Cardinal-ordinal abilities and attentional preferences of kindergarten nonconservers, kindergarten conservers, and third grade conservers of number were compared by employing standarized versions of Piagetian cardinal-ordinal tasks and a triad preference task. (Author/JMB)

The specific hypothesis tested by this research is that children are able to attend to multiple cues simultaneously and are able to use the information contained in these cues. (Author)

This study had two major purposes: to examine the effects of dimensional salience upon the learning of conjunction and disjunction rules, and to investigate an alternative to the prevailing cognitive-change accounts of developmental differences in multidimensional problem solving. The relative salience of each of four stimulus dimensions (form,…

Reports two experiments which examined developmental changes in the patterns of preference for varying degrees of perspective while controlling for the station point used in viewing. Subjects were 28 preschool children (age four years), 23 elementary school students (age six years) and 30 college students from introductory psychology classes. (MP)

Coordination and integration of class information was examined using a multidimensional similarity judgment task in which four- and nine-year-old children rated the similarity of pairs of stimuli sharing either one or two attribute values. (Author/MP)

A visual search task was used to assess developmental changes in elementary school children's selective attention to specified portions of a visual display. (Author/SB)

A task was used in which subjects at three different Piagetian stages of intellectual development were to induce the missing relationship in different triadic situations. (Authors)

Subjects were trained against their initial dimensional preference in a two-dimensional simultaneous discrimination learning task. (RH)

Uses the transposition paradigm to compare the influence of the adjectives "same" and "different" on the test choice of 5- and 9-year-old children. (Author/SDH)

Results showed that reversal shift was easier than extradimensional shift and that relative shift difficulty was unaffected by instructions, in contrast to findings with college-age subjects. (Authors)

Children's use of the middle concept was assessed in two developmental studies. Experiment 1, with kindergarten through fifth-grade students, showed marked improvement in the mastery of the middle concept across elementary grades. In Experiment 2, discrimination pretraining with two nonoverlapping stimulus sets transferred to the novel test…

Purposes of this study are to determine the effects of (1) preassessed dimensional salience upon performance in a bi-dimensional matching task, and (2) pretraining conditions expected to facilitate bi-dimensional processing. An additional aim was to elucidate a model of development involving changing salience hierarchies by comparing the effects…

Presolution reversal prevented or significantly retarded learning in kindergarten and first-grade children but did not hinder learning in fifth-grade children. (Authors)

Results suggest that selective attention is a multifaceted skill, with development of its parts progressing at different rates. (Author)

This study was designed to answer the following question: which of four commonly used art styles (photographic, representational, cartoon, and expressionistic), employed in children's tradebooks, would first, second, and third grade children prefer when (a) pictures only were viewed, and (b) text content (informational or fanciful) accompanied…
