چکیده

هدف از انجام این پژوهش، بررسی تأثیر دست‌کاری کانون توجه بر اجرای ضربة فورهند تاپ اسپین بازیکنان ماهر و مبتدی تنیس روی میز در شرایط فشار روانی بالا بود. تعداد 30 نفر (15 ماهر و 15 مبتدی) در این پژوهش شرکت کردند. افراد در شرایط فشار روانی بالا و پایین و کانون‌های توجهی مختلف (حالت یک‌تکلیفی، تکیف دوگانه با توجه درونی، تکلیف دوگانه با توجه بیرونی نامرتبط و تکلیف دوگانه با توجه بیرونی مرتبط) ضربة تاپ اسپین را اجرا کردند. نتایج نشان داد که گروه­ مبتدی در حالتی که توجه آن‌ها به‌‌سمت درون هدایت شده بود، افت کمتری در شرایط فشار روانی بالا داشتند. در گروه ماهر، زمانی‌که توجه آن‌ها به‌سمت بیرون بود (مرتبط یا نامرتبط)، در شرایط فشار بالا افتی در عملکرد آن‌ها دیده نشد. این نتایج با توجه به اثر دوگانة فشار روانی و همچنین، بحث کنترل درجات آزادی توجیه شد.

چکیده [English]

The purpose of this study was to examine the effect of manipulating attentional focus on performance of top-spine strike of skilled and novice table tennis players under high psychological pressure. Thirty (15 skilled and 15 novices) persons participated in this study. Participants performed top-spine strike under high/low psychological pressure and different attentional focus conditions (single task, dual task with internal focus, dual task with irrelevant external attention, dual task with relevant external attention). Results revealed that novice group experienced lower decrease during high psychological pressure when their attentional focus was directed internally. No decrease was observed in the performance of skilled group when their attention was directed externally (relevant or irrelevant) during high pressure. These results were explained according to the dual effect of psychological pressure and the notion of controlling degrees of freedom.
