Eye movements characteristics of image processing in self-rated depressed college students
Objective:To investigate the eye movement characteristics of non-emotional pictures and emotion-al pictures in college students with different self-rating levels of depression.Methods:The Baker Depression Ques-tionnaire(BDI-2)was used to select 20 college students in high score group(BDI-2 score≥ 18 points)and 20 col-lege students in low score group(BDI-2 score ≤2 points).In experiment 1 the different finding tasks were used to investigate the difference of eye movement features between the two groups when viewing non-emotional pic-tures.In experiment 2 the expression recognition tasks were used to investigate the difference of the eye movement features between the two groups when viewing emotional pictures.Results:The results of experiment 1 showed that when completing the judgment task,the fixation times of each interest area of non-emotional images was smaller in the high score group than in the low score group(P＜0.01).The results of experiment 2 showed that the reaction time was longer to sad faces than to happy faces in the high score group(P＜0.05),and the correct rate to sad faces was higher in the high score group than in the low score group(P＜0.05).For the eye interest area,the first fixation arrival time was earlier in the high score group than in the low score group(P＜0.001),and the first fixa-tion time and total fixation time were shorter in the high score group than in the low score group(Ps＜0.01).Con-clusion:College students with high self-rating level of depression show a decrease of interest when viewing non-e-motional pictures,and show an advantage in processing negative emotional information and avoiding eye gaze when viewing emotional pictures.
