Learning to read is one of the most important cognitive milestones in the human social environment. One of the most accepted models explaining such process is the Double-Route Cascaded Model. It suggests the existence of two reading strategies: lexical and sublexical. In the Spanish language there are some contradictions about how these strategies are applied for reading. In addition, there are only a few studies dealing with the analysis of shifts between them, achieving a fluent reading process. In this paper we use a reading task including words and pseudowords for characterizing the cost of shifting between reading strategies in children with developmental dyslexia and normal controls. Our results suggest the presence of both strategies in these two experimental groups. In controls, both strategies become more efficient in correspondence to the increased exposition to written material. However, in children with developmental dyslexia only the lexical strategy exhibits such improvement. Their also point to a low cost for shifting between strategies in controls and a much more significant one in children with developmental dyslexia, differentiating subgroups with distinct shifting patterns.El aprendizaje de la lectura constituye uno de los hitos cognitivos más importantes del entorno social humano. Uno de los modelos de lectura más aceptados ha sido el Modelo de Doble Ruta en Cascada que sugiere la existencia de dos estrategias de lectura: lexical y sublexical. En el idioma español existen datos contradictorios acerca de cómo se aplican estas estrategias y no hay estudios que describan cómo se realizan los cambios de una a otra para lograr una lectura fluida. En este trabajo utilizamos una tarea de lectura de palabras y pseudopalabras para caracterizar el costo de cambio de una a otra estrategia en niños buenos lectores y niños con dislexia del desarrollo. Nuestros resultados sugieren la presencia de ambas estrategias en los dos grupos. En los niños buenos lectores ambas estrategias se hacen más eficientes con el grado de exposición a la lectura. Sin embargo, en los niños disléxicos esto solo ocurre en la estrategia lexical. Además, indican que los niños buenos lectores desarrollan un bajo costo en el cambio de estrategia de lectura mientras que un subgrupo de niños disléxicos presenta un costo mayor, conformándose subgrupos con patrones diferentes de afectación selectiva. Palabras clave: estrategias de lectura, cambio, español, niños disléxicos.

met, score 1 did not meet criteria. The summation score of the 14 categories for each study was documented. Perfect score of 42 (14 categoriesx3) denoted all criteria were met. The median score was defined as the passing score. Results: The median was 35 and the calculated passing score was 83% (35/42 x100%583%). The overall inter-rater reliability between the auditors was 0.56. Conclusions: Our preliminary findings showed that 83% is the objective passing score for audit of Ultrasound radiographers' compliance to standard departmental protocol, clinical and technical competencies. The agreement between the auditors was moderate. The outcome of this audit might be affected by the subjective interpretation of the auditors. However this reflects the inherent nature of the modality.
