A longitudinal study of a matched sample of 60 recently widowed and 60 married men and women tested predictions from stress and attachment theory regarding the role of social support in adjustment to bereavement. Stress theory predicts a buffering effect, attributing the impact of bereavement on well-being to stressful deficits caused by the loss and assuming that these deficits can be compensated through social support. In contrast, attachment theory denies that supportive friends can compensate the loss of an attachment figure and predicts main effects of marital status and social support. Attachment theory further suggests that marital status and social support influence well-being by different pathways, with the impact of marital status mediated by emotional loneliness and the impact of social support mediated by social loneliness. Results clearly supported attachment theory.

Nostalgia is a frequently-experienced complex emotion, understood by laypersons in the United Kingdom and United States of America to (1) refer prototypically to fond, selfrelevant, social memories and (2) be more pleasant (e.g., happy, warm) than unpleasant (e.g., sad, regretful). This research examined whether people across cultures conceive of nostalgia in the same way. Students in 18 countries across 5 continents (N = 1704) rated the prototypicality of 35 features of nostalgia. The samples showed high levels of agreement on the rank-order of features. In all countries, participants rated previously-identified central (vs. peripheral) features as more prototypical of nostalgia, and showed greater inter-individual agreement regarding central (vs. peripheral) features. Cluster analyses revealed subtle variation among groups of countries with respect to the strength of these pancultural patterns.All except African countries manifested the same factor structure of nostalgia features. In Japan, a woman drives past her childhood school and exclaims how natsukashii it is. In Ethiopia, a musician sings a Tizita ballad reliving memories of a lost lover. In the USA, a man smiles nostalgically as he listens to an old record that reminds him of his carefree teenage years. And in ancient Greece, the mythical hero Odysseus is galvanized by memories of his family as he struggles to make his way home from war (Homer, trans. 1921). To what extent are these four characters experiencing the same emotion? Is nostalgia universal?Growing evidence indicates that nostalgia is a self-relevant emotion associated with fond memories (Hepper, Ritchie, Sedikides, & Wildschut, 2012; and that it serves psychological functions (Routledge, Wildschut, Sedikides, & Juhl, 2013;. If nostalgia qualifies as an emotion and an adaptive psychological resource, it may be pancultural. The present article begins to address this issue by examining the equivalence of prototypical conceptions of nostalgia across a range of cultures. The Universality of EmotionThe universality of emotion concepts has long attracted scholarly attention. Darwin (1872/1965) proposed that emotions evolved as adaptive responses to social living, and thus some emotions should be universal. In contrast, Harré (1986) argued that emotions are primarily cultural constructions and thus should vary according to the meanings and practices of different cultural settings. Although the issues are textured, two major lines of research have supported the universality view. The first line of research has identified universally recognized facial expressions, focusing on a core set of "basic" emotions (e.g., anger, joy, sadness; Ekman, 1992;Ekman & Friesen, 1971;Russell, 1991a). The second line of research has examined conceptions of emotion words (Fontaine, Scherer, Roesch, & Ellsworth, 2007; Kuppens, Ceulemans, Timmerman, Diener, & Kim-Prieto, 2006; Páez & Vegara, 1995). This lexical literature has established that, across cultures, emotion (and specific emotions) is a fuzzy c...

The illusion of group effectivity refers to the belief, persistent despite contradictory empirical evidence, that groups can stimulate creativity. This article uses unpublished data from the authors' research on brainstorming to illustrate the illusion of group effectivity and then presents a theoretical interpretation of this illusion based on two assumptions: (a) People are motivated to view their own performance in a positive light. (b) People who generate ideas in groups have difficulty in differentiating between own and others' ideas. They are therefore more prone to this self-serving bias than persons who work individually. In an experiment conducted to test these hypotheses, subjects who had brainstormed either in groups or individually were presented with the set of ideas produced by their nominal or real groups and asked to identify the ideas they had suggested and those that had occurred to them. Results were generally consistent with the hypotheses.

Previous studies suggested that public trust in government is vital for implementations of social policies that rely on public's behavioural responses. This study examined associations of trust in government regarding COVID-19 control with recommended health behaviours and prosocial behaviours. Data from an international survey with representative samples (N=23,733) of 23 countries were analysed. Specification curve analysis showed that higher trust in government was significantly associated with higher adoption of health and prosocial behaviours in all reasonable specifications of multilevel linear models (median standardised β=0.173 and 0.244, P<0.001). We further used structural equation modelling to explore potential determinants of trust in government regarding pandemic control. Governments perceived as well organised, disseminating clear messages and knowledge on COVID-19, and perceived fairness were positively associated with trust in government (standardised β=0.358, 0.230, 0.055, and 0.250, P<0.01). These results highlighted the importance of trust in government in the control of COVID-19.
