Previous research shows that children with reading disorders perform poorly on auditory processing (AP) tasks. Correlational studies have also shown significant associations between some AP tasks and word and nonword reading. There is less clear evidence for AP contributions to spelling and passage reading. The aim of this research was to extend current knowledge by investigating the association between a range of AP measures used clinically and children's reading of words, nonwords, and passages, as well as word spelling.
Regression analyses were conducted on data from 90 children 7 to 13 years of age (58 males) with reported listening and/or reading concerns. All children had normal hearing sensitivity and were tested on AP tasks including the frequency pattern test (FPT), dichotic digits test, random gap detection test, and the masking level difference. Reading tasks included word, nonword, and passage reading. Phonologic processing, core language skills, nonverbal intelligence, memory, and attention were also measured.
All multiregression analyses were fixed order with age and gender, nonverbal intelligence, core language, phoneme manipulation, and digits backward scores included in the model before AP measures. FPT was the only AP task that accounted for significant unique variance in word/nonword reading and nonword spelling, but not passage reading.
The findings from this study failed to show an association between many clinically used AP measures and children's reading and spelling outcomes. Nevertheless, they reiterate the importance of evaluating FPT in children with word reading disorders. The findings justify further investigation into the role of this test when diagnosing children with reading or spelling disorders.
