This commentary makes the argument that the child-internal and child-external sources of individual differences in bilingual development are much the same as the sources of individual differences in monolingual development. It makes the further argument that the operation of the child-external influences results in differences between monolingual and bilingual development in the rate and sometimes in the outcome of language acquisition. An argument is made for the scientific and practical value of understanding the differences between monolingual and bilingual development, and future directions for research are suggested.
本评论认为，双语发展中个体差异的儿童内部和儿童外部来源与单语发展中个体差异的来源非常相似。它进一步认为，儿童外部影响的作用导致了语言习得速度和结果在单语和双语发展之间的差异。本文还论证了理解单语和双语发展之间差异的科学和实践价值，并为未来的研究提出了方向。
