响度感知的重新校准是指对不同声音频率的听觉信号的相对响应性的类似适应的变化。在一个频率上聆听相对较弱的音调，在另一个频率上聆听较强的音调，会使后者显得更柔和。作者不仅展示了响度大小估计的重新校准，还展示了简单响应时间 (RT) 和选择 RT 的重新校准。 RT 取决于声音强度，可以作为响度的替代值。最重要的是，快速分类范式还提供了错误测量。 RT 和误差可以共同区分灵敏度的变化和响应标准的变化。在不同的重新校准条件下选择 RT 的变化并不伴随着速度-准确度权衡所预测的错误率的变化。这些结果支持了这样的假设：响度重新校准不是由决策标准变化引起的，而是反映了听觉强度的基本表示的变化。
Recalibration in loudness perception refers to an adaptation-like change in relative responsiveness to auditory signals of different sound frequencies. Listening to relatively weak tones at one frequency and stronger tones at another makes the latter appear softer. The authors showed recalibration not only in magnitude estimates of loudness but also in simple response times (RTs) and choice RTs. RTs depend on sound intensity and may serve as surrogates for loudness. Most important, the speeded classification paradigm also provided measures of errors. RTs and errors can serve jointly to distinguish changes in sensitivity from changes in response criterion. The changes in choice RT under different recalibrating conditions were not accompanied by changes in error rates predicted by the speed-accuracy trade-off. These results lend support to the hypothesis that loudness recalibration does not result from shifting decisional criteria but instead reflects a change in the underlying representation of auditory intensity.
