Abstract
Unimodal and cross-modal information provided by faces and voices contribute to identity percepts. To examine how these sources of information interact, we devised a novel audiovisual sorting task in which participants were required to group video-only and audio-only clips into two identities. In a series of three experiments, we show that unimodal face and voice sorting were more accurate than cross-modal sorting accuracy: While face sorting was consistently most accurate followed by voice sorting, cross-modal sorting was at chancel-level or below. In Experiment 1, we compared performance in our novel audiovisual sorting task to a traditional identity matching task, showing that unimodal and cross-modal identity perception were overall moderately more accurate the traditional identity matching task. In Experiment 2, separating unimodal from cross-modal sorting led to small improvements in accuracy for unimodal sorting, but no change in cross-modal sorting performance. In Experiment 3 we explored the effect of minimal audiovisual training: Participants were shown a clip of the two identities in conversation prior to completing the sorting task. This led to small, non-significant improvements in accuracy for unimodal and cross-modal sorting. Our results indicate that unfamiliar face and voice perception operate relatively independently with no evidence of mutual benefit, suggesting that extracting reliable cross-modal identity information is challenging.
