摘　　要：目的研究情感忽视儿童在Stroop色词任务下行为学及事件相关电位P300特点,探讨其抑制控制功能。方法对河南省三门峡市某初中一年级学生进行整群抽样,被抽取的3个班级的学生接受标准瑞文推理测验和儿童被忽视量表(CNS)评定,筛选出147名符合条件的学生。根据CNS情感忽视因子评分,将位于前后27%评分范围内的学生分别分为情感忽视组(n=40)和对照组(n=40)。两组儿童均完成Stroop色词任务,并采集脑电数据,比较两组反应时、正确率以及P300波幅和潜伏期。结果情感忽视组CNS总评分、安全忽视、交流忽视、躯体忽视及情感忽视因子评分均高于对照组(t=15.003、4.301、11.495、4.803、23.957,P均<0.01)。执行矛盾任务时,情感忽视组反应时长于对照组[(879.02±101.52)ms vs.(756.93±113.91)ms,t=5.061,P<0.01],P300波幅低于对照组[(3.97±1.12)μV vs.(8.71±1.24)μV,t=-17.976,P<0.01],潜伏期长于对照组[(361.81±39.69)ms vs.(301.35±33.67)ms,t=7.346,P<0.01]。结论情感忽视儿童处理矛盾任务时的反应时长、P300潜伏期长、波幅低,提示其可能存在抑制控制障碍。Objective To investigate the P300 evoked by Stroop Color Word Task in children with emotional neglect,and to explore their implication for inhibition control.Methods A cluster sampling was conducted for the first grade students of a middle school in Sanmenxia City,Henan Province.The students from 3 classes were assessed by standard Raven reasoning test and Child Neglect Scale(CNS),and a total of 147 eligible students were screened out.Children were divided into the emotional neglect group(n=40)and the control group(n=40)according to the 27%before and after the score of CNS emotional neglect factor.Both groups completed the Stroop Color word task,and EEG data were collected to compare the response time,accuracy,amplitude and latency of P300 between the two groups.Results The CNS total score and the scores of safety neglect,communication neglect,physical neglect and emotional neglect factors in the emotional neglect group were significantly higher than those in control group(t=15.003,4.301,11.495,4.803,23.957,P<0.01).The average reaction time in the incongruent task of emotional neglect group was significantly longer than that in the control group[(879.02±101.52)ms vs.(756.93±113.91)ms,t=5.061,P<0.01].Under incongruent task,the average amplitude of P300 in emotional neglect group was lower than that of the control group[(3.97±1.12)μV vs.(8.71±1.24)μV,t=-17.976,P<0.01].The average latency of P300 of emotional neglect group was longer than that of the control group[(361.81±39.69)ms vs.(301.35±33.67)ms,t=7.346,P<0.01].Conclusion Under incongruent task,children with emotional neglect had longer response time,longer latency and lower amplitude of P300,which suggested that children with affective neglect may have inhibition and control disorder.
