Detección temprana de la dislexia mediante el reconocimiento de voces
Un aspecto clave para la intervención educativa específica es la detección temprana de niños con riesgo de dislexia. En este trabajo presentamos una sencilla tarea conductual de asociación de voces (modalidad auditiva) con avatares (modalidad visual), en la que las personas con dislexia muestran un rendimiento más bajo que las personas normo-lectoras. Dicho patrón de datos ocurre no solamente con lectores adultos, sino también con niños. Por tanto, esta tarea de integración multisensorial puede ser empleada como un marcador de la dislexia, en conjunto con otras tareas (v.g., conocimiento fonológico).
Ability for Voice Recognition Is a Marker for Dyslexia in Children
A recent voice recognition experiment conducted by Perrachione, Del Tufo, and Gabrieli (2011) revealed that, in normal adult readers, the accuracy at identifying human voices was better in the participants’ mother tongue than in an unfamiliar language, while this difference was absent in a group of adults with dyslexia. This pattern favored a view of dyslexia as due to “fundamentally impoverished native-language phonological representations.” To further examine this issue, we conducted two voice recognition experiments, one with children with/without dyslexia, and the other with adults with/without dyslexia. Results revealed that children/adults with dyslexia were less accurate at identify…
Struggling with L2 alphabet: The role of proficiency in orthographic learning
The present study examined the process of L2 orthographic learning in bilinguals with distant L1–L2 orthographies. Chinese–English bilinguals with various English proficiency levels were trained with novel L2 words during a reading task. In contrast to higher proficient learners, those with lower L2 proficiency exhibited increased effects of length, frequency, and lexicality across exposures and at-chance recognition of trained words. Importantly, an additional post-training task assessing the lexical integration of trained words evidenced the engagement in different L1–L2 reading strategies across different levels of L2 proficiency, hence suggesting the L1 holistic processing at the base …
