Models of duration bisection have focused on the effects of stimulus spacing and stimulus modality. However, interactions between stimulus spacing and stimulus modality have not been examined systematically. Two duration bisection experiments that address this issue are reported. Experiment 1 showed that stimulus spacing influenced the classification of auditory, but not visual, stimuli. Experiment 2 used a wider stimulus range, and showed stimulus spacing effects for both visual and auditory stimuli, although the effects were larger for auditory stimuli. A version of Temporal Range Frequency Theory was applied to the data, and was used to demonstrate that the qualitative pattern of results can be captured with the single assumption that the durations of visual stimuli are less discriminable from one another than are the durations of auditory stimuli.
时长二等分模型主要关注刺激间隔和刺激模态的影响。然而，刺激间隔与刺激模态之间的相互作用尚未得到系统研究。本文报告了两项针对该问题的时长二等分实验。实验1表明，刺激间隔影响听觉刺激的分类，但不影响视觉刺激的分类。实验2采用了更宽的刺激范围，结果表明视觉和听觉刺激均存在刺激间隔效应，不过听觉刺激的效应更大。一种时间范围频率理论版本被应用于这些数据，并用以证明，仅需假设视觉刺激的时长之间相较于听觉刺激的时长之间更难以区分，就能够捕捉到结果的定性模式。
