This study continues an investigation of how spherical units, compared to cubical units, can facilitate students' units-locating and organizing units in composites. We analyze how Norwegian grade 3 students enumerate 3D arrays with cubical and spherical units. Our results show how spherical units can act as perceptual clues that facilitate…

A study of the use of multiple form dimensions in pattern classification by children in Grades 2 and 5, and adults. Reliability of classification, number and saliency of features selected, and accuracy with which they were used all implied continuous development of perceptual skills. (Author/ED)

Investigated young children's ability to represent three-dimensionality in their drawings. Preschool, kindergarten and first grade children and adults were asked to draw a cube, a house, and a ball presented in a plain form, a form differentially decorated on each side, and in both 2- and 3-dimensional forms.

Children 6 and 11 years of age were given a recall task in which the perceptual salience of the information and the type of conceptual evaluation required for solution (analysis or synthesis) were varied. (Author/JMB)

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)

Presents two experiments which examined: (1) the tendency to make differential cue-producing responses to the values of dimensions that vary within or between settings; and (2) the hypothesis that children have more experience with problems following a two-choice simultaneous discrimination format than a successive one. Subjects were third- and…

Experiment examined the generality of dimensional and cue-location biases in inference and role of directness of information. (Author)

Presents an investigation of the hypothesis that an increase in the salience of the total class dimension should improve class-inclusion performance. Subjects were 220 children in kindergarten through third grades. (SDH)

A matching task was presented to 120 subjects from 6 to 20 years of age to investigate the relative influence of dimensional salience and salience of variability on problem solving. The task included four dimensions: form, color, number, and position. (LLK)

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,…

This paper discusses three studies which examined the interaction of dimensional dominance with the attentional components of alertness and encoding. In Study I, twenty 6- and 7-year-olds observed thirty 3-second exposures of a color, then participated in a 40-trial choice reaction time task in which the familiarized color and a novel color served…

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)
