Three forms of auditory stimulation were compared as reinforcers with 13 severely mentally retarded adults performing a task to promote cardiovascular fitness. Subjects received stimulation if they pedalled at a specified rate above baseline performance. Results indicated that music was an effective reinforcer in promoting continuous work output,…

In three amplitude discrimination experiments involving a backward masking task, children's rate of perceptual processing was compared to that of adults. Developmental differences in discrimination were compensated for by increases in the psychophysical difference between test tones. No developmental differences in rate of perceptual processing…

Two experiments examined infants' reliance on object shape versus color for word generalization to animate and inanimate objects. Infants were taught labels for either novel vehicles or novel animals using preferential-looking procedure or an interactive procedure. Results of both experiments indicated that infants limited their word…

Investigates the effects of audiovisual media on preschool children's attitudes toward music presentations from "The Lion King" and "Fantasia." Finds that the listening times for music-plus-video presentations of both selections were longer and a majority of the children expressed a preference for "The Lion King" over "Fantasia." (CMK)

Reviews the hypothesis, "phonological bootstrapping," that a purely phonological analysis of the speech signal may allow infants to start acquiring the lexicon and syntax of their native language. Study presents a model of phonological bootstrapping of the lexicon and syntax that helps illustrate the congruence between problems. Article argues…

Presents a distributed connectionist model of the perception of spoken words, employing speech representation that combines lexical and abstract phonological information, with lexical access as a direct mapping on this distributed representation. The article examines the integration of partial cues to phonological identity, showing that the model…

Presented five- and eight-month olds with silent moving and static video images of self, peer, and doll, and sounds of self and nonsocial objects. Found that recognition of one's image develops through experience with dynamic facial stimulation during first eight months. By five months, infants treat their faces and voices as familiar and social…

Two experiments examined role of affective correspondence between signal and outcome in 4-month olds' associative learning. Found that only when consoling infant-directed speech signaled the sad face did infants' visual interest in a checkerboard increase. Arousing infant-directed speech signaling either the smiling or sad face produced positive…

Investigates the role of stimulus repetition during on line aural identification of harmonic sequences by 72 adult beginners. Demonstrates that the first presentation is a powerful image influencing subsequent identifications. Clarifies the role of repetition and provides an explanation of the incidence of repetition in omitted and incorrect…

An acoustic orientation system was developed that employed a portable remote control device keyed to trigger audio tones from modules placed at key locations throughout the user's home and work environments. Results found that the system helped a blind subject to move and work successfully in both settings, and the subject found it easy and…

This article suggests that the development of listening skills should extend to the "soundscape" of nonspeech acoustical information. It presents a model for effective aural processing, identifies categories of information obtained from nonverbal sound, and explores "ear-tuning" or listening exercises that use sound to glean…

Presented successive auditory time gatings of unfamiliar words--familiar, phonologically-related words and familiar, phonologically-unrelated words--to school-age children with and without specific language impairments (SLI). The groups did not differ significantly in the point at which they recognized familiar words, but the subjects with SLI…

Two experiments tested a neo-Piagetian model of verbal short-term memory, comparing it with the articulatory loop model. Findings indicated that the proposed model accounted for effects of M capacity, word length, and presentation modality on short-term memory. The model's fit to the data was acceptable, and parameter estimates were consistent…

The aim of the present study was to investigate differences in brain activation in a family with SLI as compared to intact individuals with normally developed language during processing of language stimuli. Functional magnetic resonance imaging (fMRI) was used to monitor changes in neuronal activation in temporal and frontal lobe areas in 5…

Children typically learn in classroom environments that have background noise and reverberation that interfere with accurate speech perception. Amplification technology can enhance the speech perception of students who are hard of hearing. Purpose: This study used a single-subject alternating treatments design to compare the speech recognition…
