摘要

目的探讨抑郁症患者对不同情绪面孔的认知加工随时间的变化特征。方法选择抑郁症患者29例(患者组)，正常人30例(对照组)。受试者可以自由地观看积极、悲伤、威胁和中性的面部刺激。在观看过程中采集眼球运动数据，比较两组被试在识别四种情绪面孔时的注意偏差在时间上的差异。分析两组间注意力的时间变化趋势。结果患者组与对照组注视时间0 ~ 2 s((10.39±1.83)ms，(9.63±1.28)ms)， 2 ~ 4 s((12.61±2.34)ms，(11.21±3.00)ms)， 4 ~ 6 s((12.26±3.11)ms，(10.47±4.06)ms)，差异均无统计学意义(P < 0.05)。在6 ~ 8 s((12.64±3.42)ms，(8.90±4.02)ms)， 8 ~ 10 s((12.55±4.19)ms，(9.36±4.02)ms)内，患者组注视时间明显长于对照组(P<0.01)。患者组正面注视时间0 ~ 2 s((12.07±2.65)ms，(14.50±3.54)ms)、2 ~ 4 s((10.69±3.26)ms，(14.66±5.25)ms)、4 ~ 6 s((10.11±4.24)ms，(15.43±8.02)ms)、6 ~ 8 s((9.39±5.12)ms，(16.88±9.60)ms)、8 ~ 10 s((9.45±4.94)ms，(16.63±10.15)ms)显著低于对照组(P均<0.01)。结论抑郁症患者在认知加工的后期倾向于注意负性刺激，而在认知加工的早期倾向于注意正性刺激。抑郁症患者对情绪刺激的认知加工表现为对消极刺激的注意持续时间增加，对积极刺激的注意持续时间减少。关键词:抑郁症;注意力偏见;人脸识别;眼动

Time course of attention bias in face recognition of patients with depression

Objective To explore the characteristics of cognitive processing over time in recognition of different emotional faces in patients with depression. Methods Totally 29 patients with depression(patient group) and 30 normal control (control group)were selected.Subjects freely viewed positive, sad, threatening and neutral facial stimuli.Eye movement data were collected during the process of watching, and the differences of attention bias in time when the two groups of subjects recognized the four emotional faces were compared.The temporal variation trend of attention between the two groups was analyzed. Results There was no significant difference in the fixation duration between the patient group and the control group in 0-2 s((10.39±1.83)ms, (9.63±1.28)ms), 2-4 s((12.61±2.34)ms, (11.21±3.00)ms), 4-6 s ((12.26±3.11)ms, (10.47±4.06)ms)(all P>0.05). Within 6-8 s((12.64±3.42)ms, (8.90±4.02)ms), 8-10 s((12.55±4.19)ms, (9.36±4.02)ms), the fixation duration in the patient group was significantly longer than that in the control group (P<0.01). The fixation time of the positive faces in the patient group in 0-2 s ((12.07±2.65)ms, (14.50±3.54)ms), 2-4 s((10.69±3.26)ms, (14.66±5.25)ms), 4-6 s((10.11±4.24)ms, (15.43±8.02)ms), 6-8 s((9.39±5.12)ms, (16.88±9.60)ms), 8-10 s ((9.45±4.94)ms, (16.63±10.15)ms) was significantly lower than that in the control group (all P<0.01). Conclusion Patients with depression tend to pay attention to negative stimuli in the later stage of cognitive processing, while the attention to positive stimuli decreases in the early stage of cognitive processing.Cognitive processing of emotional stimuli in patients with depression is manifested as increased attention duration of negative stimuli and decreased attention duration of positive stimuli.

期刊介绍： "Chinese Journal of Behavioral Medicine and Brain Science" (CN 37-1468/R, ISSN 1674-6554) is a national academic journal under the supervision of the National Health Commission, sponsored by the Chinese Medical Association and Jining Medical College. The journal was founded in June 1992 and was formerly known as "Chinese Journal of Behavioral Medicine" (1992-1993) and "Chinese Behavioral Medical Science" (1994-2008). In 2009, it was renamed "Chinese Journal of Behavioral Medicine and Brain Science" with the approval of the State Administration of Press, Publication, Radio, Film and Television. The purpose of "Chinese Journal of Behavioral Medicine and Brain Science" is to implement the health and health policies of the Party and the State, implement the principle of combining theory with practice and popularization and improvement, and reflect the major progress in the theory and practical application of behavioral medicine and brain science in my country. It publishes academic papers and scientific research results in the field of behavioral medicine and brain science in my country, and has columns such as monographs/reviews, basic research, clinical research, health prevention, methods and techniques, psychological behavior and evaluation, and systematic evaluation.
