两个实验研究了新兴的坐姿能力和对称性的敏感性之间的关系，作为一个线索，以图形-背景（FG）分配在6.5个月大的婴儿（N = 80）。在每个实验中，婴儿谁可以坐在无人协助（如实验1中的父母的报告和实验2中的实验室评估）表现出敏感性的对称性作为线索FG分配，而非坐的婴儿没有。实验2进一步表明，敏感性，这种线索是不相关的一般认知能力的索引使用非相关的视觉习惯化任务。结果表明，运动发育和视觉感知之间的重要关系，并进一步表明，实现重要的运动里程碑，如稳定的坐姿可能与单眼深度分配线索，如对称性的敏感性的质的变化。
Two experiments examined the relationship between emerging sitting ability and sensitivity to symmetry as a cue to figure-ground (FG) assignment in 6.5-month-old infants (N = 80). In each experiment, infants who could sit unassisted (as indicated by parental report in Experiment 1 and by an in-lab assessment in Experiment 2) exhibited sensitivity to symmetry as a cue to FG assignment, whereas non-sitting infants did not. Experiment 2 further revealed that sensitivity to this cue is not related to general cognitive abilities as indexed using a non-related visual habituation task. Results demonstrate an important relationship between motor development and visual perception and further suggest that the achievement of important motor milestones such as stable sitting may be related to qualitative changes in sensitivity to monocular depth assignment cues such as symmetry.
