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—relatedpotential）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—700ms，3种实验条件主效应显著[F（2，68）=28．78，P〈0．05，s=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〈0．05，8=0．278；F（4，136）=17．64，P〈0．05，s=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 condi- tions： attachment, emotion-nonattachment and neutral conditions. Results Between the 320 -700 ms after the stimu- lus appeared, the main effects of the three conditions were significant（F（2,68） =27. 676, P 〈0. 05, e =0. 449） and the interaction between the three condition and left-right brain hemisphere was significant. The interaction between the three condition and frontal-central-parietal brain area was also significant （F（2,68） = 12. 439, P 〈 0. 05, ~ = 0. 268, F （4,136） = 15. 504, P 〈 0. 05, ~ = 0. 313）. Conclusion This experiment result supports the hypothesis that attach- ment-related information can activate the attachment system.
