A sample of 44 infants of five months of age showed a significant reaching preference for the apparently nearer region of a computer-generated display. This indicated that the infants were sensitive to boundary flow information for depth at an edge. (RH)

Findings indicate that infants can detect regularity in spatiotemporal series; will develop expectancies for events in the series; and will act on the basis of those expectancies even when their actions have no effect on the stimulus events. (PCB)

Results of a study involving 30 infants of 14, 20, or 26 weeks confirm the existence of distinct developmental phases of attention during the visual preference procedure. Findings suggest a refinement of the use of fixation duration as the major dependent variable in the procedure. (RH)

Describes two studies in which young children were shown pictures that represented sound with postures and contexts, with conventions, and with combinations of information. Shows that the different types of pictorial representation of sound were not equivalent in their ability to evoke a correct interpretation. (HOD)

Two experiments with 167 first-, third-, and fifth-grade children revealed age-related changes in the composition of natural categories. Categorization was investigated via perceptual similarities of objects and conceptual similarities of superordinate classes. The free-classification paradigm (Garner, 1974) was adapted to natural categories,…

For this study, computer technology was used to teach attentional skills to six young children. Prior reinforcement histories of individual stimuli were manipulated to examine whether they are the variable that controls the features of compound cues to which young children attend. (RWB)

Reports on a study conducted in Spain in which the environmental preferences of 11 to 14-year-old children were examined using a collection of photographs. Results include the indication that the environmental attitudes of children attending a 15-day nature camp changed noticeably in at least five different aspects. (TW)

Two experiments examine whether the encoding of location meets criteria defining an automatic process. Automatic processes are not expected to show developmental changes beyond an early age. They appear to be unrelated to intelligence level and unaffected by instructions. Results support Hasher and Zack's automaticity hypothesis. (RWB)

Analyzes the research strategies, stimuli, subjects, statistical strategies, and relative variables in 34 empirical studies on children's representation of three-dimensional objects. The studies fell into three categories: children's representation of spatial relationships within an object, between two objects, and studies that included both. (MJP)
