Abstract
Working memory capacity: the need for process task-analysis
Highlights
We use working memory (WM) to follow directions, figure out how much things cost and keep up with a conversation
If we accept that WM estimates they summarized correspond to the number of items a child can simultaneously hold and manipulate, average scores can be used to identify the WM capacity limits of each age group (Table 1)
The first quantification of WM capacity limit was given by Miller (1956)
Summary
We use working memory (WM) to follow directions, figure out how much things cost and keep up with a conversation. Simmering and Perone (2013) made a noble effort to review data on WM capacity development, and their work will be an important reference for future studies. There is so much variability in the findings that understandably, Simmering and Perone (2013) avoided the discussion of WM capacity limits across development.
