Título: Perfiles de lectura en adolescentes con síndrome de X frágil y síndrome de Down. Resumen: Las personas con síndrome de X frágil (FXS) y con síndrome de Down (DS) leen mejor de lo esperado para su edad mental. Hemos medido tres habilidades básicas de lectura (reconocimiento de palabras, conciencia fonológica y comprensión de lectura), y dos medidas estándar intelectual y verbal: Escalas McCarthy de capacidades de los niños y los Peabody Picture Vocabulary Tests. Las pruebas se aplicaron a 16 adolescentes clasificados como FXS (M = 14.74 años, DT = 4.03) y 16 adolescentes clasificados como DS (M = 15.59 años, SD = 2.35). Para fines de comparación, las pruebas de lectura también se aplicaron a un grupo de desarrollo normal de 70 niños de entre 4.8 y 7 años (M = 6.11, DT = 0.71). Los niños con DS y FXS mostraron habilidades verbales superiores a su desarrollo cognitivo, especialmente en el grupo FXS. En el rendimiento de lectura, FXS mostraron un nivel de lectura correspondiente a 5/6 de su edad, y para SD 6/7 de la edad de lectura equivalente; sin embargo, ambos grupos mostraron un rendimiento de lectura similar en las tres habilidades de lectura medidas, cuando la edad mental no verbal fue controlada. Palabras clave: Síndrome de X frágil; síndrome de Down; discapacidad de aprendizaje, comportamiento cognitivo; habilidades de lectura. Abstract: Fragile X Syndrome (FXS) and Down Syndrome (DS) read better than expected for their mental age. We have measured three basic reading skills (word recognition, phonological awareness, and reading comprehension), and two standard intellectual and verbal measures: the McCarthy Scales of Children’s Abilities and Peabody Picture Vocabulary Tests. The tests were applied to 16 adolescents classified as FXS (M = 14.74 years old, SD = 4.03) and 16 adolescents classified as DS (M = 15.59 years old, SD = 2.35). For comparison purposes, the reading tests were also applied to a typical develop group of 70 children aged between 4.8 and 7.0 years (M = 6.11, SD = 0.71). Children with DS and FXS exhibited verbal skills superior to their cognitive development, especially in the FXS group. In reading performance, FXS showed a reading level corresponding to 5/6 their age, and for SD 6/7 of the equivalent reading age, however, both groups exhibited a similar reading performance in the three reading skills measured, when nonverbal mental age was controlled.
