Do Trust-Based Beliefs Mediate the Associations of Frequency of Private Prayer with Mental Health? A Cross-Sectional Study

Significant associations of private prayer with mental health have been found, while mechanisms underlying these associations are largely unknown. This cross-sectional online study (N = 325, age 35.74, SD 18.50, 77.5 % females) used path modeling to test if trust-based beliefs (whether, when, and how prayers are answered) mediated the associations of prayer frequency with the Anxiety, Confusion, and Depression Profile of Mood States-Short Form scales. The association of prayer and depression was fully mediated by trust-based beliefs; associations with anxiety and confusion were partially mediated. Further, the interaction of prayer frequency by stress was associated with anxiety.     

Thyme to touch: Infants possess strategies that protect them from dangers posed by plants

Plants have been central to human life as sources of food and raw materials for artifact construction over evolutionary time. But plants also have chemical and physical defenses (such as harmful toxins and thorns) that provide protection from herbivores. The presence of these defenses has shaped the behavioral strategies of non-human animals. Here we report evidence that human infants possess strategies that would serve to protect them from dangers posed by plants. Across two experiments, infants as young as eight months exhibit greater reluctance to manually explore plants compared to other entities. These results expand the growing literature showing that infants are sensitive to certain ancestrally recurrent dangers, and provide a basis for further exploration.     

Reflexive orienting in response to short- and long-duration gaze cues in young,young-old,and old-old adults

Shifting visual focus on the basis of the perceived gaze direction of another person is one form of joint attention. In the present study, we investigated whether this socially relevant form of orienting is reflexive and whether it is influenced by age. Green and Woldorff (Cognition 122:96–101, 2012) argued that rapid cueing effects (i.e., faster responses to validly than to invalidly cued targets) were limited to conditions in which a cue overlapped in time with a target. They attributed slower responses following invalid cues to the time needed to resolve the incongruent spatial information provided by the concurrently presented cue and target. In the present study, we examined the orienting responses of young (18–31 years), young-old (60–74 years), and old-old (75–91 years) adults following uninformative central gaze cues that overlapped in time with the target (Exp. 1) or that were removed prior to target presentation (Exp. 2). When the cue and target overlapped, all three groups localized validly cued targets more quickly than invalidly cued targets, and validity effects emerged earlier for the two younger groups (at 100 ms post-cue-onset) than for the old-old group (at 300 ms post-cue-onset). With a short-duration cue (Exp. 2), validity effects developed rapidly (by 100 ms) for all three groups, suggesting that validity effects resulted from reflexive orienting based on the gaze cue information rather than from cue–target conflict. Thus, although old-old adults may be slow to disengage from persistent gaze cues, attention continues to be reflexively guided by gaze cues late in life.     

Continuous flash suppression and monocular pattern masking impact subjective awareness similarly

Peters and Lau (eLife, 4, e09651, 2015) found that when criterion bias is controlled for, there is no evidence for unconscious visual perception in normal observers, in the sense that they cannot directly discriminate a target above chance without knowing it. One criticism of that study is that the visual suppression method used, forward and backward masking (FBM), may be too blunt in the way it interferes with visual processing to allow for unconscious forced-choice discrimination. To investigate this question, we compared FBM directly to continuous flash suppression (CFS) in a two-interval forced-choice task. Although CFS is popular, and may be thought of as a more powerful visual suppression technique, we found no difference in the degree of perceptual impairment between the two suppression types. To the extent that CFS impairs perception, both objective discrimination and subjective awareness are impaired to similar degrees under FBM. This pattern was consistently observed across three experiments in which various experimental parameters were varied. These findings provide evidence for an ongoing debate about unconscious perception: normal observers cannot perform forced-choice discrimination tasks unconsciously.     

Benefits of team participative decision making and its potential to affect individual creativity

How does team participative decision‐making affect individual creative performance? Building on team climate theory (Anderson & West, 1998; West 1990, 2002; West & Sacramento, 2012), this study investigates the indirect effect of team participative decision making on employee creativity through individual perception of cognition team diversity and psychological safety. Results from 256 supervisor–subordinate dyads in 45 teams show that team participative decision making is positively associated with cognitive team diversity and psychological safety. For the mediating effects, team participative decision‐making climate is positively indirectly related to creative performance via psychological safety but not via cognitive team diversity. Theoretical and practical implications are discussed.     

