Infants' use of auditory information in guiding their search behavior is examined in this study. The subjects were two groups of 9-month-old crawling infants. Group 1 consisted of 24 infants and Group 2 of 16 infants. The auditory stimuli was the mother's voice. Infants in both groups were initially positioned by their mothers behind a screen in a…

Twenty normal newborns, approximately 36 hours old, were tested using an auditory temporal conditioning paradigm which consisted of a slow rise, 75 db tone played for five seconds every 25 seconds, ten times. Responses to the tones were measured by instantaneous, beat-to-beat heartrate; and the test trial was designated as the 2 1/2-second period…

Described are clinical techniques and procedures useful in evaluations for exaggerated hearing levels. Discussed are considerations of the audiologist, his equipment, and erroneous findings; patient cooperation, anticipated hearing handicaps, detection of exaggeration, and order of test presentation; voluntary aid conduction audiometry,…

The intriguing possibility has emerged that the mechanisms processing information concerning different attributes might arrive at incompatible conclusions, so that stimuli are perceived which have paradoxical properties. This study demonstrated just such a situation. (Author/RK)

Studied the utility of cardiac habituation/response recovery as a measure for assessing infant cerebral asymmetries in auditory perception on a dichotic listening test. (Author/SB)

The differential effects of normal and emphatic stress on the auditory comprehension performance of nine aphasic and five normal adults were assessed. The aphasic subjects demonstrated significantly better performance for stimuli presented with emphatic stress. (Author/DB)

Examines the relation between aspects of the fundamental frequency (basic pitch) of 16 infant newborn cries and 28 multiparous mothers' perceptions of those cries. Results support the hypothesis that increases in fundamental frequency are related to increases in maternal perceptions of the intensity of the infant's cry. (Author/RWB)

Study measures the precision of auditory localization in 26- to 30-week-old infants using the adult minimum audible angle test. Results show that infants discriminate sound displacements of about 19 degrees, considerably less accurate than adult values of one to two degrees. (Author/RWB)

This article reviews the history, the use and the reasons for abandonment of the selective adaptation paradigm. The four experiments mentioned in the article show that selective adaptation produces strong reaction time effects, and that items in the adapted category are identified more slowly than unadapted items.

Studies development of auditory temporal acuity in 56 children aged 6 to 12 years and in 8 adults. Improvement in temporal acuity with age was attributed to development of sensory processes and not to age-related changes in nonsensory factors. (Author/BE)

Profiles of three persons (9-11 years old) with extremely reduced masking level difference results (scores which measure binaural release from masking) are reported. It is suggested that tests of the MLD appear to be a useful adjunct of an evaluation battery for patients with presumed auditory perceptual problems. (CL)

Temporal auditory-integration for short-duration, frequency-varying signals was examined in 14 children (9-17 years old) with deficits in auditory memory and reading. No significant differences were found between the experimental and control groups' thresholds as a function of signal class (i.e., fixed-frequency or tone glide) or duration.…

The aim of the present experiment was to determine the locus of the set effect of sentence context on the intelligibility of a member word. (Author)

Investigated adolescent males' recognition of evaluative words spoken near threshold by male and female voices. Closed-style subjects (theoretically characterized by social withdrawal and perceptual blocking) recognized fewer female-spoken (relative to male-spoken) words; this finding is consistent with adaptive-style theory.
