作者分析了104个语言样本，从42个不同的正常语言学习儿童在25，29和35个月的年龄，为11个语法语素的比例使用：复数-s。所有格的。进行式、规则和不规则的过去式、规则和不规则的现在式，以及系动词和助动词to be的可缩形式和不可缩形式。广泛的变异性被发现在样本中的比例使用每个语素，无论是按年龄或平均话语长度（MLU）的样本进行分组。在25个月和29个月时，11个语素中有9个的使用比例超过0.95，而在35个月时，有8个的使用比例超过0.50。在MLU水平为2.50-2.99时，8个语素的得分范围为0.90或更大，其余3个超过0.65。当MLU为4.00或更高时，范围缩小了，但仍有4个语素的MLU为0.50或更高。按MLU水平获得的排名顺序与文献中先前报道的略有不同（例如，与其他研究报告的结果相比，收缩系动词的排名较高，不规则过去的排名较低）。MLU和吗啡使用的相关性在0.11到0.74之间。只有3个词素的rho > 0.60，4个词素的rho <0.35。这些数据与文献中报道的具体语言障碍（SLI）儿童的比较表明，组的平均值一般较低的SLI儿童，但许多SLI儿童的分数重叠的儿童在这里研究。
The authors analyzed 104 language samples, obtained from 42 different normal language learning children at 25, 29, and 35 months of age, for the proportional use of 11 grammatical morphemes: plural -s. possessive 's. progressive -ing, regular and irregular past, and regular and irregular present, as well as the contractible and uncontractible forms of the copula and auxiliary to be. Wide variability was found among the samples in the proportional use of each morpheme, whether the samples were grouped by age or mean length of utterance (MLU). At ages 25 and 29 months, the range of proportional use was over .95 for 9 of the 11 morphemes, and at 35 months, it was .50 or greater for 8. At an MLU level of 2.50-2.99, the range of scores was .90 or greater for 8 of the morphemes, and over .65 for the remaining 3. By MLUs of 4.00 or more, ranges had narrowed but were still .50 or greater for 4 of the morphemes. Rank order of acquisition by MLU level varied somewhat from that previously reported in the literature (e.g., contractible copula was ranked higher and irregular past was ranked lower than has been reported in other studies). Correlations of MLU and morphane use ranged from .11 to .74. with rho > .60 for only 3 and < .35 for 4 morphemes. Comparisons of these data with those reported in the literature on specifically language-impaired (SLI) children indicated that group means were generally lower for SLI children, but that many of the SLI children's scores overlapped with those of the children studied here.
