This longitudinal study modeled children's complex executive function (EF) development using the Groton Maze Learning Task (GMLT). Using a cohort-sequential design, 147 children (61 males, 5.5-11 years) were recruited from six multicultural primary schools in Melbourne and Perth, Australia. Race/ethnicity data were not available. Children were…

This microgenetic study examined social influences on children's development of analogical reasoning during peer-led small-group discussions of stories about controversial issues. A total of 277 analogies were identified among 7,215 child turns for speaking during 54 discussions from 18 discussion groups in 6 fourth-grade classrooms (N = 120; age…

Reports two studies which examine the cognitive demands of nominal realism tasks. Subjects were kindergartners, first graders and second graders. (Author/JMB)

Examined the relationship between two components of class inclusion (hierarchical classification and quantification of inclusion) and investigated the effects of methodological modifications. Subjects were nine girls and nine boys each from first, second, and third grades. (Author/JMB)

Data representing two styples of approach to the logical abilities of young children are analyzed. The result of this analysis is contrary to popular interpretations of Piaget's views concerning the logical abilities of young children. (ST)

Semantic and cognitive factors governing passive-voice comprehension were studied in kindergarten, first-, and second-grade children. (ST)

Class-inclusion in first grade children was studied by using part-whole comparisons of families of stimuli (e.g., dogs). Results indicated that it was easier to make part-whole comparisons for the family relation than for the class-inclusion relation. (ST)

Tests Piaget's assertion that the anticipation of conservation among otherwise nonconserving children is a pseudoconservation since it is limited to those lacking knowledge of covariation. Number, area, and length conservation tasks and a covariation task were given to 96 children from kindergarten through the fifth grade. (Author/SS)

Children's comprehension and memory for different kinds of information in prose was assessed in two experiments. In the first experiment, 72 elementary school children listened to paragraphs and answered questions about explicit and implicit semantic relationships. The second experiment investigated the relationship between children's initial…

A total of 82 fourth and fifth graders participated in a 15-week intervention program during which they confronted problems requiring formal operational thought. Subjects showed advancement toward formal operations on the pendulum and chemicals problems (Inhelder and Piaget) and on a third problem on immediate and 4-month posttests. (Author/JH)

The Piagetian concept of horizontality was studied in 195 fifth graders to determine the relationship between this concept and memory. (ST)

A study of the development of elementary school children's appreciation of riddles was conducted within the framework of the incongruity and resolution theory of humor. (ST)

A modified anagram task is employed to explore the development of anticipatory imagery and its relationship to reading achievement, complexity of stimulus material, and practice effects. (Author/AJ)

Investigates logical and perceptual determinants of social-cognitive development by examining children's use of consensus information for causal attribution. Results verify the importance of perceptual processes, demonstrating that children can use consensus for person attribution earlier in development than they can for stimulus attribution.…
