The acquisition of information on the timing of events or actions (temporal learning) occurs in both the subsecond and suprasecond range. However, although relevant differences between participants have been reported in temporal learning, the role of dimensions of individual variability in affecting performance in such tasks is still unclear. Here we investigated this issue, assessing the effect of field-dependent/independent cognitive style on temporal learning in the suprasecond range. Since different mechanisms mediate timing when a temporal representation is self-generated, and when it depends on an external referent, temporal learning was assessed in two conditions. Participants observed a stimulus across six repetitions and reproduced it. Unbeknownst to them, in an internally-based learning (IBL) condition, the stimulus duration was fixed within a trial, although the number of events defining it varied; in an externally-cued learning (ECL) condition, the stimulus was defined by the same number of events within each trial, although its duration varied. The effect of the reproduction modality was also assessed (motor vs. perceptual). Error scores were higher in IBL compared to ECL; the reverse was true for variability. Field-independent individuals performed better than field-dependent ones only in IBL, as further confirmed by correlation analyses. Findings provide evidence that differences in dimensions of variability in high-level cognitive functioning, such as field dependence/independence, significantly affect temporal learning in the suprasecond range, and that this effect depends on the type of temporal representation fostered by the specific task demands.
事件或动作时间信息的获取(时间学习)发生在亚秒和超秒范围内。然而,尽管在时间学习中已经报道了参与者之间的相关差异,但个体变异性维度对这些任务中表现的影响仍不清楚。在这里,我们研究了这个问题,评估了场依存/独立认知风格对超秒范围内时间学习的影响。由于当时间表示是自我生成的,并且当它依赖于外部参照时,不同的机制介导计时,因此在两种条件下评估了时间学习。参与者观察了六个重复的刺激并进行了复制。在内部学习(IBL)条件下,他们并不知道,尽管定义它的事件数量不同,但刺激持续时间在一次试验中是固定的;在外部提示学习(ECL)条件下,尽管每个试验中刺激的持续时间不同,但刺激由相同数量的事件定义。还评估了再现模式的效果(运动与知觉)。与 ECL 相比,IBL 的错误得分更高;而在可变性方面则相反。仅在 IBL 中,场独立个体的表现优于场依存个体,相关性分析进一步证实了这一点。研究结果表明,高水平认知功能变异性维度的差异,如场依存/独立性,会显著影响超秒范围内的时间学习,并且这种影响取决于特定任务需求所促进的时间表示类型。
