摘　　要：时距估计是ADHD儿童认知缺陷研究的热点,对于这种现象的原因,以往的研究还没有一致结论。研究采用主观时距与客观时距差异百分比以及时距长度变异值作为反应指标,考查不同时距和通道性质对ADHD儿童时距估计的影响。研究发现ADHD混合型儿童时距估计缺陷受时距长度影响,提示不同时距长度涉及到不同认知加工过程;ADHD儿童时间感缺陷没有通道特异性。Temporal estimation is a hot issue concerning the study of cognitive deficits of children with atten- tion deficit hyperactivity disorder （ADHD）, the cause of which was not found in previous research. This study, by using the percentage difference between subjective interval and objective interval, and the variation value of the length of interval as response indicators, aims to explore the effect of different intervals and channels on ADHD children＇s temporal estimation. The results show that the deficits of ADHD-C children＇s temporal estima- tion are affected by the length of interval, indicating that intervals of different lengths involve different kinds of cognitive processing; the deficits of ADHD children＇ s temporal estimation are not affected by stimulus channels.
