Novel Words

This investigation examined the influence of unsolicited lexical imitation on the comprehension and on the production of novel words by language-impaired children. Subjects were 13 children (2:8–3:1) exhibiting specific language impairment who were presented with 16 unfamiliar words referring to unfamiliar objects or actions over 10 experimental sessions. Unsolicited imitations appeared to facilitate subsequent production of these words on a posttest. This effect was greatest when these words were also produced spontaneously prior to the posttest. Words that were produced imitatively and spontaneously also appeared more frequently in spontaneous usage than words that were only produced spontaneously. No relationship between such imitations and comprehension was observed. These findings suggest that unsolicited imitations benefit children's lexical acquisition primarily by providing them with additional opportunities to produce words that are in the process of being established in their expressive lexicons.

It was hypothesized that the initial word comprehension of specific-language-impaired children would be enhanced by the insertion of a short pause just before a sentence-final novel word. Three groups of children served as subjects: twenty 5-year-old, specific-languageimpaired (SLI) children, and two comparison groups of normally developing children, 20 matched for mean length of utterance (MLU) and 32 matched for chronological age (CA). The children were randomly assigned to two conditions for viewing video programs. The programs were animated stories that featured five novel object words and five novel attribute words, presented in a voice-over narration. The experimental version introduced a pause before the targeted words; the control version was identical except for normal prosody instead of a pause. Counter to the predictions, there was no effect for condition. Insertion of a pause did not improve the SLI children’s initial comprehension of novel words. There were group main effects, with the CA matches better than either of the other two groups and no differences between the SLI children and the MLU-matched children.

A group of specifically language-impaired (SLI) children was compared with a matched group of non-SLI children (i.e., children displaying normal language) on tests of speech perception and language ability. The tests were administered longitudinally at times separated by an interval of 4 years. Initially (i.e., Time 1), the groups differed significantly in discrimination, sequencing, and rate processing of and serial memory for synthesized /ba/ and /da/ stimuli. At Time 1, age effects were also observed among both groups of children. That is, performance improved as a function of increased age. At follow-up (i.e., Time 2), performance was at or near ceiling for subjects in both groups, indicating that perceptual development occurred in both groups of children. Results are discussed in relation to the hypothesis that perceptual deficits play a causal role in specific language impairment.

Conversational replies were examined in two groups of children with comparable vocabularies and speech limited to single-word utterances: children with specific language impairment, ages 2:10 to 3:6 (years:months); and children, ages 1:5 to 1:11, who were developing language normally. In interactions with adults the language-impaired children produced a greater number and variety of replies to both questions and statements than the normal-language children. The findings suggest that language-impaired children can serve as responsive conversationalists when syntactic skill is not a factor and that comprehension, world knowledge, and/or experience with conversations permit considerable variability in conversational skill even within the same level of expressive language ability.

This paper views specific language disorders as a heterogeneous group of language-impaired children consisting of distinct subtypes, each potentially accounted for by differing causal factors. Identifying causal factors for subgroups of children with specific language impairment is important (a) to extend our discipline beyond the descriptive stage of science, (b) to address questions motivating referrals from parents and professionals, (c) to plan intervention programs, and to prevent specific language disorders.

Selection Of

A standard approach to the selection of children with specific language deficit was devised. The approach was based on a current definition of specific language deficit that depends heavily on exclusion criteria. Children with known language deficit who had hearing impairment, cognitive deficit, neurologic deficit, or emotional or behavioral disorder were excluded. Both the exclusion criteria and the criteria dealing with required extent of language impairment were specified in considerable detail. A total of 132 language-impaired children aged 4–8 1/2 years were assessed. Criteria for selection of a matched group of normal-language children were also specified. The language-impaired children were referred to the project by speech and language clinicians in accordance with a set of broadly defined criteria. Contrary to expectations, less than one third of the children from this group met the more precisely defined criteria employed in the project. In addition, those who were selected did not form a homogeneous group but showed considerable variation in expressive versus receptive language and in articulation skill. The selection approach and its effectiveness for the purposes of clinical research and intervention studies are discussed.
