基于中医人格分型的网瘾交往障碍者抑制控制能力的ERP研究

Inhibitory control ability of ERP research on internet addiction disabilities based on personality types of traditional Chinese medicine

目的探讨不同人格分型的网瘾交往障碍者抑制控制能力的ERPs成分差异,揭示阴阳人格对抑制控制的影响及脑电生理学证据。方法采用网络成瘾临床诊断标准、人际关系综合诊断量表及五态性格量表筛选出偏阴人格组及偏阳人格组网瘾交往障碍者各16例。采用ERP技术,通过Go/Nogo研究范式检测两组被试前额叶执行控制功能,分析ERPs成分差异。结果偏阳和偏阴人格两组被试均成功诱发出了明显的N2和P3波形;两组被试P3成分分析,Nogo刺激较Go刺激均诱发出幅值更大、潜伏期更早的P3,Fcz电极位置诱发出的P3最大、Nogo效应最明显;两组被试差异表现在偏阳组被试存在显著的N2Nogo幅值效应,偏阴组被试不存在该刺激效应。结论与偏阳组相比,偏阴组网瘾交往障碍者在抑制控制机能(冲突信息的监测和行为反应抑制)上存在更大程度的损害。

Objective To explore the component difference of event-related potentials（ERPs） of the control ability of different personality types of internet addiction interpersonal barriers patients,and to reveal the electrophysiological evidence as well as the effect on inhibitory control ability. Methods A total of 32 patients with internet addiction interpersonal barriers who had Yin（n = 16） and Yang（n = 16） personality were selected according to the Clinical Diagnostic Criteria for Internet Addiction,Interpersonal Comprehensive Diagnostic Scale and Five-pattern Personality Inventory in this study. The prefrontal executive control function of the two groups was tested with Go / Nogo paradigm,and the differences of ERPs were analyzed. Results The N2 and P3 waves were successfully induced in the two types of personalities. Analysis of the composition of P3 indicated that,Nogo stimulation evoked a larger amplitude and earlier latency of P3 than Go stimulation; Fcz electrode induced the most powerful P3,with the most obvious Nogo effect. Thesubjects with Yang personality had significant N2 Nogo amplitude effect,while subjects with Yin personality had not.Conclusion Compared with subjects with Yang personality,those with Yin personality have poorer inhibitory control function on monitoring of and response to conflicting information.
