DESCRIPTION (provided by applicant): Pattern perception and organization provide the representations that form the basic processing units in the visual cognition system of adults. The overall aim of the proposed research is to investigate the origins and development of such perceptual organization abilities in infants. Specifically, we are concerned with the very beginnings of perceptual unit formation and the operation of a variety of organizational principles during the first months of life. The research proposal describes a number of experiments that rely on visual preference procedures to study the organization of arrays of visual elements by young infants. The experiments seek to determine: (1) Which grouping principles lead to organized representations of visual pattern information? (2) Do some principles consistently take precedence over others, thereby suggesting a hierarchy of rule use in the development of perceptual organization? (3) Can the principles work in an additive fashion, thus suggesting a kind of threshold model for perceptual unit formation? (4) What is the time course of development for each of the various principles? Are the individual principles yoked or do they have independent developmental trajectories? And (5) What are the developmental factors (i.e., maturation, experience) that affect the emergence of the different grouping principles? The significance of the proposed research is that it will provide knowledge about how perceptual units are formed, their nature, and their ontogenesis as well as how representations of visual pattern information by adults arise from the perceptual units of infants. In short, this research will inform us about the formation of the coherent representations of visual patterns that form the basic functional units of human cognition. Knowledge about the development of this fundamental mental ability will also provide insights into understanding deviations from the normal course of perceptual-cognitive development.

描述（由申请人提供）：模式感知和组织提供了形成成人视觉认知系统基本处理单元的表示形式。拟议研究的总体目的是调查婴儿感知组织能力的起源和发展。具体而言，我们关注的是，在生命的头几个月中，感知单位形成和各种组织原则的运作的开始。研究建议描述了许多依赖视觉偏好程序来研究年轻婴儿视觉元素阵列的实验。实验试图确定：（1）哪些分组原理导致有组织的视觉模式信息表示？ （2）一些原则是否始终优先于其他原则，从而暗示了在感知组织的发展中使用规则的层次结构？ （3）原理可以以添加的方式工作，从而提出一种感知单位形成的阈值模型？ （4）各种原则的发展时间过程是什么？是个人原则是否受到训练，还是它们具有独立的发展轨迹？ （5）影响不同分组原则出现的发展因素（即成熟，经验）是什么？拟议的研究的意义在于，它将提供有关感知单位的形成，其性质和个体发生以及成人视觉模式信息的表示的知识。简而言之，这项研究将告知我们形成构成人类认知基本功能单位的视觉模式的连贯表示。关于这种基本心理能力发展的知识还将为理解与知觉认知发展的正常过程的偏差提供见解。
