Children's productions of the affix -ed in past tense and past participle contexts (e.g., the boy kicked the ball vs. the ball was kicked) were examined in spontaneous conversations and elicited productions. The performances of 7 children with specific language impairment (SLI) were compared with those of 2 control groups of typically developing children (age matches, MLU matches). Children with SLI produced fewer obligatory contexts for both past tense and past participle forms than did the control children, and were more likely to omit past tense affixes. In contrast, few omissions of the past participle were observed across all 3 groups. Implications for theories regarding the morphological deficits associated with SLI are discussed.
在自然对话和诱发产出中，研究了儿童在过去式和过去分词语境中对词缀-ed的产出情况（例如，男孩踢了球与球被踢了）。将7名患有特定语言障碍（SLI）的儿童的表现与2个发育正常儿童对照组（年龄匹配、平均语句长度匹配）的表现进行了比较。与对照组儿童相比，患有SLI的儿童在过去式和过去分词形式上产生的必用语境较少，并且更有可能省略过去式词缀。相比之下，在所有3组中，过去分词的省略情况很少。讨论了对与SLI相关的形态学缺陷理论的影响。
