Lateralization of motor food skills has been investigated on 77 adult white rats. The predominance for the left anterior extremity while carrying out food was found in 53.5% of rats, the right extremity--in 36.4% of rats. 10.3% of rats belonged to ambidexters. Prevalence of using left extremity was peculiar to the females as against the male ones. Three generations of left-handed rats obtained by crossing have been followed. Rats making use of the left extremity to take out food predominated in the second and third generates.
对77只成年白鼠的运动取食技能偏侧化进行了研究。在53.5%的白鼠中发现取食时左前肢占优势,右前肢占优势的白鼠占36.4%。10.3%的白鼠属于左右肢并用型。与雄性白鼠相比,雌性白鼠更倾向于使用左肢。对通过杂交获得的三代左撇子白鼠进行了跟踪研究。在第二代和第三代白鼠中,利用左肢取食的白鼠占多数。
