摘要
目的:探讨个体对社会暴力信息的注意偏向特点。方法:方便选取32名男性大学本科生为被试,运用自我评价方法对6对国际情绪图片系统中的暴力和非暴力图片,进行暴力信息等级评定,并采用EyelinkⅡ型眼动仪同时记录被试眼动数据。以兴趣区第一个注视点开始时间、兴趣区第一个注视点序列号、首次注视点在兴趣区比率、兴趣区注视点比率、兴趣区注视点总数、图片注视点总数、兴趣区注视时间、兴趣区最大瞳孔直径等作为眼动指标,并用配对t检验对数据结果进行统计分析。结果:被试在非暴力图片兴趣区第一注视点开始时间长于暴力图片,在兴趣区第一个注视点序列号大于暴力图片,在首次注视点在兴趣区比率小于暴力图片,在图片注视点总个数多于暴力图片,在兴趣区的注视时间多于暴力图片,在兴趣区瞳孔最大直径小于暴力图片,且非暴力图片与暴力图片相比均具有显著差异。但是兴趣区注视点总数差异无统计学意义。结论:社会暴力信息能够引起个体明显的情绪改变并吸引个体的注意,产生注意偏向。但是否影响个体注意的维持或注意解除有待进一步研究。
Objective: To explore the characteristics of human attention bias to social violent information. Methods: Thirty-two male college students were selected by convenience sample and asked to evaluate violent information of 6 pairs of pictures selected from International Affective Picture System. Their eye movements were also recorded and analyzed using Eyelink II eye tracking instrument, and analyse the data with Paired t test. The eye movement indexs inelueded first fixation time, first fixation index, first gaze ratio, fixation count, dwell time, and pupil size max. Results: The results showed that eye movements variables in interest area of violent pictures were significantly different with non-violent ones. First fixation time of violent pictures was longer than time of non-violent ones [ (492 ±405) ms vs. (374 ±342) ms] . First fixation index of violent pictures was more than of non-violent ones [ (3 ± 2) vs. (2 ± 1 ) ] . First gaze ratio of violent pictures was less than of non- violent ones [ (28 ± 39 )% vs. (49 ± 25 )% ] . Fixation count of violent pictures were more than of non-violent ones [ ( 12 ± 3 ) vs. ( 11 ± 2) ] . Dwell time of violent pictures was more than of non-violent ones [ ( 1847 ± 581 ) ms vs. (2063 ± 736) ms ] . Pupil size max of violent pictures were more than of non-violent ones [ ( 1772 ± 476) units vs. (2507 ±436) units] . But the variable of fixation count E (6 +2) vs. (6 ±2) ] of interest area of violent pictures was not significantly different with non-violent ones. Conclusion: The results indicate that social vio- lent informationcan arouse obvious emotional responses, attract people's attention and produce attentional bias. But whether the violent information can influence the maintaining of attention still needs further studies.
