Individual Differences in Attention.
Abstract
This paper examines the implications of a simple resource competition model of attention (kahneman, 1973) for individual differences in performance in dual task situations. According to the model, an individual's performance on any task is determined by two factors: (a) the general mental resources available for that task, and (b) the efficiency of specific structures necessary to perform the task. In order to predict performance, information about each of these factors is necessary. This general model is discussed with respect to data obtained in the easy-to-hard paradigm. In this paradigm, subjects are asked to perform an easy primary task in conjunction with a secondary task. Performance on both the easy primary task and the secondary task are used to predict performance on a harder version of the primary task. The principles of formal information theory are used to show that performance on the secondary task, done in conjunction with the easy primary task, should improve prediction of the hard primary task. Data from several experiments using the 'easy-to-hard' paradigm support this conclusion. (Author)
