Research is reported which examined the effect of various factors on the frequency of phonological responses. Phonemic order and location of clusters within a syllable affected fusion. Initial stop-liquid clusters fused readily; final liquid-stop clusters rarely fused. Some subjects fused on most or all trials; others fused less frequently.…

A total of 14 infants participated in this study of the recovery of visual orienting by crossmodal stimulation when no new visual information was present. The locus of the crossmodal stimulation (auditory stimulation) was discriminable to the subject. Infants in three age groups were tested on three occasions each separated by 30 days. No…

The role of genetic factors in infant response to redundancy was evaluated through observation of the behavior of three sets of same-sex fraternal twins and six sets of same-sex identical twins to combinations of redundant proprioceptive and auditory stimulation. The twins ranged in age from 6 weeks to 24 weeks. One member of each twin set was…

Analyzed was the performance of 30 children with normal reading and speech skills on various blending tasks. There were three groups of ten Ss each with each group receiving one of three modes of presentation: auditory, visual, or auditory visual. The stimuli consisted of 150 consonant-vowel (CV), vowel-consonant (VC), and…

Delineates the effect of attentional bias on preadolescents' dichotic listening performance by using four different types of stimulus material (words, digits, CV syllables, and melodies) under free recall and directed attention conditions. (HOD)

Rates of stereotypic behaviors in six severely/profoundly retarded children (eight to 15 years old) were observed during varying presentations of auditory beats produced by a metronome. Visual and statistical analysis of research results suggested a significant reaction to stimulus presentation. However, additional data following…

To examine differences between auditory selective attention abilities of normal and cerebral-palsied individuals, 23 cerebral-palsied and 23 normal subjects (5-21) were asked to repeat a series of 30 items in presence of intermittent white noise. Results indicated that cerebral-palsied individuals perform significantly more poorly when the…

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.…

A total of 11 reading-disabled and 11 nondisabled children ages 13 and 14 were presented a list of 10 words at different rates. Immediately after the last word of each list, subjects recalled the words in any order. Results focused on the use of elaborative encoding. (Author/CI)

While all six severely retarded adults increased their work output over the 35 18-minute sesions, it was concluded that the reinforcement contingencies were influential in only four Ss. It was speculated that auditory stimulation may be a more potent motivator than visual stimulation. (Author/CL)

Results indicated that the auditory stimuli intervention was effective in reducing vocal stereotypes of one autistic S across all activities and for the second subject, in two activities. Social validity measures confirmed the effects of the intervention, the importance of decreasing the behavior, and that the intervention itself was not…
