Analyzes third grade children's performance on the Mueller-Lyer Illusion for whole and partial presentations of the figure. Results do not support Piaget's theory of perceptual development but are consistent with the theory of simultaneous and successive syntheses. (Author/BH)

Examined critical features of tactile and kinesthetic processes by administering 8 traditional psychometric instruments and 14 measures of tactile and kinesthetic perceptual processes to 116 female college students in Australia. Results show, as is consistent with earlier findings, that visual-spatial processes are difficult to separate from…

Neurologically normal individuals exhibit strong leftward response biases during free-viewing perceptual judgments of brightness, quantity, and size. When participants view two mirror-reversed objects and they are forced to choose which object appears darker, more numerous, or larger, the stimulus with the relevant feature on the left side is…

This investigation into the effects of configural properties (properties determined by the interrelationships existing between component parts) used a selective attention task to determine whether intersection is a primary encoding feature or is constructed after slopes and heights are perceived. The method for encoding feature identification,…

Two studies were carried out to measure the difficulties in visual perception which affect the reading abilities of disadvantaged children. The first study involved children in the first grades of eight poverty-area schools. Results reinforced earlier findings that urban disadvantaged children scored poorly on tests of visual perception.…

These two reports discuss remedial classes at the community college level. The first describes a series of tests that had been administered indicating the students had both perceptual and visual problems which interfered with their learning: the Peabody Picture Vocabulary Test, the Purdue Perceptual Motor Survey, and the Frostig Visual Perception…

Most vision screening today concerns itself only with the physical phase of vision, consequently the relationship of vision to learning becomes slighted. Rather, vision should be discussed as it operates when learning takes place through seeing. Vision as it operates for learning is a very complex process--it has physical (acuity), physiological…

Two experiments were conducted to compare the effectiveness of different ways of producing the frames in a remedial self-instructional program intended to improve the ability of Nigerian secondary school students to understand spatial relationships in pictures. (Author/AM)

Appraises current explanations of how visual processing occurs. Highlights the basics of simultaneous and serial levels of processing. Discusses the results of a series of experiments on visual-search tasks and also on the role of prior knowledge in processing. (ML)

Two groups of 15 boys (mean age 8 years, mean IQ 100), both presenting difficulties in academic achievement, but one with and one without visuomotor impairments, were assessed to determine whether poor drawing ability was related to perceptual or motor disorders. (Author)

Research on the cognitive components of academic achievement subjected White South African schoolchildren to several visual perception tests. Results indicated an association between measures of visual perception and tests of reading and arithmetic performance. Cognitive complexity emerged as an important differentiating feature of perceptual…
