This fellowship would support collaborative research with Stanislas Denaene on the nature and development of number representations in human infants, young children, and human adults. Adults' number representations will be assessed using both behavioral and neuroimaging techniques (fMRI, ERPs) to test the hypothesis that mature representations of number depend on two distinct subsystems: an exact small-number system and an approximate large-number system, that are coordinated by natural language. Children's number representations will be assessed using behavioral and neuroimaging techniques (ERPs) to test the hypothesis that children assemble the same two systems in learning number words and verbal counting. Finally, infants' number representations will be assessed using behavioral and neuroimaging techniques (ERPs and optical imaging) in an initial effort to chart the developmental origins of these two systems. The research will be conducted. during two visits by Spelke to Dehaene's lab in Paris: an initial visit of 10 months (from 11/O1/00 to 8/31/01). and a follow-up visit of 2 months (from 07/01/02 torn 08/31/02)

该奖学金将支持与斯坦尼斯拉斯·丹奈（Stanislas Denaene）的合作研究，涉及人类婴儿，幼儿和人类成年人的性质和发展。将使用行为和神经影像学技术（fMRI，ERP）评估成年人的数字表示，以测试以下假设：成熟数字的成熟表示取决于两个不同的子系统：一个精确的小数字系统和一个近似的大数字系统，这些系统是由自然语言协调的。将使用行为和神经影像技术（ERP）评估儿童的数字表示，以测试孩子在学习数字和口头计数中组装相同两个系统的假设。最后，将使用行为和神经影像技术（ERP和光学成像）评估婴儿的数字表示，以绘制这两个系统的发展起源。该研究将进行。在Spelke对巴黎Dehaene实验室的两次访问中：初次访问10个月（从11/O1/00到8/31/01）。以及2个月的后续访问（从07/01/02撕裂08/31/02）
