(Walter Kintsch, 1998) I get the impression that the
above definition is not 'adequate', and that a truly
adequate definition of 'working memory' is not likely
to be all that simple.
Neither the traditionally assumed severe capacity
limits (7 +/- 2), nor the idea of moving content from
long-term memory to short-term ('working') memory and
back, seem to be generally valid.
Kintsch uses the terms 'short-term working memory'
(ST-WM) and 'long-term working memory' (LT-WM), as well
as the idea of 'retrieval structures' in order to theorize
the role of 'working memory' in text understanding.
