چکیده

قید شناختی از جمله قیود فردی است که می‌توان آن را با تصویرسازی ایجاد کرد و در بسیاری از تکالیف به‌عنوان عاملی اثرگذار بر عملکرد بررسی می‌شود. ازاین‌رو هدف از تحقیق حاضر، بررسی تأثیر قید شناختی بر مهارت پاس دقت و سرعت بود. بدین‌منظور 44 نفر از دانشجویان دختر دانشکدۀ تربیت بدنی دانشگاه تهران (با میانگین سنی 3/2±45/22 سال) به‌صورت در دسترس انتخاب شدند و در این تحقیق شرکت کردند. آزمودنی‌ها پس از اجرای پیش‌آزمون به‌صورت دو بلوک 10 کوششی از پاس دقت و سرعت بسکتبال، به‌صورت همگن در یکی از چهار گروه تصویرسازی پاس دقت، پاس سرعت، گروه کنترل دقت و سرعت قرار گرفتند. دو گروه تصویرسازی فایل صوتی تصویرسازی را سه روز به مدت 8 دقیقه گوش دادند؛ پس از آن پس‌آزمون و آزمون‌های یادداری، انتقال از آزمودنی‌ها گرفته شد. به‌منظور تجزیه‌وتحلیل داده‌ها از آزمون تحلیل واریانس مرکب و در صورت مشاهدۀ معناداری از آزمون تی مستقل برای مقایسۀ بین‌گروهی، همچنین آزمون تحلیل واریانس با اندازه‌های تکراری برای مقایسۀ درون‌گروهی و سنجش میزان پیشرفت آزمودنی‌ها در سطح معناداری (05/0=α) استفاده شد. نتایج تحلیل واریانس تفاوت معناداری را در پیش‌آزمون گروه‌های تصویرسازی و کنترل نشان نداد. اما بین گروه‌های تصویرسازی و گروه کنترل در پس‌آزمون، یادداری و انتقال تفاوت معناداری مشاهده شد (05/0≥p ). همچنین تصویرسازی پتلپ پاس دقت و سرعت، به بهبود اجرای پاس دقت و سرعت آزمودنی‌ها از پیش‌آزمون تا یادداری منجر شد؛ اما این روند در آزمون انتقال دیده نشد (05/0≤p ).

چکیده [English]

Cognitive constrain of individual constrains which can be created with imagery and is a factor in many tasks affecting the performance has been investigated. Thus, the aim of the present study was to investigate the effect of PETTLEP imagery on the accuracy and speed basketball pass skill. 44 female students of Faculty of Physical Education, University of Tehran (mean age of 22.45±2.3 years) were selected by convenience sampling method and participated in this study. In pretest, participants performed 2 blocks of 10 trials of accuracy and speed basketball pass. Then, they were assigned to one of the four groups homogeneously: accuracy pass PETTLEP imagery, speed pass PETTLEP imagery, accuracy control, and speed control. Two groups of imagery listened to the imagery audio during 3 days for 8 minutes per day. Then, subjects participated in posttest, retention and transfer tests. For data analysis, mixed ANOVA was used. In case of significance, independent t test was used for intergroup comparisons and analysis of variance with repeated measures was used for within-group comparisons with significance level of α=0.05. The results of analysis of variance indicated no significant differences between imagery and control groups in pretest. However, there were significant differences in posttest, retention and transfer tests between imagery and control groups (P≤0.05). Also, PETTLEP imagery of accuracy and speed pass improved accuracy and speed pass performance from pretest to retention test; however, there was no such process in transfer test (P≥0.05).
