Data from a Sentence Repetition Task was used to investigate if there is an implicational order according to Processability Theory (PT) in grammatical structures produced by school-age children with DLD. PT is a cognitive theory of language development that assumes five implicational stages of morphosyntactic development. The analysis was based on a selection of sentences representing the different PT stages. The participants (n = 49; 6;5-11;5 years of age) were recruited from school language units for children with DLD. The results confirm an implicational order: the participants produced structures from a higher stage only if they also produced structures from lower stages. It is suggested that the developmental hierarchy can be used in the intervention of children with DLD by focusing on the next stage. Also, only 26.5% of the participants achieved PT stage 4, and one child (2%) reached the highest PT stage 5. This is discussed in relation to what is known regarding PT stages in typically developing children, as well as associations with language, memory, and non-verbal measures.","PeriodicalId":49219,"journal":{"name":"Clinical Linguistics & Phonetics","volume":" ","pages":"1-14"},"PeriodicalIF":0.8,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144005435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our study purpose was to determine whether either or both diagnostic groups simplify the phonemic content for words they repeat during a typical motor speech evaluation.Method: 195 people with aphasia after stroke were assigned to four diagnostic groups based on quantitative metrics of core speech criteria for AOS and APP. In addition to the target groups, the sample was divided into a borderline group with equivocal feature combinations (BL) and a group with minimal sound production errors (MIN). Monosyllabic, disyllabic, and multisyllabic words were transcribed phonetically and scored for phonemic complexity. The ratio of produced complexity relative to target complexity - the word complexity measure (WCM) ratio - was compared across groups.Results: According to the WCM ratio, participants in all four groups, including the group with minimal speech sound involvement, simplified more productions than they complicated. Those who produced the most speech sound errors also displayed greater phonemic simplification.Discussion: People with stroke-induced aphasia sometimes produce words that are phonemic complications of targets, but more often they simplify the phonemic output. We conclude that phonemic simplification at the word level has limited value for differentiating clinically between AOS and APP. Future research should consider comparing alternative simplification measures.","PeriodicalId":49219,"journal":{"name":"Clinical Linguistics & Phonetics","volume":" ","pages":"1-19"},"PeriodicalIF":0.8,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143992323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kinematic studies in this area have focused on children under 10, but adolescents' speech and the attainment of adult-like motor control remains under-researched. This review includes studies using instrumental techniques such as Ultrasound Tongue Imaging (UTI), Electropalatography (EPG) and Electromagnetic Articulography (EMA) to measure spatial and temporal articulatory features using a variety of metrics. Studies show greater articulatory variability in children compared to adults; however, inconsistencies in methodologies and participant samples limit the ability to synthesise findings effectively. Future research should focus on longitudinal studies spanning childhood and adolescence, using techniques that are easily incorporated into clinical practice. A detailed understanding of typical articulatory variability across different age ranges is crucial for identifying speech disorders and improving clinical interventions.","PeriodicalId":49219,"journal":{"name":"Clinical Linguistics & Phonetics","volume":" ","pages":"1-23"},"PeriodicalIF":0.8,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144005438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-nine individuals (12 with LHD, 8 with RHD and 9 hCs) provided elicited discourse samples during four tasks (free speech, picture description, story narrative and procedural tasks) from TalkBank (AphasiaBank and RHDBank). Familiar expressions were categorised into two broad types: nuanced (conveying emotional or attitudinal meaning) and non-nuanced (literal and speech-flow enhancing). Results showed that individuals with LHD produced more familiar expressions, especially nuanced ones, than those with RHD or HCs. A correlation was found between aphasia severity and the production of familiar expressions, with individuals who had more severe language impairments producing a higher proportion of familiar expressions in some tasks. No significant task differences in familiar expression production were observed among the groups. This study revealed that brain damage affects the production of familiar expressions, with individuals with LHD using them more frequently and in a more nuanced manner. In contrast, individuals with RHD had difficulty producing familiar expressions. Clinically, this underscores the importance of considering hemisphere-specific deficits when assessing and treating language impairments in individuals with brain damage, as therapies may need to be tailored to address the distinct challenges faced by individuals with LHD versus RHD.","PeriodicalId":49219,"journal":{"name":"Clinical Linguistics & Phonetics","volume":" ","pages":"1-20"},"PeriodicalIF":0.8,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143796839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unusual processes were less frequent than typical processes, although two unusual processes, unusual cluster reduction and palatalisation of /s/ were also present in the speech of 10% or more children in one of the three datasets.

A profile of speech and language skills associated with this developmental syndrome is yet to be described in the literature. In order to address this gap, this study presents the case of an 18-year-old man with Watson syndrome and reports both standardised and naturalistic assessments of speech, language, oro-motor skills, and semantic and phonemic fluency. Analyses included norm-referencing, discrepancy comparison, phonological process analysis, and acoustic analyses of voice and conversational fluency. The participant's semantic fluency approximated to the 84th percentile and the vocabulary, voice, and receptive language measures were within standard normative range. In contrast, expressive language difficulties and articulatory difficulties associated with impaired oro-motor skills were apparent. Specific tongue-motor difficulty impeded oral diadochokinesis, with gliding, stopping, and cluster reduction among the phonological processes observed to mitigate oro-motor difficulties. Language scores were lowest on tasks of working memory, syntax, and pragmatics, however neither syntax nor pragmatics presented increased difficulty in naturalistic conversation, indicating an influence of reduced working memory on language performance. The absence of explicit cognitive or communicative difficulty suggests specific speech and language difficulties. To conclude, the findings are discussed from both clinical and theoretical perspectives. Watson syndrome and the aetiology of communication difficulties are suggested as directions for future research, to validate these findings and diversify understanding of inclusive communication approaches.","PeriodicalId":49219,"journal":{"name":"Clinical Linguistics & Phonetics","volume":" ","pages":"1-24"},"PeriodicalIF":0.8,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143617803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, engaging children with ASD in such activities is not straightforward and often fraught with challenges. Yet we know very little about how practitioners cope when the interaction breaks down, for example, due to misunderstandings or failures to engage. This study employs a conversation analytic approach to uncover therapists' intricate practices for managing breakdowns in therapeutic interactions. Over 200 hours of naturally occurring interactions between seven Mandarin-speaking children and their therapists were recorded and analysed. Using Conversation Analysis, we identified and analysed 1062 directive turns issued by therapists and subsequent responses of the children. The findings are in three aspects: 1) A crucial and effective premise for increasing engagement and improving the quality of therapeutic interactions lies in recognising, ascribing and utilising the specific interactive modes of children with ASD, including their repeated utterances and prosodic resources. 2) Therapists' strategies are successful when they flexibly address and adapt the format of directives through tailored verbal iteration and embodied solicitation. 3) The importance of timing underscores the increased opportunities to positively influence turn-taking in children with ASD. It is proposed that practitioners can enhance their understanding of children with ASD by incorporating the profiling of interaction into their assessments and interventions, adapting ways to align with the unique patterns of children with ASD.","PeriodicalId":49219,"journal":{"name":"Clinical Linguistics & Phonetics","volume":" ","pages":"1-28"},"PeriodicalIF":0.8,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143574234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multiple-linear regression analyses (syntactic complexity, GAI, AQ, sex, and group status as predictors) showed that (a) syntactic complexity predicted total and stuttering-like disfluencies and stuttering severity, (b) GAI predicted typical disfluencies, and (c) sex predicted total, typical, and stuttering-like disfluencies. Additional correlation analyses revealed negative association between PRI and disfluencies in the control group but not in the autistic group. No connection was found between AQ and disfluencies.
