Spatial visualization is a fundamental skill in technical graphics and engineering designs. From conventional multiview drawing to modern solid modeling using computer-aided design, visualization skills have always been essential for representing three-dimensional objects and assemblies. Researchers have developed various types of tests to measure…

Two processing abilities used to solve spatial problems are examined: (1) the analog ability of structural visualization; and (2) the non-analog ability of verbal analytic reasoning. The distinction is based on an evaluation of information processing theory and a review of process-oriented studies of individual differences. Criteria are presented…

Spatial visualization is not yet clearly understood. Some researchers have concluded that two factors or abilities are involved, spatial orientation and spatial visualization. Different definitions and different tests have been proposed for these two abilities. Several studies indicate that women generally perform more poorly on spatial tests than…

Reports research into the visual fixation of 3- to 11-week old infants as they observed adult faces. Reports a dramatic increase in fixations occurred between 5 and 7 weeks for all conditions. (SL)

This study was designed to examine relationships between three variables of analysis/integration skill in visual perception and the tendency to retain differentiated memories of sequential visual images in a sample of 206 university undergraduates. Correlation techniques and factor analysis were used to analyze relationships between the perceptual…

This document is a collection of 12 forms that have been designed to aid school personnel in the processing of standardized achievement tests. The forms adapt to any typical achievement test whether the scale is a classroom or a large school organization. These forms are essentially a visual aid to interpretation. For the pupil there are two forms…

Sex differences in speed of solving mental rotation problems were replicated but college men and women were alike in frequency of use of algorithms to solve problems. The most frequent algorithm involved encoding stimuli in working memory, mental rotation of one to orientation of the other, comparison, and response. (Author/RD)

This study examines the Wheatley Cube as a measure of spatial/visualization ability. The Wheatley Cube is a computer managed task which requires the subject to visualize a three-dimensional workspace and to find an invisible dot located within this space. Thirty-three undergraduate students were administered four tests of spatial/imaginal ability…

This series of activities on spatial relationships was designed to help users acquire the skills of spatial visualization and orientation and to improve their effectiveness in applying those skills. The series contains an introduction to spatial orientation with several self-directed activities to help improve that skill. It also contains seven…

Previous literature on children's visual pattern perception has suggested that preschool children may process hierarchical forms in a manner different from that of older children and adults. Data from some studies suggested that children are holistic processors of pattern information, while other studies characterized children as piecemeal…

Examined the stability of two aspects of infant visual attention derived from the paired-comparison procedure in infants tested at 6, 7, and 8 months of age. The two aspects were novelty preference and exposure time. Suggests that both novelty and exposure-time scores reflect moderately stable but independent characteristics of infant behavior.…

Studies the ability of 5-month-old infants to recall temporal information and use temporal organization by training them to fixate a hierarchically structured or unstructured sequence of stimuli which appeared in four spatial positions. Results are interpreted within a temporal organizational framework; infants appear to use organization within…

Strategic differences in spatial tasks are explained in terms of different cognitive coordinate systems that subjects adopt such as standard versus arbitrary, task-defined axes. A theoretical account of mental rotation of individuals of low and high spatial ability solving problems from psychometric tests is instantiated as computer simulation…

This experiment was designed to investigate effect of verbal instruction alone vs. verbal instruction complemented by simple line drawings; effect of visual testing vs. nonvisual testing; effect of verbal cued vs. free recall on student achievement; effect of order of testing on subsequent achievement; and interaction among type of instruction,…

Four experiments were carried out to examine the different recall strategies employed in a diagnostic test of visual sequential memory. The principal implication of the results is that good and poor readers may not differ with respect to visual memory but in their ability to employ a verbal labeling strategy. (Author/KC)
