The study investigated two neurophysiologic components of event-related brain potential during auditory and visual target detection tasks with 11 non-retarded autistic children, 9 retarded autistic children, and 16 normal subjects, aged 15-19. Results were consistent with the hypothesis that non-retarded autism involves abnormal attentional and…

Five studies examined the contributions of syllable-ordering and rhythmic properties of syllable strings to 6- and 9-month-old infants' speech segmentation. Results indicate that the capacity for integrating multiple sources of information in speech perception emerges between 6 and 9 months, in rough synchrony with the emergence of integration in…

This study compiled a comprehensive early auditory processing skills assessment battery and evaluated the battery to toddlers with (n=8) and without (n=9) early recurrent otitis media. The assessment battery successfully distinguished between normal and deficient early auditory processing development in the subjects. The study also found parents…

When presented with stimuli that contain illegal consonant clusters, Japanese listeners tend to hear an illusory vowel that makes their perception conform to the phonotactics of the language. Assesses an alternate hypothesis that this illusion is due to a top-down lexical effect. (Author/VWL)

In an attempt to address the issue of bimodal coordination of featural stimuli, the sensitivity of 3-month-old infants to the auditory and visual components of male and female stimulus configurations was examined. Measures were made of the infants' visual attention to a male or female face while they listened to a male voice, female voice, or to…

Two detection experiments were conducted with short lists of synthetic speech stimuli where phoneme targets were compared to syllable targets. Results suggest that phonemes and syllables are equally basic to speech perception. (Author/RM)

Kaufman Assessment Battery for Children scores obtained by 20 Down's syndrome children (ages 8-12) were compared with scores of 20 younger siblings and 20 nonretarded children matched for mental age. Among results were that Down's syndrome children performed significantly better on subtests employing visual as opposed to auditory channels of…

Describes two studies in which young children were shown pictures that represented sound with postures and contexts, with conventions, and with combinations of information. Shows that the different types of pictorial representation of sound were not equivalent in their ability to evoke a correct interpretation. (HOD)

Article introduces a framework for the recognition stage of auditory information processing. (Author/ML)

The perceptual-linguistic stimulus distinction for auditory stimuli was examined with 35 trainable and severely retarded (age 8 to 20) and 31 nonretarded (age 3 to 5) students. Retarded and nonretarded students performed similarly on auditory-perceptual stimuli. Nonretarded students performed significantly better than did retarded students on…

A series of possible explanations for learning disabilities (LDS) couched in terms of information processing capabilities was tested by comparing the performance of LDS children on several types of information processing tasks with that of a control group. Subjects were 28 LDS children (10-11 years old) and 24 elementary school students of the…
