The aim of this research was effect of immediate, recent and remote explicit motor memory on reconsolidation process based stabilization and enhancement and retrograde interference. The statistical sample were 72 right-handed young girl. subjects were divided into two groups of  immediate explicit motor  memory (immediate recall, immediate recall + immediate interference), two groups of  recent explicit motor memory(recall after 5h, recall after 5h + Interference delayed after 5h) and two groups of  remote explicit motor  memory (recall after 24h, recall after 24h + Interference delayed after 24h). This research was consisted of two phases of acquisition and retention and alternating serial reaction time and two selection reaction time tasks were used. In the first phase check out reconsolidation based enhancement and in the second phase check out reconsolidation based stabilization and retrograde interference. In the first phase, results showed that for recall groups after 24h and 5h occurred reconsolidation based enhancement. In the second phase, results showed that for  recent (recall after 5h, recall after 5h + Interference delayed after 5h) and remote (recall after 24h, recall after 24h + Interference delayed after 24h) memory groups occurred reconsolidation based stabilization. In group with immediate offline period (immediate recall+ immediate interference) occurred retrograde interference effect.

The purpose of this study was to examine the effect of different recall distance‌s on explicit motor memory consolidation. Thirty Six students were randomly divided into three groups with distance of immediate, 6, and 24 hours in recall test. This research consisted of two phases of acquisition and recall. In acquisition period, all groups practiced the task for 15 blocks of 80 trials (five epochs of 400 trails). Then in recall phase, all experimental groups were practiced five blocks of  80 trials (one epoch of 400 trails). Also, all groups practiced the alternating serial reaction time task in each epoch. Data were analyzed with using the ANOVA repeated measure. Results showed that in acquisition phase the group main effect and interaction effect between group and epoch were not significant. But epoch main effect was significant and practice lead to inducing sequence reaction time in third epoch related to other epochs. In recall phase, the epoch main effect and interactive effect between group and epoch were significant, but group main effect was not significant. Results in Duncan Post Hoc showed that only group with 24h off line periods, in recall test, had the better performance than acquisition phase.  Practice in group with 24h offline lead to decrease the reaction time than other group .Our Results indicated that 24h offline period for recall test is better time for optimal performance.

The aim of this study was to examine the effect of aerobic and strength exercises and interactive time circadian rhythms of everyday memory performance, retrospective and prospective youth. Methods quasi-experimental, pretest - posttest randomized groups. 48 participants were randomly divided into four groups: aerobic training STR X in the morning (n =12), strength training fitness in the morning (n =12), exercise STR X age (n =12), and strength training fitness in age (n =12), the exercise period of 2 months (8 weeks, 3 times a week, and every 45 minutes) respectively. Participants Pittsburgh Sleep Quality Index (PSQI), a questionnaire circadian cycles Steve Horn questionnaire prospective and retrospective memory and RAM questionnaires were completed daily.Inferential statistics such as ANOVA test of the indicators in the pre-test and post-test in two-way ANOVA and Bonferroni post hoc test was used to analyze the data. Results showed that participants in training t-RX power in the morning and in the evening a higher average daily memory. And participants in training t-RX and power in both the morning and evening with retrospective memory were weaker. Average memory function prospective and retrospective exercises T oryx and fitness in the morning and evening statistically significant difference, and people in the morning activities with prospective memory and retrospective better than those in the era of work , have. The average daily memory exercises and fitness in the morning and evening t oryx statistically significant, and people who are active in the afternoon with daily memory better. Physical activity and aerobic training and strength is increasing everyday memory. (P < 0.05)In the meantime, do cardio in the morning and in the evening can improve the power performance is better.
