时距认知分段性指不同长度时距加工机制和表征方式不同。以往研究对1s范围时距认知分段性仍存在分歧,为此在规避以往研究局限基础上设计实验1和实验2。实验1和实验2分别采用双任务范式探讨心算任务对100ms和1000ms听、视时距比较的选择性干扰,结果表明,心算任务影响了1000ms听、视时距比较的75%差别阈限,心算加工负荷越大,75%差别阈限越大,但对100ms听、视时距比较的75%差别阈限没有影响。两项实验支持了1s范围视、听时距认知均具有分段性。
Timing Cognitive Segmentation refers to the different length of time processing mechanism and characterization of different ways. In the past, there were still some differences in the perceived fragmentation of the 1s range, so experiments 1 and 2 were designed on the basis of avoiding the limitations of the previous studies. Experiments 1 and 2, respectively, using dual-task paradigm to discuss the task of mental arithmetic 100ms and 1000ms listening and visual distance compared to the selective interference, the results show that mental arithmetic tasks affect the listening time 1000ms, depending on the time-distance comparison 75% difference threshold, The larger the processing load, the greater the 75% difference threshold, but the 100ms listening, viewing distance compared to 75% of the difference between the threshold has no effect. Two experiments supported the 1s range of vision, listening time interval from the cognitive segmentation.
