اثر رنگهاي اصلي بر ادراك عمق نوجوانان مبتلا به تالاسمي ماژور و مقايسه با نوجوانان سالم

The effect of primary colors on depth perception in patients with thalassemia major and comparison with healthy adolescents

اين مطالعه با هدف اثر رنگ‌هاي اصلي بر ادراك عمق نوجوانان مبتلا به تالاسمي ماژور و مقايسه‌ي آن با نوجوانان سالم انجام شده‌است. روش اين مطالعه، نيمه‌تجربي بوده و نمونه شامل 18 نفر بيمار تالاسمي ماژور و 18 نفر افراد سالم در محدوده‌ي سني 13 تا 17 سال (41/1 ±33/15) بودند كه به روش نمونه‌گيري در دسترس انتخاب شدند. آزمودني‌ها در هر رنگ سه نوبت، به‌كمك دستگاه ادراك عمق، رنگ و شكل مورد ارزيابي قرار گرفتند. ميانگين هر سه نوبت به‌عنوان نمره‌ي ادراك عمق افراد در آن رنگ مورد استفاده قرار‌گرفت. آناليز واريانس در اندازه‌هاي تكراري نشان داد كه بين رنگ‌هاي اصلي در دوگروه، تفاوت معني‌داري وجود دارد (0001/0 = pو 564/62= (34 و2)F). همچنين اثر اصلي گروه معني‌دار است ( 0001/0= P و334/14= (34و1)F). بر اساس نتايج به‌دست‌آمده، با توجه به طول موج‌هاي مختلف، رنگ‌هاي مختلف ادراك عمق متفاوتي دارند و رنگ آبي در زمينه‌ي زرد بيشترين خطا را دارد. با توجه به اهميت ادراك عمق و رنگ در رفتار حركتي انسان، در اين خصوص بايد مطالعات بيشتر صورت گيرد.

The most severe form of thalassemia is beta thalassemia in which a personʹs life is necessarily required regular blood transfusions and medical care. With starting treatments such as desferrioxamine injection and repeated blood transfusions, several complications is created in the patientʹs vital organs, including eyes, the most important member of sensory. The vision is considerably more sensitive than other senses in perceptual - motor performances and it is also sensitive to details, depth and color. As a result, it has a decisive role in movement control. This study has been conducted to draw the effect of primary colors on depth perception in patients with thalassemia major and comparison with healthy adolescents. This method is semi-experimental and the sample was 18 thalassemia patients and 18 healthy subjects in the age range 13 - 17 years (15/33± 1/41) who were selected through available sampling. These subjects have been evaluated three times in each color by the depth, color & shape perception apparatus. The average of these three times tests was used as depth perception scores of people in that color. Results in repeated measures ANOVA showed that there are significant differences between the primary colors in both groups (p = 0 /0001, df=34 and F (2, 34) = 62/564). Also the real effect of group was significant (p = 0 /0001, df=34 and F (1, 34) = 14/334). According to different wavelengths, different colors have different depth perception, and the blue has the greatest error in yellow background. It requires more studies in this regard due to the importance of depth and color perception in human motor behavior.
