在新生鸡中评价了前刺激活动水平对听觉反应性的影响。偷窥率被用来作为刺激前活动的措施，并在其他正在进行的发声的延迟被用来作为反应的措施。结果表明，增加反应纯音在中间水平的prestimulus活动。在高活动和低活动期间，反应性降低。在刺激之前，这种效应最强。类似的分析在其他研究中也是有用的，这些研究依赖于重复反应的变化率，比如全身运动、头部转动、心率，也许还有神经电位。年轻受试者的反应中的一些可变性可以通过测量受试者在刺激出现时的活动来控制。
The effects of prestimulus activity levels on auditory responsiveness were evaluated in newborn chickens. Rates of peeping were used as measures of prestimulus activity, and delays in the otherwise ongoing vocalizations were used as measures of responsiveness. Results show increased responsiveness to pure tones at intermediate levels of prestimulus activity. Responsiveness is reduced during periods of high and low activity. The effect is strongest just prior to the stimulus. Similar analyses could be useful in other studies that depend on the changing rate of repetitive responses, such as gross body movements, head turning, heart rate, and perhaps neural potentials. Some of the variability in the responses of young subjects can be controlled by measuring the subject's activity at the time a stimulus is presented.
