Representations of Abstract Quantities

量化世界的能力对于最基本的学习至关重要。认知系统负责 这种能力，即模拟量1，在许多临床人群中表现为选择性受损（例如， PD和计算障碍），使对这个系统的理解成为临床心理学的中心问题。虽然 尽管非人类动物和人类婴儿都能辨别数量，但仍有许多东西需要学习 他们的能力的性质和范围。通过对人类婴儿和 大鼠使用新的范式，我们计划检查的精度，模态独立性，和有序的性质， 这些代表。问一些问题，比如：不会说话的婴儿和非人类动物一样吗？ 表示时间、数字和大小的大小系统？这些幅度是否依赖于刺激 (and（见图）？这些非语言人群中的数量歧视是否基于 一个值大于另一个值的固有知识？在讨论这些问题时，我希望提供一个 更好地理解这些非语言的数量表示，从而导致早期的发展， 临床行为筛查

The ability to quantify the world is essential for the most basic learning. The cognitive system responsible for this ability, the analog magnitude one, appears selectively impaired in a number of clinical populations (e.g., PD and Dyscalculia), making an understanding of this system a central issue in clinical psychology. Although both non-human animals and human infants are able to discriminate quantities, there is still much to learned about the nature and extent of their competence. Through comparative investigations of human infants and rats using novel paradigms, we plan to examine the precision, modality-independence, and ordinal nature of these representations. Asking questions such as: Do preverbal infants share with non-human animals this magnitude system for representations of time, number, and size? Are these magnitudes stimulus-dependent (and thus perceptually-bound)? Are quantity discriminations in these nonverbal populations based upon inherent knowledge that one value is greater than the other? In addressing such issues, I hope to provide a greater understanding of these nonverbal quantity representations, thus leading to the development of earlier clinical behavioral screens.
