时距认知的年龄差异

年龄是影响时距认知的一个重要因素.基于时间认知的信息加工模型,通过对时距估计和时距辨别两种任务条件下的有关年龄差异研究的回顾,发现虽然相关的研究结果没有确定的结论,但年老被试在时距加工的准确性和变异性上与年轻被试存在显著的差异.由于研究中所采用的时距长度、任务不同,内部时钟频率、注意和记忆都可能导致时距认知上的年龄差异.现代脑成像技术可为研究时距认知年龄差异的机制提供有效的手段.

The Age-Related Difference of Time Cognition:A Review

Age is a very important factor in the research of time cognition.Based on time information processing model,we have made a literature review on age-related difference of time estimation.Although the findings have not been extensively conclusive,it confirmed the effects of aging on time estimation.Compared with younger adults,older adults' time estimation is more variable and less accurate.This suggests that the specific findings are critically dependent on the type and design of the study and the methodology employed.
