Visual word recognition and reading are central to human communication. Still, literacy rates are declining, increasing the need for better reading education and interventions for readers with low skill levels. At the beginning of such developments, one must understand the cognitions underlying reading. Here, we combine presentations that provide current developments in reading research, investigating how language, script, and memory influence visual word recognition processes in behavior and brain activation. We will start with a study by Sabrina Turker, which investigates the influence of language and memory skills on reading disabilities. The second study, by Benjamin Gagl, examines the influence of which items are stored in the lexicon on orthographic processing in visual word recognition behavior and brain responses. The third study, by Amelie Hague, investigates script familiarity on brain response dynamics. The fourth study, by Maz Mohamed, analyzes how learning to read in different languages influences the process of lexical access. Finally, Jana Hasenäcker presents a large-scale study of German lexicon decision data, which is essential to exploring novel hypotheses built on consensus-based guidelines, embracing open science methodology. The symposium relies on behavioral and brain findings across studies using implemented theoretical approaches through computational models, and offers an overview of the availability of novel datasets. Thus, this symposium delivers a comprehensive update on the neuro-cognitive processes implemented in reading and visual word recognition, including current theoretical advancements.

Dyslexia is typically defined by difficulties in accurate and fluent word recognition, yet behavioural evidence suggests that these challenges extend across multiple linguistic and cognitive domains. Across several studies, we investigated how phonological awareness, verbal working memory, and speech production interact in shaping the behavioural profile of dyslexia. Children with dyslexia performed poorly on various language learning and working memory tasks, with major deficits in non-word span, phonetic memory and vocabulary learning. Especially children with additional attention deficits showed more severe working memory deficits and weaknesses in non-language domains. Follow-up research identified spelling, word reading, and phonological awareness as the strongest predictors of dyslexia in adults, alongside a markedly heterogeneous behavioural profile - even low-level deficits persisted into adulthood despite the shallow nature of the German orthographic system. Our most recent findings extend this framework to speech production: acoustic analyses show subtle but systematic differences in articulatory variability between adults with and without dyslexia. Specifically, individuals with dyslexia exhibited less distinct voicing contrasts and slightly reduced category compactness, suggesting persistent imprecision in phonetic implementation.
