مقايسه تاثير دو روش تغييرپذيري بر يادگيري مهارت ضربه گلف: تداخل زمينه اي و يادگيري افتراقي

The Comparison of two methods of variability on the learning of golf putting: Contextual Interference and Differential leaning

هدف از پژوهش حاضر مقايسه تأثير دو روش تغييرپذيري (تداخل زمينه‌اي و يادگيري افتراقي) بر يادگيري مهارت ضربه گلف بود. بدين منظور 50 دختر دانشجو (ميانگين سني=7/1± 6/21) به‌صورت تصادفي در پنج گروه تداخل زمينه‌اي مسدود، تداخل زمينه اي تصادفي ، يادگيري افتراقي مسدود ، يادگيري افتراقي تصادفي و كنترل تقسيم شدند. شركت‌كنندگان پس از پيش‌آزمون، بر اساس گروه‌بندي مربوطه، تكليف گلف را به مدت سه روز متوالي (هرروز 10 بلوك 12 كوششي) تمرين نمودند. سپس آزمون يادداري فوري را 10 دقيقه پس از آخرين جلسه اكتساب و آزمون يادداري تأخيري را 72 ساعت بعد از آخرين جلسه اكتساب انجام دادند. آزمون انتقال نيز با همين ترتيب انجام شد. نتايج نشان داد كه گروه‌هاي يادگيري افتراقي در مراحل آزمون‌هاي يادداري تفاوت معني‌داري با گروه تداخل زمينه اي تصادفي ندارند (05/0

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.
