چکیده
در این پژوهش ابعاد انگیختگی فیزیولوژیک و اضطراب شناختی شرایط عادی و فشار و تأثیر آن‌ها بر دقت عملکرد و ویژگی‌های کینماتیک حرکت سلاح در دو گروه نخبه و نوآموز بررسی شد. انگیختگی فیزیولوژیک با سطح هدایت الکتریکی پوست ثبت شد. دقت عملکرد و ویژگی‌های کینماتیک سلاح (زمان حرکت، اوج سرعت سلاح، جابه‌جایی در محور افقی و عمودی) در دو گروه توسط تحلیل واریانس مرکب با اندازه‌های تکراری آزمون شد. افزایش انگیختگی فیزیولوژیک و اضطراب حالتی از شرایط عادی به فشار نشان‌دهنده ایجاد شرایط فشار بود. افزایش بیشتر انگیختگی فیزیولوژیک در گروه نوآموز منجر به افزایش اوج سرعت سلاح و جابه‌جایی در محورعمودی و کاهش دقت عملکرد شد. در مقابل، در شرایط فشار دقت عملکرد گروه نخبه با کاهش جابه‌جایی در محور افقی و عمودی افزایش یافت. یافته‌ها از پیش‌بینی مدل فاجعه که بر اساس ارتباط عملکرد حرکتی با انگیختگی فیزیولوژیک و اضطراب شناختی مفهوم‌سازی شده، حمایت کرد.

چکیده [English]
The present study investigated the effects of physiological arousal and cognitive anxiety on performance accuracy and kinematic features of gun in expert and novice groups. The physiological arousal was recorded with skin conductance response. Performance accuracy and kinematic features of gun such as total movement time, peak velocity, displacement in horizontal and vertical axis were measured by using mixed variance analysis test with repeated measures design. Increased physiological arousal and anxiety showed induced pressure conditions. More increase in the physiological arousal in novice group led to an increase in the peak velocity and the displacement in the vertical axis of the gun and a reduction of the performance accuracy. However, the performance of the expert group increased with decreased displacement in two axes under pressure conditions. The findings support the prediction of the catastrophe model, which conceptualized based on the relationship of motor performance with physiological arousal and cognitive anxiety.
