تاثيرخطاي ادراك بينايي و تعداد كوشش‌هاي تمرين بر تسهيل يادگيري مهارت حركتي

The effect of visual illusion and the number of practice efforts on facilitating motor skills learning

هدف: هدف از پژوهش حاضر بررسي تاثير خطاي ادراك بينايي و تعداد كوشش هاي تمرين بر تسهيل يادگيري مهارت حركتي بود. روش‌ها: تعداد 32 دانش آموز با ميانگين سني 9/0± 43/10 انتخاب و بر اساس نوع خطاي بينايي (ادراك بزرگ‌تر هدف و ادراك كوچك‌تر هدف) به دو گروه 16 نفره تقسيم شدند. شركت كنندگان هر گروه پس از انجام 30 كوشش تمريني جهت آشنايي با اجراي مهارت شوت تيله از فاصله 65 سانتيمتري مركز هدف، تعداد 540 كوشش مربوط به گروه خود را طي 6 جلسه انجام دادند سه آزمون انتقال بدونه دايره هاي اطراف به شكلي كه پس از هر 180 كوشش يك آزمون يادداري به عمل آمد. جهت تحليل داده ها از آزمون تحليل واريانس مركب با اندازه هاي تكراري و آنواي يك راهه استفاده گرديد. نتايج: نتايج تفاوت معناداري را بين گروه تمرين با خطاي بينايي بزرگ و كوچك نشان داد كه وابسته به ميزان پيشرفت افراد است (05/0

Purpose: The aim of this study was to investigate the effect of visual illusion and the number of practice attempts on facilitating motor skill learning. Methods: A number of 32 students with a mean age of 10.43 ± 0.9 were selected and divided into two groups of 16 based on the type of visual illusion (target appears larger and the target appears smaller). The participants of each group, after performing 30 training attempts to get acquainted with the execution of marble shooting skills from a distance of 65 cm from the target center, performed 540 attempts related to their group in 6 sessions; Three retention tests were performed in such a way that one test was performed after every 180 attempts. To analyze the data, a Mixed ANOVA with repeated measures and one-way ANOVA was used. Results: The results showed a significant difference between the exercise group with large and small visual illusions, which depends on the level of rate of progress of individuals (P <0.05). Conclusion: The results of the present study, by confirming the challenge point hypothesis, suggest that in order to improve the accuracy of targeting, first people
