Investigates preperceptual auditory storage among eight 9-week-old infants in three experiments using a modification of an adult masking paradigm and a nonnutritive sucking discrimination procedure. Results suggest that echoic storage contributes to auditory perception in infancy and, for infants compared to adults, echoic traces have a longer…

Twenty hyperactive children (ages 6-16) were administered dichotic digits tasks requiring free report and selective listening under stimulant medication (methylphenidate). Results demonstrated that stimulants may act to maintain selective attention and to inhibit channel switching. Right-ear superiority was influenced by task variables but not by…

When equated on level of maturity, preterm infants were indistinguishable from full-term infants in their rates of response decrement to stimulus repetition and their subsequent response to a novel stimulus. Responsiveness to auditory novelty at four months was a strong predictor of 18-month mental performance for females but not for males. (RH)

Three hundred children (ages 5 to 12) were required to discriminate simple, familiar, monosyllabic words under two conditions: quiet and in the presence of background classroom noise. Of the sample, 45.3 percent made errors in speech discrimination in the presence of background classroom noise. The effect was most marked in children younger than 7…

Contrary to previous research, it was found that tests of auditory discrimination were not likely to differentiate between learning disabled children and nonlearning disabled children unless both groups were also articulatory defective. (Author)

The author refutes the conclusions of S. Finnegan's paper (see EJ 223 666) on the relationship between reading ability and auditory discrimination. (Author/PHR)

The results indicated that normal children experience auditory fusion at shorter time intervals than is true for either of the disabled groups, that signal intensity affects auditory fusion for all groups, and that only the learning disabled children are differentially affected by the frequency of the stimulus tones. (Author/PHR)

The study examined whether children with normal linguistic skills demonstrate increasing developmental changes in their perception of place of articulation for stop consonants with short- and long-duration formant transitions. Children's improving discrimination abilities did not reach adult levels even at 10 years of age. (Author/DB)

Examines the terms "phonemic segmentation" and "phonemic awareness," noting that these areas go beyond older notions of readiness and auditory discrimination. Claims that research in phonemic awareness has important instructional implications. (MM)

Eighty normally hearing children (ages 4 to 8) judged the clarity of sentences that were systematically bandpass-filtered to increase intelligibility. Study of 10 subjects at each age found that children 5 years or older were able to make reliable clarity judgements using paired comparisons or category rating; however, the method of paired…

This study examined identification and discrimination of initial bilabial stop consonants differing in voicing by 10 9-year-old children with a history of severe otitis media with effusion (OME). Long-term effects of OME were found for both identification and discrimination performance. In cases of language impairment with early OME, no additional…

Patients with unilateral (left or right) medial temporal lobe lesions and normal control (NC) volunteers participated in two experiments, both using a duration bisection procedure. Experiment 1 assessed discrimination of auditory and visual signal durations ranging from 2 to 8 s, in the same test session. Patients and NC participants judged…

We investigated how different psychophysical procedures affect frequency discrimination performance in children. Four studies used a design in which listeners heard two tone pairs and had to identify whether the first or second pair contained a higher frequency target tone. Thresholds for 6-and 7-year-olds were higher than those for 8- and…

Standard diagnostic procedures for assessing temporal-processing abilities of adult patients with aphasia have so far not been developed. In our study, temporal-order measurements were conducted using two different experimental procedures to identify a suitable measure for clinical studies. Additionally, phoneme-discrimination abilities were…

Representational momentum refers to the phenomenon that observers tend to incorrectly remember an event undergoing real or implied motion as shifted beyond its actual final position. This has been demonstrated in both visual and auditory domains. In 5 pitch discrimination experiments, listeners heard tone sequences that implied either linear,…
