Processing of covariation (among features) present in stimulus material was investigated. Subjects were unable to articulate the manipulated covariation between verbally described psychological characteristics and appearance of a set of stimulus persons. Based on the two-stage question answering model (Glucksberg Reber Reber Gordon & Holyoak, 1983). The research on implicit learning raises the question as to what kind of formal aspect or hidden structure contained in stimulus material is subject to such processing without a perceiver's being able to articulate what in particular is being processed. Recent research by Lewicki (1982, in press) suggests that one of these formal aspects might be the covariation among events
Pawel Lewicki (Wed,) studied this question.
