Non-word repetition in children with language impairment - pitfalls and possibilities

Specific language impairment has, although not without controversy, been considered as a consequence of a phonological memory deficit. Non-word repetition has been proposed as a reliable index of phonological memory and also as predictive of lexical and grammatical development in normally developing and language-impaired children. The main aim was to study the relationship between repetition of words and non-words and expressive language skills (phonology and grammar) in 27 5-year-old children with language impairment. The authors also wanted to explore the influence of lexical stress on repetition skills. The results showed that words were significantly easier to repeat than non-words and that non-word repetition skills were significantly correlated to phonological and grammatical development. The most important predictor of non-word repetition skills was output phonology. The conclusion is that non-word repetition is not a single, reliable index of phonological memory in preschool children with language impairment. Also, the influence of prosodic variables on segmental aspects of speech production should not be overlooked in non-word construction, since it was found that unstressed syllables were omitted six times more often in prestressed than in post-stressed positions of the words and non-words.

ADHD and language impairment A study of the parent questionnaire FTF (Five to Fifteen).

The parental questionnaire FTF (Five to Fifteen) was given to parents of 76 children (mean age 11 years) diagnosed with ADHD. About half of the children had at least once been referred to a speech- and language pathologist. Most of them had not received any intervention or follow-up. A factor analysis identified six problem areas, which explain close to 75% of the total variation: Cognitive Skills, Motor/Perception, Emotion/Socialisation/Behaviour, Attention, Literacy Skills and Activity Control. The majority of the children had pragmatic problems, which are associated with some of the core aspects of the ADHD symptoms, especially inattention and impulsiveness. Communication and language comprehension caused these children many more problems than expressive language. Problems of reading and writing were very frequent. IQ-score was associated with maths and reading/writing. Additional items reflecting language skills, in particular language comprehension and pragmatics, were also found in other domains in the FTF, mainly in Executive functions, Learning and Social skills. Problems with language and pragmatics thus seem to be associated with the typical problems with learning and social skills in children with ADHD.

Conversation versus narration in pre-school children with language impairment

The study focuses on two elicitation methods for language sampling in children with language impairment: conversation and narration. It has been noted in other studies on different clinical groups that language elicited in different speaking contexts varies in aspects such as MLU, fluency and syntactic complexity. The purpose of this study was to compare genre effects on different aspects of language production in a group of pre-school children with language impairment. The results show that there are differences in language production during conversation compared with narration. Intelligibility and fluency were found to be higher in conversation than in narration, whereas MLU in words was higher in narration. The narrative task elicited more phrasal expansions and grammatical morphemes per utterance than the conversation. However, the children used more complex verb forms in conversation than in narration. The results are discussed in relation to recent research.

Developmental perspectives on bilingual Swedish-Arabic children with and without language impairment: a longitudinal study.

BACKGROUND There is a need for studies on bilingual language acquisition in combination with language impairment (LI). The speech and language clinician must have tools to differentiate between problems depending on inadequate exposure to a language and problems depending on a LI. Another important issue is the pace of bilingual language acquisition relative to the severity of LI. AIMS To investigate grammatical development over 12 months in both languages in 10 Swedish-Arabic pre-school children with severe LI and 10 Swedish-Arabic pre-school children without LI. METHODS & PROCEDURES The children were matched for age, gender, exposure to Swedish dialect, and exposure to Arabic dialect. The developmental hierarchy predicted by Processability Theory was used in tests in both Swedish and Arabic. Processability Theory was used as a yardstick to measure grammatical development in both languages. OUTCOME & RESULTS Bilingual children, both with and without LI, developed grammatical structures in Swedish and Arabic in the same implicational way. Children with severe LI could develop two languages, although the pace of development was much slower in both languages. Bilingual children with severe LI were also more vulnerable to limited exposure of both their languages. CONCLUSIONS A developmental perspective is important to understand the nature of LI in bilingual children. The results also have implications for the assessment of language development in bilingual children with severe LI, since a hardly perceptible development over time is observed.

What's the story? Narration and comprehension in Swedish preschool children with language impairment

This study investigated the possibility of identifying narrative problems at an early age (5-year-old children with language impairment). Furthermore, we explored the relationship between the comprehension of a story and the ability to structure the contents of the same story in a group of preschool children with language impairment. The results showed that the participants did not exhibit age-appropriate narrative skills. We also found that good comprehension of the narrative is a prerequisite for the ability to produce a story with a content structure in a retelling task. Methodological issues are discussed and the clinical implications highlighted.

