| 摘 要： | 时间知觉阈限并非单个概念，而是依赖于不同判断标准在不同时间经验问的分层级的门槛，并可能对应着不同时距范围内时间信息加工的不同机制。研究用分视野呈现技术考察了大脑两半球在三种不同反应标准下测定的短时距刺激时间知觉阈限上的差异，结果表明：（1）三种反应标准和不同呈现方位条件下，极限法测定的时间知觉阈限存在显著差异，二因素的交互作用不显著；（2）就时间知觉阈限而言，左半球存在着时间信息加工上的相对优势；（3）“同时-非同时”的阈限最低，其次是“连续-分离”的阈限，最后是“先后顺序”的阈限。

| Abstract: | The threshold of temporal perception is not a single conception but a graded separating point existing in different phases of time experience, which depends on different estimation criteria. This hierarchical threshold may also reflect the corresponding temporal information processing mechanisms in different time intervals. This research, which employed divided visual field technique, was supposed to explore the differences of temporal perceptual thresholds in the cerebral hemispheres, measured with three different reaction standard. The results showed that： （1） under different conditions in terms of reaction standard and display condition, the temporal perceptual threshold shows obvious difference. However, no significant interaction between the two factors is shown; （2）as far as the temporal perceptual threshold is concerned, the left-hemisphere is superior in temporal information processing; （3） the threshold with the reaction standard of simultaneity vs nonsimultaneity is lower than it is with the reaction standard of continuity vs successiveness, which is even lower than that with the standard of order. |
