The paper describes the use of an operant procedure to assess the speech perception of 11 young (7 to 35 months old) hearing impaired children and 11 normally hearing subjects. Subjects were presented with a repeating background stimulus and conditioned to turn their head on presentation of a contrasting syllable. The head-turning responses were…

Summarizing research activities from January 1982 to December 1982, this is the eighth annual report of research on speech perception, analysis and synthesis conducted in the Speech Research Laboratory of the Department of Psychology at Indiana University. The report includes extended manuscripts, short reports, progress reports, and information…

The cause of music consonance perception is not known, but consonance has been defined by both physical and perceptual characteristics. This study tested the extent of differences in interval perceptions and preferences in a non-musically trained group of adults. The independent variables of frequency range, condition of presentation, and harmonic…

Describes two experiments which investigated the importance of immediate memory in explaining the defects of children with specific learning disabilities. A group of such children and group of normal children were compared with respect to their performance on an immediate memory task involving the recognition of letter trigrams. (Author/CS)

This paper reports the development of a discrimination task to investigate the sensitivity of children aged 3-8 years to a range of timbral stimuli. The paper discusses the strengths and weaknesses of other research exploring timbral perception and explains how the findings from these studies shaped the methodological approach of this study.…

Following a review of the literature on responses of autistic persons to environmental stimulation, three experiments are detailed which examine the relationship between modality preference and rate of acquisition of a discrimination task. First, seven autistic children's preference for colored lights and/or simple tones was assessed in a sensory…

First and third grade children's ability to coordinate reading and listening was studied using a "mismatch detection" task. A total of 15 first grade children and 15 third grade children of average to below average reading ability read printed texts while listening to recordings of the same texts, in which extraneous spoken words were…

A teaching technique that leads to auditory conceptualization--the ability to determine the number and order of sounds embedded within syllables--shows promise of measurably improving the reading proficiency of children of all ability levels. Based on C. and P. Lindamood's published technique, "Auditory Discrimination in Depth," the…

THE ABILITY OF SECOND GRADERS TO PRODUCE TACHISTOSCOPICALLY PRESENTED LETTER SEQUENCES AND DISCRIMINATE AND VOCALLY REPRODUCE AUDITORILY PRESENTED WORDS WAS STUDIED IN THREE EXPERIMENTS. THE READING DISABILITY GROUP WAS FOUND TO BE SIGNIFICANTLY AND CONSISTENTLY INFERIOR TO THE CONTROL GROUP IN REPRODUCING THE VISUALLY PRESENTED LETTER SEQUENCES…

THE AUTHORS HAVE CONCERNED THEMSELVES IN THIS STUDY WITH IMITATION AS A DEVICE BY WHICH THE INVESTIGATOR CAN LEARN ABOUT CHILD LANGUAGE. THE DATA EXAMINED ARE PART OF A LONGITUDINAL THREE-MONTH STUDY OF LINGUISTIC DEVELOPMENT IN A TWO-YEAR-OLD CHILD. THE REPORT IS BASED ON 1,000 ELICITED IMITATIONS. CERTAIN PHENOMONA WERE OBSERVED GENERALLY WHEN…

The purpose of this investigation was to evaluate the effects of a systematic auditory training program on the auditory discrimination ability and reading readiness of 55 white, middle/upper middle class kindergarten students. Following pretesting with the "Wepman Auditory Discrimination Test,""The Clymer-Barrett Prereading Battery," and the…

An auditory discrimination procedure was used in this study to attempt to correct the speech problem of a 4-year-old girl. The major characteristic of that speech problem was the consistent use of inappropriate first consonant sounds in some words, like "gog" for "dog." The child was given 25 training sessions and two posttraining sessions. The…

It is the contention here that the "prelinguistic" period is an important phase of the language acquisition process. Accordingly the research reported represents an attempt to begin mapping out the types of linguistically relevant information to which a young child attends. Specifically it is hypothesized that young children are…
