OBJECTIVE: This study investigated the relationship of interrupted memories of childhood abuse with the secrecy of the abuse. METHODOLOGY: Fifteen hundred people were randomly selected from the membership of the American Counseling Association and sent a questionnaire regarding childhood abuse history. Four hundred and twenty-three usable questionnaires were returned and analyzed. RESULTS: Thirty-two percent of the sample reported childhood abuse. Fifty-two percent of those reporting abuse also noted periods of forgetting some or all of the abuse. On the two survey items assessing secrecy, 76% of respondents reporting childhood abuse indicated there had been a time when no one but themselves and their abuser knew about the abuse; 47% indicated that an abuser tried to get them to keep the abuse secret. Forty percent endorsed both secrecy items. Respondents who reported forgetting abuse also reported one or both elements of secrecy more frequently than those who reported continuous memories of abuse. CONCLUSION: These findings are consistent with those of other studies that suggest that, among adults reporting childhood abuse, the experience of forgetting some or all abuse is common. Secrecy of the abuse appears to be associated with the experience of forgetting childhood abuse for many individuals. 相似文献

Purpose: The purpose of this study was to investigate the physiological adaptations of resistance training (RT) in prepubertal boys. Methods: Eighteen healthy boys were divided into RT (n = 9, Mage = 10.4 ± 0.5 years) and control (CTR; n = 9, Mage = 10.9 ± 0.7 years) groups. The RT group underwent a resistance training during 12 weeks, 3 times per week, performing 3 sets of 6 to 15 repetitions at intensities ranging from 60% to 80% of maximal dynamic strength (1-repetition maximum [1-RM] values). Before and after the training, the groups were assessed in their body mass and composition (dual-energy X-ray absorptiometry), isokinetic dynamometry, 1-RM, and ergoespirometry. Moreover, force per unit of muscle volume was calculated by the quotient between 1-RM and lean mass. Results: Both groups presented statistically significant (p < .05) increases in the 1-RM and force per unit of muscle volume in the knee extension and elbow flexion, but these strength increases were statistically significantly greater in the RT group (effect size [ES] = 2.83–9.00) than in the CTR group (ES = 0.72–1.00). Moreover, both groups statistically significantly increased in lean body mass variables (ES = 0.12–0.38). However, increases in the fat mass variables occurred only in the CTR group (ES = ? 0.01–0.50), whereas no changes were observed in the RT group. Furthermore, there were statistically significant increases in all bone mineral content variables (ES = 0.13–0.43), without differences between groups. No cardiorespiratory changes were observed. Conclusion: Twelve weeks of RT was effective in improving strength and force per unit of muscle volume and prevented fat mass increases in boys. 相似文献

In this essay, Scott Pratt develops the tension at work in Democracy and Education between conceptions of multiculturalism that emerge from Dewey's commitment to progress as a process of civilization and from his contrasting commitment to a vision of progress as a localized process that requires respect for boundaries and limits. The first is related to what Patrick Wolfe has called “settler colonialism.” The second conception of multiculturalism, framed by the aims of education and the conception of growth, avoids the problems of the first and provides a foundation for a practical, decolonial multiculturalism in the context of twenty‐first‐century education. 相似文献

In Tajikistan, infants are bound supine in a “gahvora” cradle that severely restricts movement. Does cradling affect motor development and body growth? In three studies (2013–2018), we investigated associations between time in the gahvora (within days and across age) and motor skills and flattened head dimensions in 8–24-month-old Tajik infants (N = 269, 133 girls, 136 boys)) and 4.3–5.1-year-old children (N = 91, 53 girls, 38 boys). Infants had later motor onset ages relative to World Health Organization standards and pronounced brachycephaly; cradling predicted walk onset age and the proficiency of sitting, crawling, and walking. By 4–5 years, children's motor skills were comparable with US norms. Cultural differences in early experiences offer a unique lens onto developmental processes and equifinality in development. 相似文献

