چکیده

هدف از پژوهش حاضر مقایسه تأثیر دو روش تغییرپذیری (تداخل زمینه‌ای و یادگیری افتراقی) بر یادگیری مهارت ضربه گلف بود. بدین منظور 50 دختر دانشجو (میانگین سنی=7/1± 6/21) به‌صورت تصادفی در پنج گروه تداخل زمینه‌ای مسدود، تداخل زمینه ای تصادفی ، یادگیری افتراقی مسدود ، یادگیری افتراقی تصادفی و کنترل تقسیم شدند. شرکت‌کنندگان پس از پیش‌آزمون، بر اساس گروه‌بندی مربوطه، تکلیف گلف را به مدت سه روز متوالی (هرروز 10 بلوک 12 کوششی) تمرین نمودند. سپس آزمون یادداری فوری را 10 دقیقه پس از آخرین جلسه اکتساب و آزمون یادداری تأخیری را 72 ساعت بعد از آخرین جلسه اکتساب انجام دادند. آزمون انتقال نیز با همین ترتیب انجام شد. نتایج نشان داد که گروه‌های یادگیری افتراقی در مراحل آزمون‌های یادداری تفاوت معنی‌داری با گروه تداخل زمینه ای تصادفی ندارند (05/0<P)، اما در مرحله انتقال گروه‌های یادگیری افتراقی دقت بالاتری را از خود نشان دادند(05/0 P <)؛ بنابراین، تغییرات مداوم ایجادشده در یادگیری افتراقی، احتمالا به دلایلی مانند ظهور جاذب های وابسته به خود و وابسته به زمینه و همچنین پدیده نوسانات تصادفی، قابلیت تعمیم‌پذیری بیشتری نسبت الگویی را داشته که توسط تمرین تداخل زمینه ای ایجادشده است.

چکیده [English]

This study was aimed to compare the effect of two methods of variability (contextual interference and differential learning) on the learning in golf putting. For this purpose, 50 female students (mean age 21.6 ± 1.7) were randomly divided into five groups, including blocked contextual interference (BCI), random contextual interference (RCI), blocked differential learning (BDR), random differential learning (RDR), and control. After a pre-test, participants practiced the putting task for three consecutive days (10 blocks per day, 12 trails each) according to their grouping. Ten minutes and 72 hours after the last practice session, the immediate and delayed retention tests were performed, respectively. Also, the participants completed a transfer test. Results for the retention tests did not show a significant difference between differential learning groups and the random contextual interference group (p > 0.05), while during the transfer phase, differential learning groups showed higher accuracy (p < 0.05). Therefore, the continuous changes in differential learning Probably for reasons like the emergence of the subject and context-dependent attractors also the phenomenon of Stochastic perturbations seems to be more generalizable than the pattern created by contextual interference.
