本研究采用知觉学习的方法，研究了持续时间辨别任务中的潜在迁移效应。受试者被训练区分两个空的时间间隔标记的听觉哔哔声，使用两个替代的被迫选择范例。主要目的是检验知觉学习是否会推广到具有相同持续时间但由视觉闪光标记的空间隔。该实验还包括标记有听觉蜂鸣声的较长间隔，以及与训练间隔相同持续时间的填充听觉间隔，以检查感知学习是否会在相同的感觉模态中推广到这些条件。与以前的研究结果显示从触觉到听觉模态的转移相反，目前的结果并不表明从听觉模态到视觉模态的转移，但它们确实显示了听觉模态内的转移。
Perceptual learning was used to study potential transfer effects in a duration discrimination task. Subjects were trained to discriminate between two empty temporal intervals marked with auditory beeps, using a two-alternative forced choice paradigm. The major goal was to examine whether perceptual learning would generalize to empty intervals that have the same duration but are marked by visual flashes. The experiment also included longer intervals marked with auditory beeps and filled auditory intervals of the same duration as the trained interval, in order to examine whether perceptual learning would generalize to these conditions within the same sensory modality. In contrast to previous findings showing a transfer from the haptic to the auditory modality, the present results do not indicate a transfer from the auditor), to the visual modality; but they do show transfers within the auditory modality.
