This diary study examines psychological detachment, companionship, and content of conversation during lunch break as predictors of daily vigour after lunch break and at the end of the working day. Drawing on resource regulation theory and the effort recovery model (ERM), we hypothesize that companionship of the supervisor during lunch break is negatively and companionship of colleagues positively related to employee’s daily vigour. The companionship of both, supervisors and colleagues, as well as work-related conversations are hypothesized to decrease psychological detachment during lunch breaks. In total, 71 persons in administrative jobs completed daily surveys over one working week. Results of hierarchical linear modelling showed that psychological detachment is positively related to vigour after lunch break, but unrelated to vigour at the end of the working day. Lunch breaks with the supervisor predicted a lower level of vigour at the end of the working day, but a higher level of vigour after lunch break. Lunch breaks with colleagues were unrelated to vigour after lunch break, but associated with higher vigour at the end of a working day. The companionship of both—colleagues and supervisors—as well as work-related conversation decreased psychological detachment during lunch break. 相似文献

Although humans are usually believed to be prosocial, the evolutionary origins of prosociality are largely debated. One hypothesis is that cooperative breeding has been one major precursor to the emergence of prosociality. In vertebrates, however, experimental evidence of prosociality has been mainly gathered in non-human primates. In this study, we tested the cooperative breeding hypothesis in cooperative breeding meerkats (Suricata suricatta). In particular, we tested whether meerkats take into account partners’ benefits when distributing food rewards. Nine individuals were presented with two platforms baited with different food distributions (providing food to themselves, to a partner or both). In all conditions, the decision to operate the apparatus was based on the presence of food on the subject’s side, and not on the possible benefits to partners. Despite being cooperative breeders, meerkats in this study failed to be prosocial, suggesting that prosociality in this species may be limited to specific contexts. 相似文献

The ability to inhibit unproductive motor responses triggered by salient stimuli is a fundamental inhibitory skill. Such motor self-regulation is thought to underlie more complex cognitive mechanisms, like self-control. Recently, a large-scale study, comparing 36 species, found that absolute brain size best predicted competence in motor inhibition, with great apes as the best performers. This was challenged when three Corvus species (corvids) were found to parallel great apes despite having much smaller absolute brain sizes. However, new analyses suggest that it is the number of pallial neurons, and not absolute brain size per se, that correlates with levels of motor inhibition. Both studies used the cylinder task, a detour-reaching test where food is presented behind a transparent barrier. We tested four species from the order Psittaciformes (parrots) on this task. Like corvids, many parrots have relatively large brains, high numbers of pallial neurons, and solve challenging cognitive tasks. Nonetheless, parrots performed markedly worse than the Corvus species in the cylinder task and exhibited strong learning effects in performance and response times. Our results suggest either that parrots are poor at controlling their motor impulses, and hence that pallial neuronal numbers do not always correlate with such skills, or that the widely used cylinder task may not be a good measure of motor inhibition. 相似文献

Causal reasoning is crucial to people’s decision making in probabilistic environments. It may rely directly on data about covariation between variables (correspondence) or on inferences based on reasonable constraints if larger causal models are constructed based on local relations (coherence). For causal chains an often assumed constraint is transitivity. For probabilistic causal relations, mismatches between such transitive inferences and direct empirical evidence may lead to distortions of empirical evidence. Previous work has shown that people may use the generative local causal relations A → B and B → C to infer a positive indirect relation between events A and C, despite data showing that these events are actually independent (von Sydow et al. in Proceedings of the thirty-first annual conference of the cognitive science society. Cognitive Science Society, Austin, 2009, Proceedings of the 32nd annual conference of the cognitive science society. Cognitive Science Society, Austin, 2010, Mem Cogn 44(3):469–487, 2016). Here we used a sequential learning scenario to investigate how transitive reasoning in intransitive situations with negatively related distal events may relate to betting behavior. In three experiments participants bet as if they were influenced by a transitivity assumption, even when the data strongly contradicted transitivity. 相似文献

Three fundamental types of causal relations are those of necessity, sufficiency, and necessity and sufficiency. These types are defined in contexts of categorical variables or events. Using statement calculus or Boolean algebra, one can determine which patterns of events are in support of a particular form of causal relation. In this article, we approach the analysis of these forms of causality taking the perspective of the analyst of empirical data. It is proposed using Configural Frequency Analysis (CFA) to test hypotheses about type of causal relation. Models are proposed for two-variable and multi-variable cases. Two CFA approaches are proposed. In the first, individual patterns (configurations) are examined under the question whether they are in support of a particular type of causal relation. In the second, patterns that are in support are compared with corresponding patterns that are not in support. In an empirical example, hypotheses are tested on the prediction of sustainability of change in dietary fat intake habits. 相似文献

Our longitudinal study contributes to the body of literature on depression in childhood by examining potential protective factors. We investigated the influence of maternal depressive symptoms on child depressive symptoms at early school age and its gender-specific moderation by children’s narrative representations of the maternal figure, over and above children’s own depressive symptoms at preschool age. Children’s narrative representations were assessed using the MacArthur Story Stem Battery in 170 preschool children (92 girls; 54.1?%) oversampled for internalizing symptoms. Children’s depressive symptoms were assessed at preschool age (Time 1; 4–6 years) and at early school age (Time 2; 6–8 years) by maternal report; mothers’ depressive symptoms were assessed at Time 1. The results showed that for boys, only their own depressive symptoms at Time 1 predicted their depressive symptoms at Time 2. For girls, maternal depressive symptoms were a significant risk factor for their own depressive symptoms at Time 2. Regarding this association, we also found a moderation effect: girls with more positive narrative representations of the maternal figure showed a reduced negative impact of maternal depressive symptoms on their own depressive symptoms at Time 2. This implies that clinical practice should screen a child for early depressive symptoms, especially if the mother displays depressive symptoms. Clinicians might also assess children’s inner working models, which can serve as a protective factor. 相似文献

This study examines associations between parental capacities for triadic (mother–father–child) relationships, assessed prenatally, and the representational and behavioral functioning of their offspring at preschool age. Thirty‐eight parental couples were given an intensive psychodynamic interview during their first pregnancy to assess how they anticipated their future parenthood and their relationships as threesomes (mother–father–child). The capacity for triadic relationships (“triadic capacity”) was defined as the capacity of fathers and mothers to anticipate their family relationships without excluding either themselves or their partners from the relationship with the infant. Four years later, the representational and behavioral functioning of their children were assessed in depth using child narrative interviews and parental behavior ratings. The coherence of the children's narratives and the number of positive themes they expressed were significantly negatively correlated with the number of behavioral problems. In the longitudinal analyses, there were significant positive correlations between the parental triadic capacities and the coherence/number of positive themes in the children's narratives whereas parental triadic capacities showed a significant negative correlation with the number of the children's externalizing problems. The significance of triadic relational family processes for the development of children's representational world and behavioral functioning is discussed. ©2005 Michigan Association for Infant Mental Health. 相似文献
