(1)成年人在句法和形态发展的早期阶段比儿童更快（在时间和接触保持不变的情况下）。(2)年龄较大的儿童比年龄较小的儿童获得更快（同样，在时间和暴露保持不变的形态和句法发展的早期阶段）。(3)在儿童时期开始自然接触第二语言的习得者通常比成年后开始接触第二语言的人获得更高的第二语言熟练度。
(1) Adults proceed through early stages of syntactic and morphological development faster than children (where time and exposure are held constant). (2) Older children acquire faster than younger children (again, in early stages of morphological and syntactic development where time and exposure are held constant). (3) Acquirers who begin natural exposure to second languages during childhood generally achieve higher second language proficiency than those beginning as adults.
