This article presents a brief overview of the literature pertaining to the use of objects of reference by people with deaf-blindness. It suggests that the establishment of nonsymbolic object use in appropriate routines may facilitate the acquisition of the symbolic use of objects. (MDM)

This study examined whether 49 adults with mild or moderate mental retardation could perform reliably enough on the Penn Facial Discrimination Task to make this a useful research measure for evaluating visual-receptive processing. Results found subjects generally performed well above chance level, that retest reliability was reasonably high, and…

Describes recent developments in video technology and discusses guidelines for its use in the classroom. As a classroom tool, it has tremendous potential for interactive, individualized learning and offers material appropriate to a more visual learning style. (CJS)

Geometric interpretations and derivations of the six trigonometric relationships are demonstrated. Selected for discussion are limiting values, geometric verification of trigonometric identities, a one-dimensional illustration of the Pythagorean relationships, and the geometric derivation of infinite-series relationships. (DE)

This study investigated conditions for optimizing college students' analogical problem solving. Students given pictorial (not verbal) representations of solutions to source problems were better problem solvers, as were students given a longer time. Students who derived personal solution principles to source problems were not superior to students…

Two experiments examined the origins of joint visual attention in 6- to 11-month-olds with a training procedure. Results indicated that joint visual attention does not reliably appear prior to 10 months; from about 8 months, a gaze-following response can be learned; and simple learning is not sufficient as the mechanism through which joint…

Investigates whether an increased use of techniques of visual design in technical communication improves instructional materials intended for novice writers. Finds that instructional materials incorporating basic visual design principles are more effective than those that are primarily verbal, and that less-capable writers benefit most from…

Comparison of 13 children with mild-to-moderate sensorineural hearing loss but normal language skills and 12 children with normal hearing and development found no significant group differences on three verbal metaphor tasks (comprehension, preference, and completion), and one visual metaphor task. (Author/DB)

Three experiments examined whether 8.5-month-olds considered an object's width and compressibility when determining whether it could be inserted into a container. Results suggested that infants realized that large balls could fit into large but not small containers, whereas small balls could fit into both containers. Infants understood that large…

Reviews and discusses the literature on visual design and visual cognition; summarizes the results of an empirical study that investigated whether computer screen design with good visual design principles influence the learning process; and identifies challenges encountered in conducting research on screen design with respect to achievement…

Presents research on and discusses the redundancy effect, consistent with a dual-channel theory of multimedia learning in which adding on-screen text can overload the visual information-processing channel, causing learners to split their visual attention between two sources. In research, lower transfer performance also occurred when interesting…

Our social worlds are visually saturated. A feature of post-modern society is its relentless traffic in images, often borrowed from diverse times and places, and patched together in ever changing ways. This traffic serves commercial purposes, shapes identities, and increasingly stands in for reality itself. As a newspaper columnist noted, "most of…

This study investigated the ability of color and motion to elicit and maintain visual attention in a sample of children with cortical visual impairment (CVI). It found that colorful and moving objects may be used to engage children with CVI, increase their motivation to use their residual vision, and promote visual learning.

This article describes a hands-on activity in which students convert decimals to fractions, measure, make scale drawings, use algebraic formulas, and use visualization to construct a three-dimensional physical model of a portion of the seafloor. In the process, they learn about sound, speed, and ocean exploration. (Contains 2 figures.)

This study examined how school-aged children process different grammatical categories. Event-related brain potentials elicited by words in visually presented sentences were analyzed according to seven grammatical categories with naturally varying characteristics of linguistic functions, semantic features, and quantitative attributes of length and…
