Lateral preference is influenced by many different factors. Although studies that assessed handedness contributed greatly to our understanding of the phenomenon, looking to other dimensions of motor laterality, such as lower limbs, trunk, visual and hearing preference, may be an interesting strategy to further advance in the field. Comparing different age groups with a complete inventory also contributes to understanding the ageing impact on these variables. Our aim, therefore, was to assess six motor laterality dimensions in younger adults and older people. Two hundred subjects participated in this study (102 adults, 30.6 ± 11.2 years old, and 98 elders, 70.4 ± 7.22 years old) and lateral preference was assessed by the Global Lateral Preference Inventory. We verified significant differences between groups in all dimensions, except the visual one, with proportionally stronger right preference in the older group. Compared to other dimensions, higher frequency of ambidexterity was observed in trunk, hearing and visual preference for both groups. These results might indicate that lateral preference is, indeed, multifactorial, being affected by ageing, task complexity and other possible related aspects.

横向优先受许多不同因素的影响。尽管评估惯用性的研究对我们对这种现象的理解做出了很大贡献，但寻找运动侧向性的其他方面（例如下肢，躯干，视觉和听觉偏好）可能是在该领域进一步发展的有趣策略。将不同年龄段的人群与完整的清单进行比较，也有助于理解老化对这些变量的影响。因此，我们的目的是评估年轻人和老年人的六个运动侧向度。共有200名受试者（102名成年人，年龄为30.6±11.2岁，98名老年人，年龄为70.4±7.22岁）参加了这项研究，并通过全球横向偏爱量表评估了横向偏爱。我们验证了各个组之间各个维度之间的显着差异，但视觉上除外，在年长的人群中，他们的权利偏好会成比例地增加。与其他维度相比，两组在躯干，听觉和视觉偏好方面都出现了更高的歧义频率。这些结果可能表明，横向偏爱确实是多因素的，受年龄，任务复杂性和其他可能相关方面的影响。
