Abstract
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.
