在许多物种中，与双侧个体相比，表现出偏侧手/爪使用（即优先使用右爪或左爪）的个体在新情况下表现出更积极主动的态度。在目前的研究中，我们使用了一个既定的测试，以评估优先爪子使用的狗（孔测试），然后比较了性能的双边和偏侧的狗，以及左与右爪狗在一个新的操纵问题解决任务。结果显示，双侧和偏侧的狗的比例相等，但与预测相反，非偏侧的狗在测试试验中更快地访问该设备。右爪和左爪狗之间没有差异。结果进行了讨论，与以前的研究偏侧化。(C)2013爱思唯尔有限公司版权所有。
In a number of species, individuals showing lateralized hand/paw usage (i.e. the preferential use of either the right or left paw) compared to ambilateral individuals have been shown to be more proactive in novel situations. In the current study we used an established test to assess preferential paw usage in dogs (the Kong test) and then compared the performance of ambilateral and lateralized dogs as well as left- vs. right-pawed dogs in a novel manipulative problem solving task. Results showed an equal proportion of ambilateral and lateralized dogs but contrary to predictions non-lateralized dogs were faster at accessing the apparatus in test trials. No differences emerged between right- and left-pawed dogs. Results are discussed in relation to previous studies on lateralization. (C) 2013 Elsevier B.V. All rights reserved.
