The influence of strategies on relationships between working memory and cognitive skills.
The aim of this study was to test the effect of administration method on relationships between working memory span tasks and cognitive skills. Participants completed both participant-administered and experimenter-administered working memory measures in both verbal and visuospatial domains. Although the tasks were equally reliable, the additional time taken to implement strategies in the participant-administered tasks in the verbal domain reduced the correlations between working memory and reading comprehension and arithmetic. These findings did not extend to a visuospatial working memory measure, for which there was no significant difference between the participant-administered and experimenter-administered tasks in terms of their relationships with comprehension and arithmetic. However, performance on experimenter-administered working memory tasks in both verbal and visuospatial domains predicted unique variance in comprehension and arithmetic while controlling for scores on the participant-administered tasks. The results are discussed in terms of theoretical and practical implications for working memory research.
