title: The role of consolidation for perceptual learning in temporal discrimination within and across modalities.
abstract: 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.
