In the present study, ten pairs of two participants simultaneously adopted both complementary and synchronous strategies and the two strategies facilitated the joint action. The pairs produced periodic isometric forces such that the sum of forces produced by them was the target force cycling between lower levels of maximum voluntary contraction with an interval of 1000 ms(joint task), while individuals alone produced the same target forces with the right hand(individual task). When the total force was visible, while the correlation between forces produced by two participants was highly negative, the coherence between the forces was highest at the target interval, indicating that the pairs simultaneously adopted both strategies. Surprisingly, the joint task exhibited a less variable force and interval than the individual task, indicating that the joint action exhibited larger performance gains than the individual action.
