Numerous studies have shown that perceived organizational support has positive consequences on both employees and organizations. However, no study has examined the causal relationship between perceived organizational support and proactive behaviour directed towards the organization and few studies have identified potential mechanisms underlying this relationship. We first investigated the direction of causality between perceived organizational support and proactive behaviour, and hypothesized that perceived organizational support leads to proactive behaviour directed towards the organization. Second, based on social exchange and motivational perspectives, we examined two potential mechanisms underlying this relationship, i.e., felt obligation and work engagement. Employees from a Belgian Federal Public Service were invited to take part in a three-wave longitudinal survey. Using a cross-lagged panel design, our results (N = 1963) revealed that Time 2 perceived organizational support was positively related to Time 3 proactive behaviour towards the organization, whereas the reverse was not true. Additionally, our results (N = 1293) showed that Time 2 felt obligation and Time 2 work engagement mediated the positive relationship between Time 1 perceived organizational support and Time 3 proactive behaviour directed towards the organization.  相似文献

The main goal of the current study was to investigate sex differences in the relationship between the level of trauma symptoms appearing in posttraumatic stress disorder (PTSD) and intensity of pain in a sample of 300 Polish patients suffering from chronic pain, specifically rheumatoid arthritis and lower back pain. We also focused on participants’ body image with body esteem as a mediator. To assess the intensity of pain among participants, we used the Numerical Rating Scale. The level of trauma symptoms was assessed with the PTSD Factorial Version Inventory. To measure body image among participants, we used the Body Esteem Scale. The results of our study suggest that trauma symptoms and body image dimensions were significant predictors of pain intensity among men suffering from chronic pain. Moreover, trauma symptoms and age were significant predictors of pain intensity among women suffering from chronic pain. Finally, we demonstrated that sex differentiates the reaction to chronic pain.  相似文献

Some people might believe that individuals who are more satisfied with their body are also happier. However, people tend to overrate the influence of some factors (e.g. money or health) on their happiness; a phenomenon termed the focusing illusion. Our aim was to examine the focusing illusion in relation to body satisfaction. We experimentally manipulated body satisfaction and life satisfaction focus by varying the order of relevant measurement scales. Volunteers (N = 97) completed two questionnaires placed in separate envelopes to control the order of scales administration. Participants either completed the Body Satisfaction Scale followed by the Satisfaction with Life Scale or vice versa. In line with the focusing illusion the association between body satisfaction and life satisfaction was significantly stronger when participants were asked about their body satisfaction first. Body satisfaction as a focusing illusion may need to be considered by scientist as well as lay people who try to look better and be happier.  相似文献

Previous research suggests that early mentoring relationship (MR) closures may have harmful consequences for the health and well‐being of youth participating in community‐based mentoring programs. However, knowledge of the factors that lead some MRs to close early has been slow to emerge. This study examined patterns and correlates of early versus on‐time MR closures among 569 youth participating in Big Brothers Big Sisters community mentoring programs. Thirty‐four percent of youth experienced an early MR closure prior to the end of the program's 12 month period of commitment. The probability of closure was highest at 12 months into the MR. Early closures were positively associated with youth gender (girls), behavioral difficulties, and match determination difficulties. Early and on‐time closures were associated with youth extrinsic motives for joining the program. Early MR closures were negatively associated with youth perceptions of parent emotional support, parent social support, high quality MR, weekly contact in MR, and parent support of the MR. Implications for programming are discussed.  相似文献

Previous research indicates that political conservatism is associated with epistemic needs for structure and certainty (Jost et al., 2003) and that nouns elicit clearer and more definite perceptions of reality than other parts of speech (Carnaghi et al., 2008). We therefore hypothesized that conservatives would exhibit preferences for nouns (vs. verbs and adjectives), insofar as nouns are better suited to satisfy epistemic needs. In Study 1, we observed that social conservatism was associated with noun preferences in Polish and that personal need for structure accounted for the association between ideology and grammatical preferences. In Study 2, conducted in Arabic, social conservatism was associated with a preference for the use of nominal sentences (composed of nouns only) over verbal sentences (which included verbs and adjectives). In Study 3, we found that more conservative U.S. presidents used greater proportions of nouns in major speeches, and this effect was related to integrative complexity. We discuss the possibility that conservative ideology is linked to grammatical preferences that foster feelings of stability and predictability.  相似文献

