The developmental change from global toward dimensional classifications, usually observed in vision, was investigated in haptics with stimuli varying according to their size and roughness. Results indicated that, although more overall similarity classifications were observed in children than in adults, this kind of classification was never…

The development of two structural principles, hierarchical complexity and interruption, was examined in a new domain: two-dimensional pictures. Subjects were 60 4-to 5 1/2-year-old children. (Author/MP)

This study compared the use of discrete and relational aspects of visual configurations in making similarity judgments. Subjects were 3-, 4-, 5-, and 8-year-old children and adults. (BD)

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,…

As children grow older they show an increasing preference for classifying objects on the basis of shape rather than color. To clarify the nature of this "dimension preference," children of ages 3 1/2 to 6 1/2 years were given a method of triads test of dimension preferences, followed (after a week's delay) by a component selection task. The most…

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)

Examines, in three experiments, infant sensitivity at 20, 30, and 36 weeks of age to 3-dimensional structure of a human form specified through biomechanical motions. Findings are interpreted as suggesting that infants, by 36 weeks of age, are extracting fundamental properties necessary for interpreting a point-light display as a person. (Author/BE)

This investigation also studied the relationship between gestational age and preferences for contour. (CB)

In the course of two experiments, groups of kindergarten, second, fourth, sixth grade and college students received several discrimination problems to investigate hypothesis testing behavior. (Authors/MB)

This study investigates the developmental changes that occur in the attending behavior of children engaged in a relatively simple classification task, and attempts to reaffirm the existence of developmental changes in stimulus preferences and in the ability to employ double classification systems. Subjects were 24 preschool and 24 first grade…

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)

Results show that both kindergarten nonconservers and kindergarten conservers found height most salient. Third-grade conservers found quantity most salient but could easily attend to height and width. (Author/CB)
