The temporal reliability of Brown's MLU-M was investigated with 30 normally developing children, 10 in each of three age groups: 3:6-4:6, 5:6-6:6, and 8:6-9:6 years. All children obtained MLU-Ms greater than 4.0, which placed them beyond Brown's Stage V of language learning. Language samples were evoked from these subjects on each of three consecutive days using picture stimuli. The reliability estimates indicated lack of stability for individual and average MLU-M values.
对30名正常发育儿童的布朗平均语句长度-形态（Brown's MLU-M）的时间可靠性进行了研究，这30名儿童分为三个年龄组，每组10人：3岁6个月至4岁6个月、5岁6个月至6岁6个月、8岁6个月至9岁6个月。所有儿童的平均语句长度-形态均大于4.0，这使他们超出了布朗语言学习的第五阶段。连续三天每天使用图片刺激从这些受试者身上引出语言样本。可靠性估计表明个体和平均语句长度-形态值缺乏稳定性。
