Once again, this kind of memory doesnt last long, only about 15 to 20 seconds.Cynthia Vinney, Ph.D., is a research fellow at Fielding Graduate Universitys Institute for Social Innovation.She has co-authored two books on psychology and media engagement.Information processing theory is a cognitive theory that uses computer processing as a metaphor for the workings of the human brain.
Serial Model For Information Processing Code It IntoMiller and other American psychologists in the 1950s, the theory describes how people focus on information and encode it into their memories. It was initially proposed in the mid-50s by American psychologists including George Miller to explain how people process information into memory. The most important theory in information processing is the stage theory originated by Atkinson and Shiffrin, which specifies a sequence of three stages information goes through to become encoded into long-term memory: sensory memory, short-term or working memory, and long-term memory. During the first half of the twentieth century, American psychology was dominated by behaviorism. Behaviorists only studied behaviors that could be directly observed. This made the inner-workings of the mind seem like an unknowable black box. ![]() The metaphor helped psychologists explain the different processes the brain engages in, including attention and perception, which could be compared to inputting information into a computer, and memory, which could be compared to a computers storage space. This was referred to as the information processing approach and is still fundamental to cognitive psychology today. Information processing is especially interested in how people select, store and retrieve memories. Miller developed the theory and also contributed the idea that one can only hold a limited number of pieces of information in short-term memory. Serial Model For Information Processing Plus Or MinusMiller specified this number as seven plus or minus two (or five to nine chunks of information), but more recently other scholars have suggested the number may be smaller. The development of the information processing framework has continued through the years and has been broadened. Below are four models that are especially important to the approach. In 1968, Atkinson and Shiffrin developed the stage theory model. The model was later modified by other researchers but the basic outline of stage theory continues to be a cornerstone of information processing theory. The model concerns how information is stored in memory and presents a sequence of three stages, as follows. This kind of memory is exceedingly brief, only lasting up to 3 seconds. ![]() Sensory memory cant attend to every piece of information in the environment, so it filters out what it deems irrelevant and only sends what seems important to the next stage, short-term memory. The information thats most likely to reach the next stage is either interesting or familiar.
