The Limited Capacity Model of Motivated Mediated Message Processing or LC4MP is an explanatory theory that assumes humans have a limited capacity for cognitive processing of information, as it associates with mediated message variables; moreover, they (viewers) are actively engaged in processing mediated information [1] Like many mass communication theories, LC4MP is an amalgam that finds its ...
Information processing theory is the approach to the study of cognitive development evolved out of the American experimental tradition in psychology. Developmental psychologists who adopt the information processing perspective account for mental development in terms of maturational changes in basic components of a child's mind.
In cognitive psychology, information processing is an approach to the goal of understanding human thinking that treats cognition as essentially computational in nature, with the mind being the software and the brain being the hardware. [1] It arose in the 1940s and 1950s, after World War II. [2]
[5] [6] This change can be viewed as the result of developmental changes in information processing capacity. [6] Information processing is a mechanism that is used across many different domains of cognitive functioning, and thus can be seen as a domain-general mechanism.
An early quantification of the capacity limit associated with short-term memory was the "magical number seven" suggested by Miller in 1956. [20] Miller claimed that the information-processing capacity of young adults is around seven elements, referred to as "chunks", regardless of whether the elements are digits, letters, words, or other units.
Broadbent was the first to describe the human attentional processing system using an information processing metaphor. [2] In this view, Broadbent proposed a so-called "early selection" view of attention, such that humans process information with limited capacity and select information to be processed early.
"The Magical Number Seven, Plus or Minus Two: Some Limits on Our Capacity for Processing Information" [1] is one of the most highly cited papers in psychology. [2] [3] [4] It was written by the cognitive psychologist George A. Miller of Harvard University's Department of Psychology and published in 1956 in Psychological Review.
Information may only be stored in long term memory after first being attended to, and processed by, working memory. [citation needed] Working memory, however, is extremely limited in both capacity and duration. [6] These limitations will, under some conditions, impede learning.
