Auditory-visual pattern equivalence and temporal-spatial equivalence of 72 children of 7-17 years were examined. Data indicated that aspects of intersensory integration were still developing between the ages of 13 and 17. Accuracy in performance increased with age for intra- and intersensory matching. (RH)

No differences were observed between six adults and six six-year-olds in measures of frequency selectivity and comodulation masking release. Children were less able to detect signals in noise backgrounds where the signal had perceptual qualities similar to the noise or in noise backgrounds having high degrees of fluctuation. (Author/JDD)

Reviews and critiques a doctoral dissertation that investigated the ability to detect tempo changes. Points out some omissions in the study, suggesting that its brevity caused the author to omit some possible interpretations. Comments that Ellis' research design provides new ideas for research.

Two studies examined the relationship between speech perception and speech production errors in children (N=21 and ages 5 and 7) with articulation disorders. Findings indicated the existence of a subgroup of articulation disordered children for whom production errors reflect perception errors. (Author/DB)

A profile analysis procedure was used with the Carrow Auditory-Visual Abilities Test to aid in the identification of systematic modality preferences in two preschool children with articulation disorders. Critical values are identified to facilitate the identification of the child's strengths and weaknesses at the subtest level. (Author/DB)

The ability of 10 normal-speaking 5-year-olds and 10-normal-speaking 7-year-olds to categorize consonants as "dripping" (stop), "flowing" (fricative), "tongue" (lingual place of articulation), "or "lip" (labial place of articulation) was evaluated. Children's ability to categorize was evaluated as an indicator of their awareness of feature…

This paper presents results of 2 experiments examining effects of signal and masker uncertainty on 17 preschoolers' and 13 adults' detection of tonal signals in noise maskers. Effects of masker uncertainty significantly exceeded those of signal uncertainty. For most adults and some children, distracters produced higher thresholds and shallower…

One experiment determined that the minimum angle at which infants can discriminate 2 sound presentations decreases substantially toward 48 weeks of age. In 3 succeeding experiments, infants aged 16, 20, and 28 weeks were able to discriminate sounds presented to each ear between 50 and 75 microseconds apart. (BC)

The article reviews studies on the assessment of rapid auditory processing abilities. Issues in auditory processing research are identified including a link between otitis media with effusion and language learning problems. A theory that linguistically impaired children experience difficulty in perceiving and processing low phonetic substance…

This paper reviews two models for auditory compensation attending visual loss--structural and strategic. The paper concludes that it is not clear to what extent differences in auditory processing represent variations in underlying capacity, the development of strategies, attentional activation, or multiple factors. Previous dismissals of…

Twenty-one normal hearing college students were presented with non-time-gated and time-gated speech stimuli. Findings indicated that poorer accuracy and longer isolation points were observed at lower signal presentation levels, listener confidence at isolation point was only indirectly influenced by presentation level, and monosyllabic word…

An auditory Stroop task was administered to 20 children with hearing impairment (ages 3-10) and 60 normal-hearing children. Results suggest that the voice-gender and semantic dimensions of speech were not processed independently by children with or without hearing loss. Speech processing by children with hearing impairment was carried out in a…

Fourteen Dutch children with dyslexia were compared with controls on automatic processing under a dual task (motor balance task and auditory choice task) model. Results indicated the dyslexic group was more impaired in the dual task condition than in the single task condition, compared with controls. Findings support the automatization deficit…

A review of 11 studies of auditory brainstem response (ABR) in individuals with autism concludes that the ABR data are only suggestive (rather than supportive) of brainstem involvement in autism. The presence of peripheral hearing impairment was observed in some of the autistic individuals. (Author/DB)

Results of applying the electrophysiological measure of auditory long latency event-related potentials (P3 AERP) on 20 children with central auditory processing disorders before and after a structured treatment program found a significant decrease in P3 latency and a significant increase in P3 amplitude when compared with control subjects who had…
