Abstract

Effects of cross-modal information on representational momentum and on representationalgravity were examined. In Experiment 1, ascending or descending visual motion (changinglocation) was paired with ascending or descending auditory motion (changing frequency);motion was congruent (both ascending, both descending) or incongruent (one ascending, onedescending). Memory for visual location or auditory pitch was probed. Congruency resultedin larger forward displacement for auditory pitch, but did not influence forward displacementfor visual location. In Experiment 2, leftward or rightward visual motion was paired withascending, descending, or no auditory motion. Memory for visual location was displaceddownward with descending or no auditory motion, and downward displacement was largerfor visual motion paired with descending auditory motion than for visual motion paired withascending auditory motion. Effects of cross-modal information on displacement suggestrepresentational momentum and representational gravity reflect high-level processing.
