摘　　要：采用时距二分任务,探讨聋生在视觉通道的1s以下和1s以上时距知觉的特点。结果发现,在1s以下条件下,聋生时距判断准确性低于普通学生;聋生CNV峰值与LPCt波幅低于普通学生,CNV潜伏期短于普通学生,LPCt峰值潜伏期长于普通学生。在1s以上条件下,聋生时距判断准确性高于普通学生;聋生N1、P2、CNV与LPCt成分各项指标与普通学生均没有显著差异。这说明,听觉丧失损伤了聋生1s以下的时距记忆与决策过程,支持了普遍缺陷假设;但听觉丧失未对聋生1s以上时距加工产生显著影响,支持了感觉补偿机制。因此,时距长度在听觉丧失对视觉时距知觉的影响中具有调节作用,为时间认知的分段综合模型提供了新的支持证据。Using a duration bisection task, the characteristics of sub-second and supra-second duration perception in the visual channel among deaf students were explored. The results showed that under the sub-second condition, the duration judgment accuracy of deaf students was lower than that of non-deaf students;The CNV peak and LPCt amplitude of deaf students were lower than those of non-deaf ones, the CNV latency of deaf students was shorter than that of non-deaf ones, and the latency of LPCt peak was longer than that of non-deaf ones. Under the supra-second condition, the duration judgment accuracy of deaf students was higher than that of non-deaf students;There were no significant differences in N1, P2, CNV, and LPCt components between deaf students and non-deaf students. These results indicated that hearing loss might have impaired the sub-second duration memory and decision-making processes of deaf students, which supported the generalized-deficiency hypothesis. However, hearing loss did not affect the processing of supra-second duration perception. This research supported the sensory compensation mechanism. Therefore, duration length played a regulatory role in the effect of hearing loss on visual duration perception. This research provided new evidence for the range-synthetic model of temporal cognition.
