Abstract
Abstract Three experiments explored concreteness effects in memory for words following imagery-related orienting tasks. Predictions from dual coding and relational-distinctive explanations of concreteness and imagery effects were contrasted. Of particular interest were differences in the magnitudes of concreteness effects in an item-specific imagery task (timed image generation) and a relational imagery task (rating of relative imageability). The effects of restricted-range (high and medium-imagery) versus full-range (high, medium and low-imagery) materials were also considered as a means to evaluate the effects of relative item distinctiveness on concreteness effects. The results demonstrated the importance of relational information in the production of concreteness effects and indicated that imagery alone is an insufficient explanation of concreteness effects. At the same time, they revealed the need for a more comprehensive theoretical account of the role of mental imagery in memory, as neither model u...
