【摘要】：警觉和时间知觉对人们良好的适应周围环境具有重要意义。然而,警觉是否会影响时间知觉以及影响的机制却少有研究。我们通过两个实验分别探讨了警觉信号在视觉和听觉时间信息加工过程中的作用。实验一发现警觉信号使被试高估了视时距,但不影响被试的视时间知觉的敏感性;实验二发现警觉信号不但使被试高估了听时距,也增强了被试听时间知觉的敏感性。结果说明,警觉信号可能是通过调节选择性注意进而改变开关的潜伏期来影响视时间知觉,对听时间知觉的影响可能是通过调节唤醒和选择性注意进而提高起搏器的节律和改变开关的潜伏期来实现的。
[Abstract]:Alertness and time perception are important for people to adapt to their surroundings. However, little research has been done on whether alertness affects time perception and its mechanism. Two experiments were conducted to investigate the role of alert signals in the processing of visual and auditory time information. Experiment 1 found that the alert signal overestimated the visual time distance, but did not affect the sensitivity of the subjects' perception of visual time, and the second experiment found that the alert signal not only overestimated the hearing time distance, but also enhanced the sensitivity of the hearing time perception. The results suggest that the alert signal may affect visual time perception by regulating selective attention and changing the latency of the switch. The effect on the perception of auditory time may be achieved by adjusting the arousal and selective attention, thus increasing the rhythm of the pacemaker and changing the latency of the switch.
