This study examines whether children with specific language impairment (SLI) acquiring a language with a rich case marking system (Hungarian) have difficulty with case, and, if so, whether the difficulty is comparable for spatial and nonspatial meanings. Data were drawn from narrative samples and from a sentence repetition task. Suffixes were…

The aim of this study was to determine whether children with specific language impairment (SLI) are sensitive to completion cues in their comprehension of tense. In two experiments, children with SLI (ages 4 ; 1 to 6 ; 4) and typically developing (TD) children (ages 3 ; 5 to 6 ; 5) participated in a sentence-to-scene matching task adapted from…

Purpose: Hungarian is a null-subject language with both agglutinating and fusional elements in its verb inflection system, and agreement between the verb and object as well as between the verb and subject. These characteristics make this language a good test case for alternative accounts of the grammatical deficits of children with language…

The aim of this study was to uncover factors accounting for the ability of children with specific language impairment (SLI) to learn agreement morphemes in intervention. Twenty-five children with SLI who participated in a six-month intervention program focused on teaching third person singular -s or auxiliary "is"/"are"/"was" showed a wide range…

Purpose: The goals of this investigation were to determine whether treatment assists children with specific language impairment (SLI) in the use of grammatical morphemes that mark tense and agreement and whether treatment gains influence the children's use of other, untreated morphemes. Method: Twenty-five children with SLI participated in 96…

Purpose: Many typically developing children first use inflections such as "-ed" with verb predicates whose meanings are compatible with the functions of the inflection (e.g., using "-ed" when describing events of brief duration with clear end points, such as "dropped"). This tendency is assumed to be beneficial for…

Purpose: Children with specific language impairment (SLI) often fail to produce past tense forms in obligatory contexts, although the factors affecting such inconsistency are not well understood. This study examined the influence of accompanying temporal adverbials (e.g., "just, already") on the past tense production of these children. Method:…

Sixteen-year-olds with specific language impairment (SLI), nonspecific language impairment (NLI), and those showing typical language development (TD) responded to target words in sentences that were either grammatical or contained a grammatical error immediately before the target word. The TD participants showed the expected slower response times…

Children with specific language impairment (SLI) often have extraordinary difficulty in the use of tense and agreement morphemes. Because spontaneous speech samples may not provide a sufficient number of obligatory contexts for these morphemes, structured probe items are often employed. However, these usually emphasize actions that can be readily…

A group of preschool-aged children with specific language impairment (SLI), a group of typically developing children matched for age (TD-A), and a group of younger typically developing children matched for mean length of utterance (TD-MLU) were presented with novel verbs in contexts that required them to inflect with past tense "-ed."…

Purpose: This study reports the findings of an investigation designed to examine the effects of acoustic enhancement on the processing of low-phonetic-substance inflections (e.g., 3rd-person singular "-s," possessive "-s") versus a high-phonetic-substance inflection (e.g., present progressive "-ing") by children with specific language impairment…

This paper reports on two studies of finite verb use to determine whether children with specific language impairments, who use grammatical morphemes less than typical children matched for mean length of utterance (MLU), produce other language details more frequently. The paper concluded that offsetting effects are not necessary in principle, given…

Evaluation of the speech perception of eight children (ages four and five) with specific language impairments and documented morphological difficulties found these children to be especially weak in discriminating speech stimuli whose contrastive portions had shorter durations than the noncontrastive portions (typical of English grammatical…

Children with specific language impairment (SLI) have well-documented problems in the use of tense-related grammatical morphemes. However, in English, tense often overlaps with aspect and modality. In this study, 15 children with SLI (mean age 5;2) and two groups of 15 typically developing children (mean ages 3;6 and 5;3) were compared in terms of…

This investigation examined the possibility that features necessary for morphology, such as person and number, are absent from the underlying grammars of specifically language-impaired children. (46 references) (JL)
