| Outline of Research at the Start |
本研究の目的は運動課題において２人が１人よりも高いパフォーマンスになる” Two head are better than one 効果（2HBT1効果）”の生じる条件やメカニズムについて検討することである。実験Ⅰでは、２人の参加者が力を発揮し、その総和を持続的、分離的、周期的に目標値に一致させる３つ課題を用いて、2HBT1効果が力発揮のタイミングの有無によって影響されるかどうかを検討する。さらに、実験Ⅱは実験Ⅰで用いた３つ課題中に脳波計を用いて脳活動を検討し、タイミング制御を必要とする個人間の力発揮課題において2HBT1効果が生じる際の神経系のメカニズムを明らかにする。

| Outline of Final Research Achievements |
In the present study, to examine the "two heads are better than one effect" (2HBT1 effect) when timing control is required, we used a task in which two participants performed continuous, discrete, and periodic force productions and matched the sum of these forces to a target force. The results showed that there was no significant main effect of the one-person task (individual task) and the two-person task (joint task) for the continuous force production, but the joint task had a lower error than the individual task for the discrete and periodic force productions. Thus, the 2HBT1 effect did not occur in the continuous force production, which did not require timing control, but it did occur the discrete and periodic force productions, which did require timing control. Thus, the 2HBT1 effect did not occur in the continuous force production without timing control, but it did occur in the discrete and periodic force productions with timing control.
