经颅交流电刺激对健康人心理理论的干预研究

Effects of transcranial alternating current stimulation on theory of mind in healthy person

目的探究经颅交流电刺激对健康人心理理论能力的影响。方法采用高精度经颅交流电刺激仪器干预健康大学生右侧颞顶联合区,通过简单心理理论测验和复杂心理理论测验反应时指标来衡量健康人心理理论能力。结果真假刺激组在经颅交流电刺激干预前简单心理理论和复杂心理理论差异均无统计学意义,3种物理控制维度也均未发现显著差异。简单心理理论测验和复杂心理理论测验均显示在经颅交流电刺激干预后,真假刺激组前后测反应时明显降低,真刺激组下降更明显,真刺激组后测反应时显著低于假刺激组。结论经颅交流电刺激可以有效改善健康人心理理论能力。

Objective To explore the effects of transcranial alternating current stimulation on theory of mind in healthy subjects.Methods High precise transcranial alternating current stimulation instrument was used to intervene the right temporoparietal junction area of healthy college students.Their theoretical abilities were measured by simple and complex theory of mind tests.Results There was no significant difference in the simple and complex theory of mind tests in the real and shamed stimulation group before transcranial AC stimulation,and no significant difference was found in three physical control dimensions.According to simple or complex psychological theory tests,the reaction remarkably weakened in both groups after intervention,while more decreases were found in the real stimulation group.After intervention,the real stimulation group showed remarkable reduced reaction compared with the shamed stimulation group.Conclusions Transcranial alternating current stimulation can improve the theory of mind in healthy person.
