Suggests that designing home-based interventions as longitudinal development research (rather than outcome evaluation) can provide valuable knowledge about ecological factors that affect the development of competence in parents and children and about effective ways to support families. (Author/MP)

Thirty-four boys and girls between the ages of four and nine were interviewed on their conceptions of positive justice and parental authority and were then reinterviewed one and two years later. Results suggested that stagelike development in children's social reasoning proceeds gradually, with important continuities in children's social cognition…

The degree to which judgments of ability, effort, and performance conform to the prediction of Harold Kelley's theory of causal schemata was examined at four age levels (kindergarten, third grade, fifth grade and college). Author/MP)

The processes by which children construct images of anticipated end states of a transposition movement were examined on two tasks. Results support Piaget's (1977) hypothesis that reasoning on the basis of state correspondence defines a developmental level which precedes the development of transformational thought. (Author/MP)

According to Hypothesis (H) theory, learning should be very difficult when the number of Hs the subject samples from is very large and/or the correct H is not available. These assumptions were tested with third- and fourth-grade children. In general, results supported these assumptions. (Author/MP)

Younger and older children were asked to label pictures of nonprototypic, container-like objects in an effort to test Nelson's theory regarding the primacy of the functional core in young children's meaning structures. Contrary to expectations, the older, intermediate age children were influenced more by functional context than were the younger,…

After eight weeks of exposure to divergent-thinking situations in large and small groups and on an individual basis by specially-trained preservice teachers, experimental group kindergarten children were significantly superior to control group subjects on three measures of verbal creative thinking. (Author/RH)

Second graders, sixth graders, and college students served in two experiments designed to assess (1) the selection and use of landmarks during route learning and (2) the coordination of successive environmental experiences into an overall configuration. (Author/RH)

Infants five- and seven-months-old were sequentially shown three stimulus arrays of visual elements, only one of which was capable of producing subjective contours. An infant habituation control procedure was used to test infants' abilities to discriminate the arrays. (Author/RH)

Results of two experiments minimizing verbal encoding and response demands indicate that when the ceiling effects in no-mask target recognition are removed, the visual information processing rates for children and adults can be considered equivalent. (Author/RH)

Two-month-old infants were examined to determine whether, during localization of peripheral target, step size and number of steps were determined prior to the first saccade in a localizing series. It was found that on the majority of trials, a series of saccades was made toward the target hemifield. (Author/RH)

Preschoolers interpreted mental verbs with respect to their mental state in contrast to external state. These children were nontheless ignorant of definitive distinctions between the mental verbs, completely confusing cases of remembering, knowing, and guessing. (Author/RH)

In a series of five experiments, young children (two- and three-year-olds) were presented with novel objects in which perceptual and functional features varied independently. Results indicate that early conceptualizations and word meanings are perceptually based when perceptual and functional features are independently available. (Author/RH)

Subjects ranging in age from 7 to 12 years selected correct story completion alternatives significantly more often when these alternatives were similes than when they were semantically equivalent metaphors, and when alternatives specifically denoted the referent of the metaphorical comparison than when the identity of the referent had to be…
