Previous meta-analyses have estimated that the intention–behaviour association in physical activity (PA) is large in magnitude. However, these prior meta-analyses have also revealed a large degree of heterogeneity, suggesting the presence of moderating variables. This study examines the impact of one such moderator, testing the hypothesis that the magnitude of the association between intention and behaviour decreases as the temporal separation between the two increases. A systematic literature search was used to identify published and unpublished studies that met the inclusion criteria. A random-effects meta-regression was conducted to test the study hypothesis. A total of 78 journal articles and 11 unpublished dissertations were identified, yielding 109 effect sizes. The mean number of weeks between the measurement of intention and behaviour was 5.4 (SD = 6.6, range = .43, 26). The average correlation between intention and behaviour was r = 0.51. In line with theoretical predictions, temporal separation was a significant moderator of the intention–behaviour correlation (B = ?.014, p < .001) and explained 24% of the between-study variance. This result remained unchanged when entered simultaneously with several control variables. The results of this analysis have important implications both for researchers and for intervention designers aiming to increase rates of PA. 相似文献

The goal of this project has been to explore the characteristics of the self as a complex adaptive system. It began with the effort to provide a foundation for a developmental theory based on principles from self psychology that also permitted the incorporation of some of the recent findings from neuroscience. Part I (Palombo, 2013a) outlined some features of nonlinear dynamic systems theory and complexity science that provided the basis for a critique of traditional psychodynamic developmental theories. This critique was followed in Part II (Palombo, 2013b) with the proposal of a levels-of-analysis perspective as a methodology to organize the data on development, the three levels of analysis being the neuropsychological, the introspective, and the interpersonal. This article, Part III, outlines the trends that contributed to the revised view of development and proposes a set of processes that are consistent with a nonlinear dynamic perspective that govern human beings' mental activities during development. These processes are the progression from lower to higher levels of complexity, the movement from lesser to greater differentiation, and advancement from lesser to greater individuation. 相似文献

This prospective study assessed the temporal relationships between the symptom clusters of PTSD in two nonprobability samples of treatment-seeking victims of sexual abuse: rape victims and adult survivors of childhood sexual abuse. Both groups were assessed at three time periods using self-report measures of PTSD symptomology. Findings from two cross-lagged panel analyses indicated weak temporal relationships between the symptom clusters of PTSD; however, avoidance and emotional numbing symptoms were found to exert the strongest cross-lagged effects. Avoidance and emotional numbing symptoms were also found to be the strongest predictor of subsequently meeting caseness for PTSD in both samples. Results suggest that there are minimal cross-lagged effects between the PTSD symptom clusters after three months from traumatic exposure. 相似文献

What role does experience play in the development of face recognition? A growing body of evidence indicates that newborn brains need slowly changing visual experiences to develop accurate visual recognition abilities. All of the work supporting this “slowness constraint” on visual development comes from studies testing basic-level object recognition. Here, we present the results of controlled-rearing experiments that provide evidence for a slowness constraint on the development of face recognition, a prototypical subordinate-level object recognition task. We found that (1) newborn chicks can rapidly develop view-invariant face recognition and (2) the development of this ability relies on experience with slowly moving faces. When chicks were reared with quickly moving faces, they built distorted face representations that largely lacked invariance to viewpoint changes, effectively “breaking” their face recognition abilities. These results provide causal evidence that slowly changing visual experiences play a critical role in the development of face recognition, akin to basic-level object recognition. Thus, face recognition is not a hardwired property of vision but is learned rapidly as the visual system adapts to the temporal structure of the animal's visual environment. 相似文献

Drawing on social hierarchy theory, we develop a contingency model of leader–member exchange (LMX) differentiation in which LMX differentiation is positively and negatively related to group cooperation and group social undermining, respectively, when it is based on the group members’ performance, but the relations are reversed (i.e., negative and positive, respectively) when it stems from a leader's personal liking of the members. In addition, we propose that the moderating effects of the performance and personal liking bases of LMX differentiation are magnified by the levels of reward interdependence. Specifically, under a high (vs. low) level of reward interdependence, LMX differentiation based on performance more strongly relates to high group cooperation and low group social undermining, whereas LMX differentiation with a personal liking basis is more likely to decrease group cooperation and increase group social undermining. Group cooperation and social undermining are then hypothesized to convey the three‐way interactive effects of LMX differentiation, its two bases, and reward interdependence on subsequent group performance. Analyses of data from 328 sales groups of a large retailer support the core part of our contingency model of LMX differentiation. 相似文献

