摘　　要：目的:考查不同自评抑郁水平大学生加工非情绪图片、情绪图片的眼动特征。方法:使用贝克抑郁问卷(BDI-2)筛选高分组大学生(BDI-2得分≥18分)、低分组大学生(BDI-2得分≤2分)各20名。实验1使用找不同任务,考察两组观看非情绪图片时的眼动特征差异。实验2使用表情识别任务,考察两组观看情绪图片时的眼动特征差异。结果:实验1结果显示,在完成判断任务时,高分组对非情绪图片各兴趣区的注视次数少于低分组(P<0.01)。实验2结果显示,高分组对悲伤面孔判断的反应时长于高兴面孔(P<0.05),高分组对悲伤面孔判断的正确率高于低分组(P<0.05);高分组对眼睛兴趣区的首次注视到达时间早于低分组(P<0.001),首次注视时间、总注视时间均短于低分组(P<0.001或P<0.01)。结论:自评抑郁水平高分组大学生观看非情绪图片时表现出兴趣减退的特征,观看情绪图片时表现出对负性情绪信息的加工优势和对眼睛注视的回避。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.
