Abstract

Behavioral benefits have been recently evidenced via multisensory integration process. Reaction times, detection or synchronization performances could be made more efficient by a bimodal stimulation than by its unimodal components. We questioned about the generalization of such results on a more challenging behavioral task. We used a well-known bimanual coordination task in which participants have to synchronize with audio, tactile or audio-tactile metronomes. Results show that according to the intrinsic parameters of the metronome, audio-tactile events could lead to higher coordination performance scores than its corresponding unimodal components.

2. Audio-tactile events can improve the interlimb coordination in Juggling

Abstract

Elementary reactive behavior can be improved in the case of cross-modal sensory interactions thanks to underlying multisensory integration mechanisms. Can this benefit be generalized to a challenging ongoing perceptive-motor performance? We choose a juggling task to examine this question. A central issue wellknown in juggling lies in establishing and maintaining a specific temporal coordination among balls, hands, eyes and posture. Here, we tested whether providing additional timing information about the balls and hands motions by using external sound and tactile periodic stimulations improved the performance of jugglers. Results indicated that specific combination of auditory and tactile metronome led to a decrease of the spatiotemporal variability of the juggler’s performance. A contrario, degraded performances were obtained in the case of unimodal tactile metronome. We discuss these results in view of the understanding of the neuronal integration process implied in the audio-tactile interaction, and considering the well-known gating effect of movement on vibrotactile perception.

26. CAN DIFFERENT LEVELS OF S-R PRACTICE INFLUENCE SEQUENCE LEARNING? AN INVESTIGATION INTO THE CONTEXT OF A PERCEPTUAL-MOTOR SEQUENCE LEARNING TASK

Abstract

The main aim of the present study was to evaluate on a serial reaction time task the effect of stimulus-response (S-R) practice on sequence learning. The experiment used a pointing task which allowed recording reaction times and movement times. The basic manipulation consisted in varying the amount of S-R practice prior to sequence practice. Two main findings from this study may be highlighted. Firstly, the benefit from extensive S-R practice was mainly observed in the random practice phase. Secondly, S-R learning and sequence learning were reflected by different components of performance. The movement times were selectively sensitive to the acquisition of S-R regularities whereas the reaction times were selectively sensitive to the acquisition of sequence regularities. The implications of these results on the comprehension of the sequence learning mechanism were then discussed.
