Influence of working memory on adult age differences in matrix reasoning.

From: British Journal of Psychology | Date: May 1, 1993| Author: | Copyright information

The four studies reported in this article, involving a total of 401 adults ranging between 18 and 80 years of age, were designed to investigate how working memory might mediate adult age differences in matrix reasoning tasks such as the Raven's Progressive Matrices Test. Evidence of this mediation is available in the finding that statistical control of an index of working memory reduces the age- related variance in matrix reasoning performance by approximately 70 per cent. Because the age differences were nearly constant across items of varying difficulty, it was concluded that the factors ...
