In the United States, the long-term effects of early childhood programs have been given particular weight in research on early childhood education and in policy debates about the value of prekindergarten. Many research teams were building the evidence base on U.S. early childhood programs to inform that discussion when studies were upended by the COVID-19 pandemic. In this article, we describe the theoretical and practical risks the COVID-19 pandemic poses for longitudinal studies of preschool intervention programs. We also discuss the potential opportunities the crisis offers by introducing new variation in postprogram experiences for addressing new questions. The article intersects the resilience and disaster literatures with theoretical frameworks for the persistence of preschool effects. We conclude with recommendations for how longitudinal studies of cohorts affected by COVID-19 can enhance our understanding of the mechanisms behind the persistence of preschool effects.  相似文献

Within a pre-post-design, we scrutinized the effects of normative augmented feedback with positive and negative valence on learning motor accuracy, consistency as well as automaticity by means of a dual-task paradigm. Forty-two healthy physical education students were instructed to produce an arm-movement sequence as precisely as possible with regard to three spatial reversal points within a time limit of 1200 ms. Twenty-eight practiced an elbow-extension-flexion-sequence (690 trials) and 14 participants were tested as a control group without feedback practice. Valence of normative feedback was systematically manipulated by means of reference lines in a visual feedback display. The reference lines indicated performance of a putative peer-group either to be superior (negative valence, Normative-Negative-Group) or inferior (positive valence, Normative-Positive-Group) to participants’ actual performance.As a result, dual-task costs (n-back error) significantly decreased solely in the Normative-Positive-Group, p = .003, η2p = .51, but in no other group. Surprisingly, the mean absolute error for the motor task significantly decreased (i.e., precision increased) only in the Normative-Negative-Group with a large effect size, but in none of the other groups. Motor consistency was not significantly affected by the valence of normative feedback. According to the hypotheses of error-provoked attentional control, positive feedback-valence appears to enhance skill automatization, while – unexpectedly – only negative feedback-valence seems to enhance movement precision, which may be explained by effects of feedback valence on the learners aspiration level.  相似文献

This article introduces stories as a link between culture and evolution. It elaborates how the decline of interhuman communication leads to a loss of perception, capability for cooperation, and human intelligence and contributes to the current ecocide. It shows how cybernetics hacked the relationship between evolution and machine development, which brought forth the outlines of man’s current digital transformation and future. It suggests that Lucas Pawlik is still working on a possible sustainable future for humanity that Heinz von Foerster tried to initiate.  相似文献

This meta‐analysis investigated the efficacy of interventions aimed at reducing procrastination in randomized controlled trials. Twelve studies, with a total of 646 participants, met inclusion criteria. The significant meta‐analytic effect size, Hedges's g = 1.18, indicates that the interventions had a large positive effect. Three variables significantly moderated effect size: Higher effects were associated with interventions delivered in person, student samples, and a no‐treatment control condition. The results lay a foundation for procrastination treatment and future research.  相似文献

Human Library is a public event aimed at reducing stereotypes and prejudices, in the form of an interactive, contact‐based intervention. It employs the logic of a regular library yet with readers “borrowing” Living Books, which are real people representing various minority groups. Readers engage in 30‐min conversations, during which they can challenge their stereotypes and widen their scope of knowledge and understanding. This pre‐post intervention study examined the effectiveness of the Human Library (held in Wroc?aw, Poland) in reducing social distance towards Roma, Muslims, dark‐skinned, and transgender people, as well as in decreasing homonegativity. Also, we measured whether participation in the Human Library changes individual attitudes towards diverse workgroups. We found that the Human Library decreased social distance towards Muslims. Also, the more Living Books that the participants “read,” the bigger the shift in their social distance towards Muslims. Furthermore, we observed an increase in positive affective attitude towards working in diversified groups, as a result of participation in the event. The study serves as partial support for the effectiveness of the Human Library in altering one's attitude towards minority groups and diversity. The intervention is discussed as a promising but not yet entirely understood tool to improve intergroup relations.  相似文献

