The ability to recall correctly ordered information was examined using two auditory tasks (narrative recall and digit span) and a nonverbal, visual task, with 47 individuals with Down's syndrome (ages 5 to 20) and 47 mentally aged-matched children. Although Down's syndrome subjects recalled less information than controls, no differences in the…

Studied whether patterns of developmental progression in reality monitoring were present in visual and auditory modalities and the role of cross-modal imagery in reality-monitoring tasks. Found scores revealed evidence of developmental progression in both auditory and visual source-monitoring tasks, but no effect of cross-modal imagery. (Author)

Assessed development of infants' sensitivity to two nested amodal temporal relations in audible and visible events. Found that sensitivity to synchrony was present by 4 weeks, remaining stable across age. Sensitivity to composition emerged by 7 weeks, increasing dramatically with age. Noted pattern of increasing specificity in perception…

Examined two aspects of the specificity of practice hypothesis using a tracking task. In one experiment, visual or auditory feedback about performance was provided. In a second experiment, visual and auditory information were combined. Both experiments supported the specificity of practice hypothesis. Instructing participants to attend to one…

The purpose of this paper is to describe a software package that can be used for performing such routine tasks as controlling listening experiments (e.g., simple labeling, discrimination, sentence intelligibility, and magnitude estimation), recording responses and response latencies, analyzing and plotting the results of those experiments,…

Children with autistic spectrum disorder (ASD) may have poor audio-visual integration, possibly reflecting dysfunctional "mirror neuron" systems which have been hypothesised to be at the core of the condition. In the present study, a computer program, utilizing speech synthesizer software and a "virtual" head (Baldi), delivered speech stimuli for…

This study examined the relationship between auditory, visual, touch, and oral sensory dysfunction in autism and their relationship to multisensory dysfunction and severity of autism. The Sensory Profile was completed on 104 persons with a diagnosis of autism, 3 to 56 years of age. Analysis showed a significant correlation between the different…

The sentence processing abilities of a conduction aphasic adult woman with a documented phonological coding deficit were investigated in tests of auditory and visual sentence comprehension of reversible active and passive sentences and spatial prepositions, sentence production through story completion and picture description, and repetition of…

The authors review the history and current status of six areas of inquiry into lateralized cerbral hemispheric functions (cerebral dominance) related to language and learning disabilities. (LC)

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…

A DEVELOPMENTAL STUDY OF PERCEPTION AND ITS RELATIONSHIPS TO READING AS MEASURED BY THE CALIFORNIA READING TEST, THE GATES- MCKILLOP DIAGNOSTIC READING TEST, A WORD REVERSAL TEST, AND A REVERSED WORDS IN CONTEXT TEST IS REPORTED. THE PERCEPTUAL TASK OF MATCH ADJUSTMENT WAS USED AS THE SPATIAL ORIENTATION MEASURE AND FOR BOTH SHAPE AND SIZE…

A LONGITUDINAL STUDY WAS PERFORMED WHICH FOLLOWED THREE GROUPS OF CHILDREN (CULTURALLY DISADVANTAGED, AVERAGE, AND CULTURALLY ADVANTAGED) THROUGH GRADE THREE IN AN ATTEMPT TO DETERMINE THE RELATIVE IMPORTANCE OF THE DEVELOPMENT OF CERTAIN PERCEPTUAL FACTORS ON SUCCESS OR FAILURE IN BEGINNING READING. INSTRUMENTS USED WERE SELECTED TO IDENTIFY…

A discrete color naming paradigm was used in two experiments examining activation along orthographic and phonological dimensions in visual and auditory word recognition. Subjects were 80 college students who were presented with a prime word, either auditorally or visually, followed 200 milliseconds later by a target word printed in a color. The…
