Twenty children from regular classrooms and 20 children from self-contained, learning disability classrooms tracked four different acoustic stimuli through three fixed paths in space. An apparatus specifically designed to provide objective data on accuracy of tracking was used. The results showed that learning disability children as a group were inferior in their abilities to follow a moving speech signal and a moving white noise. The position of the target with respect to the listeners' midlines affected accuracy of tracking, but this was not a function of the hand used to control the pointer.
来自普通教室的20名儿童和来自独立的学习障碍教室的20名儿童，在空间中通过三条固定路径追踪四种不同的声学刺激。使用了一种专门设计用于提供追踪准确性客观数据的仪器。结果表明，作为一个群体，学习障碍儿童在跟随移动语音信号和移动白噪声方面的能力较差。目标相对于听众中线的位置会影响追踪的准确性，但这与用于控制指针的手无关。
