摘要

灵长类动物的手侧化已经在各种情况下得到了广泛的研究,并开始在其他物种和器官中进行研究,以了解不同任务下手侧化的进化。在大象中,主要在喂食和社会环境中,在自由的条件下,观察到大象鼻子运动的方向。然而,关于任务复杂度对主干横向性的影响,目前所知甚少。在这项研究中,我们比较了两种情况下的躯干偏侧:标准化和自由。我们在一个打开的活板门的每一边给六头非洲象提供颗粒,以创造一个约束环境,并报告了不同的行为和它们的方向。此外,我们观察了同样的个体在自由条件下,并注意到他们的躯干使用的侧化。我们发现,在标准化和自由条件下,所有大象都有一个共同的右侧偏好。这种偏倚在我们的约束任务中更强,为任务复杂性理论增加了证据。最后,我们在有关大象的文献中描述了侧面性的新行为,例如用鼻子捏、收集或探索。

Analogous laterality in trunk movements in captive African elephants: A pilot study.

Lateralization of hand use in primates has been extensively studied in a variety of contexts, and starts to be investigated in other species and organs in order to understand the evolution of the laterality according to different tasks. In elephants, the orientation of the movements of the trunk has been observed mainly in feeding and social contexts, in free conditions. However, little is known about the influence of task complexity on trunk laterality. In this study, we compared the lateralization of the trunk in two conditions: standardized and free. We offered granules to six African elephants on each side of an opened trapdoor to create a constraining environment and reported the different behaviours employed and their orientation. In addition, we observed the same individuals in free conditions and noted the lateralization of the use of their trunk. We revealed a common right side preference in all our elephants, both in standardized and free conditions. This side bias was stronger in our constraining task, adding evidence for the task complexity theory. We finally described laterality in new behaviours in the literature on elephants, such as pinching, gathering or exploration with the trunk.

期刊介绍: Laterality: Asymmetries of Body, Brain and Cognition publishes high quality research on all aspects of lateralisation in humans and non-human species. Laterality"s principal interest is in the psychological, behavioural and neurological correlates of lateralisation. The editors will also consider accessible papers from any discipline which can illuminate the general problems of the evolution of biological and neural asymmetry, papers on the cultural, linguistic, artistic and social consequences of lateral asymmetry, and papers on its historical origins and development. The interests of workers in laterality are typically broad.
