Abstract

It has been suggested that situations requiring the division of attention between competing activities can tap abilities which are central to cognitive functioning. This paper attempted to determine whether there are identifiable characteristics in the single tests that will help to predict changes in general factor loadings when they are presented as components of competing tasks. The framework for the study was provided by the theory of fluid (GO and crystallized (Gc) intelligence. A battery of single and competing tasks was presented to 126 subjects. The competing tasks represented a variety of within and across factor combinations from different levels of the Gf/Gc hierarchy. Modality of presentation was also varied in some combinations. The results indicate that single and competing tasks measure the same broad ability of the Gf/Gc theory and that general factor loadings can decrease as well as increase in the competing task situation. There is also evidence that these tendencies depend, to some extent, on the degree to which the tasks require the same cognitive factors or use the same sensory modalities. Overall, it is assumed that competing tasks do make greater demands on general ability but that, unless the requirements of the single tests themselves are relatively small, performance breakdown, with an accompanying decrease in general factors loadings, is the likely outcome.
