Children who are diagnosed with autism spectrum disorder (ASD) often fail to show equivalence class formation. This may be related to their difficulty in learning the programmed baseline conditional discriminations. The present study investigated equivalence class formation after training visual identity-matching performance with auditory…

Auditory speech appears to be linked to visual articulatory gestures and orthography through different mechanisms. Yet, both types of visual information have a strong influence on speech processing. The present study directly compared their contributions to speech processing using a novel word learning paradigm. Native speakers of French, who were…

Speech, reading, and writing are the basic forms of linguistic communication. Therefore, it is very important to diagnose any problems with them as early and completely as possible, particularly in children with special needs. One of the methods that focuses primarily on the diagnosis and therapy of such learning difficulties is the one developed…

Purpose: This study explored visual speech influence in preschoolers using 3 developmentally appropriate tasks that vary in perceptual difficulty and task demands. They also examined developmental differences in the ability to use visually salient speech cues and visual phonological knowledge. Method: Twelve adults and 27 typically developing 3-…

Two experiments examined the effects of multimodal presentation and stimulus familiarity on auditory and visual processing. In Experiment 1, 10-month-olds were habituated to either an auditory stimulus, a visual stimulus, or an auditory-visual multimodal stimulus. Processing time was assessed during the habituation phase, and discrimination of…

The purpose of this experiment was to present redundant auditory information along with written displays to see if first graders would be aided in discrimination between legal and illegal nonwords. Seventy-two middle-class first and second graders of both sexes were given one of three treatments to study the effect of redundant auditory…

We propose an "Enhanced Perceptual Functioning" model encompassing the main differences between autistic and non-autistic social and non-social perceptual processing: locally oriented visual and auditory perception, enhanced low-level discrimination, use of a more posterior network in "complex" visual tasks, enhanced perception…

Results of discriminating and monitoring tasks indicate that performance deteriorates over time when a specific object must be distinguished from previously presented nonspecific objects in a display which changes quickly. The results offer a basis for distinguishing between perceptual and response processes underlying the vigilance decrement.…

THE RELATIONSHIPS BETWEEN AUDITORY AND VISUAL FUNCTIONING AND READING ACHIEVEMENT WERE EXPLORED. AN ADDITIONAL OBJECTIVE WAS TO INVESTIGATE THE INFLUENCE OF DEVELOPMENTAL FACTORS ON THESE VARIABLES. A WIDE RANGE OF AUDITORY AND VISUAL SKILLS WAS SAMPLED IN POOR AND NORMAL READERS AT THREE DIFFERENT GRADE LEVELS (FIRST, THIRD, AND FIFTH). DATA…

One hundred and two third graders were tested on match-to-sample, cognitive style tasks in the visual and auditory modalities as well as a visual-auditory cross-modal task. The results lend support to the relationship between cognitive style and reading performance. (Author/NQA)

The booklet outlines ways to help children with learning disabilities in specific subject areas. Characteristic behavior and remedial exercises are listed for seven areas of auditory problems: auditory reception, auditory association, auditory discrimination, auditory figure ground, auditory closure and sound blending, auditory memory, and grammar…

The result of a number of experiemental studies of human auditory and visual information processing behavior and their possible relationship to the student pilot's acquisition of flying skill were explored in terms of a conceptual model developed for this study. The results were interpreted in terms of the potential interfering effects of the…

To describe and compare the psychosensory functioning of normal children and children with specific learning disabilities, 62 learning disabled and 68 normal children were studied. Each child was given a battery of thirteen subtests on an automated psychosensory system representing various combinations of auditory and visual intra- and…

Many children with learning problems have difficulties with perceptual development. This bulletin, reporting the preliminary findings of a Cooperative Curriculum Project funded under Title III, Elementary and Secondary Education Act, discusses Kephart's definition of sensory motor perception. It defines and suggests activities and materials…

Papers included are the following: aspects of mobility in the blind by J.A. Leonard; the development and analysis of tactual measures of intelligence for the adolescent and adult blind, a summary of a doctoral dissertation by Eoline Christine Cull; an investigation of human visual information transmission, a doctoral dissertation by Ronald Joseph…
