The distinct theta rhythm in the frontal midline area during a performance of mental tasks has been called Fm theta. However, Fm theta shows individual differences in its appearance. The relationship between the appearance of Fm theta and the subject personality was investigated in the present study. Forty male university students performed an arithmetic addition test for 5 min daily during three consecutive days and their EEGs were recorded during the test. They also completed the Maudsley Personality Inventory (MPI) and the Taylor Manifest Anxiety Scale (MAS) after the EEG recording on the last day. The subjects who obtained low scores on the anxiety scale of MAS, high scores on the extraversion scale of MPI and low scores on the neuroticism scale of MPI showed larger amounts of Fm theta. On the other hand, those subjects who showed high scores on the anxiety scale, low scores on the extraversion scale and high scores on the neuroticism scale showed smaller amounts of Fm theta or none. These results suggest that the appearance of Fm theta is closely related to the subject personality traits.
在执行心理任务期间，额中线区域出现的独特θ节律被称为Fmθ。然而，Fmθ的出现存在个体差异。本研究调查了Fmθ的出现与受试者个性之间的关系。40名男性大学生连续三天每天进行5分钟的加法算术测试，并在测试过程中记录他们的脑电图。在最后一天脑电图记录后，他们还完成了莫兹利个性问卷（MPI）和泰勒显性焦虑量表（MAS）。在MAS焦虑量表上得分低、MPI外向性量表上得分高且MPI神经质量表上得分低的受试者表现出较多的Fmθ。另一方面，那些在焦虑量表上得分高、外向性量表上得分低且神经质量表上得分高的受试者表现出较少的Fmθ或根本没有。这些结果表明，Fmθ的出现与受试者的个性特征密切相关。
