This study examines associations between leisure reading and reading skills in data of 2,525 students followed from age 7 to 16. As a step further from traditional cross-lagged analysis, a random intercept cross-lagged panel model was used to identify within-person associations of leisure reading (books, magazines, newspapers, and digital…

This study explores the co-development of two related but separate reading skills, reading fluency and reading comprehension, across Grades 1-4. A bivariate biometric dual change score model was applied to longitudinal data collected from 1,784 twin pairs between the ages of 6 and 10 years. Grade 1 skills were influenced by highly overlapping…

This study examined children's expectancies about interactions with own- and other-gender peers. Goals were to examine expectancies about the outcomes related to own- versus other-gender group interactions, assess cohort and temporal changes in expectancies, and assess the effect of expectancies on school-related outcomes. Students in second and…

This study assessed the genetic and environmental contributions to peer difficulties in the early school years. Twins' peer difficulties were assessed longitudinally in kindergarten (796 twins, "M"[subscript age] = 6.1 years), Grade 1 (948 twins, "M"[subscript age] = 7.1 years), and Grade 4 (868 twins, "M"[subscript…

Children and adolescents evaluated group inclusion and exclusion in the context of generic and group-specific norms involving morality and social conventions. Participants ("N" = 381), aged 9.5 and 13.5 years, judged an in-group member's decision to deviate from the norms of the group, whom to include, and whether their personal…

Do preadolescent sport self-concepts influence subsequent sport performance? Longitudinal data (Grades 3, 4, and 6) for young boys and girls (N = 1,135; mean age = 9.67) were used to test reciprocal effects model (REM) predictions that sport self-concept is both a cause and a consequence of sport accomplishments. Controlling prior sport…

Investigates assumptions young listeners may make about speaker authoritativeness. First and fourth graders were asked how the protagonist in a story would respond to what could be interpreted as redundant directions. Stories varied in terms of age and certainty of speaker. (Author/RH)

It was hypothesized that young children would have more trouble interpreting instructions given in the "Y because X" form than the "because X, Y." (SS)

Study demonstrates that children, like adults, do have lower tachistoscopic recognition thresholds for good than for bad words. (Authors)

Studied the verbal-nonverbal consistency principle to infer truth and lying in two experiments which involved 117 children in kindergarten, second, and fourth grade. Findings in both experiments indicated that the use of the verbal-nonverbal consistency principle increased with age. (RJC)

When first, fourth, and fifth grade speakers played a referential communication game with a fictitious listener, they were more likely to give redundant messages to listeners with whom they had no common shared experience or to strangers than to listeners with whom they had shared a previous experience. (RH)

Experiments revealed that children seemed able to integrate multiple sources of information but were more dependent on clue support and generally less likely to infer reason than adults. Children were more likely than adults to reject premise as an explanation of outcome. Only fourth-graders and adults modified inferences in response to resolution…

Tested hypothesis that understanding validity of inference is a relatively late development by asking fourth and seventh graders and college students to sort sets of deductive arguments. None of fourth graders, 45 percent of seventh graders, and 85 percent of college students used validity as basis for distinguishing arguments. Experiments…

Explores the factors associated with expected outcome of emotional expression and likelihood of expression among 125 first-, fourth-, and sixth-grade children. Results suggest that socialization practices tend to be directed towards the suppression of sadness among males. (RJC)

Causal interpretations of story characters' helpful behavior were examined in first, fourth, and sixth graders, and in college-age students. Subjects heard stories featuring actors' anticipations of eight different consequences for helping. Differences in ratings of actors among age groups were discussed. (Author/CI)
