Working memory capacity (WMC)

In cognitive psychology, working memory capacity (WMC) refers to a particular measurement of working memory derived from operation span tasks (Reisberg, 2018). In actuality, the test measures how well an individual can keep a particular chunk (see: chunks) of information in working memory while allocating attentional (cognitive) resources, working with other tasks.
