在许多儿童语言发展和障碍的研究中，一个广泛采用的做法是采用一个容易计算的数字度量，平均话语长度测量语素（MLU），作为“语法发展的一般指标”。虽然这种做法似乎已经在许多儿童语言的学生中得到了认可，但MLU在第二阶段之后的有用性一直被假定，但从未经过实证检验。本研究对18名正常发育的2 ~ 3岁儿童的语法表现和MLU进行了评估，发现MLU与年龄无显著相关（r = 0.26），也不能区分儿童的语法发展概况。
A widely held practice in many studies of child language development and disorders has been to employ an easily calculated numerical metric, mean length of utterance measured in morphemes (MLU), as a ‘general index of grammatical development’. While this practice seems to have found acceptance among many students of child language, the usefulness of MLU past Stage II has been assumed but never empirically tested. This study evaluated the grammatical performance and MLU of 18 normally developing 2- and 3-year-old children and found that MLU did not correlate significantly with age (r = 0·26), nor did it discriminate children's profiles of grammatical development.
