Scholars have consistently identified contextual performance or organizational citizenship behavior as a core component of job performance. The current literature on this issue has been dominated by a single-level approach, typically conducted at the individual level of analysis. This study adopts a multilevel approach to simultaneously examine main effects of and cross-level interactions among individual- and group-level predictors of interpersonal helping behavior. Results from a large-scale longitudinal data set show that at the individual level, helping behavior was predicted by perceived organizational support (POS), fairness, and affective commitment. At the group level, helping behavior was predicted by trust among group members. Trust among members also significantly moderated the individual-level relationships between POS and helping behavior and between fairness and helping. These crosslevel moderations indicated that the group- and individual-level predictors were complementary (instead of mutually reinforcing) in predicting interpersonal helping behavior. This finding indicates that various antecedents of interpersonal helping are characterized by distinct dynamics at the individual and group levels of analysis. 相似文献

Social support and coping adaptability were explored as factors leading to successful outcomes in initial military training. Hierarchical regression and bootstrapping of indirect effects were used to explore these relationships in a sample of 2,293 New Zealand Defence Force trainees. Support from instructors was related to lower difficulty coping and higher performance and military belonging. Support from external sources was related to higher coping adaptability, performance, military belonging, and, paradoxically, increased difficulty coping. Coping adaptability mediated the beneficial effects of external support. Resources provided by different sources of support, applications, limitations, and directions for future research are discussed. 相似文献

Anger and aggression are common combat-related behavioral health problems. The impact of combat on anger and aggression appears to be largely attributable to symptoms of posttraumatic stress disorder (PTSD). Factors that moderate the purported pathway from combat to anger and aggression are poorly understood. We examined the conditional direct and indirect associations of combat exposure with self-reported anger and aggression using survey data collected from 592 U.S. Soldiers during a combat deployment in Afghanistan. Unit morale was examined as a moderator between combat exposure and PSTD symptoms, as well as the indirect association of combat exposure with anger and aggression via PTSD symptoms, controlling for depression symptoms. Results indicated that unit morale was negatively correlated with PTSD symptoms and self-reported anger and aggressive behaviors. Perceptions of unit morale moderated the direct association of combat exposure with PTSD symptoms. Unit morale also moderated the indirect association of combat exposure with anger and aggression through PTSD symptoms. Unit morale moderated the association of combat exposure with anger and aggression during combat operations by putatively mitigating the deleterious effect of combat on stress-related symptoms. The impact of policy and leadership on soldier and unit morale should be carefully considered given its protective role during combat operations. 相似文献

Physiological synchrony within a dyad, or the degree of temporal correspondence between two individuals' physiological systems, has become a focal area of psychological research. Multiple methods have been used for measuring and modeling physiological synchrony. Each method extracts and analyzes different types of physiological synchrony, where ‘type’ refers to a specific manner through which two different physiological signals may correlate. Yet, to our knowledge, there is no documentation of the different methods, how each method corresponds to a specific type of synchrony, and the statistical assumptions embedded within each method. Hence, this article outlines several approaches for measuring and modeling physiological synchrony, connects each type of synchrony to a specific method, and identifies the assumptions that need to be satisfied for each method to appropriately extract each type of synchrony. Furthermore, this article demonstrates how to test for between-dyad differences of synchrony via inclusion of dyad-level (i.e., time-invariant) covariates. Finally, we complement each method with an empirical demonstration, as well as online supplemental material that contains Mplus code. 相似文献

Parents and children and adolescents commonly disagree in their perceptions of a variety of behaviors, including the family relationship and environment, and child and adolescent psychopathology. To this end, numerous studies have examined to what extent increased discrepant perceptions—particularly with regard to perceptions of the family relationship and environment—predict increased child and adolescent psychopathology. Parents’ and children and adolescents’ abilities to decode and identify others’ emotions (i.e., emotion recognition) may play a role in the link between discrepant perceptions and child and adolescent psychopathology. We examined parents’ and adolescents’ emotion recognition abilities in relation to discrepancies between parent and adolescent perceptions of daily life topics. In a sample of 50 parents and adolescents ages 14-to-17 years (M?=?15.4 years, 20 males, 54 % African-American), parents and adolescents were each administered a widely used performance-based measure of emotion recognition. Parents and adolescents were also administered a structured interview designed to directly assess each of their perceptions of the extent to which discrepancies existed in their beliefs about daily life topics (e.g., whether adolescents should complete their homework and carry out household chores). Interestingly, lower parent and adolescent emotion recognition performance significantly related to greater parent and adolescent perceived discrepant beliefs about daily life topics. We observed this relation whilst accounting for adolescent age and gender and levels of parent-adolescent conflict. These findings have important implications for understanding and using informant discrepancies in both basic developmental psychopathology research and applied research in clinic settings (e.g., discrepant views on therapeutic goals). 相似文献

