Purpose In this study, the authors aimed to investigate how differences in language ability relate to differences in processing talker information in the native language and an unfamiliar language by comparing performance for different ages and for groups with impaired language. Method Three groups of native English listeners with typical language development (TLD; ages 7–9, ages 10–12, adults) and 2 groups with specific language impairment (SLI; ages 7–9, ages 10–12) participated in the study. Listeners heard pairs of words in both English and German (unfamiliar language) and were asked to determine whether the words were produced by the same or different talkers. Results In English, talker discrimination improved with age. In German, performance improved with age for the school-age children but was worse for adult listeners. No differences were found between TLD and SLI children. Conclusion These results show that as listeners' language skills develop, there is a trade-off between more general perceptual abilities useful for processing talker information in any language and those that are relevant to their everyday language experiences and, thus, tied to the phonology. The lack of differences between the children with and without language impairments suggests that general auditory processing may be intact in at least some children with SLI.

AbstractDeficits in lexical access in children with specific language impairments (SLI) have been inferred from word naming, recall, and categorization tasks, but no evidence exists concerning these children's ability to identify words in spoken input. We presented successive auditory time gatings of unfamiliar words; familiar, phonologically related words; and familiar, phonologically unrelated words to school-age children with and without SLI. The groups did not differ significantly in the point at which they recognized familiar words, but the subjects with SLI required significantly more of the acoustic-phonetic signal than did their peers to recognize unfamiliar words. For all word types, the subjects with SLI were significantly less likely to respond with correct initial consonants at the earliest gated interval than were their peers. Our results suggest that both representational and perceptual inefficiencies may contribute to slowed lexical access in children with SLI.

Primary Measure

Intervention rates for children with language impairments vary widely across reports. Unfortunately, many language tests focus on areas of language that are not problematic for children with language impairments (LI). Over twenty years of research supports limitations in finiteness as a clinical marker of LI. However, speech language pathologists (SLPs) have been reluctant to include assessments of finiteness in clinical decisions for young school-age children. This article addresses the operational definition of finiteness which may have created a barrier to its clinical use. We recommend that SLPs include the Test of Early Grammatical Impairment as a primary measure of finiteness for identifying language impairment in children between 3 and 8 years of age because of its clinical flexibility and high levels of sensitivity and specificity.

This study examined Quick Incidental Learning (QUIL) of novel vocabulary by two groups of school-age children, those who were developing language normally and those who demonstrated a specific language impairment (SLI). The experimental items consisted of 20 words that referred to one of four semantic classes: object, attribute, action, and affective state. Videotaped stories were used to introduce the novel words, and word learning was measured by a picture-pointing task. For the normally developing children, the results documented a robust ability to learn words in the early school years. Comprehension gains were observed for all four word types, with the greatest gain made on the object labels. The children with SLI also demonstrated some word-learning ability, but their gain was significantly less than that of their normally developing peers. Although the general pattern of word effects was similar across the two groups, the children with SLI demonstrated a particularly low gain on words from the action class.

Frequency Changes

Background: Frequency discrimination is often impaired in children developing language atypically. However, findings in the detection of small frequency changes in these children are conflicting. Previous studies on children’s auditory perceptual abilities usually involved establishing differential sensitivity thresholds in sample populations who were not tested for auditory deficits. To date, there are no data comparing suprathreshold frequency discrimination ability in children tested for both auditory processing and language skills. Purpose: : This study examined the perception of small frequency differences (Δf) in children with auditory processing disorder (APD) and/or specific language impairment (SLI). The aim was to determine whether children with APD and children with SLI showed differences in their behavioral responses to frequency changes. Results were expected to identify different degrees of impairment and shed some light on the auditory perceptual overlap between pediatric APD and SLI. Research Design: An experimental group design using a two-alternative forced-choice procedure was used to determine frequency discrimination ability for three magnitudes of Δf from the 1000-Hz base frequency. Study Sample: Thirty children between 10 years of age and 12 years, 11 months of age: 17 children with APD and/or SLI, and 13 typically developing (TD) peers participated. The clinical groups included four children with APD only, four children with SLI only, and nine children with both APD and SLI. Data Collection and Analysis: Behavioral data collected using headphone delivery were analyzed using the sensitivity index d′, calculated for three Δf was 2%, 5%, and 15% of the base frequency or 20, 50, and 150 Hz. Correlations between the dependent variable d′ and the independent variables measuring auditory processing and language skills were also obtained. A stepwise regression analysis was then performed. Results: TD children and children with APD and/or SLI differed in the detection of small-tone Δf. In addition, APD or SLI status affected behavioral results differently. Comparisons between auditory processing test scores or language test scores and the sensitivity index d′ showed different strengths of correlation based on the magnitudes of the Δf. Auditory processing scores showed stronger correlation to the sensitivity index d′ for the small Δf, while language scores showed stronger correlation to the sensitivity index d′ for the large Δf. Conclusion: Although children with APD and/or SLI have difficulty with behavioral frequency discrimination, this difficulty may stem from two different levels: a basic auditory level for children with APD and a higher language processing level for children with SLI; the frequency discrimination performance seemed to be affected by the labeling demands of the same versus different frequency discrimination task for the children with SLI.

Longitudinal Twin Study

Purpose The goal of this study was to investigate the etiologic basis for the association between deficits in phonological memory (PM) and vocabulary in school-age children. Method Children with deficits in PM or vocabulary were identified within the International Longitudinal Twin Study (ILTS; Samuelsson et al., 2005). The ILTS includes 1,045 twin pairs (between the ages of 5 and 8 years) from the United States, Australia, and Scandinavia. The authors applied the DeFries-Fulker (DeFries & Fulker, 1985, 1988) regression method to determine whether problems in PM and vocabulary tend to co-occur because of overlapping genes, overlapping environmental risk factors, or both. Results Among children with isolated PM deficits, the authors found significant bivariate heritability of PM and vocabulary weaknesses both within and across time. However, when probands were selected for a vocabulary deficit, there was no evidence for bivariate heritability. In this case, it appears that the PM–vocabulary relationship is caused by common shared environmental experiences. Conclusions The findings are consistent with previous research on the heritability of specific language impairment and suggest that there are etiologic subgroups of children with low vocabulary for different reasons, 1 being more influenced by genes and another being more influenced by environment.

Purpose Compared with same-age typically developing peers, school-age children with specific language impairment (SLI) exhibit significant deficits in spoken sentence comprehension. They also demonstrate a range of memory limitations. Whether these 2 deficit areas are related is unclear. The present review article aims to (a) review 2 main theoretical accounts of SLI sentence comprehension and various studies supporting each and (b) offer a new, broader, more integrated memory-based framework to guide future SLI research, as we believe the available evidence favors a memory-based perspective of SLI comprehension limitations. Method We reviewed the literature on the sentence comprehension abilities of English-speaking children with SLI from 2 theoretical perspectives. Results The sentence comprehension limitations of children with SLI appear to be more fully captured by a memory-based perspective than by a syntax-specific deficit perspective. Conclusions Although a memory-based view appears to be the better account of SLI sentence comprehension deficits, this view requires refinement and expansion. Current memory-based perspectives of adult sentence comprehension, with proper modification, offer SLI investigators new, more integrated memory frameworks within which to study and better understand the sentence comprehension abilities of children with SLI.
