This study investigated toddlers' ability to control simple alternating pattern actions, and how this relates to motor competence and executive functions. 70 toddlers between 24 and 36 months of age were instructed to sort coins in an alternating pattern into two boxes; left, right, left, right etc. Executive functions and memory competence performance were assessed in additional small games. The results showed that the ability to plan and execute actions according to a simple extended alternating pattern improved over toddlerhood. Furthermore, working memory and motor competence scores were both independent predictors of the ability to plan and execute simple alternating actions. These findings underscore the fact that between 24 and 36 months of age is a period in which the ability to string together multiple actions in a sequence to achieve a distal goal is still developing.
本研究调查了幼儿控制简单交替模式动作的能力，以及这与运动能力和执行功能之间的关系。研究人员指示70名年龄在24至36个月之间的幼儿以交替模式将硬币分别放入两个盒子中，即左、右、左、右等等。通过额外的小游戏评估执行功能和记忆能力表现。结果表明，根据简单的扩展交替模式计划和执行动作的能力在幼儿期有所提高。此外，工作记忆和运动能力得分都是计划和执行简单交替动作能力的独立预测因素。这些发现强调了这样一个事实，即24至36个月的年龄段是一个人将多个动作按顺序串联起来以实现远期目标的能力仍在发展的时期。
