Previous studies indicate that the benefits of dividing an information processing load across both cerebral hemispheres outweigh the costs of interhemispheric transfer as tasks become more difficult or cognitively complex. This is demonstrated as better performance when two stimuli to be compared are presented one to each visual field and…

Previous laterality studies have implicated the right hemisphere in the processing of metaphors, however it is not clear if this result is due to metaphoricity per se or another aspect of semantic processing. Three divided visual field experiments varied metaphorical and literal sentence familiarity. We found a right hemisphere advantage for…

Virtual reality (VR) technology has demonstrated effectiveness in a variety of technical learning situations, yet little is known about its differential effects on learners with different levels of visual processing skill. This small-scale exploratory study tested VR through quasi-experimental methodology and a theoretical/conceptual framework…

This article describes the characteristics of patrons with learning disabilities (LD) and how these characteristics might affect library use. The lack of services for college patrons who have learning disabilities (LD) in this decade is much like the lack of adequate and appropriate services for high school patrons with LD in previous decades. The…

This study examines possible connections between second language competency and frequency and type of gesture use (illustrators, compensatory illustrators, adaptors, emblems, regulators, and affect displays). To this end, 75 students enrolled in beginning, intermediate, and advanced college-level Spanish courses were videotaped while conversing in…

This study tests the hypothesis that dyslexia and dyscalculia are associated with two largely independent cognitive deficits, namely a phonological deficit in the case of dyslexia and a deficit in the number module in the case of dyscalculia. In four groups of 8- to 10-year-olds (42 control, 21 dyslexic, 20 dyscalculic, and 26…

Two methods are used to test the hypothesis that natural categories have reference point stimuli in relation to which other stimuli of that same category are judged. (Author/DEP)

Eight visual effects of interest in a discussion of perception and a ninth, complex effect requiring prior preparations and polaroid filters are described. (Author/JH)

A discussion of how three-dimension might be used for education. (HB)

This essay was an attempt to develop a conceptual model of creative visual intelligence, based on an analysis of the behaviors of highly productive visual artists. (Author/RK)

Several of the more familiar Illuminating Engineering Research Institute projects which have been chronicled progressively during the past several years are discussed in this report. Those elaborated on are--(1) visual performance and illumination, (2) roadway visual tasks, (3) color preference studies, (4) glare from large sources, (5) discomfort…

Two experiments with 18-week-old infants employed an interference paradigm to study infant visual memory for faces. (Author/JMB)
