Abstract

To examine hemispheric differences in accessing a mental representation that embodies perceptual elements and their spatial relationships (i.e., perceptual elaboration and integration), we developed a cross-modal perceptual elaboration paradigm (PEP) in which an imagined percept, rather than a propositional concept, determined congruency. Three target image conditions allow researchers to test which mental representation is primarily accessed when the target is laterally presented. For example, the “Integrated” condition is congruent with either propositional or perceptual mental representations; therefore, results from both hemifield conditions (RVF/LH vs. LVF/RH) should be comparable. Similarly, the “Unrelated” condition is incongruent with either propositional or perceptual mental representations; therefore, results from both hemifield conditions should be comparable as well. However, the “Unintegrated” condition is congruent with the propositional mental representation but not the perceptual mental representation. Should either hemisphere access one representation initially, differences will be revealed in either behavioural or electroencephalography results.

This paradigm:

• is distinct from existing paired paradigms that emphasize semantic associations.

• is important given increasing evidence that discourse comprehension involves accessing perceptual information.

• allows researchers to examine the extent to which a mental representation of discourse can embody perceptual elaboration and integration.
