The objective was to determine which language tests effectively identify SLD in TE children and establish optimal threshold values. The prospective study included 301 children 7–16 years, divided into three groups: GC without SLD (<i>n</i> = 71), TE children (<i>n</i> = 114), and non-gifted children with SLD (<i>n</i> = 116). Language test performances were compared across groups, and Classification and Regression Tree (CART) analyses were employed to optimize test sensitivity and specificity in the TE group. TE children performed better than the SLD group but worse than GC without disorders. At standard thresholds, text reading and spelling tests showed the highest sensitivity, which significantly improved when CART-derived decision thresholds (62nd and 38th percentiles) were applied, while maintaining satisfactory specificity. Results indicate that standard thresholds lead to under-identification of SLD in GC, and that adjusted thresholds enhance identification accuracy.

This study investigates the psycho-educational challenges of dyslexic children during the pandemic, highlighting the need for targeted interventions to support them in current and future contexts. This systematic review identified relevant articles through electronic searches of PubMed, Wiley, Scopus, Web of Science, Google Scholar, and ScienceDirect, supplemented by the snowballing technique, which involved examining the bibliographies of retrieved references. The study identified two main categories of challenges for dyslexic children: psychological (mental health, emotional well-being, behavioural issues, parental stress) and educational (socioeconomic status, technology access, special educational needs, teacher support, remote learning difficulties) affecting children with learning disabilities. The research results show that dyslexic children faced various psychological and educational difficulties identified in this review during the COVID-19 pandemic.

Performance followed a consistent gradient: identical words were easiest; unique words hardest; cognates fell between. This hierarchy held across both receptive and expressive tasks and remained stable over development; the Grade × Word Type interaction was non-significant, indicating that distance-related constraints remain stable with schooling. More telling was the Group × Word Type interaction: the performance gap between typically developing (TD) and learning-disabled (LD) children widened disproportionately for unique words, where the demands of representational construction meet reduced phonological processing resources. A modality asymmetry further qualified the picture: expressive vocabulary proved more sensitive to diglossic distance than receptive vocabulary, consistent with the heavier retrieval demands production places on underspecified representations. Theoretically, the findings are interpreted within MAWRID, which treats linguistic distance as a constraint on representational quality and the Lexical Quality Hypothesis, which links representational precision to lexical access efficiency. These findings implicate lexico-phonological distance as a structural, developmentally persistent constraint on lexical acquisition in Arabic diglossia, with disproportionate consequences for children with compromised phonological resources.</p>\u0000 </div>","PeriodicalId":47222,"journal":{"name":"Dyslexia","volume":"32 3","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148647812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
