大量证据表明，巩固的记忆在重新激活后容易受到修改。记忆巩固和再激活诱导的技能调节过程通常在数小时或数天后被记录。受研究显示运动技能获得早期阶段快速巩固的启发，我们在这里询问运动技能记忆是否容易在短暂的重新激活后进行修改，即使在学习的初始阶段。在一组实验中，我们收集了众包的在线运动序列数据，以测试在学习的早期阶段短暂重新激活后是否会发生编码后干扰和性能增强。结果表明，在早期学习过程中形成的记忆是不容易受到干扰，也不增强快速再激活诱导的时间窗口内，相对于控制条件。这组证据表明，再激活诱导的运动技能记忆调节可能依赖于宏观时间尺度水平的巩固，需要数小时或数天的时间发生。
Abundant evidence shows that consolidated memories are susceptible to modifications following their reactivation. Processes of memory consolidation and reactivation-induced skill modulation have been commonly documented after hours or days. Motivated by studies showing rapid consolidation in early stages of motor skill acquisition, here we asked whether motor skill memories are susceptible to modifications following brief reactivations, even at initial stages of learning. In a set of experiments, we collected crowdsourced online motor sequence data to test whether post-encoding interference and performance enhancement occur following brief reactivations in early stages of learning. Results indicate that memories forming during early learning are not susceptible to interference nor to enhancement within a rapid reactivation-induced time window, relative to control conditions. This set of evidence suggests that reactivation-induced motor skill memory modulation might be dependent on consolidation at the macro-timescale level, requiring hours or days to occur.
