在四个实验中，增加相关和不相关的听觉刺激的强度被发现在简单的，去/不去，和选择反应时间（RT）任务中增加反应力（RF）。这些结果提出了问题的模型，本地化的听觉强度对纯粹的感知过程的影响，而不是强度也影响运动输出过程在许多情况下。在实验1中，简单RT，去/不去，选择RT任务进行了比较，使用相同的刺激，所有的任务。听觉刺激强度影响RT和RF，这些影响不调制的任务。在实验2-4中，一个无关的听觉辅助刺激伴随着相关的视觉刺激，和去/不去和选择任务。不相关的听觉辅助刺激的强度被发现会影响RT和RF，虽然这些影响的大小在一定程度上取决于辅助刺激的时间可预测性。
In four experiments, increasing the intensities of both relevant and irrelevant auditory stimuli was found to increase response force (RF) in simple, go/no-go, and choice reaction time (RT) tasks. These results raise problems for models that localize the effects of auditory intensity on purely perceptual processes, indicating instead that intensity also affects motor output processes under many circumstances. In Experiment 1, simple RT, go/no-go, and choice RT tasks were compared, using the same stimuli for all tasks. Auditory stimulus intensity affected both RT and RF, and these effects were not modulated by task. In Experiments 2-4, an irrelevant auditory accessory stimulus accompanied a relevant visual stimulus, and the go/no-go and choice tasks were used. The intensity of the irrelevant auditory accessory stimulus was found to affect RT and RF, although the sizes of these effects depended somewhat on the temporal predictability of the accessory stimulus.
