摘要：

目的:揭示依恋性情绪信息与非依恋性情绪信息对依恋系统的激活。方法:采用ERP(event-related potential)技术手段,基于依恋性情绪、非依恋性情绪和中性3种实验条件,测量被试在这3种实验条件下后正电位(LPP)波幅的差异。结果:在句子呈现后320~700 ms,3种实验条件主效应显著[F(2,68)=28.78,P<0.05,ε=0.452]。3种实验条件与左右脑以及前中后脑分布交互作用显著[F(2,68)=13.47,P<0.05,ε=0.278;F(4,136)=17.64,P<0.05,ε=0.314]。多重比较发现,依恋性情绪条件的波幅显著大于非依恋性情绪,非依恋性情绪显著大于中性实验条件。简单效应分析发现,右脑分布的依恋性情绪条件与非依恋性情绪的LPP波幅差异大于左脑。前部和中部的依恋性情绪条件与非依恋性情绪的LPP波幅差异大于后部。结论:依恋性情绪信息与非依恋性情绪信息有不同的脑激活模式,依恋性情绪信息促进依恋系统激活。

Objective To investigate the activation the adult attachment system by the emotion-related information.Method This experiment adopted the ERP(event-related potential) technology and set up three experimental conditions: attachment,emotion-nonattachment and neutral conditions.Results Between the 320~700 ms after the stimulus appeared,the main effects of the three conditions were significant(F(2,68)=27.676,P<0.05,ε=0.449) and the interaction between the three condition and left-right brain hemisphere was s...
