Pitch constancy, perceiving the same pitch from tones with differing spectral shapes, requires one to extract the fundamental frequency from two sets of harmonics and compare them. We previously showed this difficult task to be easier when tonal context is present, presumably because the context creates a tonal reference point from which to judge…

Recent work on perceptual learning shows that listeners' phonemic representations dynamically adjust to reflect the speech they hear (Norris, McQueen, & Cutler, 2003). We investigate how the perceptual system makes such adjustments, and what (if anything) causes the representations to return to their pre-perceptual learning settings. Listeners are…

An instrument for measuring and tracking changes in auditory skill development over time was developed for use with a group of children with profound deafness who received a MED-EL COMBI 40+ cochlear implant. The aim of this paper is to describe the use of this instrument, the "Checklist of Auditory Communication Skills", and to present results…

Changes in selection criteria have meant that children are being provided with cochlear implants (CI) at increasingly younger ages. However, there is a paucity of measures that are appropriate for testing complex listening skills--most tests are too cognitively complex for such young children. The Common Objects Token (COT) Test was developed as a…

Twenty-five newborn infants were tested for auditory-oral matching behavior when presented with the consonant sound /m/ and the vowel sound /a/--a precursor behavior to vocal imitation. Auditory-oral matching behavior by the infant was operationally defined as showing the mouth movement appropriate for producing the model sound just heard (mouth…

Auditory perception of English minimal pairs was tested with or without noise background. Each subject was interviewed after the test to collect information regarding their early experience on learning English as a foreign language. This study was designed to examine the differential effects of learning English at three age-starting points and two…

The role of central auditory processing in reading skill development and reading disorders is unclear. The purpose of this study was to examine whether individuals with specific reading disabilities (SRD) have deficits in processing rapidly presented, serially ordered non-speech auditory signals. To this end, we compared 12 children with SRD and…

This study examined the roles of speech perception and phonological processing in reading and spelling acquisition for native and nonnative speakers of English in the 1st grade. The performance of 50 children (23 native English speakers and 27 native Korean speakers) was examined on tasks assessing reading and spelling, phonological processing,…

Auditory and auditory-visual (AV) speech perception skills were examined in adults with and without language-learning disabilities (LLD). The AV stimuli consisted of congruent consonant-vowel syllables (auditory and visual syllables matched in terms of syllable being produced) and incongruent McGurk syllables (auditory syllable differed from…

To test the hypothesis that level of neural complexity explain the relative level of performance and brain activity in autistic individuals, available behavioural, ERP and imaging findings related to the perception of increasingly complex auditory material under various processing tasks in autism were reviewed. Tasks involving simple material…

This study determined whether listeners with hearing loss received reduced benefits due to an onset asynchrony between sounds. Seven normal-hearing listeners and 7 listeners with hearing impairment (HI) were presented with 2 synthetic, steady-state vowels. One vowel (the late-arriving vowel) was 250 ms in duration, and the other (the…

This study evaluated the validity of using an earplug so that information is presented to only one ear of children (N=34) in Alberta, Canada, with learning disabilities as a means of improving listening comprehension. Children were asked to recall stories from the Auditory Comprehension Test (ACT) immediately after hearing the story. The children…

The paper examines ways in which language complexity of the stimulus and language ability of the receivers may influence learning via television for hearing impaired and hearing children. Research is reviewed on the impact of language abstraction on learning from television, and findings from paired associate learning trials are cited to suggest…

Describes the musical sounds which can be found in unexpected places, and presents classroom projects which will enable heretofore visually oriented students and teachers to rediscover their ears. (BD)

The article deals with various interference factors affecting aural perception and articulation, such as: similarity of the foreign sound to the native sound, different combinations, differences of articulation, significance of correct perception of sounds, etc. (Text is in German.) (IFS/WGA)
