Generativity and authoritarianism assessed at age 52 were correlated with criterion variables assessed at age 62 in a sample of well-educated women (N = 81). Results indicated that generativity predicted positive personality characteristics, satisfaction with marriage and motherhood, and successful aging. By contrast, although authoritarianism is linked in the literature to endorsing traditional gender roles, authoritarianism was uncorrelated in the current study with happiness about marriage and was negatively related to perceptions of motherhood. Furthermore, authoritarianism was correlated with neuroticism later in life. These data suggest that midlife authoritarianism may be problematic as women transition from their 50s to their 60s. Midlife generativity, in contrast, seems to offer one path to life satisfaction.  相似文献

Despite knowledge of early pathways to conduct problems, few preventive interventions are specifically designed to modify disruptive behavior in toddlerhood. One potential prevention target is proactive and positive parenting, which is associated with reduced risk of conduct problems in preschoolers. This randomized trial with 120 low-income 2-year-old boys examined whether a brief family-centered intervention that reduces disruptive behavior (D. Shaw, T. Dishion, L. Supplee, F. Gardner, & K. Arnds, 2006) also leads to increases in proactive and positive parenting. It also explored whether change in parenting predicts change in disruptive behavior. In the intervention group, proactive and positive parenting skills increased among parents of 3-year-olds. Change in proactive and positive parenting of 2- to 3-year-old toddlers correlated with change in child disruptive behavior, although the mediation effect of positive parenting was of only borderline significance. Findings suggest that even within a brief and multifaceted preventive intervention, change in proactive parenting skills contributes modestly but significantly to change in child problem behavior.  相似文献

Research suggests it is important for students to feel a sense of belonging to their school. Students who do not belong at school often attempt to satisfy this need through membership in antisocial groups, or they drop out from school altogether. The current study explored the perceptions and experiences of the school context held by young people who have left school early. Twelve young people aged 16–19 years were interviewed on their experiences of school and their wellbeing as a result of leaving school early. Constructionist grounded theory methodology formed the basis of the data analysis. The early leaving process was identified as having three phases; exclusion from school, the transition into workforce and the ‘now’ phase. The results identified factors in the school context that contributed to early student withdrawal. Furthermore, the research has implications for creating a ‘normative narrative’ (Rappaport, 2000 ) in relation to early school leavers. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

Test stimuli are rated as less “good” when they follow very good context stimuli than when they are presented alone. This diminution in rating is called hedonic contrast. Contrast is attenuated if the context and the test stimuli are perceived as being in different categories. Because experts use as their basic-level categories what are the subordinate levels for novices, they will categorize when novices do not. Therefore, in the following studies, both experts and novices showed hedonic contrast when attractive context orchids preceded more neutral test orchids. However, only the novices showed hedonic contrast when attractive context irises preceded the test orchids. Novices viewed the irises and the orchids as “flowers” and therefore members of the same category, resulting in contrast. Experts, however, viewed the irises and the orchids as being in different categories; therefore, hedonic contrast did not occur.  相似文献

HomeNetToo is a longitudinal field study designed to examine the antecedents and consequences of home Internet use in low-income families. Participants included 140 children, mostly 13-year-old African American (83%) boys (58%), living in single-parent households (75%) where the median annual income was $15,000 (USD). This report focuses on children's Internet activities, socio-demographic characteristics related to their Internet activities, and the relationship between academic performance and Internet activities. Overall, findings indicate that low-income children initially use the Internet primarily for entertainment. As home Internet use loses its novelty children become more focused in their Internet activities, reducing the number of websites they visit and visiting more websites targeted to their specific interests. Pornography websites are popular initially, especially among boys, but their popularity decreases dramatically after 3 months. Age, race, and sex have little influence on which websites are most popular. Academic performance predicts subsequent Internet activities, and Internet activities predict subsequent academic performance. Directions for future research to identify mechanisms that mediate the relationship between Internet activities and academic performance and implications for the digital divide are discussed.  相似文献

We examined the effects of a person factor (general causality orientation) and an environment factor (threat of evaluation) on creativity and personal experience of a creative collage-making task. Ninety college students completed questionnaires and made a collage under conditions of expected evaluation or no-evaluation. Creativity was a function of participants’ characterizations of themselves as artistic, and among men, of the interaction between environment and person factors. Task experience was affected by environment factors and, marginally, by the interaction of environment and person factors, with participants feeling less competent at the task under threat of evaluation, and exerting the greatest effort when they were under evaluation threat and were higher on control orientation. These findings may have implications for future motivation for creative tasks.  相似文献

Two experiments assessed the self-protective and undermining effects of attributional ambiguity. Both studies utilized immersive virtual environment technology to achieve otherwise difficult manipulations of stigma. In Experiment 1, White and Latino participants were either stigmatized (represented as Latino) or not (represented as White) and given negative leadership performance feedback. Afterwards, stigmatized participants reported higher well-being and attributed negative feedback more to discrimination than nonstigmatized participants. In Experiment 2, Latinos represented veridically showed self-protective effects after receiving negative leadership feedback. Additionally, this experiment revealed undermining effects of attributional ambiguity such that those participants represented as Latino discounted positive feedback and reported lower well-being. Thus, attributional ambiguity of stigmatized individuals (real or induced) buffered well-being in the face of negative feedback but undermined the well-being effects of positive feedback.  相似文献

Risk factors for suicidal ideation and attempts have been shown to differ between African Americans and Whites across the lifespan. In the present study, risk factors for suicidality were examined separately by race/ethnicity in a population of 131 older adult patients considered vulnerable to suicide due to substance abuse and/or medical frailty. In adjusted analyses, social support was significantly associated with suicidality in African American patients, while younger age and the presence of an anxiety disorder were significantly associated with suicidality in White patients. The results suggest that race/ethnicity-specific risk profiles may improve the detection of suicidality in vulnerable populations.  相似文献

ABSTRACT— For almost 5 decades, the scientific study of emotion has been guided by the assumption that categories such as anger, sadness, and fear cut nature at its joints. Barrett (2006a) provided a comprehensive review of the empirical evidence from the study of emotion in humans and concluded that this assumption has outlived its usefulness. Panksepp and Izard have written lengthy papers (published in this issue) containing complementary but largely nonoverlapping criticisms of Barrett (2006a) . In our response, we address three of their concerns. First, we discuss the value of correlational versus experimental studies for evaluating the natural-kind model of emotion and refute the claim that the evidence offered in Barrett (2006a) was merely correlational. Second, we take up the issue of whether or not there is evidence for "coherently organized neural circuits" for natural kinds of emotions in the mammalian brain and counter the claim that Barrett (2006a) ignored crucial evidence for existence of discrete emotions as natural kinds. Third, we address Panksepp and Izard's misconceptions of an alternative view, the conceptual act model of emotion, that was briefly discussed in Barrett (2006a) . Finally, we end the article with some thoughts on how to move the scientific study of emotion beyond the debate over whether or not emotions are natural kinds.  相似文献

Why are there so many people who receive scholarship aid who do not give back to the schools that gave it? Social exchange theories grounded in the assumption of direct reciprocity have long been the framework used within higher education to understand donative behavior. As a result, conventional wisdom within higher education holds that recipients of scholarship aid will later donate money to the institution that provided it. However, the philanthropic data show that most aid recipients do not, in fact, give back. This study probes the underlying factors for this phenomenon by using the Listening Guide, a voice-centered relational method of discovery, to analyze and interpret interviews with 10 scholarship recipients. By providing a more robust understanding of the experience of receiving, the findings challenge some of the most basic psychological and sociological assumptions about giving and generosity within higher education.  相似文献
