The overall aim of the proposed research is to investigate the origins and development of complex categorical representations during the first two years of life. More specifically, we are concerned with the very beginnings of superordinate structures; the acquisition of representations for different individual basic level categories from the same superordinate categories and their "coming together" to form the rudiments of superordinate categories. The proposed research derives significance from the fact that conceptual development -- the acquisition of categorical representations -- underlies mature cognitive functioning from problem solving to the abstraction of meaning from words, sentences and connected discourse. To know the developmental course of this most basic process cannot but help provide insights into understanding deviations from the normal course of cognitive development. Specific experiments are planned to determine the age at which individuated representations can be formed for basic level categories from the same superordinate structure, when these representations begin to cohere to form more global representations, whether individual representations precede more global, undifferentiated categorical representations, and whether methodological factors such as the response measure (preferential looking times following familiarization versus sequential touching) underlie apparent differences to date on the time course for the development of separate representations for basic level categories from the same superordinate category. Studies are also planned to inform us of characteristics that may enhance the formation of these basic level categories, for example, the presentation of exemplars from two as opposed to one basic level category during familiarization and the amount and nature of the familiarization experience. Finally, investigations of various familiarizing experiences on the formation of global categories are planned.

拟议研究的总体目的是研究起源 并在第一次开发复杂的分类表示 两年的生命。 更具体地说，我们关心的是 上级结构的开始；收购 来自不同单个基本级别类别的表示 相同的上级类别及其“聚在一起”以形成 上级类别的基础。 拟议的研究得出 从概念发展 - 收购的事实中的意义 分类表示 - 基础成熟的认知功能 从解决问题到从单词中的含义的抽象，句子 和连接的话语。 最了解这一发展的过程 基本过程不得不帮助提供理解的见解 偏离正常认知发展过程的偏差。 计划进行具体实验以确定年龄 可以为基本级别类别形成个性化表示 从相同的上级结构开始时，这些表示开始 是否可以形成更多的全球表示形式 在更全球，未分化的分类之前 表示，以及诸如响应之类的方法论因素是否 测量（熟悉与熟悉与 顺序接触）迄今为止的明显差异是 开发基本级别的单独表示形式的课程 来自同一上级类别的类别。 研究也是 计划向我们告知可能增强构成的特征 在这些基本级别类别中，例如 在两个基本水平类别中的示例 熟悉以及熟悉的数量和性质 经验。 最后，对各种熟悉经历的调查 计划全球类别的形成。
