Subject-Task Interaction in Selective Attention Research

Two methods of investigating human information processing, the one focusing on the manipulation of experimental tasks and the other emphasizing individual differences, were compared. The design utilized the experimental tasks of Treisman and Riley (1969) while examining for individual differences on the basis of Witkin's field-articulation dimension. The findings of Treisman and Riley were replicated, while no differences were found among Ss categorized on the individual-difference dimension, suggesting that task variables were most important in performance requiring selective attention.
