The Multidimensional Existential Meaning Scale: A tripartite approach to measuring meaning in life

To address conceptual difficulties and advance research on meaning in life (MIL), it may be useful to adopt a tripartite view of meaning as consisting of comprehension, purpose, and mattering. This paper discusses the development of the Multidimensional Existential Meaning Scale (MEMS), which explicitly assesses these three subconstructs. Results from three samples of undergraduates showed the MEMS to have favorable psychometric properties (e.g. good factor structure and reliability) and demonstrated that it can effectively differentiate the three subconstructs of meaning. Regression and relative importance analyses showed that each MEMS subscale carried predictive power for relevant variables and other meaning measures. Additionally, the MEMS subscales demonstrated theoretically consistent, differential associations with other variables (e.g. dogmatism, behavioral activation, and spirituality). Overall, results suggest that the MEMS may offer more conceptual precision than existing measures, and it may open new avenues of research and facilitate a more nuanced understanding of MIL.     

The aftermath of memory retrieval for recycling visual working memory representations

We examined the aftermath of accessing and retrieving a subset of information stored in visual working memory (VWM)—namely, whether detection of a mismatch between memory and perception can impair the original memory of an item while triggering recognition-induced forgetting for the remaining, untested items. For this purpose, we devised a consecutive-change detection task wherein two successive testing probes were displayed after a single set of memory items. Across two experiments utilizing different memory-testing methods (whole vs. single probe), we observed a reliable pattern of poor performance in change detection for the second test when the first test had exhibited a color change. The impairment after a color change was evident even when the same memory item was repeatedly probed; this suggests that an attention-driven, salient visual change made it difficult to reinstate the previously remembered item. The second change detection, for memory items untested during the first change detection, was also found to be inaccurate, indicating that recognition-induced forgetting had occurred for the unprobed items in VWM. In a third experiment, we conducted a task that involved change detection plus continuous recall, wherein a memory recall task was presented after the change detection task. The analyses of the distributions of recall errors with a probabilistic mixture model revealed that the memory impairments from both visual changes and recognition-induced forgetting are explained better by the stochastic loss of memory items than by their degraded resolution. These results indicate that attention-driven visual change and recognition-induced forgetting jointly influence the “recycling” of VWM representations.     

How does perfectionism affect academic achievement? Examining the mediating role of accurate self-assessment

Perfectionism, a multidimensional disposition encompassing both positive and negative attributes, has been widely examined in a number of different fields, one of which is academics. However, results of research on the precise connection between perfectionism and academic success remain largely inconclusive. The present study, therefore, attempted to identify this underlying mechanism by examining the mediating role of accurate self-assessment in the relationship between perfectionism and academic achievement of college students. The results revealed that while perfectionistic concerns and strivings did not directly affect academic achievement, their indirect effects were statistically significant. Perfectionistic concerns negatively predicted academic achievement through inaccurate self-assessment, whereas perfectionistic strivings positively predicted academic achievement through accurate self-assessment. These findings are expected to promote a practical and balanced understanding of academic perfectionism by explaining the relationship between the sub-dimensions of perfectionism and academic achievement.     

Group Well-Being: Morale from a Positive Psychology Perspective

What makes life most worth living? The simplest summary of findings from the new field of positive psychology is that other people matter. It is within groups that we live, work, love, and play, and groups should therefore be a primary focus of researchers interested in health and well-being. In the present article, we propose morale as an important indicator of group well-being. We survey what is known about overall morale across a variety of groups: its meaning, measurement, enabling factors, and putative consequences. We sketch a future research agenda that would examine morale in multidimensional terms at both the individual and group levels and would pay particular attention to the positive outcomes associated with morale.
Qu'est-ce qui fait que la vie vaut le plus la peine d'être vécue? Réduire à leur plus simple expression les résultats de ce nouveau domaine qu'est la psychologie positive revient à mentionner l'importance d'autrui. C'est dans des groupes que nous vivons, travaillons, aimons et jouons, et les groupes devraient donc être une préoccupation première pour les chercheurs concernés par la santé et le bien-être. Dans cet article, on avance l'idée que le moral est un indicateur majeur du bien-être des groupes. On recense ce qui est connu sur le moral en général dans divers types de groupes: sa signification, sa mesure, ses antécédents et ses conséquences supposées. On esquisse un futur programme de recherche qui appréhenderait le moral de façon multidimensionnelle aux niveaux à la fois individuel et groupal et accorderait une attention particulière aux retombées positives relevant du moral.     

Death without God: religious struggle, death concerns, and depression in the terminally ill

ABSTRACT— Religious worldviews often provide comfort near the end of life, but they can cause distress if life circumstances are perceived as evidence of God's disfavor. This study, the first to test terror management theory (TMT) with terminally ill participants, examined the hypothesis that concerns about death mediate the relationship between religious struggle (and religious comfort) and depression in the terminally ill. Ninety-eight patients with end-stage congestive heart failure (CHF) completed measures of religious comfort, religious struggle, belief in an afterlife, concerns about death, and depression. In separate hierarchical linear regression models that controlled for degree of belief in an afterlife, death concerns fully mediated the relationships between religious struggle and depression and between religious comfort and depression. These findings suggest that religious struggle is a breakdown in the terror management system that leaves the individual vulnerable to the terror of death, and that properly functioning religious worldviews offer comfort by buffering the individual against death concerns.     

Acute predator stress impairs the consolidation and retrieval of hippocampus-dependent memory in male and female rats

We have studied the effects of an acute predator stress experience on spatial learning and memory in adult male and female Sprague-Dawley rats. All rats were trained to learn the location of a hidden escape platform in the radial-arm water maze (RAWM), a hippocampus-dependent spatial memory task. In the control (non-stress) condition, female rats were superior to the males in the accuracy and consistency of their spatial memory performance tested over multiple days of training. In the stress condition, rats were exposed to the cat for 30 min immediately before or after learning, or before the 24-h memory test. Predator stress dramatically increased corticosterone levels in males and females, with females exhibiting greater baseline and stress-evoked responses than males. Despite these sex differences in the overall magnitudes of corticosterone levels, there were significant sex-independent correlations involving basal and stress-evoked corticosterone levels, and memory performance. Most importantly, predator stress impaired short-term memory, as well as processes involved in memory consolidation and retrieval, in male and female rats. Overall, we have found that an intense, ethologically relevant stressor produced a largely equivalent impairment of memory in male and female rats, and sex-independent corticosterone-memory correlations. These findings may provide insight into commonalities in how traumatic stress affects the brain and memory in men and women.     

Effects of study task on the neural correlates of source encoding

The present study investigated whether the neural correlates of source memory vary according to study task. Subjects studied visually presented words in one of two background contexts. In each test, subjects made old/new recognition and source memory judgments. In one study test cycle, study words were subjected to animacy judgments, whereas in another cycle the study task required syllable judgments. Functional magnetic resonance imaging (fMRI) was employed to contrast the neural activity elicited by study words that attracted accurate source judgments on the later memory test, as opposed to words for which source judgments were incorrect or for which source information was unavailable. In both tasks, relative to words for which source memory failed, study words that were later assigned to the correct source elicited enhanced activity in ventral extrastriate cortex. In addition to these common effects of subsequent source memory, additional effects were observed that were selective for each study task. The present findings add weight to the proposal that neural activity supporting successful episodic memory encoding is a reflection of both the online processing engaged by an episode as it is experienced, and the demands imposed by the later retrieval task.
