A critical clinical issue is the identification of a clinical marker, a linguistic form or principle that can be shown to be characteristic of children with Specific Language Impairment (SLI). In this paper we evaluate, as candidate clinical markers, a set of morphemes that mark Tense. In English, this includes -s third person singular, -ed regular past,(More)
English-speaking children with specific language impairment (SLI) are known to have particular difficulty with the acquisition of grammatical morphemes that carry tense and agreement features, such as the past tense -ed and third-person singular present -s. In this study, an Extended Optional Infinitive (EOI) account of SLI is evaluated. In this account,(More)
Tense marking in English is relatively late appearing and is especially late for children with Specific Language Impairment (SLI). Little is known about the full course of acquisition for this set of morphemes. Because tense marking is a fundamental property of clause construction, it is central to current theories of morphosyntax and language acquisition.(More)
Children with specific language impairment (SLI) are known to have limited lexicons. Previous studies implicate a possible processing problem, in the form of a limited ability to comprehend new words in settings that require Quick Incidental Learning (QUIL). This study investigates further the factors contributing to limited QUIL by examining the effects of(More)
PURPOSE The primary objectives of this study were to determine the prevalence of late language emergence (LLE) and to investigate the predictive status of maternal, family, and child variables. METHOD This is a prospective cohort study of 1,766 epidemiologically ascertained 24-month-old singleton children. The framework was an ecological model of child(More)
Two models of the relationship between socioemotional behavior and verbal abilities are compared: Social Adaptation and Social Deviance. The socioemotional integrity of 17 children with specific language impairment (SLI) and 20 unaffected children who were age-matched (AM) was examined using the Child Behavior Checklist (CBCL) and the Teacher's Report Form(More)
We analyzed genetic linkage and association of measures of language, speech and reading phenotypes to candidate regions in a single set of families ascertained for SLI. Sib-pair and family-based analyses were carried out for candidate gene loci for Reading Disability (RD) on chromosomes 1p36, 3p12-q13, 6p22, and 15q21, and the speech-language candidate(More)
This study reports on the outcomes of an investigation designed to evaluate competing accounts of the nature of the grammatical limitations of children with specific language impairment (SLI) with a new comprehension measure involving well-formedness judgments. It is a follow-up to the longitudinal study of Rice, Wexler, and Hershberger (1998), which(More)
A plural elicitation task and a nominal compounding task were administered to a group of children with SLI and two groups of normally developing children, an age-equivalent group (CA) and a language-equivalent group (MLU). Across tasks, differences between the CA and SLI groups were significant, but differences between the MLU and SLI groups were not. These(More)
PURPOSE The mean length of children's utterances is a valuable estimate of their early language acquisition. The available normative data lack documentation of language and nonverbal intelligence levels of the samples. This study reports age-referenced mean length of utterance (MLU) data from children with specific language impairment (SLI) and children(More)
