ABSTRACT
In this study, we examined the hypothesis that semantic judgment tasks share overlapping processes if they require processing on common dimensions but not if they require processing on orthogonal dimensions in semantic space (Osgood, Suci, & Tannenbaum, 1957). We tested the hypothesis with the implicit association test (IATl Greenwald, McGhee, & Schwartz, 1998) in three experiments. Consistent with the hypothesis, IAT effects (costs in reaction time because of incompatible response mapping between associated judgment tasks) occurred consistently when judgment tasks tapped into common semantic dimensions, whereas no IAT effect appeared when judgment tasks entailed processing on orthogonal semantic dimensions.

In the present study, the specificity of repetition priming between semantic classification tasks was examined using Osgood's (Osgood, Suci, & Tannenbaum, 1957) semantic space as a heuristic for determining the similarity between classifications. The classification tasks involved judging the meaning of words on semantic scales, such as pleasant/unpleasant. The amount of priming across classifications was hypothesized to decrease with increasing distance (decreasing similarity) between semantic scales in connotative semantic space. The results showed maximum repetition priming when the study and the test classifications were the same, intermediate degrees of priming when the study and the test classification scales shared loadings on semantic factors, and little priming when the study and the test classification scales loaded primarily on orthogonal semantic factors--that is, when the distance between scales was maximized. Consistent with the transfer-appropriate processing framework, repetition priming in semantic classifications was highly task specific, decreasing with increasing distance between classification scales.
