Describes a set of hands-on corridor demonstrations that illustrate various aspects of interference and diffraction of light waves and sound waves. (11 references) (JRH)

This study, involving five experienced and trained speech language pathologists, categorized the elicited imitations of five profoundly and five severely prelingually hearing-impaired subjects using the Phonetic Level Evaluation. Failure to obtain acceptably high levels of reliability suggests that this measure may not yet be an accurate and…

Tests experimentally whether stress placement in polysyllabic words differs in Singapore English (SE) and British English (BE), or whether acoustic correlates of stress differ in the two English varieties. Results suggest word-final stress in SE is not result of lexical stress placement, but combination of lengthening of final-syllable words in…

Describes how oral and written-discourse processes in a high school physics class are related to sociocultural practices in scientific communities. Finds that students' appropriation of scientific discourse was related to the framing activities of the teachers and the social practices established over time in the classroom. Contains 74 references.…

Measured the first two vowel-tract resonances of a sample of native-French speakers for the non-nasalized vowels of that language. Values measured for native speakers for a particular vowel were used as target parameters for subjects who used a visual display of an impedance spectrum of their own vocal tracts as real time feedback to realize the…

Describes a set-up for sending the infrared signal from a common remote control device to an oscilloscope in order to "see" the infrared signal. (WRM)

Contains information on rain sticks and other similar musical instruments. Describes procedures for making rain sticks and using them in the study of sound. Discusses the physics of sound and how to utilize computers to study sound with rain sticks. (DDR)

The article focuses on learning music among children. It is said that in general music, many concepts are introduced to young students. Most teachers have learned the mental health survival skill of teaching the appropriate use of an outdoor voice, an indoor voice, and a whisper voice. Tempo is much the same argument as volume. (Contains 2…

Despite intensive work on language-brain relations, and a fairly impressive accumulation of knowledge over the last several decades, there has been little progress in developing large-scale models of the functional anatomy of language that integrate neuropsychological, neuroimaging, and psycholinguistic data. Drawing on relatively recent…

We investigated learning-related changes in amplitude, scalp topography, and source localization of the mismatch negativity (MMN), a neurophysiological response correlated with auditory discrimination ability. Participants (n = 32) underwent two EEG recordings while they watched silent films and ignored auditory stimuli. Stimuli were a standard…

A possible role of the cerebellum in detecting and recognizing event sequences has been proposed. The present study sought to determine whether patients with cerebellar lesions are impaired in the acquisition and discrimination of sequences of sensory stimuli of different modalities. A group of 26 cerebellar patients and 26 controls matched for…

Understanding the function of the distinct amygdaloid nuclei in learning comprises a major challenge. In the two studies described herein, we used c-Fos immunolabeling to compare the engagement of various nuclei of the amygdala in appetitive and aversive instrumental training procedures. In the first experiment, rats that had already acquired a…

Some children have difficulty in perceiving differences between sounds, even though they have normal hearing sensitivity, and it has been suggested that such problems could lead to difficulties in language and literacy development. Poor ability to distinguish sounds on the basis of frequency (perceived as pitch) has been described in poor readers…

Occupational noise-induced hearing loss is the second most self-reported occupational illness or injury in the United States. Among coal miners, more than 90% of the population reports a hearing deficit by age 55. In this formative evaluation, focus groups were conducted with coal miners in Appalachia to ascertain whether miners perceive hearing…

This study investigated the efficacy of sound-field amplification (SFA) for improving the speed with which students with emotional and behavioral disorders (EBD) follow teacher directions. We used a multiple baseline design across six students in general education classrooms. Latency data were collected under nonamplified and amplified conditions…
