当刺激同时呈现在听觉和触觉通道中时，以及当刺激单独呈现在其中一种通道中时，受试者被要求执行知觉任务。结果表明，当对认知过程的要求较小时，同时呈现的听觉和触觉刺激可以被加工，以及当刺激只以一种形式呈现时。在一项需要大量认知处理的任务中，受试者很难在两种模式下保持高水平的表现，注意力的分配成为表现的重要决定因素。这些数据与一种理论相一致，即当受试者难以同时执行两项知觉任务时，认知而不是知觉的处理会中断。
Subjects were required to perform perceptual tasks when stimuli were presented simultaneously in the auditory and tactile modalities and when they were presented in one of the modalities alone. The results indicated that when the demands on cognitive processes are small, auditory and tactile stimuli presented simultaneously can be processed as well as when stimuli are presented in only one modality. In a task which required a large amount of cognitive processing, it became difficult for subjects to maintain high levels of performance in both modalities and the distribution of attention became an important determinant of performance. The data were consistent with a theory that cognitive, but not perceptual, processing is disrupted when subjects have difficulty performing two perceptual tasks simultaneously.
