项目摘要

My research program is concerned with how infants successfully organize the world into meaningful object categories. There is currently a hot debate about whether infants' first categories are relatively broad or relatively narrow, as well as about the conceptual nature of the categories infants form (Mandler, 2004, Quinn, 2002). One basic issue about which there is considerable controversy is the relative importance of conceptual features (features that cannot be seen) and perceptual features (what objects look like) in infants' formation of categories. This issue will be the main focus of my research program. In a series of experiments, I will examine how experience with objects and knowledge of object labels impact on the categories infants form, more specifically on developmental changes in the use of static and dynamic features (e.g., object parts) to group items. Infants aged 9 to 24 months will be administered a wide range of categorization tasks, including the object examination, sequential touching, infant-controlled habituation, and generalized imitation techniques. We will also collect data on scanning patterns of objects with eye tracking equipment adapted for infants. The effect of exposure and object labels on category formation will be examined by manipulating familiarity with objects, including exposure to video clips showing moving category exemplars and by measuring comprehension and production of object labels. Taken together, the proposed research program should shed new light on how infants establish their categories during the first two years of life.

我的研究计划关注的是婴儿如何成功地将世界组织成有意义的对象类别。目前，关于婴儿的第一类是相对较宽还是相对较窄，以及婴儿形式的概念性性质（Mandler，2004； Quinn，2002）。存在重大争议的一个基本问题是概念特征（无法看到的特征）和婴儿形成形成中的感知特征（对象看起来像什么样的特征）的相对重要性。这个问题将是我的研究计划的主要重点。在一系列实验中，我将研究对象和对象标签的知识对婴儿形式形式的影响，更具体地说是在使用静态和动态特征（例如对象部分）对组项目中使用的发展变化。 9至24个月的婴儿将受到广泛的分类任务，包括对象检查，顺序接触，婴儿控制的习惯和广义模仿技术。我们还将收集有关针对婴儿的眼睛跟踪设备的扫描模式的数据。曝光和对象标签对类别形成的影响将通过操纵对象的熟悉度来检查，包括接触视频片段，显示移动类别的示例，并测量对象标签的理解和生产。综上所述，拟议的研究计划应阐明婴儿在生命的头两年中如何建立自己的类别。
