摘　　要：通过视觉刺激方式,对学习障碍学生和普通学生的三种短时距估计进行了比较。结果显示:两组被试对三种时距的估计结果与实际均存在显著差异;在估计结果和相对误差率两方面上,学习障碍学生与普通学生均相似,且两组被试的组内差异也相似。此外,时距2000ms仍是学习障碍学生短时距估计的临界点。这表明,学习障碍学生虽具有视觉认知能力迟缓,但不影响其短时距的估计和临界点。Three short-term distance estimates of students with learning disabilities and ordinary students were compared by visual stimulation. The results showed that there were significant differences between the two groups in the estimation of the three time intervals. In terms of the estimation results and the relative error rate, the students with learning disabilities were similar to the average students, and the two groups were within the group. File differences are similar. In addition, the time interval of 2000ms is still the critical point for short-term distance estimation of students with learning disabilities. This indicates that although students with learning disabilities have a slow visual cognitive ability, they do not affect the estimation and critical point of their shortterm distance.
