When drawing faces, people show a systematic bias of placing the eyes higher up the head than they are placed in reality. This study investigated the development of this phenomenon while removing the potential confound of drawing ability. Participants (N = 124) in three age groups (3–5 yo, 10–11 yo, and adults) reconstructed two foam faces: one from observation and one from memory. The high eye placement bias was remarkably robust with mean eye placement in every condition significantly higher than the original faces. The same bias was not shown for mouth placement. Eye placement was highest for the youngest participants and for the memory conditions. The results suggest that an eye placement bias is not caused by the motor skill demands required for drawing and lend evidence to the suggestion that an eye placement bias is caused by perceptual and decision-making processes.

绘制面孔时，人们表现出系统的偏见，即将眼睛的头部抬高，而不是现实中的眼睛。这项研究调查了这种现象的发展，同时消除了潜在的绘画能力混淆。参加人数 = 124）在三个年龄段（3-5岁，10-11岁和成人）中重建了两个泡沫表面：一个来自观察，另一个来自记忆。较高的眼睛放置偏见非常显着，在每种情况下的平均眼睛放置都显着高于原始面孔。嘴部放置没有显示相同的偏差。对于最年轻的参与者和记忆条件，眼部位置最高。结果表明，眼位偏倚不是由绘画所需的运动技能要求引起的，并且有证据表明眼位偏倚是由感知和决策过程引起的。
