A growing body of research indicates connections exist between action, perception, and cognition in infants. In this study, associated changes between sitting ability and upright face processing were tested in 111 infants. Using the visual habituation "switch" task (C. H. Cashon & L. B. Cohen, 2004; L. B. Cohen & C. H. Cashon, 2001), holistic processing of faces was assessed in same-aged non- and near sitters (22-25 weeks) and same-aged new and expert sitters (27-32 weeks). U-shaped relation was found between sitting stage and holistic face processing such that only nonsitters and expert sitters processed faces holistically. It is posited that the results are due to a reorganization of the upright face-processing system resulting from infants' learning to sit independently and trying to incorporate the meaning of upright faces.
越来越多的研究表明,婴儿的动作、知觉和认知之间存在联系。在这项研究中,研究人员测试了 111 名婴儿的坐姿能力和直立面孔处理之间的关联变化。研究人员使用视觉习惯化“切换”任务(C. H. Cashon & L. B. Cohen,2004;L. B. Cohen & C. H. Cashon,2001),评估了同龄非坐姿婴儿和接近坐姿婴儿(22-25 周)以及同龄新坐姿婴儿和熟练坐姿婴儿(27-32 周)对面孔的整体处理能力。研究发现,坐姿阶段和整体面孔处理之间存在 U 型关系,只有非坐姿婴儿和熟练坐姿婴儿对面孔进行整体处理。研究人员认为,这一结果是由于婴儿独立学习坐姿和尝试理解直立面孔的意义,导致了直立面孔处理系统的重新组织。
