大多数关于听觉信息的作用及其与视觉的相互作用的研究都集中在感知性能上。声音线索对视觉引导的手部运动的影响知之甚少。我们记录了手指在接触时产生的声音，因为参与者抓住了覆盖有不同材料的刺激物。然后，在进一步的会话中，在朝向刺激对象的伸手抓握运动开始之前或之后，通过耳机将预先记录的接触声音传递给参与者。在以下条件下测量到达抓握运动学：（i）一致，其中呈现的接触声音和由待抓握刺激引起的接触声音对应;（ii）不一致，其中呈现的接触声音不同于接触时刺激产生的声音;（iii）控制，其中呈现与真实的事件无关的合成声音。促进效应一致的试验中发现，干扰效应不一致的试验中发现。在第二个实验中，刺激物的上部和下部被不同的材料覆盖。呈现的声音总是与覆盖刺激的上半部分或下半部分的材料一致。参与者始终将手指放在与所呈现的接触声音相对应的刺激的一半上。总之，这些研究结果提供了一个实质性的贡献，目前的辩论类型的对象表示引起的听觉刺激和多感官性质的感觉运动转换的基础行动。
Most research on the roles of auditory information and its interaction with vision has focused on perceptual performance. Little is known on the effects of sound cues on visually-guided hand movements. We recorded the sound produced by the fingers upon contact as participants grasped stimulus objects which were covered with different materials. Then, in a further session the pre-recorded contact sounds were delivered to participants via headphones before or following the initiation of reach-to-grasp movements towards the stimulus objects. Reach-to-grasp movement kinematics were measured under the following conditions: (i) congruent, in which the presented contact sound and the contact sound elicited by the to-be-grasped stimulus corresponded; (ii) incongruent, in which the presented contact sound was different to that generated by the stimulus upon contact; (iii) control, in which a synthetic sound, not associated with a real event, was presented. Facilitation effects were found for congruent trials; interference effects were found for incongruent trials. In a second experiment, the upper and the lower parts of the stimulus were covered with different materials. The presented sound was always congruent with the material covering either the upper or the lower half of the stimulus. Participants consistently placed their fingers on the half of the stimulus that corresponded to the presented contact sound. Altogether these findings offer a substantial contribution to the current debate about the type of object representations elicited by auditory stimuli and on the multisensory nature of the sensorimotor transformations underlying action.
