Determines the frequency distribution of Brainstem Auditory Evoked Potential variables (BAEP) for premature babies at different stages of development--normal newborns, infants, young children, and adults. The author concludes that the assumption of normality underlying most "standard" statistical analyses can be met for many BAEP…

Reports a study which shows that subjects can make discriminative judgments of a speaker's height and weight from his tape recorded speech. This ability is not altered by the filtering of the speech signal. (PMJ)

The authors review current brain hemisphere laterality research in relation to music education, concluding that evidence is still insufficient to determine the functions of the left brain and right brain in music perception. They also consider the effects of training on the cerebral processing of music stimuli. (SJL)

A uniprocessor, unidimensional model, based on Krueger's noisy-operator theory, was fitted satisfactorily to data from four published studies of tone comparison. The model predicts faster response time on different judgments because of heterogeneity of difference. (Author/CP)

Analogous auditory and visual central-incidental learning tasks were administered to 24 second-, fourth-, and sixth-grade and college-age subjects to study the effects of modality of presentation on memory for central and incidental stimulus materials. (Author/SB)

Research presented in this paper on the character of infant-directed speech and the nature of infant speech perception abilities from 6 to 12 months suggests that prosody contributes significantly to early analyses of child languages and assists infants in developing root processes of parsing.

Reviews the syntactic priming task, a paradigm involving the presentation of a phrasal or clausal context, followed by the presentation of a target item for lexical decision or naming. Notes that response times are faster for targets syntactically congruent with the preceding context than for incongruent targets. Outlines how to administer this…

Investigated the influence of a talker's face (e.g., articulatory gestures) and voice, vocalic context, and word position in the training of Japanese and Korean English as a Second Language to identify American English /r/ and /l/. Findings revealed significant effects of training type, talker, word position, and vowel. Findings are compatible…

The effects of immediate feedback provided through a wireless headphone FM transmission system were compared to the effects of delayed feedback on inappropriate verbalizations of a 10-year-old with attention deficit/hyperactivity disorder. Results indicate that inappropriate verbalizations decreased during both conditions, although the decrease…

A study examined how 20 adults with postlingual deafness with cochlear implants combined visual information from lip reading with auditory cues in an open-set word recognition task. Word recognition performance was highest for audiovisual presentation followed by auditory-only and then visual-only stimulus presentation, and for single-talker…

Investigates fricative perception in toddlers using repeated tests to control for factors relating to task difficulty and stimulus familiarity. Each subject was tested on a contrast the child produced distinctly in an imitation task and one the child produced as similar syllables. Final perception results were well matched to productive…

Two experiments studied whether altering an auditory stimulus' rate of change affected infants' fixation of changing visual stimuli. Results demonstrated that infants exposed simultaneously to auditory and visual stimulation showed a reduced tendency to fixate on relatively more visually stimulating events. Heart rates also accelerated during…

Examined the discriminant validity of sexual responses to stories of child sexual assault when told from the point of view of a male perpetrator versus that of a female child victim. Results indicate the relevance of changing deviant preferences and enhancing empathy for the victim while treating child molesters. (RJM)

A 5-year-old preschool child with a visual impairment and significant developmental delay underwent training to learn to reach and locate objects from a sitting position and to locate and move toward given objects in the environment using the Infant Sonicguide. Time constraints prevented achievement of the second goal. (Author/SW)

Twelve children (ages 7-8) with attention deficit hyperactive disorder were administered the Selective Auditory Attention Test twice: after the administration of methylphenidate and after the administration of a placebo. Results revealed no simple drug effect but a strong order effect. (Author/JDD)
