Investigates psychophysiological reactions of 60 women to an infant's cry and to a control sound. The 30-second pain cry evoked greater cardiac and electrodermal activity than did the control stimulus, although selected groups varied in the nature and extent of their reactions. Both maternal state and experience with infants affected reactions.…

Three observers evaluated the responses to sound with 21 mild to severely handicapped children (7 months to 10 years old) on Behavioural Observation Audiometry, an alternative to conditioning paradigms in audiometric assessment. Results showed that inter-observer agreement was high and that responsitivity was not affected by stimulus presentation…

Deaf subjects required about 9 dB greater speech-to-noise ratio for 75 percent correct detection of words than did normal-hearing subjects, suggesting that maximum communication effectiveness may occur for hearing impaired children only at higher speech-to-noise ratios than that required by normal-hearing persons.

A series of investigations were conducted to determine whether reflexive crying occurs in newborns and to define the parameters that control his behavior. (NH)

Using auditory ensembles of sound that differed in frequency, intensity, and duration, it was found that fifth graders more easily learn stimuli that are unlike speech than those which closely approximate speech. (MH)

This study was undertaken to determine whether context independence (the degree to which the phonetic categorization of a given stimulus is independent of the context in which it occurs) and phonetic mediation (the degree to which discrimination appears to be based on category labels) are independent aspects of categorical perception. (Author/LC)

The experiment investigated the possibility that autistic adolescents may avoid speech communication with the world around them by "tuning out" or perceptually suppressing auditory speech stimuli. The tune out auditory suppression hypothesis was investigated using the S's own speech as the stimulus under three perceptual-motor conditions. (Author)

Relationships among tone height, melodic contour, tone chroma, and recognition of recently learned melodies were investigated. Results replicated previous studies using familiar folk songs, providing evidence that melodic contour, tone chroma, and tone height contribute to recognition of both highly familiar and recently learned melodies.…

Research demonstrated successful discrimination in twenty 6-week-old infants when cardiac rate responses were employed in a no-delay rather than in the conventional discrete trials paradigm. (Author/SB)

Three experiments were undertaken involving three users of multi-electrode cochlear prostheses. The experiments established a scale of stimulus loudness; measured minimum-detectable gaps for sinusoidal stimuli as functions of stimulus level, frequency, and electrode place within the cochlea; and assessed independence of the electrodes using a…
