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…

Examines how children's responses to questions about object terms varied across objects and the degree to which children specified common and conventional values for different object dimensions. (HOD)

Reviews the research literature on the abilities of infants to categorize visual information on dot patterns; schematic faces; hue; and orientation. (HOD)

A structured system of visual features is seen to parallel the propositional hierarchy of operations usually associated with the parsing of algebraic expressions. Women more than men were found to depend on these visual cues. Possible causes and consequences are discussed. Subjects were secondary and college students. (Author/DC)

Studies five-year-olds' relative number judgements of small and large number displays with and without perceptual aids. Children were found to respond to local rather than global density differences and to benefit from the provision of perceptual aids on both small and large number displays. (Author/AS)

This study was designed as the first in a series of inquiries to investigate the use of multidimensional scaling techniques for observing and measuring underlying dimensions commonly perceived by viewers. Following a preliminary study to select photographs, 15 university students aged 19 to 45 were presented with stimuli consisting of 34 colored…

A media attribute approach was used in a study which hypothesized that compositional syntactic placement may bridge the processing link between the learner's cognitive capacity and the demands of a simple concept attainment task. Compositional syntactic placement refers to the relative horizontal position of the primary symbol or object within a…

Reports on a study in which children aged 7 to 9 years and 11 to 13 years were asked to judge which one out of three wooden blocks would float, given weight and volume information for each block relative to a block that was known to float. Indicates that judgments may have been based on the size-weight illusion. (HOD)

This exploratory study was conducted to investigate the potential interaction between the media attribute, horizontal screen placement, and a learner's cognitive aptitudes, fluid ability, and visualization. The primary hypothesis tested was that low-ability learners who are without well-developed assembly and control operations should perform…
