The Effect of Time Course of Retention and Interference on Implicit Motor Memory Stabilization

The aim of this study was to compare the effect of time courses of interference and retention test on implicit motor memory consolidation. 60 right-handed female students who had cognitive, mental and physical health and novice at performing alternating serial reaction time task (ASRTT) and serial color matching task (SCMT) (mean age=21.95.95 years) were randomly divided into three groups of interference with distances of 6, 24 and 72 hours after the practice session. In the acquisition phase, all groups practiced the ASRTT in 25 blocks of 80 trials in one day. Then, they participated in the second interference task (SCMT) 6, 24 and 72 hours after the practice session and participated in the retention test 24 hours later. In the acquisition phase, subjects’ performance improved with an increase in the practice trials and they had better performance in the 5th practice block (P
