The development of generosity and moral cognition across five cultures

Morality is an evolved aspect of human nature, yet is heavily influenced by cultural environment. This developmental study adopted an integrative approach by combining measures of socioeconomic status (SES), executive function, affective sharing, empathic concern, theory of mind, and moral judgment in predicting sharing behavior in children (N = 999) from the age of 5 to 12 in five large‐scale societies: Canada, China, Turkey, South Africa, and the USA. Results demonstrate that age, gender, SES, culture, and social cognitive mechanisms explain over 20% of the variance worldwide in children's resource allocation. These findings are discussed in reference to standard cultural comparisons (individualist/collectivist), as well as the degree of market integration, and highlight continuities and discontinuities in children's generosity across urban contexts.     

Building and sustaining work engagement – a participatory action intervention to increase work engagement in nursing staff

This study evaluated whether a participatory action research intervention with nursing staff on acute care older people National Health Service wards in the United Kingdom was effective for increasing work engagement. Mediation analyses between job resources (social support, influence in decision-making), job demands, work-related needs (autonomy, competence, relatedness), and work engagement explored the presumed psychological mechanisms underlying the intervention. A non-randomized, matched control group, pretest, post-test design involved three intervention and five control wards. A significant decrease in relatedness, and a borderline significant decrease in competence, was observed in the intervention group compared to the control group, with no effect on work engagement (N = 45). Work-related needs mediated between resources and work engagement, supporting the job demands-resources model and self-determination theory as an underlying explanatory theory. Intervention implementation was difficult, highlighting the need for participant and organizational readiness for change, and strong management support. This is the first known study to apply participatory techniques to increase work engagement in nursing staff and explore the underlying explanatory psychological mechanisms, offering a novel means of taking work engagement research forward. Crucially, it highlights the challenges involved in intervention research and the importance of including evaluations of intervention implementation alongside statistical evaluations to avoid erroneous conclusions.     

Multiple studies and weak evidential defeat

When a study shows statistically significant correlation between an exposure and an outcome, the credence of a real connection between the two increases. Should that credence remain the same when it is discovered that further independent studies between the exposure and other independent outcomes were conducted? Matthew Kotzen argues that it should remain the same, even if the results of those further studies are discovered. However, we argue that it can differ dependent upon the results of the studies.     

MMPI-2 as a predictor of change in PTSD symptom clusters: a further analysis of the Forbes et al. (2002) data set

In this study, we reanalyzed the Forbes et al. (2002) data set to examine the Minnesota Multiphasic Personality Inventory (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) as a differential predictor of change across posttraumatic stress disorder symptom clusters following treatment in 141 Vietnam veterans. A series of partial correlation and linear multivariate regression analyses, controlling for initial symptom severity, identified several scales predictive of symptom change. None of the MMPI-2 scales, however, emerged as predictors of change in reexperiencing symptoms. Social alienation and marital distress were the most potent predictors for avoidance symptoms. Anger, alcohol use, and hypomania were the most potent predictors for the hyperarousal symptoms. Of the personality disorders, borderline personality was the strongest predictor of change in the avoidance and hyperarousal clusters. Further replication of the findings of this article and those reported by Forbes et al. (2002) is required.     

Practice effects on motor control in healthy seniors and patients with mild cognitive impairment and Alzheimer's disease

This research was designed to test the hypothesis that motor practice can enhance the capabilities of motor control in healthy controls (NC) and patients with a diagnosis of probable Alzheimer's disease (AD) and mild cognitive impairment (MCI), and consequently results in better motor performance. Approximately half of the subjects in the NC (n = 31), AD (n = 28), and MCI (n = 29) either received or did not receive practice on a task of fast and accurate arm movement with a digitizer. Changes in movement time (MT), movement smoothness (jerk), and percentage of primary submovement (PPS) were recorded and compared among the three groups across six blocks of trials (baseline and five training sessions). For all subjects, practice improved motor functions as reflected by faster and smoother motor execution, as well as a greater proportion of programming control. Compared to unaffected matched controls, AD and MCI subjects exhibited a greater reduction in movement jerk due to practice. Movement time and PPS data revealed that motor practice appeared to reduce the use of "on-line" correction adopted by the AD or MCI patients while performing the aiming movements. Evidently, their arm movements were quicker, smoother, and temporally more consistent than their untrained peers. The findings of this study shed light on how MCI and AD may affect motor control mechanisms, and suggest possible therapeutic interventions aimed at improving motor functioning in these impaired individuals.     

The MMPI-2 as a predictor of symptom change following treatment for posttraumatic stress disorder

This study sought to examine the impact of personality factors on symptom change following treatment for 141 Vietnam veterans with chronic combat-related posttraumatic stress disorder (PTSD) using the Minnesota Multiphasic Personality Inventory-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989). A series of partial correlation and linear multivariate regression analyses identified social alienation, associated with anger and substance use, as the most potent negative predictor of symptom change. Of the scales assessing personality disorder, Borderline Personality was identified as the strongest negative predictor of outcome. Regression analyses examining the most salient scales identified 5 items that contributed 14% of the variance in the prediction of change scores independently of the 21% accounted for by pretreatment PTSD severity.     

Body Without End: Biological Mutualism and the Body of Christ

This article argues that the ecological turn towards biological mutualism enlivens our understanding of the eschatological promise contained in Christ’s resurrected and ascended body. I examine the implications of proposing that Christ’s body was not only incarnate as microbiome, but also rose and ascended as microbiome. First, I analyse contemporary approaches to Christology’s relation to creation and Andrew Davison’s theological exploration of mutualism. I then respond via Irenaeus’ defence of Christ’s bodily resurrection and ascension as promise for all flesh. By reading Irenaeus in light of the mutualistic body, we enrich our understanding of this promise: of fruitfulness for all creation, of fullness for human nature, and that fleshly life is no ultimate barrier to union with God. Finally, I propose that this reading also offers renewed insight into the Eucharist: this promise and its implications are also made manifest at the heart of the church, Christ’s body on earth.     

The Scientist and the Artist: adaptive dissociation within the HIV-positive population

This paper reports on the findings of two independent qualitative studies which were conducted with HIV-positive cohort over a period of 2010–2012. Although the original studies used different qualitative designs (IPA and Grounded Theory), the authors have nevertheless sought to explore the combined utility of their findings by using a broad stance of phenomenological enquiry. The authors argue that evidence of a particular dissociative pattern in their accounts of an HIV-related experience is present in the contributors' narrative. Dissociation in this context occurred not in personality but between different or discrete mental faculties such as memory, emotions, perceptions and thought. It was suggested that it serves adaptive function and therefore could be utilised in clinical work when appropriate.
