A procedure is described for minimizing perspective error when calculating a scaling factor for any subject at any perpendicular distance from a camera, provided the subject touches the ground, and represents one way in which perspective error can be used to provide valuable information. (MJB)

Visual skills are directly related to athletic performance. A visual skill enhancement training program consisting of twelve exercises is offered. (MT)

Study tests 45 four-month-old infants for color constancy using a familiarization, paired-comparison paradigm. Infants tested with a change in illuminant correctly recognized the familiar color under some conditions and failed to do so under others. (Author/RWB)

The sensitivity of 10 moderately mentally retarded and 10 nonretarded adults to changes in environmental spatial structure with and without visual-environmental clues was examined. Both groups showed similar sensitivity to perspective changes without visual cues, but only the nonretarded demonstrated increased accuracy with the visual cues.…

Four experiments investigated three- and four-year-old children's knowledge of projective size-distance and projective shape-orientation relationships. Results indicated that preschool children's understanding of these relationships seems at least partly cognitive rather than wholly perceptive, providing further evidence for the acquisition of…

Provides a visual analysis of Wayne Thiebaud's painting of a San Francisco street scene, "Corner Apartments (Down 18th Street)." Identifies key concepts, provides a brief biography, and suggests four elementary level and five secondary level follow-up activities. (JDH)

A project offering comprehensive vision therapy evaluations and visual-perception testing to juvenile delinquents revealed a high percentage of undiagnosed and previously untreated visual perceptual problems. Treatment has resulted in marked reduction in recidivism and increases in reading skills. (CL)

Argues for the analyzing, studying, and describing of text pages as configurations of columns and lines and as constallations of alphabets. (FL)

Discusses how to stop a spinning object (such as rotating fan blades) by humming and the perception of curious blue arcs around a light. Background information, relevant research, and activities related to these two topics are provided. (JN)

Letter recognition errors may be the result of children going through normal states of development. (Author)

Discusses a controlled experiment in which right and left hemisphere activity determines selected emotional responses to visual stimuli. Findings suggest that each hemisphere has a distinct emotional response. Both hemispheres contribute to the individual's perception of the world. (EB)

This study contributes to the research on the Application of Cognitive Functions Scale (ACFS) (C. Lidz and R. Jepsen, 2001), a new dynamic assessment approach for young children. Dynamic assessment is an assessment tool that follows a test-intervention-retest model, using the teaching as part of the assessment. The ACFS assesses the child's…
