Used new longitudinal clustering technique to identify and compare groups of children with distinct longitudinal profiles of peer social preference during elementary school. Identified a stable popular group, stable average group, and unpopular group, all with decreasing social preference. Groups showed overlap over time with closest corresponding…

The relations of children's internalizing and externalizing problem behaviors to their concurrent regulation, impulsivity (reactive undercontrol), anger, sadness, and fearfulness and these aspects of functioning 2 years prior were examined. Parents and teachers completed measures of children's (N = 185; ages 6 through 9 years) adjustment, negative…

This study compared the effects of two types of incidental learning paradigms and examined the influence of different kinds of stimulus relationships on first and sixth graders' selective learning processes. (GO)

Examines the degree to which experiencing confusion during the acquisition of new academic material differentially affects classroom performance of helpless and mastery-oriented fifth-graders. Provides an initial test of a theoretical approach to understanding differences between male and female performances in different subject areas. (AS)

A total of 72 children, 36 each from first and sixth grades, were given a 70-item study list followed by a recognition test list of equal length. To indicate the relative dominance of features encoded at both ages, labels, pictures, and referents were recombined to form visual, semantic and acoustic distractors. (MS)

Investigated sex differences in mathematical and spatial (visual-analytic) skills in groups of Hispanic, Black, and White students prior to and during adolescence. (JMB)

Investigates age differences in selective attention in a coded visual search task where subjects were given different types of information about target location before trial onset. (Author/SS)

This longitudinal study of children from preschool through fourth grade examined code-related and oral language precursors to reading. Findings indicated that the relationship between code-related precursors and oral language is strong during preschool. During early elementary school, reading ability is predominately determined by kindergarten…

Interviews with fifth graders living in rural and urban parts of the Brazilian Amazon region revealed that children were aware of environmental problems, believed that throwing garbage into the Rio Negro harmed the environment and violated a moral obligation, cared about environmental harm, and supported conservation of the Amazon rain forest. (BC)

Assessed the reading and mathematics abilities of kindergartners and first graders in the fall and spring of the school year. Found that younger first graders made as much progress over the year as older first graders and more than older kindergartners. Findings demonstrated that entrance age was not a good predictor of learning or academic risk.…

Examined strategy outcome perceptions of popular, average, neglected, and rejected third and fifth graders. Found that children's outcome expectations and strategy evaluations varied as a function of peer status, age, and gender. (RH)

Examined the relationship between mental rotation ability and gender differences in Scholastic Aptitude Test-Math (SAT-M) performance among 760 talented preadolescents, college students, and high- and low-ability college-bound youths. Males outperformed females in both mental rotation and SAT-M for all three high-ability groups but not for the…

Observed kindergartners and first graders playing in dyads. Children who were frequent pretenders had more predictable behavior pathways to and fewer exits from social pretend play (BSP) than children who were infrequent pretenders. Children's social interaction increased in complexity sooner after the onset of BSP than of nonpretend social…

Examined misinformation effects in kindergartners' and second graders' long-term recollection. Results of two experiments showed that (1) misinformation effects were related to rate of forgetting but not to age; (2) developmental differences in retention were controlled by forgetting; and (3) reminiscence increased the probability of correct…
