Tidskriftsartikel (refereegranskat)abstract
- The present study investigated cognitive abilities (i.e. Phonological Processing Skills (PhPS), lexical access, complex and visual Working Memory (WM), and letter knowledge) in Deaf and Hard of Hearing children (DHH) 5, 6 and 7 years of age using cochlear implants or hearing aids. Children with Normal Hearing (NH) served as a reference group. All children took part of a computer-assisted intervention with a phonics approach for 4 weeks aimed to support PhPS. The first aim of the study was to examine associations between cognitive abilities and Phonological Processing Skills (PhPS) pre intervention in DHH and NH children respectively. The second aim was to examine cognitive predictors of phonological gain post intervention. Finally, the influence of background variables on phonological gain was examined in NH and DHH respectively and in DHH children with weak PhPS particularly. Results showed comparable performance level in NH and DHH children on the majority of cognitive tasks, but weaker PhPS and lexical access in the DHH children. A significant association between PhPS and complex WM was only evident in DHH children. This finding suggests that DHH recruit more cognitive resources in phonological processing. A phonological representation task was the single predictor of phonological gain in DHH children. Children with initial weak performance on this task but had letter-naming skills, displayed relatively more phonological gain from the phonics training. Children with difficulties with the phonological representation task were older when diagnosed and had an older age at amplification. Further, these children displayed broader cognitive difficulties, suggesting that reduced access to auditory stimulation may have wide ranging effects on cognitive development.

- Studies of language in children with mild-to-moderate hearing impairment ( HI) indicate that they often have problems in phonological shortterm memory (PSTM) and that they have linguistic weaknesses both in vocabulary and morphosyntax similar to children with specific language impairment (SLI). However, children with HI may be more likely than children with SLI to acquire typical language skills as they get older. It has been suggested that the more persisting problems in children with SLI are due to a combination of factors: perceptual, cognitive and/or linguistic. Aims: The main aim of this study was to explore language skills in children with HI in comparison with children with SLI, and how children with both HI and language impairment differ from those with non-impaired spoken language skills. Methods & Procedures: PSTM, output phonology, lexical ability, receptive grammar and verb morphology were assessed in a group of children with mild-to-moderate HI ( n=11) and a group of children with SLI (n=12) aged 5 years 6 months to 9 years 0 months. Outcomes & Results: The HI group tended to score higher than the SLI group on the language measures, although few of the differences were significant. The children with HI had their most obvious weaknesses in PSTM, vocabulary, receptive grammar and inflection of novel verbs. The subgroup of children with HI ( five out of 10) who also showed evidence of grammatical output problems was significantly younger than the remaining children with HI. Correlation analysis showed that the language variables were not associated with age, whereas hearing level was associated with PSTM. Conclusions: Children with HI are at risk for at least a delay in lexical ability, receptive grammar and grammatical production. The problems seen in the HI group might be explained by their low-level perceptual deficit and weak PSTM. For the SLI group the impairment is more severe. From a clinical perspective an important conclusion is that the language development in children with even mild-to-moderate HI deserves attention and support.

- The purpose of the present study was to investigate the relationship between perception and production of metrical patterns in Swedish children with language impairment (LI), in order to add to the knowledge on underlying explanations of LI. A further aim was to explore whether omissions are mainly related to prosodic aspects or to linguistic function. Children with LI omitted significantly more unstressed syllables than did children with typical language development. Exploration of the relationship between perception and production of phrasal stress patterns demonstrated that children with LI might be divided into three subgroups: Group a: children who perform better on perception than production; Group b: children who perform better on production than perception; and Group c: children with rather poor results on both perception and production.

- and profound hearing impairment treated by cochlear implants (CI). In this study we explore this relationship in sixteen Swedish children with CI. We found that over 60% of the children with CI performed at the level of their hearing peers in a reading comprehension test. Demographic factors were not predictive of reading comprehension, but a complex working memory task was. Reading percentile was significantly correlated to the working memory test, but no other correlations between reading and cognitive/linguistic factors remained significant after age was factored out. Individual results from a comparison of the two best and the two poorest readers corroborate group results, confirming the important role of working memory for reading as measured by comprehension of words and sentences in this group of children.

- In spite of earlier implantation, bilateral implants and advances in the care of deaf children with cochlear implants (CI) within-group variation in language skills is large. We use three tasks with predictive value of language impairment in Swedish to identify children with CI most at risk for persistent difficulties in language development, in need of language intervention. The clinical markers investigated are nonword repetition and past tense inflection. We also assessed language comprehension, a predictor of severe language impairment associated with poorer prognosis. Fifteen Swedish-speaking deaf children with CI and 15 controls aged 5–8 years participated. Most children with CI had bilateral implants and had been fitted with CIs before 12 months. At least 70% in the group with CI performed >1.25 and 47% >2 SD below controls on more than one measure, showing risk for persistent language impairment. Speech perception was more crucial in the nonword repetition and language comprehension tasks. No time factor was significantly related to outcome. We conclude that it is important to allocate resources for continuous follow-up and language intervention. Research and care of children with CI will profit from better integration of knowledge from the fields of audiology, speech-language pathology and linguistics.

Tidskriftsartikel (refereegranskat)abstract
- Twenty-seven children, with typical language development (TLD), 8-10 years old and 10-12 years old, were assessed with keystroke-logging in order to investigate their narrative writing. Measures of the writing process and the written product were used. One purpose was to explore how children produce written narratives in on-line production, and to relate the writing process to the written product. The results showed that those children who produced the final text faster, also wrote stories that comprised of more words. In the group of older children, children with better narrative ability used less pause time than those with worse ability, and the girls were faster writers than the boys. We believe that keystroke-logging gives valuable information for the assessment of young children's writing and that it is a potentially valid assessment tool for children from about 10 years of age.

Konferensbidrag (refereegranskat)abstract
- The purpose of the present article is to present an overview of a set of studies conducted in our own laboratory on cognitive and communicative development in children with cochlear implants (CI). The results demonstrate that children with CIs perform at significantly lower levels on the majority of the cognitive tasks. The exceptions to this trend are tasks with relatively lower demands on phonological processing. A fairly high proportion of the children can reach a level of reading comprehension that matches hearing children, despite the fact that they have relatively poor phonological skills. General working memory capacity is further correlated with the type of questions asked in a referential communication task. The results are discussed with respect to issues related to education and rehabilitation.

Semantic Processing in Deaf and Hard-of-Hearing Children : Large N400 Mismatch Effects in Brain Responses, Despite Poor Semantic Ability
- 2016

Tidskriftsartikel (refereegranskat)abstract
- Difficulties in auditory and phonological processing affect semantic processing in speech comprehension for deaf and hard-of-hearing (DHH) children. However, little is known about brain responses related to semantic processing in this group. We investigated event-related potentials (ERPs) in DHH children with cochlear implants (CIs) and/or hearing aids (HAs), and in normally hearing controls (NH). We used a semantic priming task with spoken word primes followed by picture targets. In both DHH children and controls, cortical response differences between matching and mismatching targets revealed a typical N400 effect associated with semantic processing. Children with CI had the largest mismatch response despite poor semantic abilities overall; Children with CI also had the largest ERP differentiation between mismatch types, with small effects in within-category mismatch trials (target from same category as prime) and large effects in between-category mismatch trials (where target is from a different category than prime), compared to matching trials. Children with NH and HA had similar responses to both mismatch types. While the large and differentiated ERP responses in the CI group were unexpected and should be interpreted with caution, the results could reflect less precision in semantic processing among children with CI, or a stronger reliance on predictive processing.
