In this paper, we explore the performance of past-tense inflection of non-verbs (NVI) in children with developmental language disorder (DLD) and in typically developing controls, to investigate its accuracy as a clinical marker for Swedish-speaking children with DLD. Further, we investigate the relationship between NVI, nonword-repetition, and family history. The sample consists of 36 children with DLD (mean age 9;5 years) and 60 controls (mean age 9;2 years). The DLD group performed significantly lower than the controls on the NVI task, with a large effect size of the difference (d = 1.52). Analysis of the clinical accuracy of NVI resulted in 80.6% sensitivity and 76.6% specificity. NVI was significantly and moderately associated with nonword-repetition in the controls, but not in the DLD group. A positive family history, 80.6% in the DLD group and 6.9% in the controls, was associated with lower performance on NVI. When controlling for group (DLD and controls), a non-significant association between family history and performance on the NVI task was found. NVI is a potential clinical marker of DLD in Swedish school-aged children, but the current NVI task does not reach the level of being acceptable. Further development of the NVI task is warranted to improve its accuracy. [ABSTRACT FROM AUTHOR]

The aim of this pilot study was to evaluate two new retelling tasks intended for clinical use in terms of language sample size, effects of picture support, and order of presentation. Forty Swedish-speaking children in grades 4–6 participated in the study, 31 children with typical language development (TLD, mean age 11;1), and nine children with developmental language disorder (DLD, mean age 11;5). Two oral retells, one with and one without picture support, were analyzed with regards to productivity, syntactic complexity, basic Story Grammar (SG) units, and Internal Responses (IR). Results showed no systematic order effects in the TLD group, although this needs to be investigated further, and good inter-rater reliability. Both tasks elicited sufficiently large language samples, except from one participant with DLD whose samples were excluded from subsequent comparisons. When appropriate, data were analyzed with ANOVA (productivity, mean length of C-unit/MLCU), otherwise t-tests (TLD-group) or non-parametric tests (DLD-group) were used. As expected, retells from participants with DLD were shorter, with shorter MLCU and fewer SG units compared to the TLD group. There were also task effects: in the task with picture support, all participants had longer MLCU, and participants with TLD also showed a higher proportion of subordinate clauses, indicating that pictures may function as a support for syntactic complexity. The task without picture support, on the other hand, elicited more C-units indicated by a significant main effect, and more SG units, which was a significant effect in the TLD group. >We conclude that both tasks might be useful for Swedish speech-language pathologists.

Self-efficacy for writing is an important motivational factor and considered to predict writing performance. Self-efficacy for narrative writing has been sparsely studied, and few studies focus on the effects of writing intervention on self-efficacy. Additionally, there is a lack of validated measures of self-efficacy for elementary school students. In a previous study, we found that a trained panel rated personal narrative text quality higher for girls than for boys, which led to our aim: to investigate boys' and girls' self-efficacy for narrative writing before and after an intervention, and to explore associations between self-efficacy and text quality. An 18-item self-efficacy scale was developed. Fifty-five fifth-grade students (M 11:2 years, SD 3.7 months) filled out the scale before and after a five-lesson observational learning intervention. Self-efficacy was then related to writing performance as measured by holistic text quality ratings. The students demonstrated strong self-efficacy, which increased significantly post-intervention. Girls and boys demonstrated similar self-efficacy, despite girls' higher text quality. There were moderate correlations between self-efficacy and writing performance pre- and post-intervention. The results support previous findings of strong self-efficacy at this age. The interaction between writing self-efficacy and performance is complex. Young students may not be able to differentiate between self-efficacy, general writing skills, task performance, and self-regulation. Self-efficacy scales should thus be carefully constructed with respect to age, genre, instruction, and to students' general educational context. [ABSTRACT FROM AUTHOR]

