Cognitive load. In cognitive psychology, cognitive load refers to the amount of working memory resources used. However, it is essential to distinguish it from the actual construct of Cognitive Load (CL) or Mental Workload (MWL), which is studied widely in many disciplines. According to work conducted in the field of instructional design and ...
He researched the capacity of the working memory, discovering that people can only hold up to 7 plus or minus 2 items. He also created the term chunking when explaining how to make the most of our short-term memory. [7] Two other theorists associated with the cognitive information processing theory are Richard C.

That limit—reflecting the capacity of short-term memory and originally estimated at seven plus or minus two items (Miller, 1956)—figures prominently in explaining performance in numerous cognitive tasks (Simon, 1990). Typically it is regarded as a constraint that hinders performance." (Kareev p.280) Reference: Kareev, Yaakov (2005) And Yet ...
