Imitative production of regular past tense -ed by English-speaking children with specific language impairment.

Background: Language intervention procedures often involve the speech-language pathologist highlighting or making more salient forms that are problematic for the child with a language impairment. According to limited processing accounts of specific language impairment (SLI), one way to increase the saliency of a form is to manipulate its sentence position.

Aims: The placement of verbs with past tense regular -ed, a morpheme documented to be significantly difficult to acquire for English-speaking children with SLI, was manipulated.
