ABSTRACT

Recent findings showed that children, like adults, exhibit directional biases leading to asymmetrical drawings. This appears to be the result of a complex interaction between several biological, motoric, and cultural factors. We created a drawing task designed to investigate the influence of laterality (i.e., hemispherical functional specialization and handedness) and sex on children’s graphical asymmetries. This task consists of transcribing a symmetrical three-dimensional landscape model to a two-dimensional representation. Sixty-six French pre-school children, aged between 5 and 6 years, were asked to undertake the 3D-2D transcription task, as well as the classical Alter’s directionality task. The novel task exhibited higher sensitivity than the Alter’s directionality test when examining the spatial biases resulting from handedness, and sex. Specific drawing patterns related to these variables were identified. These results suggest that, in addition to the influence of biomechanical factors and handedness, sex plays a role in children’s early graphomotor development. They also support the influence of laterality as a key factor underlying early directional biases.

摘要

最近的研究结果表明，儿童和成人一样，表现出方向偏差，导致不对称的绘画。这似乎是多种生物、运动和文化因素之间复杂相互作用的结果。我们创建了一个绘图任务，旨在研究偏侧性（即半球功能专业化和惯用手）和性别对儿童图形不对称的影响。此任务包括将对称的三维景观模型转录为二维表示。66 名年龄在 5 至 6 岁之间的法国学龄前儿童被要求承担 3D-2D 转录任务，以及经典的 Alter 方向性任务。在检查由惯用手和性别导致的空间偏差时，新任务表现出比 Alter 的方向性测试更高的灵敏度。确定了与这些变量相关的特定绘图模式。这些结果表明，除了生物力学因素和惯用手的影响外，性别在儿童早期的书写运动发展中也发挥着作用。他们还支持侧向性的影响是早期方向性偏差的关键因素。
