高工作记忆容量（WMC）与视觉运动适应增强之间关系的理论基础尚不清楚。视觉运动适应涉及外显系统和内隐系统之间的相互作用。我们研究了适应与WMC之间的正相关是否仅限于适应的外显成分。实验1重复了WMC与适应之间的正相关关系，但发现这是特定于适应的外显成分的，并且显然是由未表现出正确方向的外显适应的亚组参与者驱动的。WMC与内隐学习呈负相关。实验2和3表明，当任务限制外显策略的发展时，高WMC不再与适应增强相关。这项研究表明，高WMC的好处与个体使用显式策略的能力密切相关。它还揭示了个体差异在决定如何进行适应方面的重要贡献。
The theoretical basis for the association between high working memory capacity (WMC) and enhanced visuomotor adaptation is unknown. Visuomotor adaptation involves interplay between explicit and implicit systems. We examined whether the positive association between adaptation and WMC is specific to the explicit component of adaptation. Experiment 1 replicated the positive correlation between WMC and adaptation, but revealed this was specific to the explicit component of adaptation, and apparently driven by a sub-group of participants who did not show any explicit adaptation in the correct direction. A negative correlation was observed between WMC and implicit learning. Experiments 2 and 3 showed that when the task restricted the development of an explicit strategy, high WMC was no longer associated with enhanced adaptation. This work reveals that the benefit of high WMC is specifically linked to an individual’s capacity to use an explicit strategy. It also reveals an important contribution of individual differences in determining how adaptation is performed.
