摘要 目的探讨自闭特质群体疼痛共情的特点及神经加工机制。方法收集自闭特质高分组21例和低分组22例,完成疼痛共情任务并记录被试的反应时及正确率,脑电仪同时记录其ERP数据。结果(1)行为学结果显示,两组被试的人际指针反应问卷得分在观点采择[(23.71±4.16)分,(26.95±3.24)分]、共情性关心[(24.10±4.04)分,(26.36±2.82)分]以及个人痛苦因子[(24.19±3.59)分,(19.82±3.96)分]上的差异有统计学意义(t=-2.86,P〈0.01;t=-2.14,P〈0.05;t=3.79,P〈0.01),想象力因子差异无统计学意义(t=-1.50,P〉0.05);(2)行为学结果显示,疼痛共情任务中两组被试的反应时和正确率的任务类型主效应有统计学意义(F(1,4)=24.21,P〈0.01;F(1,4)=152.10,P〈0.01),反应时和正确率的情绪类别以及组别主效应无统计学意义(F(1,4)=1.11,P〉0.05,F(1,41)=0.29,P〉0.05;F(1,41)=3.20,P〉0.05,F(1.41)=0.14,P〉0.05)。(3)ERP结果显示,两组被试N2波幅上情绪类型、任务类型以及组别主效应均未达到显著性水平(F(1.41)=0.04,P〉0.05;F(1.41)=0.08,P〉0.05;F(1.41)=3.86,P〉0.05);P3波幅上情绪类型主效应达到显著性水平(F(1.41)=8.27,P〈0.01),任务类型以及组别主效应未达到显著性水平(F(1.41)=2.48,P〉0.05,F(1.41)=0.25,P〉0.05);LPP波幅上情绪类型、任务类型以及组别主效应达到显著性水平(F(1.41)=32.07,P〈0.01;F(1.41)=8.63,P〈0.01;F(1.41)=4.73,P〈0.05)。结论自闭特质高低分组问疼痛共情能力存在差异,且主要表现在晚期认知加工过程中。 Objective To study the features and neural mechanism of pain empathy in autistic indi- viduals. Methods Totally 21 subjects with high level autistic traits and 22 subjects with low level autism traits completed the pain empathy task, recording RT and accuracy automatically. The event-related potentials (ERPs) were recorded by Neuroscan system simultaneously. Results (1)From the behavioral results, the IRI scores of the two groups had significant differences in the factors of perspective taking ( (23.71±4.16) vs (26.95±3.24) ) , empathy concerning ( (24.10±4.04) vs ( 26.36±2.82 ) ) and personal distress ( ( 24.19± 3.59) vs (19.82±3.96) ) (t=-2.86,P〈0.01;t=-2.14,P〈0.05;t=3.79,P〈0.01). The factor of fantasy of the two groups didn't exit significant differences (t=- 1.50 ,P〉0.05). (2) According to the behavioral result of pain empathy test, the main effect of task type in reaction time and accuracy of the two groups had signifi- cant difference (F(1.41) = 24.21 ,P〈0.01 ; F(1.41) = 152.10,P〈0.01) ,but the main effect of emotion type and group didn't reach significant level (F(1.41)= 1.11 ,P〉0.05,F(1.41)= 0.29,P〉0.05;F(1.41)= 3.20,P〉0.05, (1.41) = 0.14,P〉0.05). (3)From the results of ERP, the main effect of emotion type, task type and group didn't reach the significant level in the N2 amplitude of the two groups ( F(1.41) = 0.04,P〉0.05 ; F(1.41) = 0.08, P〉 0.05 ;F(1.41) = 3.86,P〉0.05). The main effect of emotion type had significant difference in the P3 amplitude of the two groups( F(1.41) = 8.27 ,P〈0.01 ) ,but there was no significant difference in the main effect of task type and group ( F(1.41) = 2.48,P〉0.05, F(1.41) = 0.25,P〉0.05). It had significant difference in LPP amplitude inthe main effect of emotion type, task type and group( F(1.41)= 32.07, P〈0.01 ;F(1.41)= 8.63 ,P〈0.01;F(1.41)= 4.73 ,P〈0.05). Conclusions There are d
