasizing the importance of internal mental processes between environmental stimuli and responses. It aims to understand the structures and processes that govern cognitive performance, exploring concepts like selective attention and multitasking. This field has influenced various other disciplines, including social learning theory, cognitive neuropsychology, and artificial intelligence.
Cognitive Psychology and information Processing
- 1. Cognitive Psychology By Queen Santos
- 2. • 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.
- 3. •Cognitive psychology is also suggesting that it is possible and desirable to study the internal mental or meditational processes that lie between the stimuli (in our environment) and the response we make.
- 4. Basic Assumptions Information made available by the environment is processed by a series of processing systems (e.g. attention, perception, short-term memory); 1.
- 5. Basic Assumptions These processing systems transform or alter the information in systematic ways.2.
- 6. Basic Assumptions The aim of research is to specify the processes and structures that underlie cognitive performance; 3.
- 7. Basic Assumptions Information processing in humans resembles that in computers.4.
- 8. Essentially, a computer • codes (i.e. changes) information, • stores information, • uses information, and • produces an output (retrieves info). The idea of information processing was adopted by cognitive psychologists as a model of how human thought works.
- 9. Hence the information processing approach characterizes thinking as the environment providing input of data, which is then transformed by our senses. The information can be stored, retrieved and transformed using “mental programs”, with the results being behavioral responses.
- 10. 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).
- 12. 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. Cocktail Party Syndrome), and how many things we can attend to at the same time (attentional capacity/multitasking).
- 13. • Broadbent and others in the 1950's adopted a model of the brain as a limited capacity information processing system, through which external input is transmitted. Information processing models consist of a series of stages, or boxes, which represent stages of processing. Arrows indicate the flow of information. * Input processes are concerned with the analysis of the stimuli. * Storage processes cover everything that happens to stimuli internally in the brain and can include coding and manipulation of the stimuli. * Output processes are responsible for preparing an appropriate response to a stimulus.
