The role of action in the development of visual object recognition

视觉物体识别过程在人类的多个方面发挥着核心作用 认知力。然而，人们对这些过程的发展知之甚少 超越婴儿期的最早阶段。一部长篇的文学作品暗示着一种深刻的 成年人的视觉和行动之间的基本协调。行动的一种方式 对视觉发展至关重要的是一个人自己对物体的动作 生成人们接收到的关于对象的动态视觉体验。自我- 生成的动作从字面上创建一个人的对象视图。在拟议的研究中，我们 寻求理解发展变化在自我产生的行动中的作用 视觉对象表示和识别的发展。参与者将是 18至24个月大的儿童，在此年龄段之前有工作 表明物体识别发生了显著的发展变化。这个年龄 在通常发育的儿童中，Range也是语言快速扩展的时期，并且 语言、运动和更广泛的认知的非典型模式的时期 发展往往是首先确定的。因此，对自生成动态视图的研究 将提供一个新的窗口来了解疾病的发生机制和早期诊断。 非典型认知发展。我们关注视觉对象表示的三个方面， 建议在成人高水平视力的研究中发挥重要作用，我们的初步研究 研究表明，在18至24个月的时间内有以下原因：1)倾向于认为原因 以及出现对查看对象平面的偏好的后果 (边、前、后、顶和底)，而不是平面之间区域的视图； 2)延伸轴儿童握力和握力发育变化的原因 相对于对象的伸长轴移动对象，以及 儿童对这些物体的感知和表征；以及3)全球结构 通过稀疏的几何结构特征识别对象的能力。 我们将使用横断面研究和培训研究来研究行动在 这些方面的每一个都典型地发展了儿童的视觉物体识别。

Processes of visual object recognition play a central role in multiple aspects of human cognition. However, very little is known about the development of these processes beyond the earliest stages of infancy. A long literature suggests a deep and fundamental coordination between vision and action in adults. One way in which action should matter critically to visual development is that one's own actions on objects generates the dynamic visual experiences that one receives about objects. Self- generated actions literally create one's views of objects. In the proposed research, we seek to understand the role of developmental changes in self-generated action in the development of visual object representations and recognition. The participants will be children between 18 and 24 months of age  an age range during which prior work indicates that significant developmental change in object recognition occurs. This age range is also a period of rapid language expansion in typically developing children, and a period in which atypical patterns of language, motor, and more diffuse cognitive development are often first identified. Thus, the study of self-generated dynamic views of object structure will provide a new window into mechanisms and early diagnosis of atypical cognitive development. We focus on 3 aspects of visual object representations, suggested to be important in studies of high level vision in adults, which our preliminary studies indicate have roots in the 18 to 24 month period: 1) Preferred views  the causes and consequences of the emergence of a preference for viewing the planes of objects (sides, front, back, top, and bottom) rather than views of areas between planar surfaces; 2) Axes of elongation  the causes of developmental changes in how children hold and move objects relative to the objects' axes of elongation, and the consequences for children's perception and representation of those objects; and 3) Global structure  the ability to recognize objects from sparse characterizations of their geometric structure. We will use both cross-sectional, and training studies to investigate the roles of action in each of these aspects of typically developing children's visual object recognition.
