摘　　要：时距估计的长度效应,是指不同长度的时距存在不同的加工机制。从行为反应、神经心理以及脑成像三个领域对有关长度效应的研究进行综述。行为实验多用双任务范式,考察涉及工作记忆的非时间任务对长短时距加工的影响,行为实验的结果不一致,采用双任务范式的实验证据一般不能证明长度效应的存在。而有关脑机制的神经心理与脑成像研究结果一致,支持存在长度效应,但对于两个计时机制各自涉及的脑区以及脑电活动模式仍没有定论。长短时距可能因为所用任务特征不同采用不同计时机制,今后的研究将重点探讨特定任务是否涉及不同的计时机制。Length effect in duration estimation means that sub- and supra-second interval have distinct mechanisms. Several researchers have carried out lots of experiments to test the separate-mechanism hypothesis. The result of behavioral research is mixed. Some argues against the distinct hypothesis. Experiments with dual-task paradigm have discovered that cognitive factors have similarly influenced both sub- and supra-second intervals. But the result of neuropsychological research and brain imaging research support the distinct hypothesis. Brain areas and brain activation patterns during measurement of sub- and supra-second intervals are still being discussed. Future goal in the study is to determine which timing systems will be used under which specific circumstances.
