The authors propose new procedures for evaluating direct, indirect, and total effects in multilevel models when all relevant variables are measured at Level 1 and all effects are random. Formulas are provided for the mean and variance of the indirect and total effects and for the sampling variances of the average indirect and total effects. Simulations show that the estimates are unbiased under most conditions. Confidence intervals based on a normal approximation or a simulated sampling distribution perform well when the random effects are normally distributed but less so when they are nonnormally distributed. These methods are further developed to address hypotheses of moderated mediation in the multilevel context. An example demonstrates the feasibility and usefulness of the proposed methods. 相似文献

In this study the authors explored the relation of physical appearance, perception of group belonging, and perception of group exclusion to racial/ethnic identity in multiracial Japanese European Americans. Results indicate that physical appearance and social variables of sense of belonging and exclusion related to one monoracial racial/ethnic group significantly predicted self-identity with the corresponding monoracial group. There was also a significant relationship between Japanese American identity and multiracial appearance and social variables. Feelings of exclusion were shown to be the primary influence on all three racial/ethnic identities. 相似文献

It is easier to identify a degraded familiar face when it is shown moving (smiling, talking; nonrigid motion), than when it is displayed as a static image (Knight & Johnston, 1997; Lander, Christie, & Bruce, 1999). Here we explore the theoretical underpinnings of the moving face recognition advantage. In Experiment 1 we show that the identification of personally familiar faces when shown naturally smiling is significantly better than when the person is shown artificially smiling (morphed motion), as a single static neutral image or as a single static smiling image. In Experiment 2 we demonstrate that speeding up the motion significantly impairs the recognition of identity from natural smiles, but has little effect on morphed smiles. We conclude that the recognition advantage for face motion does not reflect a general benefit for motion, but suggests that, for familiar faces, information about their characteristic motion is stored in memory. 相似文献

It has been suggested that over-scheduling of upper-class youth might underlie the high distress and substance use documented among them. This assumption was tested by considering suburban 8th graders' involvement in different activities along with their perceptions of parental attitudes toward achievement. Results indicated negligible evidence for deleterious effects of high extracurricular involvement per se. Far more strongly implicated was perceived parent criticism for both girls and boys as well as the absence of after-school supervision. Low parent expectations connoted significant vulnerability especially for boys. The findings indicate that at least among early adolescents, converging scientific and media reports may have scapegoated extracurricular involvements, to some degree, as an index of ubiquitous achievement pressures in affluent communities. 相似文献

Pigeons were trained on many-to-one matching in which pairs of samples, each consisting of a visual stimulus and a distinctive pattern of center-key responding, occasioned the same reinforced comparison choice. Acquired equivalence between the visual and response samples then was evaluated by reinforcing new comparison choices to one set of samples, and examining generalization of these choices to the other samples. Three separate experiments found no evidence of such generalization, as indexed by performance on class-consistent versus class-inconsistent tests. Other tests showed that the pigeons' center-key response patterns during training had indeed served as a conditional cue for choice. These results do not support the hypothesis that different defined responses can become members of acquired equivalence classes. 相似文献

Although Dull and Skokan (1995) proposed a cognitive model of the effect of religion on health, they neglected to clearly identify the multi-dimensional nature of religion as a cognitive schema. The present paper identifies various aspects of spiritual disposition (defined as personality and beliefs) that can play a role in an individual’s adaptation to illness. Specifically, this paper reviews the factors of religious doctrine and affiliation, spiritual beliefs, religious orientation, God locus of control, faith and hope as aspects of a spiritual disposition and explores how they can function as resources and/or negative factors in the process of adjustment to illness. Implications for clinical health care (e.g., pastoral counsellors) are drawn from this review. 相似文献

This article summarizes discussions that took place following Paul Toros presidential address for the Society for Community Research and Action (SCRA). Toro argued that community psychology and SCRA are big tents. He suggested growth through increasing the involvement of ethnic minorities, community practitioners, international colleagues, students and early career professionals and individuals from allied disciplines. Themes in the discussions included: the founding values of community psychology, diversity, and social action. Those present felt that the field was facing a mid-life crisis and needed to re-establish its identity. Newer professionals looked to their seasoned colleagues to help define and establish that identity, and involve them in the process. Respondents were supportive of increased involvement of individuals from oppressed groups and practitioners in SCRA. Less attention was paid to increasing the role of international colleagues, professionals from allied disciplines, and members of the community. 相似文献

Two studies compared leader-member exchange (LMX) theory and the social identity theory of leadership. Study 1 surveyed 439 employees of organizations in Wales, measuring work group salience, leader-member relations, and perceived leadership effectiveness. Study 2 surveyed 128 members of organizations in India, measuring identification not salience and also individualism/collectivism. Both studies provided good support for social identity predictions. Depersonalized leader-member relations were associated with greater leadership effectiveness among high-than low-salient groups (Study 1) and among high than low identifiers (Study 2). Personalized leadership effectiveness was less affected by salience (Study 1) and unaffected by identification (Study 2). Low-salience groups preferred personalized leadership more than did high-salience groups (Study 1). Low identifiers showed no preference but high identifiers preferred depersonalized leadership (Study 2). In Study 2, collectivists did not prefer depersonalized as opposed to personalized leadership, whereas individualists did, probably because collectivists focus more on the relational self. 相似文献