Multiple studies (n = 1065 parents, 625 females, 437 males, 3 nonbinary, 99.06% White; n = 80, 5 to 7-year-old children, 35 girls, 45 boys, 87.50% White; data collection September 2017–January 2021) investigated White U.S. parents' thinking about White children's Black-White racial biases. In Studies 1–3, parents reported that their own and other children would not express racial biases. When predicting children's social preferences for Black and White children (Study 2), parents underestimated their own and other children's racial biases. Reading an article about the nature, prevalence, and consequences of White children's racial biases (Study 3) increased parents' awareness of, concern about, and motivation to address children's biases (relative to a control condition). The findings have implications for engaging White parents to address their children's racial biases. 相似文献

School psychologists have been involved with developing and installing individual contingencies designed to remedy individual students' academic deficits. Group-oriented contingencies can be applied to broader efforts designed to prevent learning problems class-wide. Independent group-oriented rewards are frequently used in school settings to enhance learning by rewarding strong academic performance (e.g., reward for each student who maintains a 90% average). Research suggests overreliance on these contingencies may not be educationally equitable because they may be less effective or ineffective in influencing the behavior and learning of students with weaker academic skills. Theoretical and applied research is analyzed which suggests that maintaining ubiquitous independent rewards and providing supplemental interdependent group-oriented bonus rewards may allow educators to a) maintain their academic standards, b) enhance educational equity by improving learning in students who may not respond to typical independent group-oriented rewards, and c) enhance classroom climates. Also, recommendations are provided that may allow educators to mitigate concerns over perceived unfairness associated with interdependent group-oriented rewards. 相似文献

Faiths have long used education as a means to preserve and transmit cultural values from one generation to the next. However, they have also employed education to unite people of different cultures and proselytise others to their worldview. Over the last two centuries, the Church of Jesus Christ of Latter-day Saints (Latter-day Saint, LDS, or Mormon) has exercised these same patterns in its educational programmes, especially internationally, as it has sought to expand around the world. Using Mormonism's Juárez Academy in northern Mexico as a historical case study, our paper demonstrates how transnationally governed religion-led school systems can confront the challenge of exceptionalism by embracing local culture and customs while maintaining the heritage of their faith tradition. The study advances the field of international education, highlighting the issues of globalisation, cultural transfer, and transnational educational governance. 相似文献

Although researchers in undergraduate science, technology, engineering, and mathematics education are currently using several methods to analyze learning gains from pre- and posttest data, the most commonly used approaches have significant shortcomings. Chief among these is the inability to distinguish whether differences in learning gains are due to the effect of an instructional intervention or to differences in student characteristics when students cannot be assigned to control and treatment groups at random. Using pre- and posttest scores from an introductory biology course, we illustrate how the methods currently in wide use can lead to erroneous conclusions, and how multiple linear regression offers an effective framework for distinguishing the impact of an instructional intervention from the impact of student characteristics on test score gains. In general, we recommend that researchers always use student-level regression models that control for possible differences in student ability and preparation to estimate the effect of any nonrandomized instructional intervention on student performance. 相似文献

This study evaluated the degree to which a range of social emotional learning skills—academic self-efficacy, academic motivation, social connections, importance of school, and managing psychological and emotional distress and academic stress— could be used as an indicator of future academic outcomes. Using a sample of 4,797 from a large urban school district, we found that high school students classified as performing in the lowest 25% of their grade reported lower social emotional skills than students classified in the top 25% of academic performers by the end of the 8th grade. Two variables, perceived importance of attending college and psychological and physical stress, accounted for nearly 26% of the variance in cumulative high school GPA after controlling for 9th-grade GPA. Finally, the results indicated that a combination of 5 social emotional learning subscales effectively discriminated between students making positive progress towards high school graduation and those identified as having dropped out of or failed more than 14% of their courses. 相似文献
