The purpose of this study was to examine whether dispositional sadness predicted children's prosocial behavior and if sympathy mediated this relation. Constructs were measured when children (n = 256 at time 1) were 18, 30, and 42 months old. Mothers and non‐parental caregivers rated children's sadness; mothers, caregivers, and fathers rated children's prosocial behavior; sympathy (concern and hypothesis testing) and prosocial behavior (indirect and direct, as well as verbal at older ages) were assessed with a task in which the experimenter feigned injury. In a panel path analysis, 30‐month dispositional sadness predicted marginally higher 42‐month sympathy; in addition, 30‐month sympathy predicted 42‐month sadness. Moreover, when controlling for prior levels of prosocial behavior, 30‐month sympathy significantly predicted reported and observed prosocial behavior at 42 months. Sympathy did not mediate the relation between sadness and prosocial behavior (either reported or observed).  相似文献

High‐quality developmental science requires a reliable and representative stream of participants, yet recruiting infants at a satisfactory rate can be challenging. We recently developed a new recruitment technique: we invite parents to sign up for no‐strings‐attached playdates in our laboratory, where we provide toys, free coffee, and students to help entertain the children. We have consistently hosted 2–3 new parents per week via playdates. Approximately 88% of attending parents agreed to be contacted later about research, and 81% of those contacted returned for research appointments. This method has doubled the number of participants we run per week, improved our rapport with the local community, and provided an enhanced educational opportunity for students in our laboratory. We hope others find it similarly transformative.  相似文献

The investigation of two historically isolated communities in the United States, Smith Island, Maryland, and the Lumbee Native American community in Robeson County, North Carolina, demonstrates that, contrary to assumption, isolated communities may be linguistically innovative and heterogeneous. Explanations are both cognitive and social. Speakers in isolated communities are not subject to the leveling pressure that comes with exposure to heterogeneous usage norms and so are free to retain intra-dialectal variation and carry through internal innovations. In addition, the close-knit networks that characterize isolated communities allow for the transmission of intricate patterns of intra-community variation, while the inward focus of such communities heightens the social semiotic importance of this variation. The present study also shows that as communities emerge from historic isolation, they do not necessarily succumb to leveling pressure. Instead, speakers' desire to retain cultural distinctiveness may enable them to retain and even enhance their linguistic distinctiveness.  相似文献

Physical activity may promote cognitive health in older adults. Popular media play an important role in preventive health communication. This study examined articles discussing associations between physical activity and cognitive health in top-circulating magazines targeting older adults. 42,753 pages of magazines published from 2006 to 2008 were reviewed; 26 articles met inclusion criteria. Explanations regarding the link between physical activity and cognitive health were provided in 57.7% of articles. These explanations were generally consistent with empirical evidence; however, few articles included empirical evidence. Physical activity recommendations were presented in 80.8% of articles; a wide range was recommended (90-300 min of physical activity per wk). Socioeconomic status and education level were not mentioned in the text. Results suggest an opportunity for greater coverage regarding the role of physical activity in promoting cognitive health in popular media. Magazine content would benefit from including more empirical evidence, culturally sensitive content, and physical activity recommendations that are consistent with U.S. guidelines.  相似文献

Among the more profound features of population ageing is its regionality. This regionality is particularly marked in Australia, where the timing and speed of ageing are occurring at substantially different rates by state and territory. The shift to natural decline is expected to create many social, economic and political predicaments where it is first experienced. In Australia, Tasmania will be the first to enter natural decline, followed soon thereafter by South Australia, but not for several years by the youngest states and territories. These diverging demographic forces will have many implications for the complex mixture of federal, state and local government that currently adjudicates over policy-making and implementation, especially concerning the collection of taxes, the distribution of the goods and services of the Welfare State, and a large element of fiscal redistribution. This paper provides an overview of demographic characteristics and dynamics by region, and examines their projected effects on three socio-economic indicators: educational demand, the labour market, and demand for Age Pensions. The changing demography will have both beneficial and adverse affects, and unless the profound regionality is soon understood and engaged with, currently older and younger states are likely to encounter not only diverging demographic forces, but also diverging fortunes.  相似文献

Objective. This article examines panethnic consciousness as it applies to the two fastest‐growing minority groups in the United States: Asian Americans and Latinos. Given the challenges of diversity and immigration faced by these two communities, I examine the individual‐level factors that help strengthen their panethnic group identity. Methods. Drawing from data provided by the 2000 Pilot National Asian American Political Survey and the 1999 National Survey on Latinos, I use ordered probit models to determine the predictors of panethnic consciousness among both Asian Americans and Latinos. Results. The models confirm that for Asian Americans, high income, involvement in Asian‐American politics, being a Democrat, and the role of racial discrimination encourage panethnic consciousness. For Latinos, the important factors are higher levels of education, gender, being foreign born, involvement in Latino politics, and perceptions of discrimination. Conclusions. The findings here stress the importance of social contextual factors such as racial discrimination on the formation of panethnic identity.  相似文献