Purpose: Children's results on school-related achievements tests, such as aspects of math, reading and writing, have been shown to decline following a lengthy summer vacation. Few studies have investigated whether this also applies to vocabulary skills. The purpose of this study is to investigate how lexical organization and retrieval, assessed by a semantic verbal fluency (SVF) task, develops during a lengthy summer vacation versus formal schooling. Method: Sixty-eight children with mean age of 7.9 (ranging from 6.5 to 9.1), were assessed pre- and post-summer vacation and post-fall semester using two SVF categories (Animals and Clothes). The number of words produced in both categories gave the total score. Results: The result of the SVF tests decreased following summer vacation. The loss was recouped at the post-fall semester assessment, but no gains compared to initial testing were shown. Neither level of parental education, general language ability, non-verbal IQ, nor bilingualism explained the variance in development during the summer vacation or the fall semester. Conclusions: Our findings indicate that a lengthy summer vacation causes a recess in the expected development of SVF ability and that this recess is recouped after a semester of formal schooling. The findings are in line with previous research indicating that summer vacation may have negative impact on the development of important scholastic abilities in children. [ABSTRACT FROM AUTHOR]

The study investigates the effect of voice quality and competing speakers on perceived effort in a passage comprehension task in relation to cognitive functioning. In addition, it explores if perceived effort was related to performance. A total of 49 children (aged 7:03 to 12:02 years) with normal hearing participated. The children performed an auditory passage comprehension task presented with six different listening conditions consisting of a typical voice or a dysphonic voice presented in quiet, with one competing speaker, and with four competing speakers. After completing the task, they rated their perceived effort on a five-grade scale. The children also performed tasks measuring working memory capacity (WMC) and executive functioning. The results show that voice quality had no direct effect on perceived effort but the children's ratings of perceived effort were related to their executive functioning. A significant effect was seen for background listening condition indicating higher perceived effort for background listening conditions with competing speakers. The effects of background listening condition were mainly related to the children's WMC but also their executive functioning. It can be concluded that the individual susceptibility to the effect of the dysphonic voice is related to the child's executive functioning. The individual susceptibility to the presence of competing speakers is related to the child's WMC and executive functioning. [ABSTRACT FROM AUTHOR]

Voice onset time (VOT) is a temporal acoustic parameter, which reflects the timing of speech motor control. The objective of the work was to obtain normative VOT data in Swedish children. Thus, 150 children aged 8-11 years old and 36 adults were audio-recorded when producing the plosives in minimal pairs. Measures were made using waveforms and spectrograms. Results show that Swedish children developed adult-like VOT values between 9 and 10 years. By the age of 10 years prevoicing was also found to be completely adultlike in length. The results indicate that all Swedish adults do not produce voiced plosives with prevoicing. No evident gender differences were found. The obtained VOT values can be used as normative data when assessing children with speech and language disorders. [ABSTRACT FROM AUTHOR]

Tonsillar hypertrophy is common in young children and affects several aspects of the speech such as distortions of the dento-alveolar consonants. The study objective was to assess /s/-articulation, perceptually and acoustically, in children with tonsillar hypertrophy and compare effects of two types of surgery, total tonsillectomy and tonsillotomy. Sixty-seven children, aged 50-65 months, on the waiting list for surgery, were randomized to tonsillectomy or tonsillotomy. The speech material was collected preoperatively and 6 months postoperatively. Two groups of age-matched children were controls. /S/-articulation was affected acoustically with lower spectral peak locations and perceptually with less distinct /s/-production before surgery, in comparison to controls. After surgery /s/-articulation was normalized perceptually, but acoustic differences remained. No significant differences between surgical methods were found. [ABSTRACT FROM AUTHOR]

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.

Based on data from 156 typically developing 10-12-year-olds from Sweden, reading comprehension skills were studied in three subgroups: those classified with specific poor word decoding skills ( n = 10), those with specific poor language comprehension ( n = 12), and those with mixed difficulties in word decoding and language comprehension ( n = 11). The mixed poor group achieved significantly lower scores than both specific groups in reading comprehension, and was the only group displaying poor reading comprehension test results relative to the performance of the full sample. Results are indicative of the necessity of a combined effect of poor word decoding and language in reading comprehension difficulties for this group. Implications and limitations are discussed.
