چکیده
هدف تحقیق حاضر مقایسه تاثیر فاصله متفاوت آزمون خاطرآوری بر یادگیری و پردازش تحکیم مبتنی بر ارتقاء در حافظه حرکتی آشکار آشکار بود. آزمودنی های تحقیق را 36 دانشجو تشکیل می دادند که به طور تصادفی در سه گروه آزمایشی با فاصله آزمون خاطرآوری فوری، تاخیری 6 ساعت و تاخیری 24 ساعت تقسیم شدند. تکلیف زمان عکس العمل زنجیره ای در تحقیق حاضر مورد استفاده قرار گرفت. در مرحله اکتساب گروه ها به اجرای تکلیف در 15 بلوک 80 کوششی (سه ایپوک 400 کوششی) پرداختند. سپس در آزمون خاطرآوری، گروه ها پنج بلوک 80 کوششی (یک ایپوک 400 کوششی) از تکلیف را اجرا کردند. داده ها با روش آماری تحلیل واریانس با اندازه های تکراری تحلیل شد. در مرحله اکتساب اثر اصلی گروه و اثر تعاملی گروه در ایپوک تمرینی معنی دار نبود اما اثر اصلی ایپوک تمرینی معنی دار بود و تمرین باعث افزایش میانگین تفاوت زمان عکس العمل توالی در ایپوک سوم نسبت به ایپوک های اول و دوم شده بود. در مرحله خاطرآوری اثر اصلی ایپوک تمرینی و اثر تعاملی گروه در ایپوک تمرینی معنی دار بود. نتایج آزمون تعقیبی دانکن نشان داد صرفا گروه با فاصله آزمون خاطرآوری 24 ساعت، در ایپوک آزمون خاطرآوری عملکرد بهتری نسبت به ایپوک سوم در مرحله اکتساب داشت. لذا، فاصله زمانی 24 ساعت برای اجرای آزمون خاطرآوری بهینه ترین فاصله برای ارتقاء حافظه حرکتی آشکار است.

چکیده English

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.
