Examines the hypothesis that early auditory temporal processing deficits cause later specific reading disability by impairing phonological processing. Suggests that auditory temporal deficits in dyslexics may be associated with dysphasic-type symptoms observed by Tallal and her colleagues in specific language-impaired populations, but do not cause…

Studies evaluating temporal auditory processing among individuals with reading and other language deficits have yielded inconsistent findings due to methodological problems (Studdert-Kennedy & Mody, 1995) and sample differences. In the current study, seven auditory masking thresholds were measured in fifty-two 7- to 10-year-old children (26…

The speech procedure, utilizing an attractive mechanical device in the form of a clown, proved to be effective and efficient for use with retarded children. (Author)

A forward-gating procedure employing familiar monosyllabic words was used in auditory testing of age- and gender-matched elementary students with and without learning disabilities. Results indicate auditory closure skills were comparable between disabled and nondisabled subjects, but sensory discrimination problems may contribute significantly to…

Simultaneous recordings of auditory brainstem and middle latency responses were obtained in both vertex-ipsilateral and vertex-contralateral derivations in 22 children, ages 8-12. For specific recording conditions, the latencies of middle latency responses differ significantly between children with and without learning disabilities, offering…

This paper presents results of 2 experiments examining effects of signal and masker uncertainty on 17 preschoolers' and 13 adults' detection of tonal signals in noise maskers. Effects of masker uncertainty significantly exceeded those of signal uncertainty. For most adults and some children, distracters produced higher thresholds and shallower…

Results of applying the electrophysiological measure of auditory long latency event-related potentials (P3 AERP) on 20 children with central auditory processing disorders before and after a structured treatment program found a significant decrease in P3 latency and a significant increase in P3 amplitude when compared with control subjects who had…

Sensitivity and specificity of static acoustic admittance (SAA) and tympanometric width (TW) were assessed for 116 pediatric patients. A statistically significant change in SAA was observed in immediate repeat measures. No significant change across the two sequential measures was observed for TW, peak pressure, or the estimate of ear canal volume.…

Puretone auditory assessment of 21 adults with severe to profound mental retardation indicated that a bivariate plotting procedure of predicting hearing sensitivity from the acoustic reflexes should be included in an audiological test battery for this population. (CL)

Psychometric functions (PFD) for the detection of pure tones were obtained from 10 adolescent and young adult listeners with normal hearing and 10 adult listeners with sensorineural impairments of presumed cochlear origin. The slopes of the PFDs were abnormally steep in some of the hearing-impaired listeners but were statistically significant only…

The speech of four phonologically disordered children (ages four and five) with place and voice errors affecting initial stop consonants was described through phonological and acoustic analyses. The presence of productive phonological knowledge, as inferred from acoustic data, facilitated rapid generalization of correct production of the treated…

Long-term effects on auditory electrophysiology from early fluctuating hearing loss were studied in 27 children, aged 5 to 7 years, who had been evaluated originally in infancy. Findings suggested that early fluctuating hearing loss disrupts later auditory brain stem electrophysiology. (Author/DB)

The observed listening performances of 64 children (ages 7-11) with central auditory processing (CAP) disorders were evaluated. Data indicated wide variations in listening performance depending upon the listening conditions and listening functions being rated. Findings suggested that these children had difficulties in both stressful and ideal…

This study evaluated the ability of 30 normally developing children (ages 6-12) to report the perceived location of a stationary fused auditory image (FAI) or track a "moving" FAI. Although subjects performed at normal adult levels with the stationary sound measure, they exhibited a significant age-related trend with the moving sound…

This study evaluated whether listeners can distinguish human brainstem auditory evoked responses elicited by acoustic clicks from control waveforms obtained with no acoustic stimulus when the waveforms are presented auditorily. Detection performance for stimuli presented visually was slightly, but consistently, superior to that which occurred for…
