| Research Abstract |
To investigate a possible locus of multisensory integration between vision and touch, I conducted a series of studies concerning the effects of spatial attention and contextual modulation on the perception of shape information of visual and tactile inputs. The main findings were as follows : (1)The integration process might occur at a stage of object-identification prior to attentional stages of information processing. (2)Contextual effects of flankers on the target detection (i.e., detection of a central Gabor stimulus is modulated by the presence of collinear flanker stimuli) could occur in a cross-modal setting (a central visual target and tactile flankers). In sum, these findings suggest that the integration process could occur at a relatively early perceptual processing stage of perceptual grouping prior to attentional selection.