Contextual Influence On The Language Production Of Children With Speech/Language Impairment

To investigate the possible contextual variability of language and interaction, data from 10 children with speech/language impairment and three different types of conversational partners (a parent, a peer and a clinician) were collected. The dialogues were analyzed with respect to the characteristics of the dialogues as whole, to the dominance and the productivity of the three types of conversational partners, and to the productivity, fluency and grammatical structure of the language production of the children with speech/language impairment. Productivity was measured as mean length of utterance (MLU) in words, number of utterances, number of different words and proportion of complete and intelligible utterances. Fluency was measured as the proportion of utterances containing a maze. Grammatical structure was analysed with respect to the use of grammatical morphemes, word order patterns, the occurrence of expansions and the complexity of verb forms. Significant differences, in particular between child-child and adult-child dialogues were found. The adult-child dialogues were asymmetrical, where the adults dominated through asking many questions and talking much. The peer dialogues were more dynamic and equal. In these dialogues the children with speech/language impairment took a more active role as a conversational partner. The children produced more utterances and different words with the adult partners, but variables related to fluency and grammatical structure did not vary as a function of the conversational partner. The results imply that children with speech/language impairment practise different aspects of their communicative ability with different types of conversational partners. In particular, it is important to provide them with opportunities to interact with peers, in order for them to develop their skills as independent conversational partners.

Context and comprehension: a neurolinguistic and interactional approach to the understanding of semantic-pragmatic disorder

In the present study we provide thorough descriptions of two children with a semantic-pragmatic disorder, a subgroup within the group of specific and severe developmental language disorders, from a neurolinguistic and interactional perspective. We argue that the pragmatic problems, at least in these two girls, are most probably secondary to their semantic/conceptual deficit. If sufficient contextual cues are provided comprehension is improved and, as a consequence, the pragmatic problems are reduced.

Language comprehension and non-word repetition in children with language impairment

Non-word repetition has, not without controversy, been considered a reliable index of phonological memory in children with language impairment (LI). Recent studies do, however, emphasize the strong link between non-word repetition skills and phonological output in pre-school children with LI. The purpose of the present study was to explore the relationship between non-word repetition and different aspects of language comprehension (comprehension of words, sentences and fables) in 27 children with LI. The results showed that non-word repetition significantly correlated with all measures of language comprehension in the children with LI. Partial correlations revealed a weaker relationship between vocabulary comprehension, comprehension of fables and non-word repetition than between non-word repetition and comprehension of grammar. A possible explanation for the findings may be that the tests assessing comprehension of grammar strained language processing and storage more than the other tests. It is concluded that non-word repetition cannot be considered to be a single, reliable index of phonological memory in pre-school children with LI. Non-word repetition incorporates a range of processes necessary for language comprehension and production, and thus mirrors the general language status of the child. (Less)

Indefinite articles and definite forms in Swedish children with specific language impairment

In many languages, children with Specific Language Impairment (SLI) show frequent omission of articles. Most articles in these languages are weak monosyllables. In Swedish, indefinite articles are prosodically comparable to articles in other languages, but definiteness is usually expressed through a suffix. We examined the use of articles in Swedish-speaking children with SLI in spontaneous data and a probe task. Children with SLI produced definite suffixes as accurately as control children. Indefinite articles were more problematic. In constructions in which an article must be supplied, the children with SLI omitted articles more frequently than the controls. We conclude that prosody contributes to the difficulty with articles. However, several details in the data indicated the added influence of lexical and/or grammatical factors.

Language impairment in Swedish bilingual children: a comparison between bilingual and monolingual children in Malmö.

In this study two groups of children were compared, 192 bilingual and 246 monolingual, referred over a 12‐mo period to University Hospital in Malmo for suspected language impairment. Compared with monolingual children, bilingual children ran a significantly lower risk (RR = 0.76, p < 0.0001) of being referred by a child health centre, and a significantly higher risk (RR = 1.54, p < 0.0103) of being referred after 5 y of age. In the bilingual group there was also a significantly higher risk of parental refusal of assessment (RR = 2.35, p<0.0016) and of the children being diagnosed with a severe language impairment (RR=1.87, p<0.0009). The risk for bilingual children with severe language impairment being discharged owing to non‐attendance was high (RR = 6.20, p < 0.0002) compared to monolingual children. The risk increased with severity of language impairment.
