作者研究了幼儿绘画变异性是否最好通过以下因素来解释：（a）对明确计时系统的要求，（b）控制肢体动态的能力不发达，或（c）两者兼而有之。与不连续任务相比，连续绘图的显式计时要求较低。作者通过改变所涉及的关节数量来操纵肢体动力学，画线所需的关节比画圆所需的关节少。结果表明，幼儿在不连续转圈时具有较高的时间变异性，但在其他条件下则不然。作者认为，肢体控制的明确时间安排和动态复杂性可能是时间一致性的决定因素，因此可能在儿童绘画和写作技能的发展中发挥重要作用。
The authors studied whether the drawing variability in young children is best explicable by (a) demands on the explicit timing system, (b) an underdeveloped ability to control limb dynamics, or (c) both. The explicit timing demands were lower in continuous drawing in comparison with the discontinuous task. The authors manipulated limb dynamics by changing the number of joints involved, with line drawing requiring fewer joints than circle drawing. Results showed that young children had high temporal variability in discontinuous circling but not in other conditions. The authors argue that both explicit timing and dynamic complexity of limb control may be determinants of temporal consistency and may thus play an important role in the development of drawing and writing skills in children.
