12 Understanding the structure of discourse in healthy adults is fundamental to the assessment and diagnosis of discourse level impairments in clinical populations and the development of effective treatment regimes. Exploring discourse genre in healthy speakers that extend beyond the traditional narrative is equally paramount in facilitating maximum impact of clinical interventions in everyday speaking contexts. This study aimed to characterise the discourse of 30 healthy adult speakers across three age groups (20-39, 40-59 and 60+ years) and four discourse genres (recount, procedural, exposition and narrative), drawing on discourse frameworks used in classroom teaching. A clinically useful discourse protocol and analytic procedure using SALT was developed that profiled the macrostructure and key aspects of linguistic microstructure of the different genres, exploring coherence and cohesion within and across genre in a systematic manner. Analyses considered whether there were differences in coherence and cohesion among the different age groups, different genres and specific topics. Results showed that, while individual variability was present, healthy adults structured their discourse consistently, adhering to the frameworks described in the developmental literature, across all four genres. Significant age differences were only seen in the amount of information contained in the body of the discourse (i.e. events, steps or statements offered) with older participants offering less information. This dataset will enable comparisons to be drawn with clinical populations to determine the utility and the feasibility of the use of this framework for diagnosis and intervention.

• Children with DLD experience significant difficulties only when learning longer novel words. • Phonological short-term memory deficits impact word learning in children with DLD. • Nonword repetition has predictive value in understanding word learning potential. To investigate factors that influence word learning in children with developmental language disorder (DLD). The participants were 23 children with DLD and 26 typically developing (TD) children, aged five. Participants completed a fast mapping task (assessed using a production measure), as well as tests of nonword repetition and receptive vocabulary. We explored the effect of word length on nonword repetition and fast mapping abilities while controlling for receptive vocabulary skills. The results indicate that children with DLD demonstrate significant difficulties accurately repeating nonwords of all lengths relative to their TD peers. Children with DLD also exhibited significant difficulties with fast mapping, especially when learning longer novel words. Our findings indicate that children with DLD demonstrate an impaired capacity to encode phonological information; however, this differentially impacts their nonword repetition and fast mapping abilities. TD children may more effectively take advantage of receptive vocabulary to support performance on these tasks. Readers will understand how phonological short-term memory and receptive vocabulary contribute to fast mapping in children with DLD and in TD children. [ABSTRACT FROM AUTHOR]

Although children with developmental language disorder demonstrate poor inferential comprehension, few studies have evaluated the effect of interventions to improve inferencing. This study aimed to investigate the efficacy of a small-group intervention designed to improve oral inferential comprehension of narrative discourse. Thirty-seven 5- to 6-year-old children with developmental language disorder participated. The participants were randomly allocated to the oral inferential comprehension (IC) intervention or a control phonological awareness (PA) intervention. Small-group sessions took place twice a week over 8 weeks. Participants were assessed on narrative comprehension and phonological awareness skills pre- and post-intervention, and after a maintenance period of 8 weeks. Compared to the control PA group, the participants in the IC group demonstrated a significant increase in inferential comprehension scores from pre- to post-intervention, which was maintained over time. In addition, the IC group scored significantly higher than the PA group for inferential comprehension on a post-intervention generalization measure. There was no significant difference between the two groups for literal comprehension scores at any assessment point. The results demonstrate that the small-group intervention was effective at improving inferential comprehension of narratives in 5- to 6-year-old children with developmental language disorder. Additionally, generalized improvement was shown across the narrative context, and improvements were maintained two months following the intervention. [ABSTRACT FROM AUTHOR]

Background: Children with developmental language disorder (DLD) demonstrate poor oral inferential comprehension. Research investigating the skills that underpin oral inferential comprehension in young children with DLD is necessary in order to better understand and improve inferential comprehension in this population. Aims: To profile the language and cognitive skills that contribute to oral inferential comprehension in young children with DLD. Methods & Procedures: Seventy‐six children aged 5–6 years with a diagnosis of DLD were assessed on a wide range of language and cognitive measures. Oral inferential comprehension of narrative was the primary outcome measure. Outcomes & Results: Narrative macrostructure and microstructure, literal comprehension, vocabulary, phonological loop, and theory of mind were significant predictors of inferential comprehension in bivariate analyses. However, multivariate regression analysis indicated that only narrative retell macrostructure and theory of mind contributed a significant amount of unique variance to inferential comprehension. Conclusions & Implications: This study profiled the skills contributing to oral inferential comprehension in young children with DLD, to support the clinical and theoretical understanding of the ability in this population. The findings have implications for future intervention studies. [ABSTRACT FROM AUTHOR]

Background Children with specific language impairment (SLI) often experience word-learning difficulties, which are suggested to originate in the early stage of word learning: fast mapping. Some previous research indicates significantly poorer fast mapping capabilities in children with SLI compared with typically developing (TD) counterparts, with a range of methodological factors impacting on the consistency of this finding. Research has explored key issues that might underlie fast mapping difficulties in children with SLI, with strong theoretical support but little empirical evidence for the role of phonological short-term memory (STM). Additionally, further research is required to explore the influence of receptive vocabulary on fast mapping capabilities. Understanding the factors associated with fast mapping difficulties that are experienced by children with SLI may lead to greater theoretically driven word-learning intervention. Aims To investigate whether children with SLI demonstrate significant difficulties with fast mapping, and to explore the related factors. It was hypothesized that children with SLI would score significantly lower on a fast mapping production task compared with TD children, and that phonological STM and receptive vocabulary would significantly predict fast mapping production scores in both groups of children. Methods & Procedures Twenty-three children with SLI (mean = 64.39 months, SD = 4.10 months) and 26 TD children (mean = 65.92 months, SD = 2.98) were recruited from specialist language and mainstream schools. All participants took part in a unique, interactive fast-mapping task whereby nine novel objects with non-word labels were presented and production accuracy was assessed. A non-word repetition test and the Peabody Picture Vocabulary Test-Fourth Edition (PPVT-IV) were also administered as measures of phonological STM capacity and receptive vocabulary, respectively. Outcomes & Results Results of the fast-mapping task indicated that children with SLI had significantly poorer fast mapping production scores than TD children. Scores from the non-word repetition task were also significantly lower for the SLI group, revealing reduced phonological STM capacity. Phonological STM capacity and receptive vocabulary emerged as significant predictors of fast mapping performance when the group data were combined in a multiple regression analysis. Conclusions & Implications These results suggest that the word-learning difficulties experienced by children with SLI may originate at the fast mapping stage, and that phonological STM and receptive vocabulary significantly predict fast mapping ability. These findings contribute to the theoretical understanding of word-learning difficulties in children with SLI and may inform lexical learning intervention. [ABSTRACT FROM AUTHOR]
