When groups of children were given a test of visual performance designed to measure their dark interval threshold, differences were found between boys and girls and differences were found indicating that those children who had a moderate threshold showed superior reading ability. (MKM)

Tests of intelligence, music audiation, auditory conservation, and visual conservation were administered to two first-grade classes. Data revealed that auditory conservation isn't significantly related to visual conservation but is significantly related to music aptitude, to IQ, and to the interaction of music aptitude and IQ. Instructional…

Infants ranging from 6 to 12 months were randomly assigned to one of three conditions: (1) allowed to look at a specified object, (2) allowed to look at and manipulate it, or (3) allowed to look at the object and to manipulate the transparent box in which it was encased. (JMB)

Tests the hypothesis that children will be better than adults at perceiving depth at large disparities in random-dot stereograms. Subjects were 4, 6, 8, and 25 years of age, with six males and six females in each of the four age groups. (MP)

The ability of neonates to integrate auditory and visual information into a single percept was investigated using a signal detection methodology. Thirty-two infants ranging in age from 2 to 11 days served as subjects. (Author/MP)

The results suggested that profoundly retarded children do show habituation and dishabituation to visual stimuli and are actively storing and processing information about their perceptual world. (Author/DLS)

A general set of leadership functions is developed based on theoretical and empirical considerations and is operationally defined by an interaction coding procedure. (Author)

This study examined the effects of the cochlear hearing loss of 12 adults on two measures of sequential processing that rely on spectro-temporal information: a gap-detection discrimination task and a melody recognition task. It was concluded that cochlear hearing loss deleteriously affects the processes underlying perceptual organization of…

Two experiments examined the effects of common motion, background texture, and orientation on four-month olds' perception of unity of a partially occluded rod. Results indicated that infants' perception of object unity is not dependent on a single visual cue but on a variety of cues including motion, interposition, depth cues, background texture,…

Visual and auditory coding processes in learning-disabled students (SLDs, n=19) and control students (SCs, n=19) were examined. Analysis of decision latencies revealed that with initial task exposure, SLDs responded more slowly than SCs, but confusability patterns were similar. With practice, overall latencies became comparable, while…

Focuses on investigations of infant sensation and perception over the past 25 years. Describes the knowledge base concerning the sensory and perceptual world of the infant in the mid-1960s. Methodological highlights in the study of vision and audition are covered. (RJC)

How the dual-task interference effects, observed when subjects attempted to simultaneously perform two simple tasks, are related to capacity limitations in perceptual processing of complex visual displays was studied. Results for a total of 110 undergraduates in 6 experiments support a 2-component theory of divided attention. (SLD)

Examines the ability to differentiate appearance-reality and Level Two perspective-taking in tactile modality among a total of 92 children aged two-four years in three studies. The results indicate that three-year-olds find tactile appearance-reality and Level Two perspective-taking tasks easier than visual ones. (RJC)

A course in non-visual art offered as part of a general education requirement has both blind and blindfolded students exploring aspects of art, primarily tactile and auditory, usually de-emphasized in art education. (MSE)

This study compared speech intelligibility for sentences spoken either conversationally or in a clear manner under three conditions: auditory only, visual only, and audiovisually. Overall, in each condition, speech intelligibility improved significantly for the tokens of clear speech. Some interaction between speaker and manner of speech was…
