"Is working memory capacity Spearman's g?"

measurement. Publisher Lawrence Erlbaum Associates, Inc Mahwah. 1996.

 Abstract: C. Spearman's remarkable contributions to psychology centered
around his identifying the general factor in human cognition / he developed
numerous methods--still in use today--for analyzing ability test scores,
including reliability and factor analysis / these methods, particularly
factor analysis, enabled Spearman to establish the necessity of a general
factor of cognition, that is, a factor that influences virtually every
cognitive performance / [suggests] that working memory capacity is more
highly related to performance on cognitive tests, and is more highly related
to learning, both short-term and long-term, than any other cognitive factor
/ [suggests that] working memory capacity may indeed be essentially C.
Spearman's g /// working memory and other information processing abilities
[findings from traditional psychometrics, ties to cognitive psychology,
evaluation of the CAM framework] / working memory and reasoning ability /
working memory and cognitive skill acquisition [logic gates study, computer
programming study] / components of working memory ((c) 1997 APA/PsycINFO,
