Motor laterality is quite often studied in non-human primates, but rarely has been investigated within ungulates. The aim of the study was to use the naturally occurring splay behavior in giraffe as a method to look for the presence of laterality. Four male giraffes housed at Zoo Atlanta were watched for three months, recording their first leg moved to begin the splay posture and the total number of leg movements to achieve a secure stance. All four giraffe significantly moved their left leg first to begin the stance, which suggests at least individual level laterality. However, using the number of leg movements overall, the last leg moved was only significant in one individual.
运动偏侧性在非人类灵长类动物中经常被研究，但在有蹄类动物中却很少被调查。本研究的目的是利用长颈鹿自然出现的叉开腿姿势行为，作为一种寻找偏侧性存在的方法。对圈养在亚特兰大动物园的四只雄性长颈鹿进行了为期三个月的观察，记录它们开始叉开腿姿势时首先移动的腿，以及为达到稳定姿势而进行的腿部移动总数。所有四只长颈鹿在开始姿势时都显著地首先移动左腿，这表明至少在个体水平上存在偏侧性。然而，从总体腿部移动次数来看，最后移动的腿仅在一只个体中具有显著性。
