先前对狗的运动偏侧性的研究产生了一些相互矛盾的结果，在性别、时间和任务上的偏侧性不一致。目前的研究修改了已发表的食物检索和胶带去除测试，然后将其应用于43只狗。结果表明，50次食物检索任务（Kong (TM) test）的结果与100次观察结果一致。此外，在Kong （TM）和胶带去除试验期间的观察结果在观察者内部和之间都是一致的。Kong （TM）和Tape测试的侧化结果在品种和性别之间以及随着时间的推移通常是一致的，唯一的例外是Tape测试中的分类组和Kong （TM）测试中的侧化强度。在这项研究中，最令人感兴趣的是两种不同运动侧化任务的结果缺乏一致性。鉴于运动侧化被认为反映了大脑结构或功能的差异，任务结果的差异可能表明两项任务的复杂性不同。
Previous studies of motor laterality in dogs have produced some conflicting results, with inconsistencies in lateral biases across sexes, over time, and across tasks. The current study modified published food-retrieval and tape-removal tests before applying them to 43 dogs. It showed that results derived from 50 observations of a food-retrieval task (Kong (TM) test) were consistent with 100 observations. Further, observations during both Kong (TM) and the tape-removal tests were consistent both within and between observers. Lateralisation results from both the Kong (TM) and Tape tests were generally consistent between breeds and sexes and over time, the only exceptions being the categorical groups during the Tape test and the strength of lateralisation in the Kong (TM) test. Of greatest interest in this study was the lack of consistency between results from the two different motor lateralisation tasks conducted. Given that motor lateralisation is said to reflect differences in brain structure or function, differences in task results may indicate differing complexities of the two tasks.
