    Exploring the Predictive Role of Lexical Stress Discrimination in the Phonological and Grammatical Skills of Teenagers With Down Syndrome
    (Wiley, 2025-10-02) Lopez-Rioboo Moreno, Elena Alfonsa; Martínez Castilla, Pastora
    Background Temporal-sampling theory suggests that lexical stress discrimination plays an important role in language disorders. This study explored whether this is also the case in Down syndrome (DS) and, particularly, whether lexical stress discrimination could contribute to accounting for the phonological and grammatical skills of teenagers with this syndrome. Method Lexical stress discrimination, along with a range of phonological and grammatical skills, was assessed in a group of 27 teenagers with DS. The differential predictive role of lexical stress discrimination in phonology and grammar was studied, taking into account the potential effect of other relevant variables, namely, hearing thresholds, verbal short-term memory, chronological age and non-verbal cognition. Results Regression models revealed that, for the phonological measurements, only verbal short-term memory emerged as a significant predictor. For grammatical integration and sentence repetition, both verbal short-term memory and lexical stress discrimination played a predictive role. For grammar comprehension, lexical stress discrimination was the only significant predictor. Conclusions The results regarding grammar are consistent with a temporal-sampling framework. Given the observed predictive role of lexical stress discrimination in the grammatical skills of teenagers with DS, this prosodic skill could potentially be examined and incorporated as a prospective target in intervention programmes.

    Psycholinguistic profile of young adults with Down syndrome
    (Elsevier, 2019-11-01) Lopez-Rioboo Moreno, Elena Alfonsa; Martínez Castilla, Pastora; Department of Developmental and Educational Psychology, UNED
    Background The phenotype of Down syndrome (DS) is usually characterized by relative strengths in visual skills and severe deficits in auditory processing; this has consequences for language and communication. To date, it is not known whether this pattern characterizes the psycholinguistic profile of young adults with DS. Aims This study aimed to assess whether, relative to their cognitive level, young adults with DS present a specific and homogeneous phenotype for both auditory and visual psycholinguistic skills. Methods and procedures Fifty young adults with DS and 50 peers with other intellectual disability (ID) were equated in chronological age and nonverbal cognition and were compared regarding their performance in auditory and visual psycholinguistic functions. Outcomes and results Participants with DS showed more phenotypic-specific deficits in auditory psycholinguistic skills than in those involved in visual processing. However, phenotypic-specific impairments in visual psycholinguistic skills were also observed, while no significant between-group differences were found for some auditory psycholinguistic skills. Conclusions and implications The psycholinguistic pattern of young adults with DS is not homogeneous with respect to auditory and visual processing. The profile of specific deficits suggests that the educative support for young adults with DS may need to be specific.
