Social skill in third and sixth grade children: A moderator of lifetime stressful life events and behavior problems?

We investigated relationships among stressful lifetime life events, social skill, and behavior problems in children. Participants were 159 third graders, 138 sixth graders, and their mothers. Mothers reported on their children's life events, social skill, and behavior problems. Children self-reported on their social skill and behavior problems. Increased numbers of stressful life events significantly predicted increased behavior problems in third and sixth graders. Increased social skill significantly predicted decreased behavior problems in third and sixth graders. Social skill served a stress-protective role for third but not sixth graders; third graders with increased life events and better social skill had fewer behavior problems than their less socially skilled peers. Practical and theoretical implications are discussed, and suggestions for future resilience research are presented.     

Social sharing of emotional experiences in Asian American and European American women

The present study investigated the relationships among ethnicity and social sharing of traumatic experiences in a sample of 88 East Asian and 88 European American women. Participants were asked to write about a traumatic experience for twenty minutes and then to rate how upsetting the experience was, how often they thought about it, how often and to whom they had previously disclosed the experience, as well as the perceived appropriateness of sharing the experience with different target audiences, e.g., friends and family members. The results indicated that Asian Americans reported speaking to others less frequently about the traumatic event and sharing it with fewer individuals, and tended to be more likely to share the event with friends than with family members when compared to European Americans. Asian Americans also reported thinking about the upsetting event less frequently than European Americans even though both groups reported that the events were equally upsetting. The more upsetting events were, the more often they were shared in the European American group, but there was no relationship between how upsetting events were and the degree to which they were shared in the Asian American group.     

4~8年级学生分数数量表征的准确性及形式

在分数学习中,分数数量表征是非常重要的方面。本研究利用数字线估计任务对四到八年级学生分数数量表征的情况进行探索。研究结果表明：随着年级升高,被试分数数量表征的准确性也随之提高;被试对单位分数和非单位分数表征的准确性存在显著差异,表现为对单位分数表征的准确性显著高于对非单位分数的表征,这种差异在低年级显著,随着年级的增长,差异逐渐消失;四到八年级学生在0~3数字线上,对分数数量的表征表现为线性形式而非对数形式,且这种线性表征形式是在六年级开始出现并随着年龄增长逐渐发展起来的。中西方儿童在分数数量表征的准确性和形式上有相似的发展路径,但是在表征准确性上中国儿童更高、线性形式出现年级上中国儿童可能更早。

Adults' memories of childhood: Affect,knowing, and remembering

Adult questionnaire respondents reported, for each of a number of events, if they had experienced that event during childhood and, if so, if they remembered the experience or merely knew it had happened. Respondents also rated the emotion of each event and judged whether they would remember more about each reportedly experienced event if they spent more time trying to do so. Study 1 respondents were 96 undergraduates, whereas Study 2 tested 93 community members ranging widely in age. Respondents often reported no recollections of reportedly experienced events. Reportedly experienced events rated as emotional were more often recollected than those rated as neutral, and those rated as positive were more often recollected than those rated as negative. Predicted ability to remember more was related to current memory. Claims of remembering reportedly experienced events increased with age, but predicted ability to remember more about them declined with age.

CPQ personality factors of upper elementary gifted students

The results of administering the Children's Personality Questionnaire (CPQ) to gifted students in the fourth, fifth, and sixth grades indicated that they had personality profiles similar to the norm group. Gifted males were more controlled, socially precise, self-disciplined, and compulsive than females, described as more casual and careless of social rules. Also, gifted females were more assertive and independent than males who had scores suggesting a more obedient, mild, or conforming personality. In comparing personality factors across grades, fourth graders had profiles significantly different from sixth graders.     

