回溯式时距估计的计时机制

Timing mechanism of retrospective duration estimation

回溯式时距估计是以记忆为主要成分,且事后才知要对两个相继事件之间的间隔时间或某一事件持续时间的长短进行估计。可分为近时和远时的回溯式时距估计,两者的计时机制与记忆有关,但各有侧重:前者侧重短时或长时记忆,直接证据来源于即时回忆单一或多个认知任务以估计时间,间接证据则聚焦于物理、生理、心理因素的影响;后者侧重自传体记忆,可从问卷或访谈的测量方式以及主客体特征的影响两个方面来寻找证据。今后需以整合的观点深入探究回溯式时距估计的计时机制,拓展回溯式时距估计行为测量的研究,并开展对回溯式时距估计神经生物学基础的探讨。

Memory is a vital component of retrospective duration estimation, which is either assessed by the interval between two successive events, or the duration of an event after it has ended. Retrospective duration estimation can be divided into two types： close-range and long-distance. The timing mechanisms of both are related to memory; however, they have distinct foci. The former focuses on short-term memory or long-term memory; here, direct evidence is derived from the immediate recall of a single or multiple cognitive tasks to estimate time, while indirect evidence refers to the influence of physical, physiological, and psychological factors. The latter emphasizes the role of autobiographical memory, as evidenced by the measurement mode of a questionnaire or an interview and the influencing factors of subject-object characteristics. Future research should focus on further extending the timing mechanism of retrospective duration estimation in an integrated manner, expand the research of behavioral measurement, and explore the basis of neurobiology for retrospective duration estimation.
