Individual Differences in Learning and Cognitive Abilities. Final Report.
Ackerman, Phillip L.
This final report reviews a program of theoretical and empirical research focusing on the ability determinants of individual differences in skill acquisition. An integrative framework for information processing and cognitive ability determinants of skills is presented, along with principles for ability-skill relations. Three major patterns of individual differences in skill acquisition are considered: (1) changes in between-subject variability; (2) the simplex pattern of trial intercorrelations; and (3) changing ability-performance correlations with practice. In addition to a review of previous theory and data, experimental manipulations are used to evaluate the cognitive ability demands associated with information processing parameters of skilled performance. A complex air traffic controller simulation task used in several investigations is introduced, along with empirical tests of theoretical principles. Examinations of practice-related between-subject variance changes and ability-performance correlations are used to demonstrate that an equivalence exists between three broad phases of skill acquisition and three cognitive/intellectual ability determinants of individual differences. Recent extrapolation of the theory to a dynamic representation of abilities is reviewed. Abstracts of scientific publications associated with the research are appended. (Author/TJH)
