在一项对18名儿童的纵向研究中，研究了从缓慢到快速单词学习的过渡。从1岁开始;2，母亲们把孩子的话记在日记里。每两周半打电话给家里讨论日记条目。从日记记录中按时间顺序记录了名词和其他词类，13名儿童证明了长达3个月的时间，在此期间，习得率显着增加。在这一时期学习的词汇中，几乎有四分之三是名词。五个孩子表现出更渐进的单词学习，并获得了平衡的名词和其他词类。这些结果表明，“词汇量激增”和“命名爆炸”最好地描述了那些将早期语言努力集中在一个策略上的孩子：学习事物的名称。其他孩子可能会尝试用更多样的词汇来编码广泛的经验，这是一种导致词汇逐渐增长的策略。
The transition from slow to rapid word-learning was examined in a longitudinal study of 18 children. Beginning at age 1;2, mothers kept a diary of children's words. Diary entries were discussed during phone calls to the home every 2½ weeks. A chronological record of nouns and other word classes was coded from the diary records.Thirteen children evidenced a prolonged period of up to three months during which rate of acquisition markedly increased. Almost threequarters of the words learned during this period were nouns. Five children evidenced more gradual word-learning, and acquired a balance of nouns and other word classes. These results suggest that the terms ‘vocabulary spurt’ and ‘naming explosion’ best describe children who focus their early linguistic efforts on a single strategy: learning names for things. Other children may attempt to encode a broad range of experience with a more varied lexicon, a strategy that results in more gradual lexical growth.