An experimental study of the physical and psychological effects of aerobic exercise on schoolchildren

This study compared the physical and psychological effects of running to those of the normal physical education program of activities among 154 fourth, fifth, and sixth graders who were randomly assigned to conditions within a true experimental design. The running program consisted of three 30-min sessions per week for 12 weeks in lieu of attendance in regular physical education classes. Findings showed that although boys tended to run faster than girls overall and that older children run faster than younger children, running-program participants performed better on an 800-m run, had lower pulse rates, and performed better on a test of creativity than did regular physical education participants. Running boys had less body fat, and running girls had more creative involvement in class. No differences were found on 50-m dash performance or perceptual skill. On total behavior, girls were more self-controlled than boys, and self-concept tended to become less positive with increased grade level. Running performance for 800 m persisted for 5 months among boys in the treatment, but not among girls. Running was judged effective for enhancing the cardiorespiratory health and creativity of school children.     

Generating keywords improves metacomprehension and self-regulation in elementary and middle school children

The ability to monitor understanding of texts, usually referred to as metacomprehension accuracy, is typically quite poor in adult learners; however, recently interventions have been developed to improve accuracy. In two experiments, we evaluated whether generating delayed keywords prior to judging comprehension improved metacomprehension accuracy for children. For sixth and seventh graders, metacomprehension accuracy was greater when generating keywords. By contrast, for fourth graders, metacomprehension accuracy did not differ across conditions. Improved metacomprehension accuracy led to improved regulation of study. The delayed keyword effect in children reported here is discussed in terms of situation model activation.     

Children can solve Bayesian problems: the role of representation in mental computation

Can children reason the Bayesian way? We argue that the answer to this question depends on how numbers are represented, because a representation can do part of the computation. We test, for the first time, whether Bayesian reasoning can be elicited in children by means of natural frequencies. We show that when information was presented to fourth, fifth, and sixth graders in terms of probabilities, their ability to estimate the Bayesian posterior probability was zero. Yet when the same information was presented in natural frequencies, Bayesian reasoning showed a steady increase from fourth to sixth grade, reaching an average level of 19, 39, and 53%, respectively, in two studies. Sixth graders' performance with natural frequencies matched the performance of adults with probabilities. But this general increase was accompanied by striking individual differences. More than half of the sixth graders solved most or all problems, whereas one third could not solve a single one. An analysis of the children's responses provides evidence for the use of three non-Bayesian strategies. These follow an overlapping wave model of development and continue to be observed in the minds of adults. More so than adults' probabilistic reasoning, children's reasoning depends on a proper representation of information.     

On the Meaning of Time in Later Life

Fourth-, sixth-, and eighth-grade subjects participated in a free-recall experiment to test the relative power of two Taxonomic, two Semantic Differential, and two Sense Impression word classes in facilitating recall. Findings show that across all grades children exhibited a significantly greater tendency to recall and cluster Taxonomic and Semantic Differential over Sense Impression word classes. Further, sixth and eighth graders recalled more words over all word classes than fourth graders. It was also found that girls recalled more words than boys across all three grade levels and all six word classes. Finally, there was no grade or sex effect for clustering. An interpretation of this difference was offered     

Parental preferences regarding sex education topics for sixth graders

The purpose of this study was to ascertain which sex education topics parents of preadolescents regarded as appropriate for their children. The sample was comprised of 146 respondents randomly selected from a class list of sixth graders in a suburban school district. A mailed, self-administered questionnaire listing 48 possible topics was used to elicit parental response. Pretesting found the questionnaire to be highly reliable (Cronbach's alpha = .95). Overall, parents strongly supported the inclusion of a broad range of sex education topics regardless of parental age, sex, marital status, income, education, or child's sex. Moreover, parents were largely in agreement with the inclusion of sensitive topics in addition to those which were more physiological or behavioral. Catholics more often than Protestants agreed with the inclusion of birth control, abortion, and sterilization even after controlling for income and education. Thus, the findings suggest that parents of sixth graders find a broad sex education program in the school appropriate. To this end, school officials and sex educators should not overlook the needs of preadolescents for sex education solely on the basis of perceived parental opposition.     

