The broad goal of this proposal is to gain a deeper understanding of the adult human mathematical mind by studying its development in infancy. A major goal is to test the hypothesis that infants rely on analog magnitude representations of number similar to those used by adults, young children, and non-human animals. Previous studies suggest that infants may rely on two distinct systems for representing number; an object-file system for representing small values and an analog magnitude mechanism for representing large numerical values. This hypothesis will be tested by studying the psychophysics of number discrimination over a wide range of numerical values, testing whether infants are sensitive to ordinal relations between numerosities, and taking the first step to determine whether the enumeration process(es) that infants use involves serial or parallel processing. The proposed experiments will use the time that infants look at various displays and the location of infants. eye movements as dependent measures. The results of the proposed studies should provide a strong foundation for the development of a coherent model of the development of non-verbal numerical representations and will contribute to the principal investigator.s long-term goal of studying both the evolution and the development of numerical cognition.

这项提议的总体目标是通过研究婴儿期人类数学思维的发展，对成人数学思维有更深入的了解。一个主要的目标是测试婴儿依赖于类似于成人、幼儿和非人类动物使用的数字的模拟数量级表示的假设。先前的研究表明，婴儿可能依赖于两种不同的系统来表示数字；表示小数值的对象文件系统和表示大数值的模拟幅度机制。这一假设将通过研究广泛数值范围内的数字辨别的心理物理学，测试婴儿是否对数字之间的序数关系敏感，并采取第一步来确定婴儿使用的枚举过程是否涉及串行或并行处理来验证。该实验将利用婴儿观看各种显示器的时间和婴儿的位置。眼动作为依赖的测量。建议的研究结果应该为非语言数字表征发展的连贯模型的发展提供坚实的基础，并将为首席研究员做出贡献。我们的长期目标是研究数值认知的演变和发展。
