Mental well-being in the religious and the non-religious: evidence for a curvilinear relationship

Previous studies demonstrating a positive relationship between religiosity and mental health have sampled from a highly religious general population with little differentiation between weak religiosity and non-religiosity. Church members are typically compared with non-religious unaffiliated individuals, thus confounding belief with group effects (e.g. social support). The present study examined mental well-being, utilising the full range of certainty of belief or non-belief in God. In the first study, we compared church and secular group members on measures of life satisfaction and emotional stability. The second study used a large survey of the non-religious. A curvilinear relationship was found such that those with higher belief certainty (both confidently religious and atheists) have greater well-being relative to those with low certainty (unsure and agnostics). Multiple regressions controlling for social and demographic variables reduced, but did not eliminate this curvilinear relationship. Mechanisms of well-being may involve a confident worldview rather than religious beliefs themselves.     

The effect of goal setting on group performance: a meta-analysis

Updating and extending the work of O'Leary-Kelly, Martocchio, and Frink (1994), with this meta-analysis on goal setting and group performance we show that specific difficult goals yield considerably higher group performance compared with nonspecific goals (d = 0.80 ± 0.35, k = 23 effect sizes). Moderately difficult and easy goals were also associated with performance benefits relative to nonspecific goals, but these effects were smaller. The overall effect size for all group goals was d = 0.56 ± 0.19 (k = 49). Unexpectedly, task interdependence, task complexity, and participation did not moderate the effect of group goals. Our inventory of multilevel goals in interdependent groups indicated that the effect of individual goals in groups on group performance was contingent upon the focus of the goal: "Egocentric" individual goals, aimed at maximizing individual performance, yielded a particularly negative group-performance effect (d = -1.75 ± 0.60, k = 6), whereas "groupcentric" goals, aimed at maximizing the individual contribution to the group's performance, showed a positive effect (d = 1.20 ± 1.03, k = 4). These findings demonstrate that group goals have a robust effect on group performance. Individual goals can also promote group performance but should be used with caution in interdependent groups. Future research might explore the role of multilevel goals for group performance in more detail. The striking lack of recent field studies in organizational settings that emerged from our brief review of trends in group goal-setting research should be taken into account when designing future studies in this domain.     

When and for whom does crying improve mood? A daily diary study of 1004 crying episodes

We aimed to examine the connections between individual affective characteristics and crying, and to evaluate Rottenberg, Bylsma, and Vingerhoets’ (2008) framework for studying crying and mood. We analyzed the relationship among features of the social environment, mood characteristics of the crier, crying frequency/urge to cry, and mood change across 1004 detailed crying episodes sampled from 97 females. Urge to cry and crying frequency were associated with poorer mood, and urge to cry was associated with greater mood variability. Poorer mood was observed both before and after crying episodes, and one-third of crying episodes resulted in reported mood improvement following crying. Benefits of crying, when they occur, are shaped by the social environment and the affective characteristics of the crier.     

Nostalgic recollections of high and low narcissists

Two functions of nostalgia are consistently documented in the literature: self-positivity and social connectedness. These reflect agency and communion, respectively. Such dimensions are polarized no more than in narcissists, who are high in agency and low in communion. In three studies we tested whether high and low narcissists differ in the content of nostalgic recollections, whether they become nostalgic about different objects, and whether nostalgia serves different functions for them. High (versus low) narcissists made more agentic references in their narratives and manifested nostalgic proclivity toward agentic objects. Furthermore, nostalgia served a self-positivity function, but not a social connectedness function, for high (versus low) narcissists. Findings highlight the relevance of personality—narcissism, in particular—for the experience of nostalgia.     

Stress or no stress: mineralocorticoid receptors in the forebrain regulate behavioral adaptation

Corticosteroid effects on cognitive abilities during behavioral adaptation to stress are mediated by two types of receptors. While the glucocorticoid receptor (GR) is mainly involved in the consolidation of memory, the mineralocorticoid receptor (MR) mediates appraisal and initial responses to novelty. Recent findings in humans and mice suggest that under stress, the MR might be involved in the use of different learning strategies. Here, we used male mice lacking the MR in the forebrain (MR(CaMKCre)), which were subjected to 5-10 min acute restraint stress, followed 30 min later by training trials on the circular hole board. Mice had to locate an exit hole using extra- and intra-maze cues. We assessed performance and the use of spatial and stimulus-response strategies. Non-stressed MR(CaMKCre) mice showed delayed learning as compared to control littermates. Prior stress impaired performance in controls, but did not further deteriorate learning in MR(CaMKCre) mice. When stressed, 20-30% of both MR(CaMKCre) and control mice switched from a spatial to a stimulus-response strategy, which rescued performance in MR(CaMKCre) mice. Furthermore, MR(CaMKCre) mice showed increased GR mRNA expression in all CA areas of the hippocampus and an altered basal and stress-induced corticosterone secretion, which supports their role in the modulation of neuroendocrine activity. In conclusion, our data provide evidence for the critical role of MR in the fast formation of spatial memory. In the absence of forebrain MR spatial learning performance was under basal circumstances impaired, while after stress further deterioration of performance was rescued by switching behavior increasingly to a stimulus-response strategy.     

