A large part of the empirical research in the field of visual attention has focused on various concrete paradigms. However, as yet, there has been no clear demonstration of whether or not these paradigms are indeed measuring the same underlying construct. We collected a very large data set (nearly 1.3 million trials) to address this question. We…

Human visual perception is a fundamentally relational process: Lightness perception depends on luminance ratios, and depth perception depends on occlusion (difference of depth) cues. Neurons in low-level visual cortex are sensitive to the difference (but not the value itself) of signals, and these differences have to be used to reconstruct the…

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…

The diagnosis and treatment of early learning problems and their relation to visual development is the subject of a series of 12 articles. The optometric viewpoint expressed is that vision is learned. A child's method of organizing his world, and manifestations of his disorganized behavior, including poor early academic achievement, probably…

This report presents the results of a study designed to evaluate the Johnson O'Connor Research Foundation's (JOCRF's) measurement of structural visualization. Three experimental tests--the Incomplete Open Cubes Test, the Guilford-Zimmerman Spatial Visualization Test, and Raven's Advanced Progressive Matrices--were added to the JOCRF's test battery…

The project's purpose was to determine whether attention to the task during testing was a confounding variable in measures of visual perception ability. Samples of 30 perceptually handicapped (PH) and 30 normal subjects (N) were randomly selected from children so classified on the Frostig DTVP, providing they had IQ scores between 85 and 115 on…

This study investigated the relationship between intramodal and intermodal information processing and performance on traditional age appropriate tests of spatial and perceptual-motor abilities. The ability of 65 normal kindergarten, first grade and second grade children to match to either a tactile or a visual standard was assessed with a modified…

Previous research has demonstrated that bizarre imagery facilitates long-term recall of noun pairs. A study investigated the effects of bizarreness when more pronounced delays were used. Subjects, 40 introductory psychology students from Illinois Benedictine College, were shown 30 plausible and 30 bizarre scenes at a viewing distance of…
