A substantial body of empirical evidence suggests that social relationships buffer people from poor health. We review a program of research demonstrating how interpersonal goals create relationship processes that shape the quality of close relationships, which we argue may have consequences for own and others’ health. Self‐image goals to construct, maintain, and defend desired images of the self create negative interpersonal dynamics that undermine close relationships and mental health, while compassionate goals to support others’ well‐being create positive interpersonal dynamics that promote close relationships and mental health. We discuss the potential implications of social goals and close relationship processes for health. Finally, we suggest that exploring the independent benefits of giving and receiving in close relationships may inform how social relationships affect health and well‐being.  相似文献

We tested Ariely's (2001) proposal that the visual system represents the overall statistical properties of sets of objects against alternative accounts of rapid averaging involving sub-sampling strategies. In four experiments, observers could rapidly extract the mean size of a set of circles presented in an RSVP sequence, but could not reliably identify individual members. Experiment 1 contrasted performance on a member identification task with performance on a mean judgment task, and showed that the tasks could be dissociated based on whether the test probe was presented before or after the sequence, suggesting that member identification and mean judgment are subserved by different mechanisms. In Experiment 2, we confirmed that when given a choice between a probe corresponding to the mean size of the set and a foil corresponding to the mean of the smallest and largest items only, the former is preferred to the latter, even when observers are explicitly instructed to average only the smallest and largest items. Experiment 3 showed that a test item corresponding to the mean size of the set could be reliably discriminated from a foil but the largest item in the set, differing by an equivalent amount, could not. In Experiment 4, observers rejected test items dissimilar to the mean size of the set in a member identification task, favoring test items that corresponded to the mean of the set over items that were actually shown. These findings suggest that mean representation is accomplished without explicitly encoding individual items.  相似文献

The changing natures of both work and the lives of the U.S. workforce have created an array of challenges for organizations attempting to foster work engagement. To accommodate the work and family needs of an increasingly diverse workforce, many firms are offering flexible work solutions to employees. However, the distribution of these types of organizational resources is unequal, with workers in lower-wage hourly jobs having the least access to any form of flexibility. The purpose of this paper is to examine the relationship of schedule control, as a form of flexible work practice, and work engagement among workers employed in hourly retail jobs. Authors tested a model whereby the relationship between schedule control and work engagement is mediated by schedule satisfaction and perceived supervisor support. A sample of 1343 full-time hourly retail workers was used to address the study's purpose. Hypothesized relationships were fully or partially supported. Implications for research and practice are discussed.  相似文献

Human behavior occurs within a system, and as such, so do behaviors in performance-related domains (e.g., athletics, academics). Doping is a performance enhancement behavior that can be problematic because of the negative physical and psychological effects associated with the use of some substances and the common argument that doping is unfair. However, doping continues and may be increasing. Because a firm theoretical or empirical understanding of doping does not exist, this article proposes a conceptual, comprehensive, and innovative systemic model of doping behavior. The model is built from relevant empiricism supporting the idea that contemporary doping behavior is a function of systemic transactions between historical doping practices, the present environment, current antidoping interventions, one's genetic makeup, developmental milestones, social factors, and epigenetics.  相似文献

There are abundant anecdotes and warnings of inappropriate behaviors on social networking sites, particularly about Facebook. The purpose of the present study was to examine whether individuals obsessively monitor or harass their ex-partners on Facebook (related to general "Facebook stalking") and, if so, whether those individuals would also engage in cyber obsessional pursuit (COP) and obsessive relational pursuit (ORI), which are categories of cyberstalking and stalking. A total of 411 valid participants answered questions about the ways they communicated with their ex-romantic partners using Facebook, resulting in three factors: Covert Provocation, Public Harassment, and Venting. Each category of Facebook harassment was related to perpetration of COP and ORI. Additionally, participants who engaged in COP were almost six times more likely to also perpetrate ORI. If participants admitted to engaging in some types of stalking behaviors, they did so online, offline, and on Facebook. Implications for social networking site usage and stalking laws are discussed. There is a kernel of truth to the popular term "Facebook stalking."  相似文献

This essay charts the origins, influences, and evolution of the relational tradition in contemporary psychoanalysis. Considering the theoretical and philosophical influences from nineteenth-century Americans like William James and C. S Pierce, and noting the seminal modern work of Steven Mitchell and Jay Greenberg in opening a critique of one-person focused drive theory, the essay follows developments over a quarter century. Hallmarks of the relational approach-social construction, two-person psychologies, multiple self-states, social regulation and construction of identities like gender and sexual orientation, and an evolving theory of clinical practice-are reviewed. New developments in clinical theory, in the study of identity categories, in the work on embodiment and enactment, and in developmental models are also reviewed.  相似文献

We treated the liquid refusal of a 15-month-old girl using 2 antecedent manipulations: flipped spoon and chin prompt. Use of the chin prompt in the absence of the flipped spoon failed to produce increases in mouth clean (a product measure of swallowing). By contrast, modest increases in mouth clean resulted from the implementation of the flipped spoon alone. The greatest increases in mouth clean resulted from the combination of the 2 manipulations.  相似文献

We observed 11 undergraduates in an experiment designed to simulate infant caregiving. In negative reinforcement conditions experienced by all participants, a targeted caregiving response (e.g., rocking a baby doll) produced escape from, and avoidance of, a recorded infant cry. Nine participants' caregiving was shown to be controlled by this negative reinforcement contingency. Nine participants experienced an extinction condition that consisted of an inescapable cry, and the previously reinforced caregiving responses of 2 of these participants were resistant to extinction. For both of these participants, the previously reinforced response was eliminated when an alternative form of caregiving was reinforced. These results highlight the role of negative reinforcement in infant caregiving and suggest the need for additional research on the effects of crying on caregivers as well as the development of effective strategies for minimizing infant crying.  相似文献
