چکیده
هدف تحقیق حاضر مقایسه رفتار جستجوی بینایی و دقت تصمیم گیری داوران ماهر و مبتدی بسکتبال بود. شرکت کنندگان در تحقیق 38 داور مرد بسکتبال بودند که در دو گروه ماهر و مبتدی تقسیم شدند (هر گروه 18 نفر). شرکت کنندگان در آزمون کلیپ ویدئویی (50 کلیپ در دو قسمت 25 تایی) شرکت کردند و تعداد و مدت تثبیت ها از طریق دستگاه ردیاب بینایی به همراه دقت تصمیم گیری برای هر شرکت کننده ثبت شد. برای مقایسه داده ها از آزمون تی مستقل و اندازه اثر استفاده شد. نتایج نشان داد که اختلاف معنی داری بین دو گروه در دقت تصمیم گیری و جود دارد اما بین تعداد و مدت تثبیت های دو گروه هیچ اختلاف معنی داری و جود ندارد. این نتایج نشان داد که احتمالا داوران ماهر نسبت به داوران مبتدی توانایی بیشتری برای استخراج اطلاعات مرتبط با تصمیم گیری مناسب از زمینه بینایی مشابه را دارند، که به آنها کمک می کند تا تصمیمات دقیق تری بگیرند.

چکیده [English]
This study aims to draw a comparison of Visual Search Behavior and Decision Making accuracy among expert and novice Basketball referees. 38 male referees took part in the research and were divided into two groups of experts and novices (Each group consisting of 18 people). Participants took part in a video test ( 50 clips in 2 section) in which the number of fixation, average fixation duration and their decision making accuracy was registered through a Visual Search device. t- Test and effect size was used to compare results. results showed that there is a significant difference between the two groups in their decision making accuracy, but there is no significant difference in their number of fixation and average fixation duration. Expert referees may be able to extract more relevant decision making information from the same visual field as compared to the novice referees that will help to make more accurate decisions.
