项目摘要

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.

拟议研究的目标是调查姿势和动作在获取物理知识。证据从观察范式表明，6至7个月的婴儿，开始阐述他们对某些物理的概念性知识现象。关于伸手的研究表明，姿势性动作的发生能力，如自我坐（约6个月大）扩大婴儿的功能性行动，使其能够获得新的来源，信息.拟议研究的一个目标是确定自我静坐的开始与概念的阐述有关，知识这些研究将调查婴儿的水平是否姿势能力（non-sitter，near-sitter和sitter）是预测他们的行为在一个观察时间实验测量概念放松.此外，我们将测试是否有一个链接，具体的对象操作和实现详细的概念知识最后，我们将做一个纵向研究，可以被教导来阐述他们对物理事件的概念。的这项研究的广泛目标对获得更好地理解知识如何在不同的实验范例这项研究涉及到因果关系的问题获得物理知识的机制，而不是将年龄视为独立变量。也有与健康相关的应用，例如，更好地理解姿势和动作可能会为感觉运动障碍带来新的治疗方法。本研究也关系到唐氏综合症研究中的当前问题。已经患有唐氏综合症的婴儿通常缺乏探索性研究可以支持可能的结论，活动具有重要的认知后果。