Nature Gives Us Strength: Exposure to Nature Counteracts Ego-Depletion

Previous research rarely investigated the role of physical environment in counteracting ego-depletion. In the present research, we hypothesized that exposure to natural environment counteracts ego-depletion. Three experiments were conducted to test this hypothesis. In Experiment 1, initially depleted participants who viewed pictures of nature scenes showed greater persistence on a subsequent anagram task than those who were given a rest period. Experiment 2 expanded upon this finding by showing that natural environment enhanced logical reasoning performance after ego-depleting task. Experiment 3 adopted a two- (depletion vs. no-depletion) -by-two (nature exposure vs. urban exposure) factorial design. We found that nature exposure moderated the effect of depletion on anagram task performance. Taken together, the present studies offer a viable and novel strategy to mitigate the negative impacts of ego-depletion.     

The Community Story,Relationality and Process: Bridging Tools for Researching Local Knowledge in a Peri‐urban Township

In intervening in social challenges impacting local communities, Western forms of dispute/conflict resolution have been critiqued for imparting norms, values and practices that marginalise worldviews of indigenous people. From a decolonizing stance, indigenous scholars have emphasised the need for recovery of ‘lost’ values, beliefs and practices to advance indigenous knowledge. We highlight some of the conceptual challenges associated with applying ‘indigenous knowledge’ and culture‐specific ‘indigenous methodologies’ to a marginalised peri‐urban, ethnically plural township community situated on the outskirts of Johannesburg, South Africa. In embracing the mutuality of indigenous and Western knowledge forms, we explore three elements: the community story, relationality and process in relation to initial engagements with our study community. We attempt to transcend the dualism between ‘Western’ epistemologies and ‘indigenous knowledge’ through these ‘bridging concepts’. What is offered is not a formula or model but an orientation that aims to foster mutual learning through collaborative partnerships within and between communities and researchers with a view to inspiring possibilities for creative and meaningful solutions for violence prevention and dispute/conflict resolution.

Rehearsal in serial memory for visual-spatial information: Evidence from eye movements

It is well established that rote rehearsal plays a key role in serial memory for lists of verbal items. Although a great deal of research has informed us about the nature of verbal rehearsal, much less attention has been devoted to rehearsal in serial memory for visual-spatial information. By using the dot task—a visual-spatial analogue of the classical verbal serial recall task—with delayed recall, performance and eyetracking data were recorded in order to establish whether visual-spatial rehearsal could be evidenced by eye movement. The use of eye movement as a form of rehearsal is detectable (Experiment 1), and it seems to contribute to serial memory performance over and above rehearsal based on shifts of spatial attention (Experiments 1 and 2).     

Backward recall and benchmark effects of working memory

Working memory was designed to explain four benchmark memory effects: the word length effect, the irrelevant speech effect, the acoustic confusion effect, and the concurrent articulation effect. However, almost all research thus far has used tests that emphasize forward recall. In four experiments, we examine whether each effect is observable when the items are recalled in reverse order. Subjects did not know which recall direction would be required until the time of test, ensuring that encoding processes would be identical for both recall directions. Contrary to predictions of both the primacy model and the feature model, the benchmark memory effect was either absent or greatly attenuated with backward recall, despite being present with forward recall. Direction of recall had no effect on the more difficult conditions (e.g., long words, similar-sounding items, items presented with irrelevant speech, and items studied with concurrent articulation). Several factors not considered by the primacy and feature models are noted, and a possible explanation within the framework of the SIMPLE model is briefly presented.     

A Tale of Two Generations: Creativity Growth and Gender Differences Over a Period of Education and Curriculum Reforms

The Wallach–Kogan Creativity Tests were translated into Chinese and later fully computerized for research in Hong Kong. The normative data of two cohorts (1994 and 2002) of school children were employed to test the hypothesis that growth in creative thinking occurs in a society or culture during a period of education and curriculum reforms that emphasize creative thinking. Results of multivariate analysis of variance and subsequent univariate analysis of variance supported the hypothesis. Moreover, some interesting gender differences in creativity growth were observed, underlining the fact that boys and girls should be treated differentially to obtain a desirable creativity growth for them.
