چکیده
مدت زمان سپریشده پس از یادگیری یک تکلیف توالی حرکتی حافظه پنهان، از تحکیم آن حمایت میکند؛ اما هنوز مشخص نیست که آیا این گذر زمان و فعالیت انجامشده در این دورة زمانی موجب تثبیت یا افزایش در عملکرد توالی حرکتی میشود یا خیر؛ بنابراین، هدف مطالعة حاضر، ارزیابی دورة زمانی با مداخلات خاص بر تحکیم حافظة پنهان در انسان بود. بدینمنظور، 45 نفر از افراد داوطلب تکلیف تطبیق رنگ زنجیرهای را در سه بلوک 150 کوششی اجرا کردند و سپس، بهصورت تصادفی در سه گروه قرار گرفتند. گروه اول پس از گذشت یک ساعت و گروه دوم پس از گذشت شش ساعت در تکلیف متقابلة شست شرکت کردند. گروه سوم هیچ تکلیف مداخلهای دریافت نکردند. سپس، هر سه گروه پس از گذر 24 ساعت از تکلیف هدف، در آزمون یادداری شرکت کردند. نتایج آزمون یادداری گروههای موردبررسی اختلاف معناداری را بین اکتساب و یادداری تکلیف تطبیق رنگ زنجیرهای نشان نداد. یافتة پژوهش حاضر میتواند بیانگر این نکته باشد که حافظة حرکتی پنهان بلافاصله پس از یادگیری تثبیت میشود و انجام تکلیف تداخلی متقابلة شست و گذر زمان اثری افزایشی یا کاهشی بر حافظة حرکتی پنهان ندارد. درواقع، تحکیم این حافظه مبتنیبر ثبات است.

چکیده [English]
Time supports the consolidation of motor sequence memories, yet it remains unclear whether time duration and doing specific task in this time, stabilizes or actually enhances motor sequence performance. The aim of this study was to investigate time duration with specific interference on consolidation human motor memory. Forty-five healthy volunteer participate performed Serial Color matching task for three blocks of 150 trials. They randomly divided into three group, 1) after one hour 2) after six hour performed finger-to-thumb opposition task 3) without any interference. All group after 24 hour participated in retention test. The result show no significant differences between acquisition and retention stages. These findings indicate rapid stabilization of implicit motor memory and interference sequential finger-to-thumb opposition task and time had no enhancement or reducer effect on implicit motor memory, but rather stabilizes motor sequence performance without producing additional gains.
