This study represents a continuation of efforts to relate hypotheses drawn from psychoanalytic theory to psychological theory and, in particular, ego psychology to cognitive functioning. The capacity to deploy attention selectively was measured on 8 perceptual tasks, including such problems as Embedded figures, rod and frame, and various measures of illusion. Performance on all 8 tasks was intercorrelated and the matrix factor analyzed. The result was 3 factors, viz., a "field articulation factor" involving "individual consistencies in the capacity to achieve differential response to relevant vs, irrelevant cues," a "scanning factor," and a factor which represents "individual differences in proneness to satiation effects." The results are discussed from the pont of view of their contribution towards cognitive function and the individual's "cognitive style," and are related to several theoretical frames of reference.
