Working memory and intelligence: Different constructs

The authors address agreements and disagreements with the M. J. Kane, D. Z. Hambrick, and A. R. A. Conway (2005; see record 2004-22408-004) and K. Oberauer, R. Schulze, O. Wilhelm, and H.-M. Süß (2005; see record 2004-22408-003) commentaries on P. L. Ackerman, M. E. Beier, and M. O. Boyle (2005; see record 2004-22408-002). They discuss the following issues: (a) the relationship between working memory (WM) and general intelligence (g), (b) the reanalyses included in the comments, (c) the use of a fixed-effects model versus a random-effects model for the meta-analysis, (d) the use of structural equation modeling analyses and structural coefficients as equivocal evidence for the relationship between WM and intelligence, and (e) the problem of confirmation bias in research on WM. Although the authors disagree with their commentators about the magnitude of the relationship between WM and g, in the final analysis it appears that all concerned parties agree that WM and intelligence are different constructs.
