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 auditory to the visual modality; but they do show transfers within the auditory modality.
知觉学习被用于研究持续时间辨别任务中的潜在迁移效应。使用二选一强制选择范式，训练受试者区分两个由听觉哔哔声标记的空时间间隔。主要目标是检验知觉学习是否能推广到具有相同持续时间但由视觉闪光标记的空时间间隔。该实验还包括由听觉哔哔声标记的更长间隔以及与训练间隔持续时间相同的有声音的听觉间隔，以便检验知觉学习是否能在同一感觉通道内推广到这些条件。与先前显示从触觉通道到听觉通道有迁移的研究结果相反，目前的结果并未表明从听觉通道到视觉通道有迁移；但它们确实显示了在听觉通道内的迁移。
