Discusses definitions of learning disabilities and strategies for identifying and accommodating learning disabled adults during job training. (SK)

Examines development of processing speed in three backward masking studies, where presentation of second stimulus figure (mask) within a critical time interval from arrival of first figure (target) interrupts processing of first. Results indicate that processing time increases until early adolescence; changes are less marked after 13 years of age.…

Significant visual and visual-perceptual problems must be identified in the early school years to save unnecessary stress, frustration, and anxiety. Classroom diagnosis using formal and informal measures can lead to referral to developmental or functional optometrists. (CL)

Observers aged six to 24 years estimated distances between elements in patterns illustrating Gestalt grouping principles of proximity, similarity, closure, and good continuation. Magnitude of distance distortions decreased significantly with age, suggesting that perceptual development includes improving ability to disregard Gestalt groupings when…

A model of mental representations is developed and shown to provide a framework for interpreting research. The content of awareness is characterized as a model of the world capable of simulating future events, anticipating present events, and thereby formulating appropriate actions. Properties of awareness and of underlying processes are…

Discusses a public library film literacy program offered to adolescents and young adults which incorporates films that are not curriculum-oriented and center around specific themes such as self-identity, creativity, speculations, and lifestyles. Seven films selected for program on social issues and viewers' evaluations are highlighted.…

Researched the possibility that four- to six-year-old children are competent and systematic classifiers, at least making classifications by overall similarity. In three experiments, young children classified various sets of multidimensional stimuli that could be organized into catagories by overall similarity or by diminsional attributes. Children…

Reviews the literature dealing with the loci and parameters of visual selective attention. It is maintained that input selection can be found at several points in the course of processing. Specifically, a case is made for very early perceptual selection, called perceptual tuning, which can be based on higher-order conceptual or structural stimulus…

Intended for those concerned with the identification of learning disabilities which involve communicative disorders, the article identifies some areas of confusion regarding visual perception, vision testing, communication, and dyslexia. (IM)

This study investigated whether students' memory retention rate improved when they were provided with blue ink printed material. A pretest, treatment, posttest with control group design was used. The participants were 93 10th and 11th grade students in algebra and geometry courses, and there were 2 classes in each course. The treatment lasted for…

This paper discusses the role of digital technology within the cognitive revolution of the perception of images. It analyzes the traditional values placed on images as a source of cognition. These values are discussed in terms of the ethical and social issues raised by the use of digital image manipulation in so far as the digital era is falsely…

Only a decade ago eye- and gaze-tracking technologies using cumbersome and expensive equipment were confined to university research labs. However, rapid technological advancements (increased processor speed, advanced digital video processing) and mass production have both lowered the cost and dramatically increased the efficacy of eye- and…

Students coming at present to technical universities are accustomed to television and the visual perception is their prime source of information. This is why our civilization is being often labeled as the "civilization of picture". The contemporary psycho-physiological researches, along with the Dale's cone of human perception, also…

Investigated developmental trends in part-whole perception. The effects of the whole on the perception of small parts was greater at the kindergarten level than at the 4th grade; and there was a change in the perception of the parts so that they came to look like the whole in shape. (DP)
