Discusses a study comparing children's perception of temporal acoustic cues to that of adults. Subjects were asked to identify voiced or voiced CVC words with uniformly voiceless final obstruents but in which vowel duration was systematically varied. Results show that subject age and vowel duration of test stimuli affect identification processes.…

Notes that the ability to analyze the media is linked directly to the way that images are projected and to the channels through which they are received. Contends that a story heard affects a person differently than does a story seen. (FL)

Twenty-four children (ages 6-10) with language impairment (LI) and 22 without participated in a study of discrimination, identification, and serial ordering of highly dissimilar and similar vowels. Children with LI were less accurate in several tasks and were found to experience auditory perception deficits which led to less robust central…

Infants looked at visual displays of two or three items while listening to auditory sequences of two or three sounds. When the rate and duration of sounds were constant, infants looked longer at the visual display that was numerically equivalent to the auditory sequence. When the rate and duration of sounds varied, infants showed no preference for…

Investigated the feasibility of adding haptic and auditory displays to traditional visual geographic information systems (GISs). Explored differences in user performance, including task completion time and accuracy, and user satisfaction with a multimodal GIS which was implemented with a haptic display, auditory display, and combined display.…

Examined the processing of potential auditory and visual cues that differentiate statements from echoic questions. Found that both auditory and visual cues reliably conveyed statement and question intonation, were successfully synthesized, and generalized to other utterances. (Author/VWL)

Comparison of the lexical characteristics of 88 auditory misperceptions showed no difference in word-frequency, neighborhood density, and neighborhood frequency between the actual and the perceived utterances. Another comparison showed that slip of the ear tokens had denser neighborhoods and higher neighborhood frequency than words in general.…

Effects of variation from stimulus to stimulus in emotional tone of voice on speech perception were examined through a series of perceptual experiments. Stimuli were recorded from human speakers who produced utterances in tones of voice designed to convey affective information. Stimuli varying in talker voice and emotional the where then presented…

This commentary on EC 232 373 and EC 232 374 suggests that a theory that depends on categorizing events as either stuttering or nonstuttering must fail. It evaluates the merit of the voluntary/involuntary distinction in loss of speech production control, defends research on the nature of stuttering, and proposes additional research and theory.…

The study comparing perceptual judgments of speech disfluency by 20 mothers of either stuttering or normally fluent children found no appreciable differences between groups in their judgments. Both groups of mothers most frequently judged sound/syllable repetitions to be stuttered, followed by whole-word repetitions and broken words. (Author/DB)

Comparison of the auditory frequency resolving ability of preschool children, school-aged children, and adults found data from children as young as three-years-old that were qualitatively indistinguishable from adult data though threshold estimates from young children were more variable from run to run than from adults. Increasing age improved…

Assessed auditory temporal acuity among infants of 3, 6, and 12 months of age and adults. Gap detection thresholds were quite poor in infants. Effects of restricting the range of frequencies available for detecting gaps were qualitatively similar for infants and adults. (GLR)

This study found correlations (.45 to .59) between scores on a battery of auditory discrimination tasks and measures of intelligence and academic aptitude in two samples of college students. An implication is that intelligence is a potential confounding variable in studies of the auditory perceptual abilities of various clinical populations.…

This investigation examined the response strategies and discrimination accuracy of adults and children (aged 5-10) as the ratio of same to different trials was varied across 3 conditions of an auditory discrimination task. All subjects changed response strategies depending on the ratio of same-to-different trials. (DB)

Two experiments investigated lateral asymmetries in eight-month-olds' perception of contour-altered and contour-preserved melody changes. Found that infants who heard a contour-altered change showed a left-ear advantage, whereas infants who heard a contour-preserved change showed a right-ear advantage. The pattern of lateralization for melody…
