在两个实验中，水平方向和垂直方向的声音呈抛物线移动。参与者必须触摸屏幕，以指示虚拟移动球将在何时何地越过一条可见线。我们预测，由于听觉系统对时间信息的敏感性，对音高的操纵应该对时间误差的影响大于空间误差。刺激是通过安装在触摸屏周围的扬声器产生的沿着抛物线移动的五种不同音高的声源。结果表明，俯仰对水平方向抛物线的空间常数和空间变量误差有影响（实验1），对垂直方向抛物线的时间常数误差有影响（实验2）。我们得出结论，截球任务的时间和空间精度受到音调操纵的不同影响，这需要在未来的研究中考虑听觉信息对捕捉虚拟移动球的影响。
In two experiments, horizontal and vertical orientated sounds moved in parabolas. Participants had to touch a screen to indicate where and when a virtual moving ball would cross a visible line. We predicted that due to the sensitivity of the auditory system to temporal information, manipulations of pitch should affect temporal errors more than spatial errors. Stimuli were sound sources at five different pitches moving along a parabola produced through loudspeakers mounted around a touch screen. Results showed pitch effects on spatial constant and spatial variable errors when the parabola was horizontally oriented (Exp. 1), and on temporal constant errors in vertically oriented parabolas (Exp. 2). We conclude that temporal and spatial precision in interception tasks were affected differently by pitch manipulations and require consideration in future studies when assessing the impact of auditory information on catching virtually moving balls.
