Associations between cognitive and motor timing performance are documented in hundreds of studies. A core finding is a correlation of about - 0.3 to - 0.5 between psychometric intelligence and time interval production variability and reaction time, but the nature of the relationship remains unclear. Here, we investigated whether this relation is subject to near and far transfer across a battery of cognitive and timing tasks. These tasks were administered pre- and post-five daily 30 min sessions of sensorimotor synchronization training with feedback for every interval. The training group exhibited increased sustained attention performance in Conners' Continuous Performance Test II, but no change in the block design and figure weights subtests from the WAIS-IV. A passive control group exhibited no change in performance on any of the timing or cognitive tests. These findings provide evidence for a direct involvement of sustained attention in motor timing as well as near transfer from synchronization to unpaced serial interval production. Implications for the timing-cognition relationship are discussed in light of various putative timing mechanisms.

运动定时训练可改善持续的注意力表现，但不能改善体液智力：近距离但远距离转移。

数百项研究记录了认知与运动时机表现之间的关联。一个核心发现是心理测验智力与时间间隔产生变异性和反应时间之间的相关性约为-0.3至-0.5，但这种关系的性质仍不清楚。在这里，我们调查了这种关系是否受一系列认知和定时任务的远近转移的影响。在五次之前和之后的每天30分钟的感觉运动同步训练中对这些任务进行管理，并在每个间隔内进行反馈。培训小组在Conners的“持续表现测试II”中表现出了持续注意力增强的表现，但在WAIS-IV的方块设计和图形权重子测试中没有任何变化。被动对照组在任何时机或认知测试中均未表现出任何变化。这些发现提供了持续关注运动正时的直接参与以及从同步到无节奏连续间隔产生的几乎转移的证据。根据各种假定的计时机制讨论了对计时-认知关系的影响。
