Examines the relationship between the fantasy development and conservation performance of second grade children. Results suggest that children's ability to fantasize is not significantly correlated with performance on conservation tasks at this age level. (BD)

Examines Piaget's learning theories and his endorsement of the biological viewpoints of Jean Baptiste de Lamarck. Particular points in Piaget's theories and their relationships to Lamarck's biology are discussed. (CP)

A sample of 80 females in grades 6, 8, 10, and 12 were presented with 10 of the Piagetian formal operations tasks. Analyses of the data indicated that as grade increased, mean scores on the 10 tasks also increased. (Author/JMB)

Five arguments are presented as to the inappropriateness of Piaget's "stage of formal operations" as the final stage of cognitive development. (MJB)

A multitrial free recall study assessed whether learning-to-learn and changes in strategy over sessions occurred with children in kindergarten and grade 3. Results showed that grade 3 subjects recalled more than did kindergarten subjects, but no learning-to-learn effect was obtained for either age group. (Author/JMB)

This study assessed the ability of fourth, fifth, and sixth graders and college students to logically include and exclude variables when making inferences about a multivariate "natural experiment" situation. (Author/SB)

In a study of development of organization strategies in rehearsal processes, children in the first, third, and fifth grades were exposed to a memory task which involved multiple overt rehearsal and recall phases. (SB)

This study examined the effects of judgment-contingent feedback and prior knowledge of 3 rules on the conservation learning of 188 kindergarten children. (Author/JMB)

Argues that human behavior cannot be understood without considering the cultural, political and economic dimensions of life. Attention is drawn to numerous erroneous conclusions drawn by behaviorists, with specific reference to the study of childhood and early adolescence. Contends that some of the richest sources are films, short stories and art…

The relation between past history of outcomes and achievement expectancies was examined for 72 elementary school students. (JMB)

Research reports have indicated that children's memories for pictures or events improved between early and later recall sessions in conjunction with operative growth. This study attempted to determine (1) if any intervening operative training task would increase memory improvements, and (2) if exposure to the memory stimulus per se would enhance…

This paper questions the assumption that a central processing deficit exists in the speed of performing mental operations by children as compared to adults. Two hypotheses are proposed and data are cited as evidence. (JMB)

This study is a replication of Piaget and Inhelder's intertask study of conservation and conservation-related tasks involving subjects ranging in age from nursery to second grade and using varying types of vessels. (SB)

This study documented a developmental model of children's understanding of the simultaneity of two emotions. Fourteen children at each of the nine age levels from 4 to 12 were studied. Children were questioned about (1) two emotions of same valence directed at the same target, (2) same valence/different target, (3) different valence/different…
