Outsourcing of jobs to contract workers who work alongside a client's employees has changed the human resource landscape of many organizations. In this study we examine how a contract worker's perceived employment status similarity to the client's own standard employees influences his/her affective commitment to both the client and the employer and ultimately intent to quit the employer. Using a sample of 623 contract workers, we found strong support for our hypotheses. In particular, findings indicate an important role for perceived employment status at the client organization in driving contract worker's attitudes and that contract workers consider both the client and the employer when making decisions to leave the employer. Implications for managing contractor relationships are discussed. 相似文献

Six- and nine-yr.-old children (n=28 of each) were divided into equal experimental and control groups. The experimental groups were shown a film with a magical theme, and the control groups were shown a film with a nonmagical theme. All groups then were presented with a choice task requiring them to discriminate between ordinary and fantastic visual displays on a computer screen. Statistical analyses indicated that mean scores for correctly identifying the ordinary and fantastic displays were significantly different between experimental and control groups. The children in the experimental groups who watched the magical film had significantly higher scores on correct identifications than children in the control groups who watched the nonmagical film for both age groups. The results suggest that watching films with a magical theme might enhance children's sensitivity toward the fantasy/reality distinction. 相似文献

Mediation analysis uses measures of hypothesized mediating variables to test theory for how a treatment achieves effects on outcomes and to improve subsequent treatments by identifying the most efficient treatment components. Most current mediation analysis methods rely on untested distributional and functional form assumptions for valid conclusions, especially regarding the relation between the mediator and outcome variables. Propensity score methods offer an alternative whereby the propensity score is used to compare individuals in the treatment and control groups who would have had the same value of the mediator had they been assigned to the same treatment condition. This article describes the use of propensity score weighting for mediation with a focus on explicating the underlying assumptions. Propensity scores have the potential to offer an alternative estimation procedure for mediation analysis with alternative assumptions from those of standard mediation analysis. The methods are illustrated investigating the mediational effects of an intervention to improve sense of mastery to reduce depression using data from the Job Search Intervention Study (JOBS II). We find significant treatment effects for those individuals who would have improved sense of mastery when in the treatment condition but no effects for those who would not have improved sense of mastery under treatment. 相似文献

Individuals often conform to the intergroup attitudes and behaviors modeled by their peers in a given situation. To what extent does peer influence on intergroup prejudice 1) diffuse across a social network of peers and 2) affect attitudes and behavior across time? Student leaders (“Peer Trainers”) were trained to confront expressions of intergroup prejudice in five randomly assigned high schools across a period of five months; students recruited to be Peer Trainers in five control schools waited to be trained. Independent surveys of Peer Trainers' social networks reveal that treatment Peer Trainers were significantly more likely than control Trainers to be nominated by peers as students who confront prejudice. Treatment Peer Trainers' tolerant behavior spread to close friends and to acquaintances in their social network; their attitudes spread inconsistently, and only to close friends. Studying peer influence within social networks can improve understanding of social influence, prejudice reduction, and social change. 相似文献

When making decisions, people typically gather information from both social and nonsocial sources, such as advice from others and direct experience. This research adapted a cognitive learning paradigm to examine the process by which people learn what sources of information are credible. When participants relied on advice alone to make decisions, their learning of source reliability proceeded in a manner analogous to traditional cue learning processes and replicated the established learning phenomena. However, when advice and nonsocial cues were encountered together as an established phenomenon, blocking (ignoring redundant information) did not occur. Our results suggest that extant cognitive learning models can accommodate either advice or nonsocial cues in isolation. However, the combination of advice and nonsocial cues (a context more typically encountered in daily life) leads to different patterns of learning, in which mutually supportive information from different types of sources is not regarded as redundant and may be particularly compelling. For these situations, cognitive learning models still constitute a promising explanatory tool but one that must be expanded. As such, these findings have important implications for social psychological theory and for cognitive models of learning. 相似文献

The present study examined the flexibility with which people can adopt different category schemes in the spatial domain. In
a location memory task, participants viewed and estimated the locations of four kinds of objects that were spatially grouped
by object identity. This identity-based arrangement was either congruent or incongruent with the perceptually based, geometric
categories that have been reported in previous research. Four experiments examined the conditions under which these different
category schemes are used to inform estimates of locations. The results showed that use of identity information depended on
the number of objects to be remembered during a trial: When one or two objects were remembered at a time, only geometric categories
affected estimates, but when four objects were to be remembered, both geometric categories and identity groupings affected
estimates. As memory load increases, participants rely on additional sources to inform their estimates of location. 相似文献

This study examined the association between childhood ADHD and juvenile delinquency by examining data from the Pittsburgh
ADHD Longitudinal Study (PALS), a follow-up study of individuals diagnosed with ADHD in childhood (ages 5–12) and recontacted
in adolescence and young adulthood for yearly follow-up (age at first follow-up interview M = 17.26, SD = 3.17). Participants were 288 males with childhood ADHD and 209 demographically similar males without ADHD who were recruited
into the follow-up study. Delinquency information gathered yearly during the second through eighth follow-up provided a comprehensive
history of juvenile delinquency for all participants. Four childhood diagnostic groups [ADHD-only (N = 47), ADHD + ODD (N = 135), ADHD + CD (N = 106), and comparison (N = 209)] were used to examine group differences on delinquency outcomes. Analyses were conducted across three dimensions of
delinquency (i.e., severity, age of initiation, and variety). Individuals with childhood ADHD + CD displayed significantly
worse delinquency outcomes than the other three groups, across almost all indices of offending. When compared to comparison
participants, boys with ADHD-only and ADHD + ODD in childhood displayed earlier ages of delinquency initiation, a greater
variety of offending, and higher prevalence of severe delinquency. These findings suggest that although childhood ADHD + CD
creates the greatest risk for delinquency, boys with ADHD-only and ADHD + ODD also appear at a higher risk for later offending.
The patterns of offending that emerged from the PALS are discussed in the context of the relationship between ADHD, comorbidity,
and delinquency. 相似文献

People tend to respond with more positive than negative affect to mildly emotional stimuli (i.e., positivity offset) and respond more strongly to very negative than to matched positive stimuli (i.e., negativity bias). In the current study, the authors examine individual differences in the positivity offset and negativity bias and demonstrate that both are stable over time and generalize across different kinds of stimuli (e.g., pictures, sounds, words, games of chance). Furthermore, the positivity offset and negativity bias are not redundant with traditional personality measures and exhibit differential predictive validity, such that both types of measures predict behavior in meaningful ways. Implications for a comprehensive understanding of affect and emotion and their relationship to physical and mental health are discussed. 相似文献
