This study investigated the construct validity of five perceptual traits (auditory discrimination, visual discrimination, visual memory, visual-motor coordination, and auditory to visual-motor coordination) with five simulated work samples (union assembly, resistor reading, budgette assembly, lock assembly, and nail and screw sort) from the Jewish…

This experiment was designed to better understand the effects of individual differences, intent to learn, and stimulus familiarity on frequency judgment accuracy. Half of the participants in the study heard popular songs, and the other half listened to unfamiliar songs. Participants were subdivided into three more groups, introducing the "intent…

University students were the subjects of three experiments designed to determine the usefulness of elliptic speech in investigating the perception of the phonological structure of continuous speech. Five naturally spoken and five synthesized paragraphs were recorded in two different randomizations of phonological distortions and at two different…

Discusses difficulties in perception of English /r/ and /l/ and concludes the error pattern is not predictable on the basis of contrastive phonological analysis but might be the result of acoustic-phonetic factors. (EKN)

Evaluation of 54 mentally retarded pupils, aged 10 to 13, in 1979 and comparison with six samples of mentally normal pupils collected during the last two decades confirm that prevalence of additional problems among mentally retarded pupils is greater as compared to mentally normal pupils with respect to nine variables. (NEC)

Elementary school students demonstrated a developmental trend in ability to judge speed solely on auditory cues. Second graders considered intensity cues relevant, and were most accurate on intensity shifts. Accuracy on frequency shifts increased across grades. Awareness of frequency and frequency-intensity relationships increased with age.…

Based on a sample of 95 first- and second-grade children with a Spanish language orientation (SPLO), psychometric information is provided for a newly constructed auditory perception test designed for children who are attempting to acquire basic reading, writing, and oral skills in standard American English.

Investigates the effects of morphological boundaries and the voicing characteristics of the following consonant on the duration of stressed vowels produced by hearing impaired adults. They do not vary the duration of stressed vowels in accordance with the durational recording observed in normal speech; however, this deviance is systematic. (PMJ)

After a review of the literature on learning a second-language sound system, a study is reported that used only perceptual training to improve both pronunciation and perception of /r/ and /l/ among 39 Japanese university students of English. Results suggest that listening practice can improve pronunciation and perception. (Contains 32 references.)…

Twenty reading-disabled, 10 math-disabled, and 25 control-group college students were assessed on a battery of psychophysical tasks that included 5 tests of temporal processing. Findings suggest that poor temporal processing is neither a necessary nor a sufficient cause of reading disability but that there is a modest association between the two…

This study of visual and auditory problems in 17 children (ages 7-10) with dyslexia concluded that, although eye tracking and binocular fusion problems should always be considered in the assessment of dyslexics, factors involved in information processing in auditory and visual perception appear to be more highly implicated. (Author/JDD)

A study evaluated the use of a clinical tool developed to determine the listening behavior of young children at risk for developmental communication delays. The evaluation procedure was developed and successfully applied to 66 children (ages birth to 3) attending an early intervention program over a period of 3 years. (Contains six references.)…

Infants parse speech into word-sized units according to biases that develop in the first year. One bias, present before the age of 7 months, is to cluster syllables that tend to co-occur. The present computational research demonstrates that this statistical clustering bias could lead to the extraction of speech sequences that are actual words,…

Purpose: The purpose of this study was to examine the longitudinal predictive relationships among variables that may contribute to poor phonological awareness skills in preschool-age children with speech-sound disorders. Method: Forty-seven children with speech-sound disorders were assessed during the spring of their prekindergarten year and again…

Purpose: The purpose of this study was to determine whether memory support and elicited production differentially benefited fast mapping of new vocabulary (comprehension, production accuracy, and speed) in adolescents with Down syndrome (DS) compared with typically developing (TD) children matched for syntax comprehension. The study also examined…
