The N2 and P3 components have been separately associated with response inhibition in the stop-signal task, and more recently, the N2 has been implicated in the detection of response-conflict. To isolate response inhibition activity from early sensory processing, the present study compared processing of the stop-signal with that of a…

Behavioral and electrophysiological processing of sequential tones were investigated in reading delayed (RD) and non-reading delayed (NRD) children matched on intelligence and reading level. NRD children performed consistently better on sequencing of tonal patterns. Middle latency event-related potentials from the RD group indicated reduced…

Pulsation threshold (PT) masking was used to assess frequency resolution among infants 3 and 6 months of age and adults. The masker intensity at which the pulsing probe becomes indistinguishable from a physically continuous probe is the PT. A measure of frequency resolution can be obtained by examining the effects of masker frequency on the PT. In…

This paper reports an investigation of gender-indicating acoustic properties of the vocalizations of 73 six- and seven-year-old speakers. Tape recorded samples of these children's isolated vowel and sentence productions were presented in four listening sessions. One hundred and sixteen young adult (age 17-24) female listeners made gender judgments…

The role of memory factors in the vowel discrimination of normal and at-risk 8-week-old infants was examined by studying the categorical versus continuous discrimination of very brief vowels in a nonnutritive sucking paradigm. Discrimination of the silent delay interval between the last familiar and the first novel stimulus was also examined.…

The study investigated perceptual preferences of five autistic children (mean age 10.6 years). Results indicated a weak (not statistically significant) preference for auditory musical stimuli over visual stimuli. Autistic children spent significantly more time than did normals with the musical stimulus. (Author/DB)

The effects of unilateral and bilateral ear occlusion on auditory discrimination in background noise was tested among 36 adults with auditory figure-ground disorders and normal auditory discrimination ability. Results indicated that unilateral occlusion effectively eliminated the figure-ground disorder in most subjects. (Author/DB)

The effects of reduced auditory feedback on spatial and temporal parameters of speech production were investigated using cinefluorographic techniques with three normal hearing women. Results suggested that auditory information plays a role in maintaining dynamic aspects of speech kinematics. Implications for hearing impaired speakers are noted.…

Performance on a dichotic word task was examined with 15 articulatory-impaired children and 15 non-articulatory-impaired children (all between 5 and 9 years old). Results of presenting words under three conditions (free recall, directed right, and directed left) found no significant differences between groups on ear preference. (Author/DB)

Infants five and seven months of age participated in two studies in which two filmed facial expressions were presented with a single vocal expression characteristic of one of the facial expressions. Seven- , but not five-month-olds, increased their fixation to a facial expression when it was sound-specified. Preferences for a particular expression…

Among children four to six years of age who were tested for their detection of melodic transformations, performance was superior for transformations that changed contour, for greater changes in contour, and for faster presentation rates. Melodies transformed by reordering tones were as discriminable as those transformed by inserting novel…

K. Kavale responds to criticism of his earlier meta-analysis assessing the relationship between auditory perceptual skills and reading. R. Gersten and D. Carnine rejoin that the correlations Kavale found between auditory skills and reading achievement scores are of limited pragmatic use to the field. (CL)
