Abstract

The purpose of this study was to examine the effect of sleep and wake on implicit motor sequence consolidation. The statistical population of present research was female students in human science feilds of Shahid Beheshti University. The statistical sample of this study was 40 right-handed volunteer female students and randomly divided into two groups with distance of 10 minute and 48 hours in recall test. This research consisted of two phases of acquisition and retention. Alternating serial reaction time task with provide repeated and randomized sequences as an alternating method was used for this research. In acquisition period, all groups practiced the alternating serial reaction time task in each epoch. Data were analyzed with using the ANOVA repeated measure and Bonferroni Post Hoc tests. Results showed that in acquisition phase the group main effect and interaction effect between group and epoch were not significant (P>0.05). But epoch main effect was significant and practice lead to increasing difference of random and reaped sequence reaction time in fifth epoch related to other epochs. In recall phase, the epoch main effect and interactive effect between group and epoch were significant (P<0.05), but group main effect was not significant (P>0.05). All groups, in recall test, showed the better performance than acquisition phase. Practice in group with 48h offline lead to decrease the reaction time than other groups. On the other hand, the group with 48h recall lead to a significant decrease in reaction time mean (P<0.05). Our Results indicated that make offline period after sleep of night phase could be facilitated the implicit motor sequence consolidation.
