Development of the ability to classify auditory patterns was studied at grades 2, 6, 10, and 12 and at adult age levels. Both accuracy and feature use in classification were consistent across age; the age changes that did occur appeared to be due to differences in perception rather than process. (JMB)

This article describes an experiment in which the following hypothesis was tested and supported: that tension serves to reinforce the phoneme's articulatory characteristic, whether it be closure or openness; and that audibility interferes with perception of tension. (Text is in French.) (AM)

This article presents a sensory description of the sounds of language which differs from the traditional acoustic or articulatory description. The main idea is that sounds differ according to auditory and extra-auditory factors. (Text is in French.) (AM)

Research is reported in which subjects were required to perceive sentences in noise. A series of sentences having the same syntax and rhythm was presented. On a final sentence either rhythm alone or rhythm plus syntax were changed. The results stress the importance of rhythm in speech perception. (Author/RM)

One of a series of semiannual reports, this publication contains 12 articles which report the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical applications. The titles of the articles and their authors are as follows: "Coarticulatory Organization for Lip-rounding in Turkish and…

Designed to help children with auditory perceptual problems from fourth through sixth grade, the manual contains essays and exercises to develop listening skills, auditory memory, vocabulary, and imagination. The first section contains instructions to the teacher and the essays which are at three levels of difficulty and intended to be read to the…

In an investigation using auditory evoked responses (AERs) to compare strongly left- and strongly right-handed adults in their hemispheric processing of speech materials, it was anticipated that AERs would reflect a bilateralization in the left-handed group of subjects and marked hemispheric differences in the right-handed group. In addition, the…

Earlier research (Thorson, et al., 1976) found that latencies increase for acoustically confusable letter pairs and decrease for visually confusable letter pairs as a positive function of interstimulus interval (ISI). To extend these findings to different age groups, 30 young adults (mean age, 21.4 years) and 30 older adults (mean age, 68.8 years)…

Nineteenth- and twentieth-century models of first and second language reading are examined and compared. Figures are provided of six models that propose relationships among visual input and processes, auditory input, phonological processes, and comprehension. These models illustrate the processes that may be operating in persons who achieve their…

Compared on subtests of the Parramatta Test of Developmental Levels for Infant Grades were scores of 150 grade 1 children who had a maximum of five school terms with the Z. Kodaly music program (group K) and scores of 541 previously tested grade 1 children (sample group). (MC)

Assessed were the abilities of 50 normal 5-to 9-year-old children and 30 learning disabled 7-to 9-year-old children to recognize temporal patterns presented visually and auditorially (intramodal abilities) and to vocally produce the patterns whether presentation was visual or auditory (intramodal and cross-modal abilities).
