一些实验表明，检测、信号能量和感知音调强度之间的关系与检测、信号能量和感知音调持续时间之间的关系非常不同。我们提出了一项新任务，即幅度估计和检测（MED）任务，它允许人们评估刺激和检测的心理维度之间的关系。在实验 1 中，我们使用 MED 任务来评估感知音调强度与是/否任务中的检测之间的关系。数据显示两者之间存在很强的相关性。在实验 2 中，我们使用 MED 任务来评估感知音调持续时间与是/否任务中的检测之间的关系。数据显示两者之间的关系相对较弱。我们的数据表明，与音调持续时间相比，音调强度是一个感知噪音较小的维度。我们介绍了 MED 任务的优点和缺点，希望该任务可以帮助研究人员更好地理解各种认知过程背后的感知和决策机制。
Several experiments suggest that the relation between detection, signal energy, and perceived tone intensity is very different hom the relation between detection, signal energy, and perceived tone duration. We propose a new task, the magnitude estimation and detection (MED) task, that allows one to assess the relation between the psychological dimensions of a stimulus and detection. In Experiment 1, we used the MED task to assess the relation between perceived tone intensity and detection in a yes/no task. The data show a strong relation between the two. In Experiment 2, we used the MED task to assess the relation between perceived tone duration and detection in a yes/no task. The data show a relatively weak relation between the two. Our data suggest that tone intensity is a less perceptually noisy dimension than tone duration, We present the advantages and disadvantages of the MED task with the hope that this task can aid researchers in better understanding the perceptual and decisional mechanisms underlying various cognitive processes.
