Analyzes a method of detecting changes in a particular frequency band by evaluating the overall shape or profile of the auditory signal spectrum. Claims that profile analysis is different from intensity discrimination, and applies the new method to detecting noise sinusoid and to results obtained when signal frequency is uncertain. (Author/AOS)

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…

Focuses on the relationship between loudness and intensity of sounds. (Author/PVD)

Focuses on the concepts of pitch and timbre of sounds. (PVD)

To better identify the auditory strengths of elementary school children, a test was developed using a pure tone approach with sets of signals. (SBH)

The application of electrophysiologic measurement techniques in the study of mental retardation, autism, and other disorders previously considered "behavioral" or "psychological" is discussed. (Author)

This issue of a newsletter for second language researchers and teachers features an article by Michael Clyne entitled "Research on Bilingual and Second Language Acquisition in Australia." The article provides abstracts of Australian research projects in English as a second language, perception of Australian English speech, testing second…
