MENDONCA, Catarina  y  SANTOS, Jorge A.. A bi-estabilidade nas representações de movimento humano a partir de estímulos visuais e auditivos. Aná. Psicológica [online]. 2010, vol.28, n.2, pp.321-331. ISSN 0870-8231.

There is not enough information about the interactions between visual and auditory stimuli in biological motion perception. Recent data suggests that there might be a brain area (STSp), which responds both to visual and auditory biological motion stimulation. It is also likely that the intermodal processes in biological motion should tend towards greater interaction and integration of stimuli. In this project, we intended to observe the nature of those interactions. To do so, we used strongly biased bistable visual stimuli. We then compared the visual, auditory and audiovisual conditions in two experiments. The results suggest interaction effects between the different stimuli. The audiovisual condition had the best results, both in the bias reduction and in the proportion of correct answers.

Palabras clave : Bias; Biological motion; Bistability; Crossmodal integration; Multimodal perception.