"Heartwarming memories: Nostalgia maintains physiological comfort": Correction to Zhou et al. (2012)

Reports an error in "Heartwarming Memories: Nostalgia Maintains Physiological Comfort" by Xinyue Zhou, Tim Wildschut, Constantine Sedikides, Xiaoxi Chen and Ad J. J. M. Vingerhoets (Emotion, Advanced Online Publication, Mar 5, 2012, np). In the article, the last sentence was incorrect. The corrected sentence is provided in the erratum. (The following abstract of the original article appeared in record 2012-05385-001.) Nostalgia, a sentimental longing or wistful affection for the past, is a predominantly positive and social emotion. Recent evidence suggests that nostalgia maintains psychological comfort. Here, we propose, and document in five methodologically diverse studies, a broader homeostatic function for nostalgia that also encompasses the maintenance of physiological comfort. We show that nostalgia-an emotion with a strong connotation of warmth-is triggered by coldness. Participants reported stronger nostalgia on colder (vs. warmer) days and in a cold (vs. neutral or warm) room. Nostalgia, in turn, modulates the interoceptive feeling of temperature. Higher levels of music-evoked nostalgia predicted increased physical warmth, and participants who recalled a nostalgic (vs. ordinary autobiographical) event perceived ambient temperature as higher. Finally, and consistent with the close central nervous system integration of temperature and pain sensations, participants who recalled a nostalgic (vs. ordinary autobiographical) event evinced greater tolerance to noxious cold.

Dimensions of perception of posture in dance

This study reports a preliminary investigation designed to assess the possibility of using a semantic differential in the appraisal of expressive characteristics of posture in dance.Twenty still photographs of postures displayed by one female dancer were judged on 25 bipolar scales by 50 Ss. Ratings of eight of these Ss were used for estimating reliabilities of the scales — resulting in elimination of five scales. Intercorrelation matrices of the 20 remaining scales were obtained for each of the 42 remaining Ss. Consideration of homogeneity of the distribution of these matrices led to the exclusion of four of them, leaving 38 matrices for further analysis.After random division of these matrices into two equally sized subgroups, principal component analyses with VARIMAX rotation were carried out on the average intercorrelation matrix for each subgroup. This resulted in two very similar three-factor solutions. The three factors, identified as similar to Osgood's well-known factors of activity, evaluation and potency, accounted for about 55% of the total variance. The results, discussed in terms of Berlyne's conception, suggest that the semantic differential may be a reliable instrument for measuring connotations of posture in dance.     

Dexamethasone Does Not Prevent Seven-Day ADX-Induced Apoptosis in the Dentate Gyrus of the Rat Hippocampus

Long-term adrenalectomy (ADX) is known to result in apoptosis within the dentate gyrus of the rat hippocampus. While the underlying mechanism is still unclear, adrenal steroids appear to play a pivotal role in granule cell survival, as administration of the mineralocorticoid receptor (MR) agonists, corticosterone and aldosterone, to ADX rats results in protection against the ADX-induced effect. The consequence of administration of the glucocorticoid receptor (GR) agonists, dexamethasone and RU28362, however, is less clear, and either complete or only partial protection for the ADX animal has been reported. This study investigated further the role played by GR in the degenerative process. After establishing the characteristics of seven-day ADX-induced apoptosis in the young male Wistar rat, the effect of chronically-implanted, subcutaneous pellets containing various doses of dexamethasone and corticosterone, on ADX-induced apoptosis was studied. Both high and low doses of corticosterone were found to be protective. In contrast to some other studies, however, neither dose of dexamethasone had any obvious protective effect and rather seemed to increase apoptosis in dentate gyrus of intact animals. Intracerebroventricular infusion of dexamethasone for seven days was also found to be ineffective in preventing apoptosis, demonstrating that it is occupation of MR, rather than GR, which is crucial to dentate gyrus granule cell survival.     

Colonic sensitivity in irritable bowel syndrome and normal subjects according to their hemispheric preference and cognitive style.

According to our earlier results, non-painful, weak afferent visceral signals may exert a steady influence on brain processes, including cognitive functions. In the present series colonic impulses of irritable bowel syndrome (IBS) subjects served as a model of chronic impact from the gut. Hemispheric preference, as well as cognitive style of information processing served as indicators of covert changes in brain functions. In twenty-one IBS patients and in ten control subjects of both sexes, the thresholds of minimal colonic distension sensitivity has been measured following the determination of hemispheric preference and of advantage in verbal or spatial information processing of the subjects. In IBS patients distension thresholds proved to be higher in verbals than in spatials, whereas in healthy controls the relationship of colonic thresholds and verbal versus spatial advantage was reversed. Among the normal controls with left hemisphere preference a significantly higher distension threshold has been observed than in those with right hemisphere preference, whereas in the IBS group such threshold-differences were not observable.
