| هدف از پژوهش حاضر بررسی یادگیری تکالیف پیچیده دودستی نامتقارن در ترکیبی از ویژگیهای سرعت، اثر جاذبه و دامنه حرکت بود. ابزار مورد استفاده در پژوهش حاضر شامل قلم نوری با حسگر ویژه، لپ تاپ، دستکش ویژه و مترونوم بود. جامعه آماری تحقیق حاضر را دانش-آموزان پسر پایه هشتم (با میانگین سنی 0/13± 14/2) در مدرسه شهید ابراهیمی اهواز تشکیل دادند،که همگی راست دست بودند و هیچگونه آشنایی قبلی در مهارت مورد نظر نداشتند. آزمودنیها بطور داوطلبانه در پژوهش شرکت نمودند و به طور تصادفی در سه گروه، گروه اول (n=10)، گروه دوم (n=10) و گروه سوم (n=10) قرار گرفتند. سه گروه آزمودنی باید تکلیف نامتقارن دودستی را به دو صورت تکلیف دشوار با دست برتر (تکلیف تمرینی) و تکلیف دشوار با دست غیربرتر (تکلیف انتقال)، در پیش آزمون و پس آزمون انجام میدادند. گروهها پس از پیش‌آزمون به مدت سه روز تمرین نموده سپس پس آزمون‌ها به عمل آمد. نامتقارنی در گروه اول به معنای تفاوت در سرعت و جهت حرکت دو دست، در گروه دوم تفاوت سرعت و اثر جاذبه بر دو دست و در گروه سوم تفاوت در اندازه حرکت و اثر جاذبه بر دودست بود. نتایج نشان داد که تمرین در گروه اول، باعث اکتساب و انتقال مثبت حرکت دودستی نامتقارن به حالت عکس آن میشود. در گروه دوم انتقال صفر و در گروه سوم انتقال منفی بود. به نظر میرسد در تفاسیری که بر اساس نظریه‌های سلسله مراتبی صورت میگیرد باید بیش از دو سطح برای کنترل حرکات دودستی در نظر گرفت. به عبارتی سطوح متفاوتی از دشواری تکلیف را در نظر گرفت. | ||

| چکیده [English] | ||
| The aim of this study was the evaluation of learning and transfer of asymmetric bimanual complex tasks in combination of features of speed, gravity and amplitude. The instruments used in this study included pen Mouse, laptop, special glove and metronome. The subjects of the research were eight grade, right-handed students (mean age, 14.2±0.13) of Shahid Ebrahimi school of Ahvaz, who had no familiarity with desired skill. The subjects voluntarily participated in the study and randomly and evenly into three groups, the first group(n=10), second group(n=10) and the third group(n=10). Three test groups have performed the asymmetric bimanual task in two ways difficult task with the dominant hand (training task) as well as a difficult task with non-dominant hand (transfer task), in pre-test and post-test. The movement patterns of two hands were different from each other in movement features (first group: direction and velocity pattern, second group: velocity pattern and effect of gravity, third group: amplitude and effect of gravity). Each of the test groups after the practice run for three days and then tests were performed. The results showed that in first group, transfer to vice versa pattern is positive. However, in second group, there is a positive transition and the transition is zero, and in third group, transfer to vice versa pattern is negative. Seems interpretations that are made on the basis of the hierarchical theory should be considered more than two levels of control bimanual movements, In other words, different levels of difficulty of the task. | ||