World Reconstruction and the Concept of Distribution of Mental Abilities in Races,Nations, and Social Strata

Summary

This study represents an attempt to study the development of situational causality among preadolescents in four diverse cultures. The subjects were 320 children, 80 each in India, Western Samoa, Mexico, and the United States (Metropolitan Atlanta, Georgia), divided equally between the fourth and sixth grades and advantaged and disadvantaged backgrounds. The subjects' responses to the Guess Causes task of the Torrance Tests of Creative Thinking were scored for causality. Comparisons were made on the basis of both number of responses and proportion of responses for cultures, grade levels, and advantageness of socioeconomic background. In general, children in India and the United States were more causally oriented than their counterparts in Mexico and Western Samoa. The sixth-grade children tended to be more causally oriented than the fourth graders, and the advantaged children were more causally oriented than their more disadvantaged counterparts. There were a number of statistically significant interactions for grade by culture, however, indicating that developmental trends are modified by cultural forces.     

Reward and number of choices in children's probability learning: An attempt to reconcile conflicting findings

Five event schedules (75:0, 75:25, 75:0:0, 72:25:0, 75:12.5:12.5) were examined in a size discrimination task with penny rewards and plastic token markers. The subjects were 100 fourth graders (mean age = 9.4 years) and 100 undergraduates of both sexes. Whether or not the event probabilities summed to unity proved to be a more important determiner of terminal performance than the number of response alternatives in the task (p < .01). Females maximized more than males (p < .001) and college students more than fourth graders (p < .001). Greater maximization was exhibited by fourth graders in the reward condition (p < .01). These reward effects appeared to be more consistent with a detrimental-effects-of-reward interpretation than either utility or expectancy interpretations.     

The Impact of Implicit Self-Theory on Rated Creativity in Third- and Sixth-Graders

A total of 114 3rd- and 6th-graders from a suburban elementary school participated in a study examining the influence of implicit self-theories on rated creativity in the domains of art and literature in a quasi-experiment. Creativity was measured via the Consensual Assessment Technique. Participants were divided into two groups and received different sets of instructions emphasizing either an incremental or entity-implicit theory of creativity, before completing a drawing task and a writing task. Implicit theories of creativity of participants were measured before and after the instructions were given. The results indicated that participants in the incremental group showed increased incremental views following the manipulation; participants in the entity group showed no significant change. The writing (but not the artwork) from the incremental group was rated as more creative than those from the entity group. This effect was stronger for third graders than for sixth graders, suggesting that implicit theory interventions are more effective with younger children. Implications are discussed.     

Effects of Feedback on Self‐Evaluations and Self‐Regulation in Elementary School

Elementary school learners are typically highly confident when judging accuracy of their test responses, relatively independent of whether these are correct. While feedback has been shown to improve accuracy of adults' and adolescents' self‐evaluations and subsequent self‐regulation, little is known about beneficial effects for elementary school children. We investigated effects of fine‐grained feedback on fourth and sixth graders' self‐evaluations and restudy selections by presenting them the ideas they were meant to bring up in their test responses. One group received full‐definition feedback standards, whereas the other group received idea‐unit feedback standards. The two types of feedback strongly improved fourth and sixth graders' self‐evaluations for commission errors and for partially correct responses. While restudy selections before feedback were more adaptive for sixth than fourth graders, age differences disappeared after receiving feedback. Findings imply that feedback standards are a suitable tool to calibrate elementary school learners and to support effective self‐regulation.Copyright © 2017 John Wiley & Sons, Ltd.     

Changes in the semantic constraint of spreading activation of memory across three age groups

28 undergraduate, 34 sixth-grade, and 36 second-grade students studied target words embedded in interchangeable or noninterchangeable sentences, and then performed free recall tests. In an interchangeable sentence the word which was to be remembered and its associated word fitted sensibly, whereas in a noninterchangeable sentence the target word fitted sensibly but its word associate did not. Undergraduates recalled the target words in noninterchangeable sentences better than sixth or second graders for whom a difference was not observed (undergraduates > sixth graders = second graders). In interchangeable sentences undergraduates recalled more targets than sixth or second graders, and sixth graders recalled more than second graders (undergraduates > sixth graders > second graders). The results were interpreted as indicating changes across age groups in the semantic constraint of spreading activation of target words in memory.
