毫秒到秒范围内的时间判断取决于对时间的持续关注和强大的工作记忆表征。工作记忆容量（WMC）的个体差异预测了广泛的高阶和低阶认知能力。在目前的工作中，我们研究了WMC是否会预测时间歧视。高WMC的个人比低WMC更敏感，在区分较长的两个时间间隔在一系列的时间差异。通过将液体智力指标作为协变量，并不能消除与WMC相关的时间辨别力的个体差异。结果进行了讨论，在注意力，工作记忆和其他心理结构。
Temporal judgment in the milliseconds-to-seconds range depends on consistent attention to time and robust working memory representation. Individual differences in working memory capacity (WMC) predict a wide range of higher-order and lower-order cognitive abilities. In the present work we examined whether WMC would predict temporal discrimination. High-WMC individuals were more sensitive than low-WMC at discriminating the longer of two temporal intervals across a range of temporal differences. WMC-related individual differences in temporal discrimination were not eliminated by including a measure of fluid intelligence as a covariate. Results are discussed in terms of attention, working memory and other psychological constructs.
