Audio-visual integration in perceiving the size of objects : Where is the object size measured?

为了研究听觉信息在感知物体大小方面的影响，研究人员向人类参与者呈现了视听刺激，其中模拟球在地面上跳跃的运动图像与球粉碎的声音相结合。这项任务是评估被感知物体的“视觉”大小。虽然任务是视觉的，实验情境包含的视觉信息多于听觉信息，但我们清楚地观察到，知觉评价受到听觉刺激尺度的系统影响。

To investigate effects of auditory information in perceiving object size, audio-visual stimuli where motion pictures simulating a ball to bound on a ground is combined with a sound of ball smashing were presented to human participants. The task was to evaluate the "visual" size of the perceived object. Although the task was visual and the experimental situation contained more visual informations than auditory informations, it was clearly observed that the perceptual evaluation was systematically influenced by the scaling of the auditory stimuli.
