Intensity resolution of pure tones in a one-interval forced-choice paradigm was measured for experienced musicians under fixed- and uncertain-frequency conditions, and under uncertain-frequency conditions with informative cues as to target frequency. The uncertain frequency effect for intensity resolution, when present, was reduced or removed by frequency cueing, both with auditory stimulus cues and with visually presented information cues. Also, intensity resolution performance improved over the course of the experiment, both for fixed- and for uncertain-frequency conditions, as had been found previously. Analysis of the individual data indicated that across-experiment learning was unrelated to the ability to use the auditory stimulus cue, and that multiple-band learning was incompatible with the use of the visual information cue. The results are consistent with the idea that the single-band listening observed in fixed-frequency conditions was induced in most listeners by the auditory stimulus cue, but that some listeners chose to use the visual information cue to single-band listen while others ignored it and used multiple-band listening in that condition.
在单区间强迫选择范式中，对经验丰富的音乐家在固定频率和不确定频率条件下，以及在具有目标频率信息线索的不确定频率条件下，测量了纯音的强度分辨率。当存在强度分辨率的不确定频率效应时，通过频率提示（包括听觉刺激提示和视觉呈现的信息提示）可减少或消除该效应。此外，与之前的发现一样，在固定频率和不确定频率条件下，强度分辨率表现均在实验过程中得到改善。对个体数据的分析表明，跨实验学习与使用听觉刺激提示的能力无关，并且多频段学习与使用视觉信息提示不兼容。结果与以下观点一致：在固定频率条件下观察到的单频段聆听在大多数听众中是由听觉刺激提示诱发的，但在该条件下，一些听众选择使用视觉信息提示进行单频段聆听，而另一些听众则忽略它并使用多频段聆听。
