本实验采用视觉和听觉刺激为200-800ms的一分为二任务，考察了通道对5岁、8岁儿童和成人时间分辨的影响。在第一次会议中，参与者被要求将刺激持续时间与同一模式(模式内会议)和第二次会议中不同模式(跨模式会议)中提出的标准持续时间进行比较。心理物理功能在所有年龄组中都是有序的，长反应的比例(判断一个持续时间更接近于长反应而不是短反应标准)随着刺激持续时间的延长而增加，尽管5岁儿童的功能比8岁儿童和成年人更平坦。在所有年龄组中，听觉刺激都比视觉刺激长。统计结果和理论模型表明，这种通道效应是由于内部时钟起搏速度的差异所致。5岁的孩子也认为视觉刺激比听觉刺激更易变，这表明他们在视觉通道中的时间敏感性低于在听觉通道中的时间敏感性。
This experiment investigated the effect of modality on temporal discrimination in children aged 5 and 8 years and adults using a bisection task with visual and auditory stimuli ranging from 200 to 800 ms. In the first session, participants were required to compare stimulus durations with standard durations presented in the same modality (within-modality session), and in the second session in different modalities (cross-modal session). Psychophysical functions were orderly in all age groups, with the proportion of long responses (judgement that a duration was more similar to the long than to the short standard) increasing with the stimulus duration, although functions were flatter in the 5-year-olds than in the 8-year-olds and adults. Auditory stimuli were judged to be longer than visual stimuli in all age groups. The statistical results and a theoretical model suggested that this modality effect was due to differences in the pacemaker speed of the internal clock. The 5-year-olds also judged visual stimuli as more variable than auditory ones, indicating that their temporal sensitivity was lower in the visual than in the auditory modality.
