Central auditory processing disorders in the elderly: the effects of pure tone average and maximum word recognition

We previously examined central auditory processing disorders and the effect of age in 1026 64- to 93-yr-olds. Here, we correlated three indices of central auditory processing disorders with age, pure tone averages (PTA) and maximum word recognition scores. With one exception, correlations of indices with PTA equaled or exceeded those with age. With one exception, correlations with word recognition scores were insignificant or smaller than those with age. Although statistically significant, the magnitudes of most effects were small (0.003 less than r2 less than 0.146). However, PTA accounted for approximately 30% of the variability in corrected Staggered Spondaic Word test error scores.