Several personality models are known for being replicable across cultures, such as the Five‐Factor Model (FFM) or Eysenck's Psychoticism–Extraversion–Neuroticism (PEN) model, and are for this reason considered universal. The aim of the current study was to evaluate the cross‐cultural replicability of the recently revised Alternative FFM (AFFM). A total of 15 048 participants from 23 cultures completed the Zuckerman–Kuhlman–Aluja Personality Questionnaire (ZKA‐PQ) aimed at assessing personality according to this revised AFFM. Internal consistencies, gender differences and correlations with age were similar across cultures for all five factors and facet scales. The AFFM structure was very similar across samples and can be considered as highly replicable with total congruence coefficients ranging from .94 to .99. Measurement invariance across cultures was assessed using multi‐group confirmatory factor analyses, and each higher‐order personality factor did reach configural and metric invariance. Scalar invariance was never reached, which implies that culture‐specific norms should be considered. The underlying structure of the ZKA‐PQ replicates well across cultures, suggesting that this questionnaire can be used in a large diversity of cultures and that the AFFM might be as universal as the FFM or the PEN model. This suggests that more research is needed to identify and define an integrative framework underlying these personality models.

The aim of this study was to assess the memory of pain induced by running a marathon and the factors that influence it. Sixty-two marathon runners participated in the study, which comprised two phases. Immediately after a participant had reached the finishing line of the marathon, they were asked to rate the intensity and the unpleasantness of their pain and the emotions they felt at that time. Either three or six months later they were asked again to rate the intensity and the unpleasantness of the same pain experience. Regardless of the length of recall delay, participants underestimated both recalled pain intensity and unpleasantness. The pain and negative affect reported at the time of the pain experience accounted for 24% of the total variance in predicting recalled pain intensity and 22% of the total variance in predicting recalled pain unpleasantness. Positive affect at the time of pain experience was not a significant predictor of both the recalled pain intensity and pain unpleasantness. It is concluded that pain induced by physical exercise is not remembered accurately and the pain and negative affect experienced influence recall. Further research is needed on the influence of positive affect on the memory of pain.  相似文献

The main goal of the paper is to sketch an ontological model of visual content at the low- and medium-level of visual processing, relying on psychological conceptions of vision. It is argued that influential cognitive models contain assumptions concerning “objects of content,” that is, objects whose presence is a necessary condition of the adequacy of visual representations. Subsequently, the structure of considered objects of content is presented, and its development through the perceptual process is described. In addition, during the course of the article I present some connections between analytic metaphysics and the ontology of visual content.  相似文献

This article provides an overview of the literature on the relation between intelligence and nutrition. The first two sections introduce some data on the prevalence of malnutrition across the planet, and show how studies of animal cognition can help to understand the impact of malnutrition on human cognitive functioning. The third section introduces the effects of general “denutrition” and of iron, zinc, iodine, and vitamin deficiencies. The last two sections emphasize the impact of breastfeeding on intellectual and academic performance, and the importance of breakfast with regard to the ability to learn.  相似文献

This study examines the problem of belief revision, defined as deciding which of several initially accepted sentences to disbelieve, when new information presents a logical inconsistency with the initial set. In the first three experiments, the initial sentence set included a conditional sentence, a non-conditional (ground) sentence, and an inferred conclusion drawn from the first two. The new information contradicted the inferred conclusion. Results indicated that conditional sentences were more readily abandoned than ground sentences, even when either choice would lead to a consistent belief state, and that this preference was more pronounced when problems used natural language cover stories rather than symbols. The pattern of belief revision choices differed depending on whether the contradicted conclusion from the initial belief set had been a modus ponens or modus tollens inference. Two additional experiments examined alternative model-theoretic definitions of minimal change to a belief state, using problems that contained multiple models of the initial belief state and of the new information that provided the contradiction. The results indicated that people did not follow any of four formal definitions of minimal change on these problems. The new information and the contradiction it offered was not, for example, used to select a particular model of the initial belief state as a way of reconciling the contradiction. The preferred revision was to retain only those initial sentences that had the same, unambiguous truth value within and across both the initial and new information sets. The study and results are presented in the context of certain logic-based formalizations of belief revision, syntactic and model-theoretic representations of belief states, and performance models of human deduction. Principles by which some types of sentences might be more “entrenched” than others in the face of contradiction are also discussed from the perspective of induction and theory revision.  相似文献