Functional magnetic resonance imaging (fMRI) was used to assess neural activation as participants learned to segment continuous streams of speech containing syllable sequences varying in their transitional probabilities. Speech streams were presented in four runs, each followed by a behavioral test to measure the extent of learning over time. Behavioral performance indicated that participants could discriminate statistically coherent sequences (words) from less coherent sequences (partwords). Individual rates of learning, defined as the difference in ratings for words and partwords, were used as predictors of neural activation to ask which brain areas showed activity associated with these measures. Results showed significant activity in the pars opercularis and pars triangularis regions of the left inferior frontal gyrus (LIFG). The relationship between these findings and prior work on the neural basis of statistical learning is discussed, and parallels to the frontal/subcortical network involved in other forms of implicit sequence learning are considered. 相似文献

Objective: The present study investigates the effects of graphic cigarette warnings compared to text-only cigarette warnings on smokers’ explicit (i.e. ratings of the packages, cognitions about smoking, perceived health risk, quit intentions) and implicit attitudes. In addition, participants’ visual attention towards the graphic warnings was recorded using eye-tracking methodology.Design and methods: Sixty-three smokers participated in the present study and either viewed graphic cigarette warnings with aversive and non-aversive images or text-only warnings. Data were analysed using analysis of variance and correlation analysis.Results: Especially, graphic cigarette warnings with aversive content drew attention and elicited high threat. However, whereas attention directed to the textual information of the graphic warnings predicted smokers’ risk perceptions, attention directed to the images of the graphic warnings did not. Moreover, smokers’ in the graphic warning condition reported more positive cognitions about smoking, thus revealing cognitive dissonance.Conclusion: Smokers employ defensive psychological mechanisms when confronted with threatening warnings. Although aversive images attract attention, they do not promote health knowledge. Implications for graphic health warnings and the importance of taking their content (i.e. aversive vs. non-aversive images) into account are discussed. 相似文献

AbstractObjective: Because the working memory (WM) has a limited capacity, the cognitive reactions towards persuasive information in the WM might be disturbed by taxing it by other means, in this study, by inducing voluntary eye movements (EMi). This is expected to influence persuasion.Methods: Participants (N?=?127) listened to an auditory persuasive message on fruit and vegetable consumption, that was either framed positively or negatively. Half of them was asked to keep following a regularly moving dot on their screen with their eyes. At pretest, cognitive self-affirmation inclination (CSAI) was assessed as individual difference to test possible moderation effects.Results: The EMi significantly lowered the quality of the mental images that participants reported to have of the persuasive outcomes. With regard to self-reported fruit and vegetable consumption after two weeks, EMi significantly lowered consumption when CSAI was high but it significantly increased consumption when CSAI was low.Conclusions: The results verify our earlier findings that induced EM can influence persuasion. Although it remains unclear whether the effects of EMi were caused by disturbing mental images of persuasive outcomes or self-regulative reactions to these images, or both, the WM account may provide new theoretical as well as practical angles on persuasion. 相似文献

Although word recognition deficits (WRD) are a known cause of reading comprehension deficits (RCD), other contributions to RCD, including executive function (EF), have not been fully explored. We examined the contribution of EF (working memory and planning), along with attention, decoding, fluency, and vocabulary to reading comprehension in 60 children (including 16 WRD and 10 RCD), ages 9–15 years. After controlling for commonly accepted contributors to reading comprehension (i.e., attention, decoding skills, fluency, and vocabulary), EF continued to make a significant contribution to reading comprehension but not to word recognition skills. These findings highlight the need for consideration of the role of EF in RCD. 相似文献
