Preference was studied of one of the forelimbs during performance of different manipulating movements in white rats. High degree of "handedness" was observed in all studied movements. However it was not absolute--no animals performed all movements by one and the same limb. Degree and character of "handedness" were different for different movements, though the number of "righthanded" rats in most tests as a whole exceeded the number of "lefthanded" ones. The "handedness" depends on the individuality of the animal, the character of the motor task, learning and interference of different motor tasks during training.
研究了白鼠在进行不同操作动作时对一侧前肢的偏好。在所有研究的动作中都观察到了高度的“用手习惯”。然而，这并非绝对——没有动物用同一肢体完成所有动作。不同动作的“用手习惯”程度和特征各不相同，尽管在大多数测试中，“右利手”大鼠的数量总体上超过了“左利手”大鼠。“用手习惯”取决于动物的个体性、运动任务的特征、学习以及训练过程中不同运动任务的干扰。
