title: Sound localization and word discrimination in reverberant environment in children with developmental dyslexia.
abstract: OBJECTIVE
  Compare if localization of sounds and words discrimination in reverberant environment is different between children with dyslexia and controls.
  
  
  METHODS
  We studied 30 children with dyslexia and 30 controls. Sound and word localization and discrimination was studied in five angles from left to right auditory fields (-90o, -45o, 0o, +45o, +90o), under reverberant and no-reverberant conditions; correct answers were compared.
  
  
  RESULTS
  Spatial location of words in no-reverberant test was deficient in children with dyslexia at 0º and +90o. Spatial location for reverberant test was altered in children with dyslexia at all angles, except -90o. Word discrimination in no-reverberant test in children with dyslexia had a poor performance at left angles. In reverberant test, children with dyslexia exhibited deficiencies at -45o, -90o, and +45o angles.
  
  
  CONCLUSIONS
  Children with dyslexia could had problems when have to locate sound, and discriminate words in extreme locations of the horizontal plane in classrooms with reverberation.
