Phonology has been a central concept in the scientific study of dyslexia over the past decades. Despite its central position, however, it is a concept with no precise definition or status. The present article investigates the notion of "phonology" in the tradition of cognitive psychology. An attempt is made to characterize the basic assumptions of…

This study examined event-related potentials (ERPs) to synthetic consonant-vowel syllables from 26 newborns with familial risk for dyslexia and 23 control infants participating in a longitudinal study of dyslexia. Results indicated that the cortical electric activation evoked by speech elements differed between children with and without risk for…

"Sine-wave speech" sentences contain only four frequency-modulated sine waves, lacking many acoustic cues present in natural speech. Adults with (n=19) and without (n=14) dyslexia were asked to reproduce orally sine-wave utterances in successive trials. Results suggest comprehension of sine-wave sentences is impaired in some adults with…

Fourteen Dutch children with dyslexia were compared with controls on automatic processing under a dual task (motor balance task and auditory choice task) model. Results indicated the dyslexic group was more impaired in the dual task condition than in the single task condition, compared with controls. Findings support the automatization deficit…

Eighty-two elementary school children with attention deficit disorder (ADD) and dyslexia made more errors than 83 normally reading children with ADD on a test of rhyme and alliteration. A subgroup of dyslexic children who were sensitive to rhyme and alliteration scored higher than other dyslexic children on a test of spatial ability. (Author/DB)

This study examined the abilities of 18 adults with familial dyslexia to use steady state, dynamic, and temporal cues in synthetic speech continua. Although subjects were able to label and discriminate the continua, they did not necessarily use acoustic cues in the same manner as did normal readers, and their overall performance was less accurate.…

Describes three experiments that examined the processing of speech by dyslexic readers. Compares their performance with that of age-matched and reading-ability-matched controls. Shows that dyslexics have difficulty with the nonlexical procedures involved in verbal repetition. (HOD)
