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…

Extended findings of a study that found that increasing the salience of perceptually important regions of nonsense word and sentence materials aids speech perception in noise by investigating the robustness of these enhancement techniques in improving consonant intelligibility for a range of different speakers and for groups of listeners with…

Describes the Verbal Transformation Effect (VTE): When listeners hear the same word repeated very many times at a rapid rate, the word tends to be perceived as other words. Reports lexical effects in the VTE and examines their cause. (Author/VWL)

This study examined event-related potentials (ERPs) to synthetic consonant-vowel syllables from 26 newborns with familial risk for dyslexia and 23 control infants participating in a longitudinal study of dyslexia. Results indicated that the cortical electric activation evoked by speech elements differed between children with and without risk for…

Musically tone-deaf individuals have psychophysical deficits in detecting pitch changes, yet their discrimination of intonation contours in speech appears to be normal. One hypothesis for this dissociation is that intonation contours use coarse pitch contrasts which exceed the pitch-change detection thresholds of tone-deaf individuals (Peretz &…

Most, if not all, of the studies of subtypes of children with language impairments have been conducted with English-speaking children. The possibility and validity of identified subtypes for non-English clinical populations are, as yet, unknown. This study was designed to provide cross-linguistic evidence of language subtypes. A broad battery of…

What do musicians, critics, and listeners mean when they use emotion-words to describe a piece of instrumental music? How can "pure" musical sounds "express" emotions such as joyfulness, sadness, anguish, optimism, and anger? Sounds are not living organisms; sounds cannot feel emotions. Yet many people around the world believe they hear emotions…

Over the past couple of decades, research has established that infants are sensitive to the predominant stress pattern of their native language. However, the degree to which the stress pattern shapes infants' language development has yet to be fully determined. Whether stress is merely a cue to help organize the patterns of speech or whether it is…

This study investigated multisensory interactions in the perception of auditory and visual motion. When auditory and visual apparent motion streams are presented concurrently in opposite directions, participants often fail to discriminate the direction of motion of the auditory stream, whereas perception of the visual stream is unaffected by the…

In 3 experiments, the authors tested performance in simple tone matching and classification tasks. Each tone was defined on location and frequency dimensions. In the first 2 experiments, participants completed a same-different matching task on the basis of one of these dimensions while attempting to ignore irrelevant variation in the other…
