Skill reconsolidation does not operate at a rapid micro-timescale level

Abundant evidence shows that consolidated memories are susceptible to modifications following their reactivation through reconsolidation. Processes of memory consolidation and reconsolidation have been commonly documented after hours or days. Motivated by studies showing rapid consolidation in early stages of skill acquisition, here we asked whether skill memories are susceptible to modifications through rapid reconsolidation, even at initial stages of learning. In a set of experiments, we collected crowdsourced online motor sequence data to test whether post-reactivation interference and enhancement occur through rapid reconsolidation. Results indicate that memories forming during early learning are not susceptible to interference nor to enhancement within a rapid reconsolidation time window, relative to control conditions. This set of evidence suggests that memory reconsolidation might be dependent on consolidation at the macro-timescale level, requiring hours or days to occur.
