Thirty-six visual and auditory tests were given to 113 fifth and sixth grade students. Second-order analysis yielded two well-defined factors representing Fluid and Crystallized Intelligence and two perceptual factors corresponding to General Visualization and General Auditory Function. Perceptual factors were not clearly separated from broad…

A comparative study of nonverbal MA matched groups of five autistic, five aphasic, five normal and five retarded children (3 to 16 years old) was made on an auditory-visual and a visual-visual paired-associate learning task. (Author)

Central auditory function was assessed in 10 stutterers and 10 nonstutterers between the ages of 10 and 35 years, and the performance of the two groups compared for seven audiometric procedures, including acoustic reflex threshold and acoustic reflex amplitude function. (Author)

Teaching and learning can take place only when teacher and pupil understand and share beliefs in the basic concepts of what is being communicated. (JD)

A review of research on the three types of auditory disorders, concentrating on inefficient learning which results from problems in auditory processing. (DD)

The selective tuning of feature detectors sensitive to the acoustic information relevant to the assignment of distinctive phonetic feature values was investigated with a contingent adaptation paradigm. (Author/RM)

Twelve children (4 1/2 to 8 1/2 years old) with normal language development, 12 normal adults, and 12 dysphasic children (6 to 9 years old) were tested for their ability to perceive binary sequences of nonverbal auditory stimuli. (Author/SBH)

Eighteen moderately mentally retarded adults, 20 nonretarded elementary age children, and 20 nonretarded adults were exposed to three conditions of an auditory detection task (location, meaning, and a combination of both). Developmentally immature subjects (retarded adults and nonretarded children) demonstrated less efficient attentional capacity.…

Evaluates the discrimination of signal and silence duration in six-month-old infants, children aged 5 1/2 years, and adults. Results show that infants discriminated duration changes of 20 milliseconds or greater, children discriminated 15 milliseconds, and adults as few as 10 ms. Findings are consistent with other research in revealing age-related…

Thirty learning disabled elementary grade students were given the Flowers Auditory Test of Selective Attention and the Goldman Fristoe Woodcock Auditory Selective Attention Test. Weak but significant correlations between the two tests of auditory selective attention suggested that the tests do not measure exactly the same constructs. (Author/DB)

Reports on three experiments that investigated why young children's perceptions of bimodal speech are less influenced by the visual component of speech than adults' perceptions are. Results argue in favor of the explanation that children are poorer lipreaders than adults. (HOD)

Discusses (1) the process of early language development, giving specific attention to problematic aspects of a vocabulary for audition; (2) elicitation and instruction tasks used in the study of language acquisition; and (3) an investigation designed to compare language acquisition for dimensions of visual, spatial, and tactual perception with…

Reports a study of the ability of Black children to hear final consonant blends even though they may not or cannot pronounce them. (TO)

The primary purpose of this study was to determine the size of the sound stimulus employed in the first stage of speech recognition. (Author)
