Research on serial order memory has traditionally used tasks where participants passively view the items. A few studies that included hand movement showed that such movement interfered with serial order memory. In the present study of three experiments, we investigated whether and how hand movements improved spatial serial order memory. Experiment 1 showed that manual tracing (i.e., hand movements that traced the presentation of stimuli on the modified eCorsi block tapping task) improved the performance of backward recall as compared to no manual tracing (the control condition). Experiment 2 showed that the facilitation effect resulted from voluntary hand movements and could not be achieved via passive viewing of another person's manual tracing. Experiment 3 showed that it was the temporal, not the spatial, signal within manual tracing that facilitated spatial serial memory.

手部运动在空间序列顺序记忆中的作用

对序列订单记忆的研究传统上使用参与者被动查看项目的任务。一些包括手部运动的研究表明，这种运动会干扰序列顺序记忆。在目前对三个实验的研究中，我们调查了手部运动是否以及如何改善空间序列顺序记忆。实验 1 表明，与没有手动跟踪（控制条件）相比，手动跟踪（即跟踪修改后的 eCorsi 块敲击任务中的刺激呈现的手部运动）提高了向后回忆的性能。实验 2 表明，促进效果是由随意的手部运动产生的，不能通过被动查看另一个人的手动跟踪来实现。实验 3 表明它是时间的，而不是空间的，
