Abstract

Recent research exploring perceptual correspondence between and within sensory modalities has demonstrated behavioural advantages when to-be-judged targets are congruent with concurrent distractors (Spence, 2011). This phenomenon holds for a range of perceptual dimensions (e.g. shape- pitch, size-weight, etc). The experiments reported here go beyond current perceptual experience and instead explore the influence these correspondences have on short-term memory. Two experiments tested the idea that congruent dimensions would enhance recognition. In a change detection task participants encoded either six concurrently presented shape-elevation objects (Expt 1: e.g. angular-high, rounded-low), or four sequentially presented pitch-shape pairs (Expt 2: e.g. high-angular, low-rounded). Pairings in both experiments were equally likely to be congruent or incongruent. A single pair was tested after a 2 s delay. For shape-elevation, performance was influenced by the congruence between the elevation of the object and its shape, with congruent pairings enhancing performance significantly with a large effect size. For pitch-shape, change detection was again significant, with congruent pairs enhancing memory. The results imply that congruent correspondences across the perceptual features of an object or event improve memory. This may be the result of attention prioritising congruent pairings, or object-based binding mechanisms dedicated to the typical feature pairings of an object.
