The temporal binding window (TBW), which reflects the range of temporal offsets in which audiovisual stimuli are combined to form a singular percept, can be reduced through training. Our research aimed to investigate whether training-induced reductions in TBW size transfer across stimulus intensities. A total of 32 observers performed simultaneity judgements at two visual intensities with a fixed auditory intensity, before and after receiving audiovisual TBW training at just one of these two intensities. We show that training individuals with a high visual intensity reduces the size of the TBW for bright stimuli, but this improvement did not transfer to dim stimuli. The reduction in TBW can be explained by shifts in decision criteria. Those trained with the dim visual stimuli, however, showed no reduction in TBW. Our main finding is that perceptual improvements following training are specific for high-intensity stimuli, potentially highlighting limitations of proposed TBW training procedures.

可以通过训练来减少反映视觉偏移结合了视听刺激的时间偏移范围的时间绑定窗口（TBW）。我们的研究旨在调查刺激强度下训练引起的TBW大小减少是否转移。总共32位观察者在以固定的听觉强度对两种视觉强度进行同步判断之前和之后，仅接受这两种强度之一的视听TBW训练。我们显示，训练具有高视觉强度的人可以减小TBW的大小，以达到明亮刺激，但是这种改善并没有转移到昏暗的刺激上。TBW的减少可以通过决策标准的变化来解释。但是，那些受到昏暗视觉刺激训练的人，其TBW没有降低。我们的主要发现是，训练后的感觉改善是针对高强度刺激的，这可能突出了拟议的TBW训练程序的局限性。
