Special Issue Information

Dear Colleagues,

Dyslexia and Developmental Language Disorder (DLD) are among the most prevalent neurodevelopmental disorders, profoundly influencing communication, literacy, academic achievement, and socio-emotional well-being. Dyslexia is primarily characterized by persistent difficulties in reading and spelling, while DLD involves significant impairments in oral language comprehension and production. These disorders frequently co-occur, creating complex challenges for researchers and clinicians aiming to disentangle their unique and shared features. Although substantial progress has been made in understanding the cognitive, linguistic, and neural foundations of these disorders, critical gaps remain, particularly in exploring their interactions and impacts across diverse languages and sociocultural contexts.

This Special Issue seeks to advance our understanding of dyslexia and DLD by addressing their developmental pathways, underlying mechanisms, and evidence-based approaches to diagnosis and intervention, both independently and in co-occurring presentations. We invite submissions that explore phonological, morphological, syntactic, and executive function processes, as well as the development of oral and written language skills. Research on cognitive comorbidities, neurobiological bases, and the role of environmental and cross-linguistic factors is also welcome.

Manuscripts may include original empirical studies, systematic reviews, meta-analyses, theoretical models, or intervention trials. Contributions featuring cross-cultural perspectives, diverse populations, or innovative methodologies—such as artificial intelligence and machine learning—are especially encouraged. By integrating insights from these varied approaches, this Special Issue aims to deepen our understanding of dyslexia and DLD and promote more effective strategies for identification and intervention.

We look forward to receiving contributions that bridge research, theory, and clinical practice, ultimately improving outcomes for individuals living with these conditions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Behavioral Sciences is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Past research has extensively explored reading in English-speaking children with dyslexia who acquire a highly irregular and opaque orthography. Far less is known about the manifestation of dyslexia in shallow, highly consistent orthographies like German, especially in adults. To shed further light on the heterogenous manifestation of dyslexia in German-speaking adults, we assessed reading and reading-related abilities, spelling, cognitive abilities, and language learning experience in 33 healthy German-speaking adults (17 females) and 33 adults with dyslexia (20 females). The four main aims were to (1) elucidate the intricate relationship between cognitive and literacy abilities, (2) investigate persisting weaknesses, (3) determine the strongest predictors of dyslexia, and (4) investigate deficit profiles. Group comparisons revealed persistent deficits in almost all measures of reading and spelling, slight deficits in verbal working memory, but no visuospatial impairments in adults with dyslexia. Moreover, adults with dyslexia had considerably lower English skills and lower educational attainment. Overall, we found fewer and weaker links between literacy and cognitive measures in adults with dyslexia, indicating a dissociation between these skills. Spelling, word reading, and phonological awareness were the best predictors of dyslexia, but the most widespread deficit was rapid automatized naming. Our findings suggest a heterogeneous manifestation of dyslexia in German-speaking adults, with even low-level deficits persisting into adulthood despite the shallow nature of the German orthographic system.