Young children who attend out‐of‐home care (e.g., preschool) are more susceptible to infections than children who do not attend out‐of‐home care. Previous research suggests handwashing is effective in reducing risk of infection and illness. However, research suggests that individuals do not routinely wash their hands using methods that healthcare agencies, such as the Centers for Disease Control and Prevention, have determined best practice. We evaluated the effects of a multicomponent handwashing intervention package on correct handwashing across groups of preschool children. Furthermore, we measured the degree to which their hands were clean using premeasures and postmeasures. Results suggest the intervention package was effective at increasing both correct handwashing and cleanliness of participants' hands.  相似文献

ABSTRACT

Marital sexual violence is a serious problem in India. However, marital rape and most other forms of marital sexual violence are not criminalized in the country. This qualitative study with healthcare providers (physicians and nurses), lawyers, members of a non-profit organization that offers domestic violence support services out of a hospital, a journalist and two lawyers suggest that the majority of care providers recognize that marital sexual violence is a serious concern, and agree that health systems can play a vital role in addressing both the immediate biomedical concerns of survivors, and also overall well-being. The study reveals several systemic and internal factors that hinder responsiveness of Indian health institutions. These include, the absence of a protocol or uniform internal guidelines in most hospitals, a lack of screening programs to capture the presence of violence occurring when patients visit hospitals for other reasons, a large patient load, a lack of gender sensitivity in providers’ education, an absence of domestic violence shelters, and poor interlinkages between support services such as counseling and legal services. Notwithstanding these challenges, some exemplar physicians and nurses assist survivors of sexual violence, sometimes risking their own safety. The Indian health system can be made more responsive, provided these factors are addressed, and crucially budgets are allocated for interventions.  相似文献

When multisource feedback instruments, for example, 360-degree feedback tools, are validated, multilevel structural equation models are the method of choice to quantify the amount of reliability as well as convergent and discriminant validity. A non-standard multilevel structural equation model that incorporates self-ratings (level-2 variables) and others’ ratings from different additional perspectives (level-1 variables), for example, peers and subordinates, has recently been presented. In a Monte Carlo simulation study, we determine the minimal required sample sizes for this model. Model parameters are accurately estimated even with the smallest simulated sample size of 100 self-ratings and two ratings of peers and of subordinates. The precise estimation of standard errors necessitates sample sizes of 400 self-ratings or at least four ratings of peers and subordinates. However, if sample sizes are smaller, mainly standard errors concerning common method factors are biased. Interestingly, there are trade-off effects between the sample sizes of self-ratings and others’ ratings in their effect on estimation bias. The degree of convergent and discriminant validity has no effect on the accuracy of model estimates. The χ2 test statistic does not follow the expected distribution. Therefore, we suggest using a corrected level-specific standardized root mean square residual to analyse model fit and conclude with further recommendations for applied organizational research.  相似文献

Job search represents a dynamic process through which job seekers must consistently engage in effective self-regulation. Although scholars have increasingly begun to theorize and conceptualize the job search in this manner, little is known about what fosters effective self-regulation week-to-week. In light of this theoretical gap, we integrate self-regulation theory with the feedback literature to examine how feedback quality influences affective, cognitive, and behavioral regulatory processes in job search. Furthermore, we examine feedback self-efficacy (i.e., how efficacious a job seeker feels with respect to processing and implementing feedback received during the job search) as a stable, person-level moderator of these within-person relationships. In a sample of job seekers surveyed once a week for seven weeks, results indicate that receiving high-quality feedback has a direct influence on positive and negative affective reactions tied to the job search, influencing subsequent positive (i.e., metacognitive strategies) and negative (i.e., affective rumination) cognitive processes. Metacognitive strategies, in turn, impact both the number of résumés sent and hours spent job seeking each week. Moreover, lower feedback self-efficacy amplifies the relationship between feedback quality and negative affective reactions. Our results highlight the importance of high-quality feedback in helping job seekers effectively regulate week-to-week.  相似文献
