Joint go and no-go effects (joint Simon effects; JSEs) are considered to have a stimulus-response compatibility effect on joint reaction time tasks (joint Simon task) caused by the presence of other people. Additionally, JSEs are known to be associated with various social factors and are therefore a potential clinical marker for communicative function; however, the relationship with the personality that is associated with communication skills remains unclear. In this study, we focused on the association between JSE and personality traits. Thirty Japanese participants (fifteen women) were recruited. First, personality trait scores were obtained using the Japanese version of the ten-item personality inventory before the experiment. Second, we measured reaction times in the joint Simon task and single go and no-go tasks with the go signal presented on the congruent and incongruent sides. At last, we analyzed the association between reaction times and personality traits by using Spearman's correlation analysis. As a result, we observed two pairs with significant correlations: JSE and neuroticism and short reaction times in the joint condition and agreeableness. In conclusion, we identified potential psychological markers associated with the joint Simon task. These findings may lead to an additional hypothesis regarding the neurobiological mechanisms of JSEs.
联合执行与停止效应（联合西蒙效应；JSEs）被认为对由他人在场引起的联合反应时任务（联合西蒙任务）具有刺激-反应兼容性效应。此外，JSEs已知与各种社会因素相关，因此是沟通功能的潜在临床标志物；然而，与沟通技能相关的人格之间的关系仍不清楚。在本研究中，我们关注JSE与人格特质之间的关联。招募了30名日本参与者（15名女性）。首先，在实验前使用日语版的十项人格量表获得人格特质分数。其次，我们在联合西蒙任务以及单执行和停止任务中测量反应时，其中执行信号呈现在一致和不一致的一侧。最后，我们使用斯皮尔曼相关分析来分析反应时与人格特质之间的关联。结果，我们观察到两对具有显著相关性：JSE与神经质以及联合条件下的短反应时与宜人性。总之，我们确定了与联合西蒙任务相关的潜在心理标志物。这些发现可能会引出关于JSEs神经生物学机制的另一个假设。
