Research on six behavioral traits of lateral functional dominance in the Muya,Ersu, Bajia and Kongge peoples in China

Six behavioral traits of lateral functional dominance(hand clasping, handedness, arm folding, foot preference, leg folding and stride type) were investigated in the Ersu, Muya, Kongge and Bajia of Sichuan and Yunnan provinces. The results were as follows. A preference for the right side versus the left side in four ethnic groups except for arm folding of the Ersu, Muya and Bajia. There was no sexual difference in four ethnic groups, but there were differences between Muya, Ersu and Bajia in hand clasping, and in arm folding between the Muya and Kongge. There was a higher correlation among the six behavioral traits in the Bajia.
