Abstract

This paper discussed two logics for demonstrating implicit memory and the problem of conscious and unconscious influences within a task. The logic of indirect demonstration was used in functional dissociation experiments, the prerequisite of which was a "pure" assumption of conscious or unconscious influence in a test. The logic of direct demonstration was used in the matched comparison experiments, the prerequisite of which was that both conscious and unconscious influences, were engaged in a test. A process-dissociation procedure was proposed based on the latter by Jacoby, however, it separated conscious and unconscious influences within a test by borrowing computations from the classic test theory. The author argued that a revised equation for inclusion test should be generated, that is, Inclusion = R(1-a) + A(1-R) ,thus the PDP should be revised that includes four equations. It not only considered a failure of unconscious influences (1-a) in the inclusion test that the PDP omitted, but also provided more accurate estimation of recollection (R) than that of the recollection (R₀) from the PDP, which had a theoretical basis of mathematics.
