Information Processing

I nformation processing, as a paradigm (cf. Broadbent, 1958), has played and is playing a decisive role in cognitive psychology. According to this approach, cognition is a sequence of individual processing stages. The sequence begins with a stimulus being translated into a perception pattern by physiological processes. If a section of this pattern attracts attention, a block of working memory is allocated to it. Rehearsal and elaboration processes subsequently serve to transfer some of the original stimulation into long-term memory stores. During recall, these stores are searched, and bits of information are retrieved and placed at the disposal of working memory. Models presented by Atkinson and Shiffrin (1968) and Waugh and Norman (1965) entail and integrate the various indicated basal processes.
