项目摘要

PROJECT SUMMARY Human visual object recognition is remarkable in its ability to recognize individual objects in challenging circumstances and to rapidly recognize even novel instances of tens of thousands of everyday categories. Although a great deal is known about these processes at maturity, very little is known about their development especially with respect to common everyday objects and the experiences that support robust object recognition and categorization. This gap is critical because object recognition and categorization support early word learning, physical problem solving, and the later learning of orthographies and mathematical symbols. This research projects focuses on visual object learning in 1 year old toddlers, a developmental period that at the front end of marked advances in visual object recognition and a period in which children with multiple risk factors begin to fall behind the normative developmental trajectory. The approach focuses on the properties of real- world visual experiences that support learning to recognize individual objects in challenging visual contexts and generalizing that learning to same category members. The method uses head-mounted eye-trackers to capture field-of-view images from 100 infants 17 to 22 months of age as they spontaneously interact and play with objects. Through active interactions with objects infants generates their own packets of visual data for learning. Multiple visual properties relevant to object perception will be algorithmically measured and quantified. Toddlers’ recognition of the actively-engaged object and a novel object from the same category will be measured in challenging benchmark contexts including clutter, occlusion, and different views. Category generalization will be measured in a name generalization task. Advanced statistics and machine learning will determine the visual properties of self-generated experiences that support infants object recognition and categorization. The research will provide the first characterization of the natural visual statistics of toddlers’ active interactions with objects and potentially transformative evidence that the developmental foundation for human prowess in visual object categorization lies not in experiences with many different instances of a single category, the standard assumption, but in active visual experiences with individual objects. Moreover, infants at risk for Developmental Language Delay and Autism show disruptions in early object name learning that have been recently linked to disruptions in visual learning about objects. The project includes preliminary analyses of infants at risk in preparation for the next step in the long-term research program.

项目概要人类视觉物体识别能力非常出色，能够在具有挑战性的情况下识别单个物体并能够快速识别数以万计的日常类别中的新实例。尽管人们对这些成熟过程了解很多，但对其发展却知之甚少特别是对于常见的日常物体和支持强大的物体识别的体验这种差距至关重要，因为对象识别和分类支持早期单词。学习、物理问题解决以及后来的拼字法和数学符号的学习。研究项目侧重于 1 岁幼儿的视觉对象学习，这是一个发展时期视觉物体识别显着进步的前端，以及具有多种危险因素的儿童的时期开始落后于规范的发展轨迹。世界视觉体验，支持学习在具有挑战性的视觉环境中识别单个物体，以及该方法使用头戴式眼动仪来捕捉相同类别的成员的学习情况。 100 名 17 至 22 个月大的婴儿自发互动和玩耍时的视野图像通过与物体的积极互动，婴儿生成自己的视觉数据包以供学习。与物体感知相关的多种视觉特性将通过算法进行测量和量化。对主动参与的物体和同一类别的新物体的识别将在具有挑战性的基准环境，包括混乱、遮挡和不同的类别概括。在名称泛化任务中进行测量，高级统计和机器学习将确定视觉效果。支持婴儿物体识别和分类的自我生成体验的特性。将提供幼儿与物体主动互动的自然视觉统计的第一个特征以及潜在的变革性证据，表明人类在视觉对象方面的能力的发展基础分类不在于对单一类别的许多不同实例的经验，标准假设，但在对单个物体的主动视觉体验中，婴儿有发育风险。语言发育迟缓和自闭症表明早期物体名称学习受到干扰，最近与该项目包括对处于危险中的婴儿的初步分析。为长期研究计划的下一步做好准备。
