Reports on four experiments on pattern perception in four-month-old infants. The first experiment examined preference for patterns varying in structure; the second examined encoding patterns from different subset sizes; and the last two experiments examined changes in the size, position, and orientation of the habituation pattern. (HOD)

A series of three experiments was conducted to assess the comprehension of four types of cross-modal (synesthetic) similarities in children and adults. Both perceptual and verbal (metaphoric) modes were tested. (PCB)

A series of six experiments compares young children's competence in attributing absence of knowledge (ignorance) to their competence in attributing a false belief to the other. (HOD)

Four experiments assessed converging aspects of four-month-old infants' perceptions of visual patterns. Results together corroborate and extend previous findings that vertical symmetry has a special status in early perceptual development and that infants can perceive pattern wholes. (Author/AS)

Examines the ability to differentiate appearance-reality and Level Two perspective-taking in tactile modality among a total of 92 children aged two-four years in three studies. The results indicate that three-year-olds find tactile appearance-reality and Level Two perspective-taking tasks easier than visual ones. (RJC)

Compares estimates of monocular visual resolution of children 6- to 36-months of age with three psychophysical procedures: the Probabilistic Estimation by Sequential Testing (PEST), a modification of the PEST procedure, and the method-of-constant stimuli. (HOD)

Describes preschool children's ability to simultaneously perceive multiple aspects of an object in two experiments during which three- to five-year-olds were asked to describe part/whole pictures. (HOD)

Describes two studies that demonstrate young children's perception of color materials differs from that of adults in two ways: (1) the stimulus dimensions of hue, chroma, and value appear to result in somewhat more separable perception for young children than for adults, and (2) the perceived similarities the color materials are not the same for…

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)

Reports on three experiments that investigated why young children's perceptions of bimodal speech are less influenced by the visual component of speech than adults' perceptions are. Results argue in favor of the explanation that children are poorer lipreaders than adults. (HOD)

The effectiveness of training procedures which used visual-visual arbitrary matching, blocked-trial matching-to-sample, and successive discrimination training to teach visual-visual discrimination of two-dimensional forms was evaluated with two men having severe mental retardation. Results indicated that the procedures did establish conditional…

The processing of mental structures in perception appears to be serial, in that viewers can fill in missing parts from an impoverished stimulus following a top down process. To investigate the effects of unfamiliarity, complexity, and legibility on object and layout perception of unfamiliar stimuli, ten subjects were shown one of four ribbon…

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

Applies the analytic technique of maximum likelihood factor analysis to the intercorrelations of the Wechsler Intelligence Scale for Children-Revised's subtests as a means for assessing more or less differentiation and integration. (HOD)

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…
