Object individuation, the capacity to track the identity of objects when perceptual contact is lost and then regained, is fundamental to human cognition. A great deal of research using the violation-of-expectation method has been conducted to investigate the development of object individuation in infancy. At the same time, there is a growing need for converging methods of study. Reported here are data obtained with from a newly developed search task that can be used with infants as young as 5 months of age. The results suggest that this method is a sensitive measure of object individuation in young infants and demonstrate the advantages of using converging methods of study.
客体辨别,即在感知接触丧失后重新获得时追踪客体身份的能力,是人类认知的基础。使用违反预期的方法进行了大量研究,以调查婴儿期客体辨别的发展。同时,越来越需要汇聚的研究方法。本文报告了使用新开发的搜索任务获得的数据,该任务可用于年龄在 5 个月以下的婴儿。结果表明,该方法是一种测量幼儿客体辨别的敏感指标,并证明了使用汇聚研究方法的优势。
