Three experiments with observers aged 6 to 21 years of age examined the integration of shape information over successive glances. Results indicated age-related improvements in the sequential integration of shape information, both when integration occurs through successive glimpses over space and when information is separated only in time.

Explores children's judgments of the relative effectiveness of four memory strategies (looking, naming, rehearsing, and categorizing.) Strategy judgment data were analyzed using Thurstone's Method of Paired Comparisons. (Author/NH)

Five-, five-and-a-half-, and seven-month-old infants were tested for sensitivity to relative size as distance information. Infants viewed two equidistant, different-sized objects presented side by side and reaching was used as dependent measure. Findings revealing five-and-a-half- and seven- but not five-month-olds were sensitive to relative size…

Addresses limitations of previous research by testing second-, fourth-, and sixth-grade children on three measures: an open-ended interview, a story-recognition task, and a questionnaire about the importance of different characteristics to friendships and acquaintanceships. Friendship expectations based on dispositional characteristics increased…

Second-, fourth-, and sixth-grade children were tested on a multiple-classification task to investigate the relationship between age and observational learning. (Editor)

The developmental hypothesis that behavioral differences between subjects in the two temporal separation conditions would decline over grades was supported by the data. (Author)

Author challenges the findings of Helene Borke who presented evidence interpreted as demonstrating that children as young as 3 years of age were able to successfully abandon their own egocentric perspectives and adopt the points of view of others. Rejoinder by Borke is presented in PS 502 130. (MB)

Main effect of reinforcement for mean response latency indicated that subjects took longer to respond under disapproval than under approval or silence. (Authors)

Younger men are both less engaged from the world and more efficient processors of information than older (especially less educated) ones. (Authors)

Results showed a significant relation between age and role taking, and between type of response required and role taking. However, emphasizing the difference in perspectives between self and other was not shown to facilitate role-taking performance. (JMB)

Children ranging in age from 4 to 19 years (n=106) were asked to pronounce French words that they heard pronounced by a native French speaker. Results showed that pronunciation improved with age up to eight and nine years and decreased thereafter. (JMB)

Results showed that first-grade children were less likely to follow a task-based fair-play rule than were third graders when one of the other children was larger and older. When dealing with same-size age-mates, however, first graders were no less likely to follow a task-based rule than were third graders. (Author/CM)

This study is a longitudinal follow-up analysis of children's performances on a number of Piagetian concrete operations tasks dealing with conservation and transitive inference. Subjects were 102 children selected from kindergarten and grades 1, 3, and 4. (Author/MP)
