Time perception, especially duration estimation, plays a crucial role in the organization of behavior across development. Despite its importance, the cognitive mechanisms underlying impaired duration estimation remain insufficiently explored. Recently, the role of cognitive functions, such as executive functions, has been demonstrated in duration estimation. In the present study, the duration estimation, inhibition, shifting, and processing speed performances of participants with idiopathic mild intellectual disability (MID) without associated disorders (N = 79), aged between 10 and 20 years, were compared with those of typical participants (N = 81). The results show that the individuals with MID had difficulties in all cognitive functions (with the exception of one shifting task). Moreover, our results highlight-for the first time-the role of inhibition abilities and processing speed not only in the increase in duration estimation abilities with age, but also in the deficits observed in MID. To conclude, deficits in duration estimation in MID are due to an impairment of other cognitive functions.
时间感知，尤其是时长估计，在整个发育过程中的行为组织中起着至关重要的作用。尽管其很重要，但时长估计受损背后的认知机制仍未得到充分探索。最近，诸如执行功能等认知功能在时长估计中的作用已得到证实。在本研究中，将年龄在10至20岁之间、无相关疾病的特发性轻度智力障碍（MID）参与者（N = 79）的时长估计、抑制、转换和处理速度表现与典型参与者（N = 81）的表现进行了比较。结果表明，MID个体在所有认知功能方面都存在困难（一项转换任务除外）。此外，我们的结果首次强调了抑制能力和处理速度不仅在随着年龄增长时长估计能力增加方面的作用，而且在MID中观察到的缺陷方面的作用。总之，MID中时长估计的缺陷是由于其他认知功能的损害所致。
