In the current work, we extend the Categorization-Individuation Model (Hugenberg, Young, Bernstein, & Sacco, 2010)—an existing model of the own race bias—to organize and explain the proliferation of own group biases in face memory. In this model, we propose that own group biases result from the coacting processes of social categorization,motivation to individuate, and individuation experience. This extended Categorization-Individuation Model affords a number of benefits. First, this model allows us to begin to consider various own group biases as manifestations a single class of phenomena, offering sensible predictions across and among biases. Further, this extended Categorization-Individuation Model makes novel predictions for how own group biases can be exacerbated and eliminated by both perceptual and motivational processes, allowing for potentially novel interventions forown group biases. Finally,we discuss a variety of open questions with regard to an extended Categorization-Individuation Model, with an eye towards framing future research questions.  相似文献

Service employees' emotional display plays an important role in service interactions, but little is known about the effects of employee's emotional regulation strategies on customer outcomes. This study examines a model in which emotion regulation is associated with customer satisfaction and loyalty intentions as mediated by employee burnout and engagement. Data collected from 135 employee–customer dyads following service interactions was analysed with structural equation modelling. The results show that engagement fully mediates the relationship of deep acting, and burnout partially mediates the relationship of surface acting, with customer satisfaction and loyalty intentions.  相似文献

This study examines whether climate strength has a direct, moderating, or curvilinear effect in the relationship between service climate and customer service quality perceptions. To this end, we carried out cross-sectional and lagged empirical studies in the Spanish hospitality sector. Our cross-sectional results confirmed that high climate strength in managerial practices fosters a positive impact of managerial practices on customer service quality evaluations. However, other results related to customer orientation of services question the idea that service climate strength is always a precursor of service quality. High climate strength in customer orientation enhanced the negative relationship between customer orientation and functional service quality in a cross-sectional study, and between customer orientation and relational service quality in a lagged study. In addition, an examination of curvilinear effects of climate strength revealed an inverted U-shaped relationship between climate strength in customer orientation and relational service quality over time. The article concludes with a discussion of these results.  相似文献

ObjectivesRecent figures indicate that nearly a quarter of Australian adolescents are overweight or obese. Despite the well-established role of physical activity and healthy eating in reducing prevalence of obesity, there remains a lack of effective interventions that promote sustained behavior engagement. This paper aims to describe the theory-based integration and implementation of self-determination theory and goal setting theory in a family-based lifestyle intervention. Although these theories have been shown to independently predict motivation for behavior, a limited number of studies have described behavior-change techniques at a level to allow for effective evaluation and replication, and no studies have combined the theories in a healthy lifestyle behavior intervention.MethodsBehavior change techniques and the associated change mediators are described in relation to need-supportive environments provided by instructors and extended to parents in the home environment. Methods for motivating and promoting sustained engagement in adolescent physical activity and healthy eating and parent behaviors to support these lifestyle changes are discussed within the context of need-satisfaction and goal setting.ConclusionsThis study will contribute to understanding processes for developing and implementing behavior-change techniques based on the integration of two theories of motivation. Future interventions aimed at promoting maintenance of physical activity and healthy eating behaviors in overweight and obese adolescents will benefit by being informed of which techniques are effective at enhancing motivation within the intervention context and home environment.  相似文献

Federal bureaucrats are important sources of information about policy problems. However, federal officials compete for this influence with organized interests plying their own problems and solutions. We attribute the differential agenda influence of the federal bureaucracy to efforts in Congress to construct workable problem definitions in a context of uncertainty about issues. From both behavioral and rational models of congressional decision making, we develop a theory of congressional search for information during problem definition under conditions of uncertainty. The theory presages the prominence of federal bureaucrats in this search, and especially under uncertainty. Using new data sets capturing the appearance of federal bureaucrats at congressional hearings, we find that the mobilization, prominence, and types of federal bureaucrats providing information is explainable in terms of congressional uncertainty about problem definitions.  相似文献

ObjectivesThe aim of this study was to examine age- and gender-related patterns of PA and depressive symptoms among students through their adolescent years.DesignData from three population-based surveys were analysed to determine levels of moderate- to vigorous-intensity PA (MVPA), participation in organized sports and depressive symptoms among 10−19-year-old adolescents.MethodQuestionnaires assessing PA and depressive symptoms were administered to 32 860 students in compulsory and upper-secondary schools in Iceland.ResultsAs age increased, depressive symptoms increased and PA decreased with over half of the adolescents in upper-secondary schools not achieving recommended daily PA. There were gender differences in PA and depressive symptoms with girls being less active and reporting higher levels of depressive symptoms than boys. MVPA was associated with lower levels of depressive symptoms among both genders while organized sports had more impact on depressive symptoms among girls.ConclusionsTo our knowledge, this study is the first to simultaneously examine patterns of PA and depressive symptoms among students through their adolescent years. Our findings show that the decrease in PA and increase in depressive symptoms is most pronounced around the transition from compulsory to upper-secondary school, or around the age of 15–16. Thus the findings provide important information about when to tailor public health efforts to reduce the burden of depressive symptoms among adolescents, for example by employing PA interventions.  相似文献

To investigate children’s theories of motivation, we asked 166 children (8-12 years of age) to rate the effect of various motivational strategies on task interest, over the short and long terms, in activities described as appealing or unappealing. Children viewed the rewards strategy as resulting in greatest interest except when implemented over the long term for appealing activities. Individual difference analyses revealed that some children held operant theories of motivation, in which rewards were central, and others held hybrid theories, in which rewards were key, but some allowance was made for interest to be self-sustaining in the absence of inducements. Children’s theories predicted their academic self-regulation. Their theories are discussed relative to an expert theory of motivation.  相似文献

In two experiments, ostracized individuals showed more pronounced categorical perception of inclusion- and exclusion-related stimuli. Specifically, ostracism enhanced the ability to distinguish between-category differences (e.g., between happy and angry faces) relative to within-category differences (e.g., between two happy expressions). Participants were socially included or excluded via Cyberball (a virtual ball-tossing task). In Experiment 1, ostracized participants showed greater perceptual acuity in distinguishing between subtly happy and angry expressions combined with a reduced ability to discriminate expressions within each expression category. Experiment 2 found analogous categorical perception effects for targets varying on the dimension of race. Importantly, this effect was specific to social information; categorical perception of non-social objects was not qualified by social exclusion. These results suggest that ostracism exacerbates categorical perception, attuning perceivers to the differences between various inclusion- and exclusion-related categories relative to within category acuity, making the world appear more ‘black-and-white’ than it might otherwise.  相似文献
