不同感觉通道的节奏感知及其交互作用

节奏感知是人类独有的认知现象, 听觉在节奏加工中具有优势, 声音节奏可以更好地与肢体运动同步, 但视觉和触觉通道在节奏感知上也有着各自特点并存在广泛的交互作用。视觉通道的节奏感知较弱, 与听觉节奏同时呈现时会受到时间定位上的拉扯, 但通过加入运动信息和增强后天经验可以得到强化; 节奏刺激可以调节注意在时间上的分配使其同步化, 这种调节作用可以单通道或者跨通道地出现; 触动觉与听觉联系紧密, 人们可以通过听触通道的整合对节奏进行高级加工。

Rhythm Perception and Interactions between Different Sensory Channels

Rhythm perception is unique to human being. It plays a significant role in our everyday life. Auditory channel is privileged in rhythm processing to other sensation channels which could synchronize the body to a specific rhythm more easily. Meanwhile, visual and haptic senses are also associated with rhythm perception in their own way. There are completed interactions between channels. Rhythm stimulus in vision couldn’t trigger one a feeling of beat as strong as auditory rhythm dose. Vision rhythm perception could be captured in timing by a sound when they are displayed at same time. Visual rhythm could be enhanced when it is with some motion information or by accumulating relevant experience. Rhythm could regulate the time distribution of attention to make the attention synchronized with tempo. The regulation effect could happens in cross-modal way. Haptic sense is deeply connected with auditory sense, the audio-haptic integration could convey advanced rhythm information.
