Training people on temporal discrimination can substantially improve performance in the trained modality but also in untrained modalities. A pretest-training-posttest design was used to investigate whether consolidation plays a crucial role for training effects within the trained modality and its transfer to another modality. In the pretest, both auditory and visual discrimination performance was assessed. In the training phase, participants performed only the auditory task. After a consolidation interval of either 5 min or 24h, participants were again tested in both the auditory and visual tasks. Irrespective of the consolidation interval, performance improved from the pretest to the posttest in both modalities. Most importantly, the training effect for the trained auditory modality was independent of the consolidation interval whereas the transfer effect to the visual modality was larger after 24h than after 5 min. This finding shows that transfer effects benefit from extended consolidation.
对人们进行时间辨别训练可以显著提高在训练模态下的表现，而且在未训练的模态下也能提高表现。采用前测-训练-后测设计来研究巩固是否对训练模态内的训练效果及其向另一模态的迁移起着关键作用。在前测中，评估了听觉和视觉辨别表现。在训练阶段，参与者只执行听觉任务。在5分钟或24小时的巩固间隔后，参与者再次接受听觉和视觉任务测试。无论巩固间隔如何，两种模态下的表现从前测到后测都有所提高。最重要的是，训练模态（听觉）的训练效果与巩固间隔无关，而向视觉模态的迁移效果在24小时后比5分钟后更大。这一发现表明，迁移效果受益于延长的巩固时间。
