- 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.

- Objective: Examine deaf and hard of hearing (DHH) children's phonological processing skills in relation to a reference group of children with normal hearing (NH) at two baselines pre intervention. Study the effects of computer-assisted phoneme-grapheme correspondence training in the children. Specifically analyze possible effects on DHH children's phonological processing skills.Methods: The study included 48 children who participated in a computer-assisted intervention study, which focuses on phoneme-grapheme correspondence. Children were 5, 6, and 7 years of age. There were 32 DHH children using cochlear implants (CI) or hearing aids (HA), or both in combination, and 16 children with NH. The study had a quasi-experimental design with three test occasions separated in time by four weeks; baseline 1 and 2 pre intervention, and 3 post intervention. Children performed tasks measuring lexical access, phonological processing, and letter knowledge. All children were asked to practice ten minutes per day at home supported by their parents.Results: NH children outperformed DHH children on the majority of tasks. All children improved their accuracy in phoneme-grapheme correspondence and output phonology as a function of the computer-assisted intervention. For the whole group of children, and specifically for children with CI, a lower initial phonological composite score was associated with a larger phonological change between baseline 2 and post intervention. Finally, 18 DHH children, whereof 11 children with CI, showed specific intervention effects on their phonological processing skills, and strong effect sizes for their improved accuracy of phoneme-grapheme correspondence.Conclusion: For some DHH children phonological processing skills are boosted relatively more by phoneme-grapheme correspondence training. This reflects the reciprocal relationship between phonological change and exposure to and manipulations of letters.

- 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.

- 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.

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.

Tidskriftsartikel (refereegranskat)abstract
- Twenty 10- to 18-year-old children and adolescents with varying degrees of hearing impairment (HI) and hearing aids (HA), ranging from mild-moderate to severe, produced picture-elicited narratives in a spoken and written version. Their performance was compared to that of 63 normally hearing (NH) peers within the same age span. The participants with HI and NH showed similar patterns regarding intragroup correlations between corresponding measures of spoken and written narratives. However, the participants with HI had significantly less diverse language than the NH group. The participants with poorer hearing (higher best ear hearing level [BEHL]) produced spoken and written narratives comprising more content words and they also produced written narratives that were less lexically diverse than the participants with better hearing (lower BEHL). The difference as to lexical skills emphasizes the importance of focusing on these skills in the group of children with HI. However, the results give support for a quite optimistic view on the development of narration in children with HI with HA, at least for picture-elicited narratives.

Tidskriftsartikel (refereegranskat)abstract
- The purpose of the study was to explore the narrative writing of 18 children, ages 11 to 19, with severe and profound hearing impairment who had cochlear implants (CI), compared with the performance of hearing children. Nine of the 18 children had prelingual deafness and 9 children had postlingual deafness. The hearing impairment was progressive in 11 children. The participants thus formed a heterogeneous group, which was split in two ways: according to age at testing and age at implantation. The narratives were collected by means of keystroke logging. The difference between the children with CI and the hearing children was most prominent for two measures: the percentage of pause time (in the group of children older than 13 years) and lexical density. Furthermore, the children implanted after 5 years of age performed more like the hearing children. This group consisted of children with postlingual deafness and also of children who were deafened progressively. Our interpretation is that these children benefited from the early linguistic input. Taking the whole group of participants into consideration, the results reflect linguistic and cognitive processing limitations in complex linguistic tasks like narration for the children with CI in comparison with their hearing peers.
