Similar Tendency

This study examined the characteristics of early lexical acquisition in children with specific language impairment. Sixteen unfamiliar words and referents were exposed across 10 sessions to language-impaired and normal children matched for level of linguistic development. Posttesting revealed similar comprehension-production gaps in the two groups of children. In addition, both groups showed greater comprehension and production of words referring to objects than words referring to actions. However, the language-impaired children's object word bias was not as marked as that of the normal children. For both groups, words containing initial consonants within the children's production repertoires were more likely to be acquired in production than words containing consonants absent from the children's phonologies. A similar tendency was not seen for comprehension.

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.

Unfamiliar Object

ABSTRACTSpecifically-language-impaired children and younger normal children matched for expressive language were presented with unfamiliar object names and referents across five experimental sessions. The objects differed in the degree to which they were associated with actions, and only certain of the object exemplars were named during presentation. Comprehension testing revealed that the specifically-language-impaired children acquired a greater number of object concepts presented in a no-action condition than the normal children. However, their extension of the names to new exemplars was more restricted and less differentiated. Several possible accounts of these findings are evaluated.

Many children are diagnosed as "specifically language-impaired" principally on the basis of their low scores relative to the norm on language measures. Yet it is often assumed that such children must suffer from a subtle disruption or defect in some peripheral or central mechanism that is involved in language learning. In this paper, an alternative view is offered: Many of these children may simply be limited in language ability in much the same way that others may be poor in musical, spatial, or bodily kinesthetic abilities.

Auditory Temporal Resolution

Recently there has been renewed interest in the auditory processing capabilities of children with specific language impairment. In this study, eight children with specific language impairment and eight nonimpaired, age-matched peers completed a task to assess temporal resolution abilities. Children were asked to detect a tone in three masking conditions wherein the masker contained silent gaps of 0 msec., 40 msec., or 64 msec. in duration. Thresholds were measured in each masking condition at 500 Hz and 2000 Hz. Across the groups, thresholds decreased (improved) significantly as a function of increases in the duration of the gaps. Children in the two groups exhibited remarkably similar thresholds for the three masking conditions. However, children with specific language impairment required a significantly greater number of ascending trials to achieve the threshold criterion than did age-matched children. Results suggest that language-impaired children perceive temporal aspects of acoustic stimuli as well as their normally developing peers. Attentional mechanisms may play an important role in the difficulties they exhibit in auditory processing.

A 3-year longitudinal study of the language performance of children from poverty was designed to address the problem of separating children with a specific language impairment (SLI) from low-scoring normal children in the borderline area on the continuum of language performance where normal ends and abnormal begins. Two approaches to definition were compared: an experimental approach (using story-retelling, rote-memory ability, and invented-morpheme learning) and a traditional approach (using standardized-test discrepancy scores). Results indicated that 6 of 34 children tracked from kindergarten through second grade appeared to be SLI at the end of the study. The best kindergarten predictor for the outcome status of these 6 children was a combination of the score on the Oral Vocabulary subtest of the TOLD-2P and the score on a combination of the experimental tasks. The best single kindergarten predictor of the academic status of the 15 children in the study who received academic remediation was story-retelling. Children’s scores on the experimental and standardized tests of language performance and nonverbal intelligence were profiled over the 3 years of the study, and patterns of change in many instances reveal the lifting of the early influences of poverty.

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.

AbstractThis article presents research on a learning potential assessment that was administered to 32 preschool children with typical development, and 32 with specific language impairment receiving treatment at CADIT: the Children’s Center for Early Intervention and Development. The study’s main objective was to examine whether the language-impaired group’s cognitive profile could improve by applying learning potential methodology. Its second aim was to demonstrate the effectiveness of mediation in both groups. The results revealed significant differences between the two groups at pretest on most subscales. As for the second objective, we observed differences between pretest and posttest scores in both groups. In the second group, all differences were significant except in the case of classification and auditory memory, while in the first group, the differences between pretest and posttest scores were significant on all sub-scales but visual memory.

Teachers often use analogies in classroom settings to clarify new concepts for their students. However, analogies may inadvertently confuse the youngster who has difficulty identifying the one-to-one comparisons underlying them. Although analogical reasoning has been studied extensively in normal children, no information was available concerning this construct in children having a specific language impairment. Thus, it was unknown to what extent they might be deficient in analogical reasoning. Therefore, in the present study, 20 children ages 6--8 years (mean age = 7:6) having normal nonverbal intelligence but deficits in language comprehension were administered tasks of verbal and perceptual proportional analogical reasoning and a problem-solving task of functional analogical reasoning. Compared to a normal-language control group matched on the basis of chronological age and sex, the language-impaired group was deficient in all three tasks of analogical reasoning. However, when the factor of nonverbal intelligence was controlled statistically, the differences between the groups on each of the tasks were removed. Additional findings were that verbal proportional analogical reasoning was significantly correlated to perceptual proportional analogical reasoning and to functional analogical reasoning. Implications for assessment and intervention with young school-age language-impaired children are discussed.

AbstractResearch has shown that observing iconic gestures helps typically developing children (TD) and children with specific language impairment (SLI) learn new words. So far, studies mostly compared word learning with and without gestures. The present study investigated word learning under two gesture conditions in children with and without language impairment. Twenty children with SLI (age four), twenty age-matched TD children, and twenty language-matched TD children were taught words that were presented with either iconic or non-iconic gestures. Results showed that children of all groups benefited more successfully from observing iconic gestures for word learning. The iconic gesture advantage was similar across groups. Thus, observing iconic gestures prompts richer encoding and makes word learning more efficient in TD and language impaired children.
