چکیده

مقدمه: اختلالات خواب در جوامع نظامی شایع است و به‌نوبه‌خود بر کارکردهای شناختی فرد اثرگذار است. هدف از این مطالعه، بررسی تأثیر یک دوره محرومیت از خواب بر میزان توجه انتخابی، تمرکز، تلاشمندی و نمره تیراندازی افراد نظامی بود.
روش: 10 نفر از سربازان یک مرکز نظامی به‌صورت تصادفی انتخاب شدند و ضمن محرومیت 30 ساعته از خواب، عملکرد توجه، تمرکز و تلاشمندی ایشان (با استفاده از آزمون d2) و همچنین نمره تیراندازی آنها به وسیله تفنگ بادی، ارزیابی و با عملکرد قبل از آن مقایسه شد.
نتایج: داده‌ها با استفاده از آزمون تحلیل واریانس در سطح معنی‌داری 05/0 مورد بررسی قرار گرفت. نتایج نشان داد که 30 ساعت محرومیت از خواب، موجب کاهش معنی­دار امتیاز تیراندازی (003/0=p) شد. ازطرفی میزان مؤلفه­های مرتبط با توجه، تمرکز و تلاشمندی، یا کارایی کل آزمودنی­ها )11/0p=)، یا میزان نمره خطا (31/0=p) و تمرکز (23/0=p) تغییر معنی‌داری نداشتند.
بحث: به‌طورکلی می­توان گفت که هر چند محرومیت از خواب درنظر گرفته شده، موجب اختلال در توجه، تمرکز و تلاشمندی افراد نظامی نشد؛ ولیکن نمره تیراندازی آنها را به‌طور معنی­دار کاهش داد و این کاهش امتیاز حاکی از مستقل‌بودن عوامل ذهنی در رابطه با محرومیت از خواب آزمودنی­های این تحقیق بوده است.

چکیده [English]

Introduction: Sleep disorder is common in military circles and, in turn, affects the cognitive functions of an individual. This study is aimed at examining the effect of a period of sleep deprivation on the selective attention, concentration, effortfulness and shooting scores of military personnel.
Method: Ten soldiers of a military center were randomly selected and while being deprived of 30 hours of sleep, their attention, concentration and effortfulness performance (by d2 test) as well as their rifle shooting scores were evaluated and compared with their previous records.
Results: The collected data were analyzed using analysis of variance at the significance level of 0.05. The results revealed that 30 hours of sleep deprivation caused a significant decrease in shooting scores (p = 0.003). On the other hand, the rate of the components related to attention, concentration and effortfulness, or the total efficiency of the subjects   (p = 0.11), or the error score (p = 0.31) and concentration (p = 0.23) did not change significantly.
Discussion: In general, it can be said that although the sleep deprivation in question did not impair the attention, concentration and effortfulness of the subjects, their shooting scores decreased significantly, and this decrease indicates the independence of the mental factors in relation to sleep deprivation of the subjects in this study.
