In four experiments, evidence was found for a complex psychological representation of musical pitch. The perception of music depends not only on psychoacoustic properties of the tones, but also on processes that relate the tones to one another through contact with a well-defined and complex psychological representation of musical pitch.

Applied to the recognition of words in noise, the theory of the perceptual identification of complex stimuli provides a quantitative account of the proportions in which correct and erroneous responses of different frequencies will occur. (Author)

This study tested the hypothesis that there is a developmental shift in the perceptual weighting of acoustic parameters that results from experience with a native language. Comparison of 17 3-year olds and 16 adults found that age-related differences in auditory sensitivity did not fully account for age-related differences in perceptual weighting…

Perceptual discrimination between speech sounds belonging to different phoneme categories is better than that between sounds falling within the same category. This property, known as ''categorical perception,'' is weaker in children affected by dyslexia. Categorical perception develops from the predispositions of newborns for discriminating all…

N. F. Viemeister and G. H. Wakefield's (1991) multiple looks hypothesis is a theoretical approach from the psychoacoustic literature that has promise for bridging the gap between results from speech perception research and results from psychoacoustic research. This hypothesis accounts for sensory detection data and predicts that if the "looks" at…

Auditory pattern recognition skills in children with reading disorders were investigated using perceptual tests involving discrimination of frequency and duration tonal patterns. A behavioral test battery involving recognition of the pattern of presentation of tone triads was used in which individual components differed in either frequency or…

An auditory perception study investigated the ability of 104 Japanese university students, all learners of English as a second language, to distinguish between five English voiceless fricatives in nonsense syllables. Stimuli consisted of 75 tokens presented in consonant-vowel, vowel-consonant-vowel, and vowel-consonant syllables spoken within a…

Summarizing research activities in 1989, this is the fifteenth annual report of research on speech perception, analysis, synthesis, and recognition conducted in the Speech Research Laboratory of the Department of Psychology at Indiana University. The report contains the following 21 articles: "Perceptual Learning of Nonnative Speech…

THE RELATION OF HEARING LOSS IN SCHOOL PUPILS TO INFORMATION DERIVED FROM (1) SOCIOMETRIC TESTS, (2) SOCIAL BEHAVIOR TREND INDEXES, (3) TEACHER JUDGMENTS AND RATINGS, (4) PARENT QUESTIONNAIRES, AND (5) STANDARDIZED ACHIEVEMENT AND INTELLIGENCE TESTS WERE EXAMINED. THE SUBJECTS CONSISTED OF AN EXPERIMENTAL GROUP OF PUPILS WITH VARIOUS TYPES AND…

Just as the perceptual act of seeing and the higher cerebral process involved in reading are not identical, "listening" at the signal level of auditory perception is different from the act of auditory symbol comprehension known as "auding." Definitions of auding and contrasts between this process and the act of listening have been offered by Don…

The purpose of this study is to determine whether non-musically trained persons can make pitch discriminations as well as those with musical training. Four musically trained and four non-musically trained adults listened to an audio recording of pitches and judged whether the second pitch was higher or lower than the first. The results indicate…

This teacher's guide contains a list of general auditory problem areas where students have the following problems: (a) inability to find or identify source of sound; (b) difficulty in discriminating sounds of words and letters; (c) difficulty with reproducing pitch, rhythm, and melody; (d) difficulty in selecting important from unimportant sounds;…
