工作记忆容量的增加通常被认为是对儿童发展的主要影响，但工作记忆容量很难独立于长期知识进行检查。儿童的非词重复（NWR）性能的计算模型，独立操纵长期的知识和WM能力，以确定每个在解释发展数据的相对贡献。模拟结果表明，（a）这两种机制独立地导致相同的整体发展变化的NWR性能，（B）增加长期的知识提供了更好的拟合的儿童数据，（c）改变长期的知识和WM能力增加了没有显着的收益超过改变长期的知识。鉴于长期知识的增加必须发生在发展过程中，结果表明，WM能力的增加可能不需要解释发展差异。只有当有明确的经验理由时，工作记忆能力的提高才能被认为是发展变化的一种机制。
Increasing working memory (WM) capacity is often cited as a major influence on children's development and yet WM capacity is difficult to examine independently of long-term knowledge. A computational model of children's nonword repetition (NWR) performance is presented that independently manipulates long-term knowledge and WM capacity to determine the relative contributions of each in explaining the developmental data. The simulations show that (a) both mechanisms independently cause the same overall developmental changes in NWR performance, (b) increase in long-term knowledge provides the better fit to the child data, and (c) varying both long-term knowledge and WM capacity adds no significant gains over varying long-term knowledge alone. Given that increases in long-term knowledge must occur during development, the results indicate that increases in WM capacity may not be required to explain developmental differences. An increase in WM capacity should only be cited as a mechanism of developmental change when there are clear empirical reasons for doing so.