The episodic effect suggests that episodic prospection (imagining future events) can effectively reduce time discounting, the propensity to discount the value of delayed rewards relative to immediate ones. However, less clear is how episodic prospection modulates time preference. As engagement in episodic prospection usually evokes prospective emotions, it was proposed that episodic prospection might work by inducing prospective emotions. Although one previous study has attempted to provide evidence to the emotional account of the episodic effect, shortcomings in its experimental design make its conclusion questionable. In this study, we replicated previous experimental design with improvements to further test the effects of prospective emotion on time preference. By manipulating the emotional valency associated with episodic prospection in a delay discounting task, we found that positive episodic prospection attenuated time discounting; negative episodic prospection exacerbated time discounting; and episodic prospection did not shift time preference when prospective emotion is removed. These results were essentially identical to the result of the previous study. Together, these studies suggested that the effects of episodic prospection depended on prospective emotion. Thus, one cannot ignore prospective emotion if counting on episodic prospection to combat humans’ impulsive behaviours. 相似文献

We investigated the role of anticipation of feedback in performance and estimation about own performance. We submitted 155 participants to a test of verbal aptitude, and we requested them to give estimations of their own performance and the performance of other participants. There were two treatments: immediate feedback and delayed feedback. Participants in the immediate‐feedback group were informed that they would receive feedback on their performance immediately after finishing the test, whereas participants in the delayed‐feedback group were informed that they would receive feedback a week after taking the test. The immediate‐feedback group performed better than the delayed‐feedback group. Furthermore, the former underestimated their own performance. On the other hand, participants on the delayed‐feedback group made unbiased estimations. We present a mathematical model based on construal‐level theory, decision affect theory, temporal discounting, and Moore and Healy's model of overestimation. The model suggests that the source of differences in performance and in estimations of own performance is a construal of the feedback situation that modifies the expected utility of the task. 相似文献

The word any may appear in some sentences, but not in others. For example, any is permitted in sentences that contain the word nobody, as in Nobody ate any fruit. However, in a minimally different context any seems strikingly anomalous: *Everybody ate any fruit. The aim of the present study was to investigate how the brain responds to the word any in such minimally different contexts - where it is permitted (licensed) and where it is not permitted (unlicensed). Brain responses were measured from adult readers using magnetoencephalography (MEG). The results showed significantly larger responses to permissible contexts in the left posterior temporal areas between 400-500 ms and 590-660 ms. These results clarify the anatomy and timing of brain processes that contribute to our judgment that a word such as any is or is not permitted in a given context. 相似文献

This article builds on the notion of legal tolerance and analyzes the scope of its definition. It situates the notion in the complex set of relations occurring between the major systems of society. Generally, legal tolerance, as a concept, is understood in light of the possibilities of the legal system of influencing other major systems’ responses. On the other hand, tolerance is also the response of the legal system in respect to other major systems’ communications. Although there is a common understanding of tolerance as “under punishing bias” in criminology or as political tolerance in political science, 1 the focus of this article is different. The central points here are, first, the analysis of legal tolerance as part of systemic communications and, second, the historicity of the transformations of the nation-state in its ability to cope with the growth of separate, distinct and partial systems of society. Tolerance seems relational and raises questions such as: “How much can the legal system tolerate?” And also, “Which societal topics belong to the social system's domain-matter?” These questions are relevant given that the concept of legal tolerance depends on the possibilities of a given system to steer, to direct or to influence other major systems’ behavior, or to resist, respond or to address other systems, which are in its environment. The concept of legal tolerance requires an analysis of a cluster of related definitions to assess the implications of the concept. These definitions are the following: (1) The concepts that result from the historical process of structuration and that explain the emergence of social systems. (2) The definition of reflexivity and its relation with the “second order cybernetics dilemma.” This is the place where heuristic and epistemological problems are found. Such problems result from both the problem of representation and from the ontological status of the real. This analysis will show why reflexivity is a key concept to explaining the transformations suffered by such systems. Then, legal tolerance is a newer development in respect to the idea of planning. As an alternative to hard planning, legal tolerance creates a fostering environment. Instead of a single system directing other systems, legal tolerance is relational and created collectively by the organizational national state using its (limited) power of legal creation. Legal tolerance also stems from the concerned subsystems of the society (economy, law, politics, science, along with others) by means of a variety of legislative products, public policies, alliances, and legal and other scientific communications that emerge as coordinating mechanisms among the alluded major subsystems. 相似文献
