For over two decades, Dillman's classic text on survey design has aided both students and professionals in effectively planning and conducting mail, telephone, and, more recently, Internet surveys. The new edition is thoroughly updated and revised, and covers all aspects of survey research. It features expanded coverage of mobile phones, tablets,…

Investigates the effect of target size and presence, intensity, and location of sound on the visual following of infants one and two months of age. (Author/RH)

The major purpose of this study was to examine bimodal coordination of featural stimuli in infancy. Specifically of interest was infant sensitivity to the auditory and visual combinations that characterize male and female stimulus configurations. A total of 27 male and 27 female subjects of 3, 6, and 9 months of age participated in the study.…

Discrepancy between angl head turn and loudspeaker location was measured on infants in auditory-alone and auditory-visual trials. Age and loudspeaker location had no effect on performance in auditory-visual trials. However, in auditory-alone trials, there were significant age differences. (PCB)

Seven-month-old infants looked at pairs of slides of two and three objects while listening to either two or three drum beats. Study data call into question the suggestion that the influence of auditory information on infants' attentiveness to a visually presented numerical event is mediated by cross-modal matching of numerical information.…

This paper summarizes the results of a review of the empirical literature (1990-2005) focusing on use of assistive technology as a self-management tool for persons with intellectual disabilities. Forty investigations were identified which provided information on assistive technology to assist persons with disabilities to initiate and complete…

Three experiments tested for developmental changes in attention to auditory and visual signals. Results showed that adults and seven-year-olds tended to allocate their attention to vision rather than audition when no precue was provided. While not entirely consistent, results with four-year-olds suggested a similar biasing of attention to vision.…

An experiment was designed to demonstrate that infants as young as 3 months of age would show face/voice coordination in matched and mismatched conditions if exposure trials were extended to 1 minute in duration. A total of 16 infants participated in each of four experimental conditions. Conditions were (1) mother present with mother's voice…

Examines, in two experiments, 5-month-old infants' sensitivity to auditory-visual specification of distance and direction of movement. One experiment presented two films with soundtracks in either a match or mismatch condition; the second showed the two films side-by-side with a single soundtrack appropriate to one. Infants demonstrated visual…

Examines the relationship between preschool children's (n = 96) cognitive processing of video (V) and audio (A) information on television under four conditions: A/V match, A/V mismatch, V alone, and A alone. Results suggest that in regular television programs the video material simply appears to be more salient and more memorable than the audio…

This study evaluated whether listeners can distinguish human brainstem auditory evoked responses elicited by acoustic clicks from control waveforms obtained with no acoustic stimulus when the waveforms are presented auditorily. Detection performance for stimuli presented visually was slightly, but consistently, superior to that which occurred for…

Examines the development of intermodal perception in infancy by means of a new method, the intermodal learning method. Results support the claim that only subjects who had been familiarized with appropriate and synchronous film and soundtrack pairs showed evidence of intermodal learning. (Author/RWB)

Preschool children's evaluation and integration of visual and auditory information in speech perception was compared with that of adults. Results were used to test current views of the development of perceptual categorization and speech perception. (Author/RH)

Results showed that infants can differentiate dynamic, multimodal expressions as early as five months of age; can distinguish dynamically distinct expressions before similarly animated expressions; and seem to rely more on the voice than the face in making these discriminations. (RH)

Five young adult females with mild mental retardation were given match-to-sample training to develop four classes of equivalent stimuli. All subjects demonstrated development of all possible equivalence classes involving these stimuli. For four of five subjects, the classes that included auditory stimuli developed more rapidly than those that did…
