This paper examines the contrasting predictions of the dual-coding and depth-of-processing theories and proposes a resolution of their differences in a more generic two factor model of stimulus trace elaboration. First, the author conducts an analysis of the literature relevant to the two approaches, reviewing three major studies and finding their results inconclusive. Second, he conducts a theoretical analysis of the two positions, contrasting the memory structures and processes they propose and finding few significant differences. Third, he describes a generic two factor stimulus trace elaboration model to more adequately address the variables currently described and explained by the dual and depth theories. The author reviews five additional studies in support of the two factor model. / The characteristics of the two factor model of stimulus trace elaboration are then explored in a 2 x 4 factorial study, involving the free recall and recognition of picture and word stimulus items under four learning strategies: Control, within-item processing, between-item processing, and a mixture of within-item and between-item processing. Separate analyses of variance were performed on the recognition and recall tests. / The results of the study are as follows. First, pictures and words failed to elicit different retention scores, under either the recognition or recall conditions. This finding is inconsistent with both the dual-coding and depth-of-processing positions, but entirely consistent with stimulus trace elaboration theory. Second, there were no differences in the performance of the within-item processing, between-item processing, and mixture groups on the recognition test, although all three surpassed the control group. This finding is entirely consistent with the one factor model of stimulus trace elaboration. Third, there were no differences between the mixture and between-item processing groups, although these groups surpassed both the within-item processing and control conditions, which again were not significantly different from one another. This finding is partially consistent with the two factor model of stimulus trace elaboration. This research provides strong support for the stimulus trace elaboration theory, but only weak support for a two factor variant of that theory. / Source: Dissertation Abstracts International, Volume: 43-02, Section: A, page: 0400. / Thesis (Ph.D.)--The Florida State University, 1982.
