THE RELATIONSHIPS BETWEEN PSYCHOMETRIC INTELLIGENCE AND LEARNING IN AN EXPLICIT AND AN IMPLICIT TASK

An experiment is reported examining the relation of implicit grammar l earning and series completion tasks to a standard measure of psychomet ric intelligence, the Wechsler Adult Intelligence Scale-Revised (WAIS- R; D. Wechsler, 1981). The results replicate and extend an earlier stu dy by A. S. Reber, F. F. Walkenfeld, and R. Hernstadt (1991) and provi de the following support for the differences between explicit and impl icit tasks: (a) The implicit task was less strongly related to Full Sc ale IQ, and (b) the implicit task appeared to be independent of age. T he implicit and explicit tasks exhibited a quite different pattern of relations to the factors known to underlie WAIS-R performance. Althoug h both tasks showed significant links with a Perceptual Organization f actor, only the series completion task showed a significant link with the Attention factor.
