Age‐related improvements in auditory temporal resolution in reading‐impaired children

Abstract

Individuals with developmental dyslexia show impairments in processing that require precise timing of sensory events. Here, we show that in a test of auditory temporal acuity (a gap-detection task) children ages 6-9 years with dyslexia exhibited a significant deficit relative to age-matched controls. In contrast, this deficit was not observed in groups of older reading-impaired individuals (ages 10-11 years; 12-13 years) or in adults (ages 23-25 years). It appears, therefore, that early temporal resolution deficits in those with reading impairments may significantly ameliorate over time. However, the occurrence of an early deficit in temporal acuity may be antecedent to other language-related perceptual problems (particularly those related to phonological processing) that persist after the primary deficit has resolved. This result suggests that if remedial interventions targeted at temporal resolution deficits are to be effective, the early detection of the deficit and early application of the remedial programme is especially critical.

The contribution of rapid visual and auditory processing to the reading of irregular words and pseudowords presented singly and in contiguity

“…They also display higher fusion points to separate two auditory temporal stimuli (Hari & Kiesilä, 1996;Hautus, Setchell, Waldie, & Kirk, 2003;McCroskey & Kidder, 1980). Poor readers take longer or make more errors when judging the order of two auditory stimuli presented in rapid succession (Heiervang, Stevenson, & Hugdahl, 2002;Mody, Studdert-Kennedy, & Brady, 1997).…”

Teorias da Dislexia: Sustentação com Base nas Alterações Perceptuais Auditivas

“…Longitudinal studies showed that the differences between the performance of dyslexic individuals and typical readers in tests evaluating auditory processing reduce as participants' ages advance. Hautus, Setchell, Waldie and Kirk (2003) have compared the performance of dyslexic individuals and typical readers of different age groups, in a task of detecting brief intervals of silence to evaluate the auditory temporal resolution skill. The authors found a significant difference in temporal resolution between the 6 to 9 age group.…”

It Is Time to Rethink Central Auditory Processing Disorder Protocols for School-Aged Children

“…B. U. Watson and Miller (1993) noted that reduced performance on challenging psychophysical tasks could be an indicator that cognitive deficits are present (Hautus, Setchell, Waldie, & Kirk, 2003;Zaidan & Baran, 2013). The British Society of Audiology (BSA, 2011a), in its position statement on auditory processing disorders, concluded that auditory processing disorder is "closely associated with impaired top-down, cognitive function" and that there is "no evidence that it is produced by a primary, sensory disability" (p. 6).…”
