Temporal correspondences between the attainment of specific milestones in play and language were examined through a longitudinal study of four Japanese children (aged 0;7 to 0;11 at the beginning of the study). There were developmental correspondences between the onset of six language landmarks (the emergence of first words, naming words, vocabulary spurts, word-chains, nonproductive two-word utterances, productive two-word utterances) and the onset of subcategories of play. Language and play both reflected the development of underlying symbolic ability, and both developed in parallel manner at the single-word stage. After the emergence of word-chains, language and play developed interdependently. All the children proceeded through the same sequence of stages, but the rate of development was different depending on their environment.
通过对四名日本儿童（研究开始时年龄为0；7至0；11岁）的纵向研究，考察了游戏和语言中特定里程碑达成之间的时间对应关系。六个语言标志（第一个单词的出现、命名单词、词汇激增、词链、非生成性双词话语、生成性双词话语）的出现与游戏子类别之间存在发展对应关系。语言和游戏都反映了潜在象征能力的发展，并且在单词阶段以平行方式发展。词链出现后，语言和游戏相互依存地发展。所有儿童都经历了相同的阶段顺序，但发展速度因环境而异。
