Strength-Based Positive Interventions: Further Evidence for Their Potential in Enhancing Well-Being and Alleviating Depression

The impact of nine strengths-based positive interventions on well-being and depression was examined in an Internet-based randomized placebo-controlled study. The aims of the study were to: (1) replicate findings on the effectiveness of the gratitude visit, three good things, and using character strengths interventions; (2) test variants of interventions (noting three good things for 2 weeks; combining the gratitude visit and three good things interventions; and noting three funny things for a week); and (3) test the effectiveness of the counting kindness, gift of time, and another door opens-interventions in an online setting. A total of 622 adults subjected themselves to one of the nine interventions or to a placebo control exercise (early memories) and thereafter estimated their degrees of happiness and depression at five times (pre- and post-test, 1-, 3-, and 6 months follow-up). Eight of the nine interventions increased happiness; depression was decreased in all groups, including the placebo control group. We conclude that happiness can be enhanced through some “strengths-based” interventions. Possible mechanisms for the effectiveness of the interventions are discussed.     

Saving-enhanced performance: saving items after study boosts performance in subsequent cognitively demanding tasks

ABSTRACT

By saving and storing information, we use digital devices as our external memory stores, being able to offload and temporarily forget saved contents. Storm and Stone [2015. Saving-enhanced memory: The benefits of saving on the learning and remembering of new information. Psychological Science, 26(2), 182–188] showed that such memory offloading can be beneficial for subsequent memory performance. Saving already encoded items enhanced recall of items encoded after saving. In the present study, we did not only replicate saving-enhanced memory but found saving-enhanced performance for unrelated cognitively demanding tasks. Participants solved more modular arithmetic problems when they were able to offload a previously studied word list, compared to trials without the possibility to offload. Thus, saving of recently encoded items entailed a general benefit on subsequent cognitive performance, beyond encoding and retrieving word lists. We assume that offloading frees participants from the need to maintain offloaded items. Gained resources can then be used for subsequent tasks with high cognitive demands. In a nutshell, memory offloading can help to reduce the amount of information that has to be processed at a given time, efficiently delegating our limited cognitive resources to the most relevant tasks at hand while currently irrelevant information are safely stored outside our own memory.     

Hosts and Guests: Hospitality as an Emerging Paradigm in Mission

In recent years, hospitality has turned into a central term in missiological discussions integrating several aspects of missiological reflection. The essay summarizes how the dialectic between host and guest builds a central thread throughout the biblical narrative and explores how the dual role of missionaries as hosts and guests opens new dimensions of missionary existence and self‐understanding. On the one hand, the role of the missionary as guest emphasizes the missionary's vulnerability and voluntary submission to the cultural and contextual rules. It thus implies a humility that stands in contrast to any spirit of conquest. On the other hand, missionaries who understand their role as one of host show a readiness for disruption and openness to the sacramental quality of a guest that possibly allows an encounter with God. Hospitality thus re‐enacts a basic movement of faith, the movement of receiving the alien word of God. In a final reflection, the essay considers a contradiction inherent in the concept of hospitality, as pointed out by the French philosopher Jacques Derrida, the contradiction between openness to those in need of hospitality and the host's dependence on power and control in order to host people.     

Disaster threat and justice sensitivity: a terror management perspective

Based on terror management theory, we tested the idea that reminders of death strengthen justice sensitivity. In Study 1, we exposed participants to three different kinds of death‐related pictures (terrorism vs. natural disasters vs. graveyards) or neutral pictures. The results showed that death‐related visual material led to more justice sensitivity from three perspectives (victim, observer, and perpetrator) than neutral visual material. Likewise, Study 2 indicated that fake newspaper articles claiming that the likelihood of terrorism is very high (vs. low) strengthened these three justice sensitivity types. Theoretical and practical implications are discussed.     

Performing a secondary executive task with affective stimuli interferes with decision making under risk conditions

Previous studies demonstrated that executive functions are crucial for advantageous decision making under risk and that therefore decision making is disrupted when working memory capacity is demanded while working on a decision task. While some studies also showed that emotions can affect decision making under risk, it is unclear how affective processing and executive functions predict decision-making performance in interaction. The current experimental study used a between-subjects design to examine whether affective pictures (positive and negative pictures compared to neutral pictures), included in a parallel executive task (working memory 2-back task), have an impact on decision making under risk as assessed by the Game of Dice Task (GDT). Moreover, the performance GDT plus 2-back task was compared to the performance in the GDT without any additional task (GDT solely). The results show that the performance in the GDT differed between groups (positive, negative, neutral, and GDT solely). The groups with affective pictures, especially those with positive pictures in the 2-back task, showed more disadvantageous decisions in the GDT than the groups with neutral pictures and the group performing the GDT without any additional task. However, executive functions moderated the effect of the affective pictures. Regardless of affective influence, subjects with good executive functions performed advantageously in the GDT. These findings support the assumption that executive functions and emotional processing interact in predicting decision making under risk.     

Article retracted,but the message lives on

The retraction of an original article aims to ensure that readers are alerted to the fact that the findings are not trustworthy. However, the present research suggests that individuals still believe in the findings of an article even though they were later told that the data were fabricated and that the article was retracted. Participants in a debriefing condition and a no-debriefing condition learned about the scientific finding of an empirical article, whereas participants in a control condition did not. Afterward, participants in the debriefing condition were told that the article had been retracted because of fabricated data. Results showed that participants in the debriefing condition were less likely to believe in the findings than participants in the no-debriefing condition but were more likely to believe in the findings than participants in the control condition, suggesting that individuals do adjust their beliefs in the perceived truth of a scientific finding after debriefing—but insufficiently. Mediational analyses revealed that the availability of generated causal arguments underlies belief perseverance. These results suggest that a retraction note of an empirical article in a scientific journal is not sufficient to ensure that readers of the original article no longer believe in the article’s conclusions.     

Interference within hands: Retrieval-induced forgetting of left and right hand movements

We examined retrieval-induced forgetting of motor sequences that were categorized by the effectors (left or right hand) involved in their execution. This left–right categorization was independent from input locations or input devices. In addition, the acquired motor sequences were arbitrarily assigned to left and right. Participants learned twelve sequential joystick movements as responses to letter stimuli. Half of the sequences pertained to the left, half to the right hand. Subsequent retrieval-practice of half the items of one hand induced forgetting for the non-retrieved rest of the items of that hand in a final recall test. This finding demonstrates that the hands were used to organize the memory storage of motor sequences in a way that gave rise to later interference between commonly stored items, that is, linked to the same hand.     

Becoming uniquely human? Comparing chimpanzee to human infancy

Does comparing behavioral development between chimpanzees and humans during infancy hold the key to understanding what is uniquely human? Recent work shows that while many behaviors emerge at similar ages in chimpanzees, human infants develop behavioral traits underpinning our prosocial and ultra-cooperative nature at a much accelerated rate.
