The goal of the proposed studies is to investigate the link between posture and action in the acquisition of physical knowledge. Evidence from looking paradigms suggests that between 6 and 7 months infants begin to elaborate their conceptual knowledge about certain physical phenomena. Research on reaching has shown that the onset of postural abilities such as self-sitting (at approximately 6 months of age) expands infants' functional actions allowing access to new sources of information. A goal of the proposed research is to determine whether the onset of self-sitting is linked to the elaboration of conceptual knowledge. The studies will investigate whether the level of infant's postural ability (nonsitter, near-sitter, and sitter) is predictive of their behavior in a looking time experiment measuring conceptual relaxation. In addition, we will test whether there is a link between specific object manipulations and attaining elaborated conceptual knowledge. Finally, we will do a longitudinal study on whether infants can be taught to elaborate their concepts about physical events. The broad ranging objectives of this research have implications for gaining a better understanding how knowledge can be revealed in different experimental paradigms. The research bears on the issue of causal mechanisms in acquisition of physical knowledge and not treating age as an independent variable. There are also health related applications of this word For example, a better understanding of posture and action could lead to new therapies for sensorimotor handicaps. This research also bears on current issues in Down's syndrome research. It has been reported that infants with Down's syndrome often lack the urge to explore which could support the possible conclusion that exploratory activities have important cognitive consequences.

拟议研究的目的是调查之间的联系 获取物理知识的姿势和动作。证据 从观察范例来看，6 至 7 个月大的婴儿 开始阐述他们关于某些物理的概念知识 现象。对到达的研究表明，姿势的开始 诸如自坐等能力（大约 6 个月大时） 扩展婴儿的功能活动，允许接触新的来源 信息。拟议研究的一个目标是确定是否 自坐的发生与概念的阐述有关 知识。这些研究将调查婴儿的水平是否 姿势能力（不坐、近坐和坐）可预测 他们在观察时间实验中的行为测量概念 松弛。另外，我们会测试一下两者之间是否存在联系。 特定对象的操作和获得详细的概念 知识。最后，我们将针对婴儿是否 可以被教导阐述他们关于物理事件的概念。这 这项研究的广泛目标对获得 更好地理解如何以不同的方式揭示知识 实验范式。该研究涉及因果关系问题 获取物理知识的机制，而不是将年龄视为 一个自变量。还有与健康相关的应用 这个词例如，更好地理解姿势和动作 可能会导致感觉运动障碍的新疗法。这项研究 也与唐氏综合症研究的当前问题有关。它一直 据报道，患有唐氏综合症的婴儿通常缺乏 探索哪些可以支持探索性的可能结论 活动具有重要的认知后果。
