The performance of 14 poor readers on an audiovisual speech perception task was compared with 14 normal subjects matched on chronological age (CA) and 14 subjects matched on reading age (RA). The task consisted of identifying synthetic speech varying in place of articulation on an acoustic 9-point continuum between /ba/ and /da/ (Massaro & Cohen, 1983). The acoustic speech events were factorial...

Auditory recognition memory in non-human primates is not well understood. Monkeys have difficulty acquiring auditory memory tasks, and limited capability maintaining auditory information over memory delays, relative to studies of visual memory. Neural substrates of auditory discrimination and recognition memory depend on superior temporal gyrus (STG), instead of rhinal cortex necessary for visu...

Previous research suggests that with increasing age children become more efficient in inhibiting conflicting responses and in resisting interference from irrelevant information. We assessed the abilities of 100 children (ages 3-16 years) and 20 adults to resist interference during the processing of 2 auditory dimensions of speech, namely the speaker's gender and spatial location. The degree of ...

There are two main common misconceptions: the first is that dyslexia’s chief characteristic is difficulty with reading. This is very often not the case. An adult with dyslexia may be slightly slow in reading but otherwise competent. The chief characteristics of dyslexia in adulthood are weaknesses in phonology, auditory short-term memory (working memory), and visual processing skills. These wea...
