This study examined the abilities of 18 adults with familial dyslexia to use steady state, dynamic, and temporal cues in synthetic speech continua. Although subjects were able to label and discriminate the continua, they did not necessarily use acoustic cues in the same manner as did normal readers, and their overall performance was less accurate.…

The ability to recall correctly ordered information was examined using two auditory tasks (narrative recall and digit span) and a nonverbal, visual task, with 47 individuals with Down's syndrome (ages 5 to 20) and 47 mentally aged-matched children. Although Down's syndrome subjects recalled less information than controls, no differences in the…

Ten children (ages 5-6) and 10 adults participated in discrimination and selective adaptation speech perception tasks using a synthetic consonant-vowel continuum. Results support hypotheses of sensory processing differences in younger, normally developing children compared with adults and show that such abilities appear to be related to speech…

Describes several ways to demonstrate the relationship between various aspects of auditory stimulation and sensation. Discusses the equipment required to hear and to visualize simultaneously a variety of auditory signals. States that these demonstrations allow students to learn more about sensory processing in general and auditory function in…

Discusses how the visual system operates as an avenue for learning through the intermeshing of its three systems: sensory, motor, and central processing. States that the evaluation of all three systems is vital to the diagnosis of and prescription for poor readers. (MG)

Hearing in Noise Test (HINT) list equivalency was examined using 24 listeners (ages 60 to 70) with sensorineural hearing impairments. Four speech conditions were tested, including a quiet condition and three noise conditions. Results found that for the three noise conditions, all lists were within 2dB of the means, indicating list equivalency.…

Children (N=110, ages 8 to 10) with either normal or poor reading ability were tested on (1) ability to recall sequences of nonspeech tones presented at various rates, and (2) ability to make phonetic decisions using brief and transitional properties of the speech signal. Results did not support the hypothesis that temporal-processing deficits…

Attempts to determine the relative difficulty of playing selected types of melodic pattern by ear; studies the effects of performance experience and instrument family on the ability to play by ear; and investigates the relationship between tonal aptitude and ability to play by ear. Presents results and questions for further research. (DSK)

Investigates effects of variations in tone quality on listeners' perception of both tone quality and intonation. Indicates that more inexperienced instrumentalists rated stimuli that were "brighter" in quality as sharper in intonation, and those that were "darker" as flatter. Also, finds differences for brass versus woodwind instruments. (DSK)

This study compiled a comprehensive early auditory processing skills assessment battery and evaluated the battery to toddlers with (n=8) and without (n=9) early recurrent otitis media. The assessment battery successfully distinguished between normal and deficient early auditory processing development in the subjects. The study also found parents…

Studied whether patterns of developmental progression in reality monitoring were present in visual and auditory modalities and the role of cross-modal imagery in reality-monitoring tasks. Found scores revealed evidence of developmental progression in both auditory and visual source-monitoring tasks, but no effect of cross-modal imagery. (Author)

When presented with stimuli that contain illegal consonant clusters, Japanese listeners tend to hear an illusory vowel that makes their perception conform to the phonotactics of the language. Assesses an alternate hypothesis that this illusion is due to a top-down lexical effect. (Author/VWL)

Assessed development of infants' sensitivity to two nested amodal temporal relations in audible and visible events. Found that sensitivity to synchrony was present by 4 weeks, remaining stable across age. Sensitivity to composition emerged by 7 weeks, increasing dramatically with age. Noted pattern of increasing specificity in perception…

Examined two aspects of the specificity of practice hypothesis using a tracking task. In one experiment, visual or auditory feedback about performance was provided. In a second experiment, visual and auditory information were combined. Both experiments supported the specificity of practice hypothesis. Instructing participants to attend to one…

A double-blind, placebo-controlled study examined effects of methylphenidate (Ritalin) on auditory processing in 32 children with both attention deficit hyperactivity disorder and central auditory processing (CAP) disorder. Analyses revealed that Ritalin did not have a significant effect on any of the central auditory processing measures, although…
