The goal of the present study was to compare the choice of foot of right-footed children with varying strengths of foot preference when performing two tasks of different levels of complexity at three spatial locations. 30 right-footed children were tested. The results showed that the general tendency to use one's preferred foot to interact with an object is more or less pronounced depending on the object's location and the complexity of the task. The children used their non-preferred left foot more often during the simple task and when the object was presented to the left. Our findings also revealed interactions between gender, age, and spatial location. At five, girls used globally less their left foot than boys. In addition, girls used their preferred right foot more frequently than boys when the object was presented to the left. Based on these results, it can be concluded that foot selection depends on foot preference, task demand, environmental context, and biological factors associated with motor dominance.
本研究的目的是比较在三个空间位置执行两个不同复杂程度任务时，不同程度足偏好的右利足儿童对足的选择。30 名右利足儿童接受了测试。结果表明，根据物体的位置和任务的复杂程度，用惯用脚与物体互动的一般趋势或多或少是明显的。在简单任务和物体出现在左侧时，儿童更频繁地使用非惯用的左脚。我们的发现还揭示了性别、年龄和空间位置之间的相互作用。在五岁时，女孩使用左脚的次数普遍少于男孩。此外，当物体出现在左侧时，女孩比男孩更频繁地使用惯用的右脚。基于这些结果，可以得出结论，足的选择取决于足偏好、任务需求、环境背景以及与运动优势相关的生物因素。
