چکیده
پژوهش حاضر با هدف بررسی رابطۀ بین سطح داوری و نوع رشتۀ ورزشی با میزان خطای ادراک عمق داوران ورزشی در رنگهای سرد و گرم انجام گرفت. بدینمنظور 30 داور ورزشی شامل 15 داور از رشتههای گروهی و 15 داور از رشتههای انفرادی از پنج درجۀ داوری (درجه سه، درجه دو، درجه یک، درجۀ ملی و درجۀ بینالمللی) و 15 فرد غیرورزشکار به روش نمونهگیری دردسترس انتخاب شدند. میانگین سنی نمونۀ آماری (93/11±)53/38 سال بود. ادراک عمق شرکتکنندگان در هر رنگ (آبی، سبز، قرمز و نارنجی) در دو کوشش متوالی به کمک دستگاه ادراک عمق، رنگ و شکل ارزیابی شد. میانگین این هشت کوشش به‌عنوان نمرۀ ادراک عمق کل افراد در نظر گرفته شد. میانگینرنگهایآبیو سبزبهعنوانرنگهایسردو میانگینرنگهایقرمزونارنجیبهعنوانرنگهایگرمثبتشد. برای تحلیل دادهها از ضریب همبستگی اسپیرمن، تحلیل واریانس یکطرفه و آزمون تعقیبی بونفرونی استفاده شد. نتایج نشان داد همبستگی معناداری بین سطح داوری با میزان خطای ادراک عمق وجود ندارد؛ همچنین یافتهها بر نبودِ تفاوت معنادار در میزان خطای ادراک عمق بین داوران رشتههای گروهی و انفرادی دلالت داشت. بااینحال، این دو گروه بهطور معناداری ادراک عمق بهتری نسبت به گروه غیرورزشکار داشتند. همچنین در مقایسۀ خطای ادراک عمق در رنگهای سرد و گرم بین سه گروه نیز، داوران رشتههای گروهی و انفرادی بهطور معناداری در رنگهای سرد نسبت به افراد غیرورزشکار برتر بودند. بهطورکلی این مطالعه نشان میدهد که مهارتهای بینایی ممکن است بین داوران ورزشی و افراد غیرورزشکار متفاوت باشد.

چکیده [English]
The aim of present study was to investigation relationship between refereeing level and type of sport field with sport referees’ amount of depth perception error in cold and warm colors. To do so, 30 referees including 15 referees of team fields and 15 referees of individual fields with different referee's degree (A, B, C, National degrees and International degrees) and 15 non-athlete individuals were selected using availability sampling method. Average age of statistical sample was 38.53(±11.93). Subjects' depth perception in each color (blue, green, red & orange) have been evaluated in two continues tries by the depth, color and shape perception apparatus. The average of these eight tries was used as individuals' depth perception score. The average of blue and green colors was used as cold colors and the average of red and orange colors was used as warm colors. Data were analyzed using Spearman correlation coefficient, one-way analysis of variance (ANOVA) and Bonferroni post-hoc test. Results of present study indicated that there was no significant correlation between refereeing level and error amount of depth perception. Also, there was no significant difference between referees of team and individual fields in error amount of depth perception. However, sport referees were significantly better than non-athlete individuals. Also, in comparison the depth perception error in cold and warm colors between three groups, referees of team and individual fields were significantly better than non-athlete individuals in cold colors. Generally, this study shows that visual skills may be different between sport referees and non-athlete individuals.
