Lewis, Christopher (2010). The Influence of Voice Gender on the Perceived Sex of Biological Motion. (Mentor: E. Hiris)
Integrating information from multiple modalities allows us to live in an environment without being constantly confronted with perceptual ambiguity. I studied how visual and auditory information is integrated in making judgments about sex. Observers were shown a series of point-light walkers (PLWs) which each varied in the gender information they contained. Presenting those stimuli with unambiguous male, female, and neutral gender voices, each of which either addressed the stimuli or created the perception of being from the stimuli, had no effect on the visually perceived gender if the voice addressed the stimuli. However, when the voice was coming from the stimuli, the gender information carried by the voicer influenced the visually perceived gender. These data suggest auditory sex cues influenced the perceived sex of biological motion, but only when the voice was coming from the biological motion. Thus, audiovisual integration of biological motion is processed at a level that can differentiate if the auditory information is related to the visual stimuli.
