The human capacity and need for play has been recognized as a central psychotherapeutic component for a long time (e.g. Winnicott 1971). More recently, experts have started developing specialized digital gameplay to be used as therapeutic tools and even utilizing existing videogames for similar purposes (see Ceranoglu 2010). On the other hand, the concerns about some players becoming overinvolved in videogames also led the World Health Organization to include “gaming disorder” in the 11th edition of the International Classification of Diseases, which echoes the nuance required to address human-technology relationships in general.  
 
In the present registered report, Billieux et al. (2023) make use of analog structured role-play in a new intervention aiming to mitigate social anxiety and problematic gaming patterns in online gamers. The authors carry out an exploratory pilot to test a 10-week protocol over three modules inspired by the well-known Dungeons & Dragons franchise. Through multiple single-case design, the authors explore the feasibility of the intervention and its effectiveness on social skills, self-esteem, loneliness, assertiveness, and gaming disorder symptoms.

Shame and guilt are powerful negative emotions that are notable for their external vs. internal focus: while shame is generally experienced in response to public scrutiny, guilt arises from a self-directed, private evaluation. In a formative study, Smith et al. (2002) asked whether the level of public exposure influenced levels of shame and guilt arising from one's transgressions, and found that, compared to private situations, public exposure was more strongly associated with shame than with guilt. Since then, these findings have had significant implications for theories and applications of moral psychology.

 

In the current study, Zhang et al. (2023) directly replicated Smith et al. (2002) in a large online sample, revisiting two critical questions from Study 1: (a) whether public exposure affects the magnitude of shame and guilt over one’s misconduct, and (b) whether stronger moral belief increases guilt and shame over one’s misconduct. The results fail to confirm the original conclusions: both public exposure and manipulation of moral beliefs were found to influence shame and guilt, with no reliable evidence that shame was influenced more strongly than guilt. These findings thus constitute a non-replication and offer a challenge to theoretical models that hinge on the separability of shame and guilt as separate constructs.

A convergence of evidence suggests that early life adversity may cause dysfunction in opioid-sensitive reward systems. Childhood adversity is associated with opioid use, potentially by altering reward and motivation networks, and experimental models in animals have found that early life adversity increases and consolidates opioid seeking behaviours. Further, in a recent controlled experiment, Carlyle et al. (2021) found that opioid administration produced stronger positive responses, and weaker negative responses, in adults with a history of childhood abuse and neglect.

 

In the current study, Carlyle et al. (2023) tested the generalisability of these previous findings in a pre-operative clinical setting. Using partially observed data from an existing cohort study (N=155), the authors asked whether patients with greater experience of childhood trauma in turn exhibit a larger mood boost and express greater subjective pleasure following opioid administration.

 

In contrast to previous findings, the results did not support the hypotheses that more experiences of childhood adversity would heighten ratings of drug liking and feeling good following opioid administration. Regression analyses instead revealed a statistically significant negative association between childhood adversity and post-opioid liking and no significant relationship with feeling good. The authors suggest that the discrepancy between the current and previous results may be due to stress related to the pre-surgical setting, the brief duration of drug exposure, and the relatively limited levels of high childhood adversity in the study sample. Nevertheless, these findings cast some doubt on the theory that adversity elevates risk of opioid addiction by altering sensitivity to subjectively pleasurable effects.

The world is seemingly awash with conspiracy theories – from well-trodden examples such as fake Moon landings, the 9/11 truth movement, and Holocaust denial, to relative newcomers including COVID as a bioweapon, QAnon, and the belief that the science of climate change has been invented or falsified. While there is a public perception that conspiracy theories are becoming more prevalent, recent evidence suggests that the rate of conspiracism is relatively stable over time (Uscinski et al., 2022). At any point in history, it seems that a certain proportion of people find themselves vulnerable to conspiracy beliefs, but what distinguishes those who do from those who don’t, and what are the causal factors?

 

In the current study, Liekefett et al. (2023) investigate the critical role of rumination – a perseverative and repetitive focus on negative content leading to emotional distress. In particular, the authors ask whether one component of rumination referred to as brooding (dwelling on one’s worries and distressing emotions) has a specific causal role in the formation of conspiracy beliefs. In a series of preliminary experiments, the authors first established a procedure for successfully inducing rumination, identifying various boundary conditions and requirements for a successful design. In the proposed study (of up to N=1,638), they will then ask whether the induction of brooding causes a significant increase in conspiracy beliefs. Manipulation checks will be included to confirm intervention fidelity (independently of this hypothesis), and exploratory analyses will test the effect of various moderators, as well as the causal role of a complementary manipulation of reflection – a component of rumination in which attention is focused on the issue at hand rather than one’s emotions.

The production effect is an intriguing memory phenomenon in which recall and recognition are improved when people read and study words aloud rather than silently. Although robust to a range of contexts, materials and manipulations, the underlying mechanisms that cause the production effect remain to be fully understood, largely due to the wide range of processes that are engaged during speaking compared to silent reading.

 

In the current study, Roembke and Brown (2024) ask whether semantic encoding – the encoding of new information based on its meaningful characteristics rather than sensory/perceptual characteristics – is a driving factor in production-enhanced memory. Across two carefully-controlled experiments in bilingual participants, the authors will test the hypothesis that the production effect should persist when items are matched in semantic but not other features at learning and recognition stages. If semantic encoding at least partially underpins the production effect, then they expect to observe it both when recognition items are presented as pictures or translations (their semantic recognition condition), and when recognition items match those at learning (their veridical recognition condition in which the same written words are presented at learning and recognition). Assuming also that the production effect does not rely exclusively on semantic encoding, the authors expect the production effect to be reduced in the semantic recognition conditions relative to veridical conditions in which words are matched on multiple linguistic features. 

 

The results of these experiments hold important implications for theoretical models of production-enhanced memory. If the authors find that the production effect persists when studied words can be recognised on their semantic features then this would suggest that production influences semantic encoding, which would in turn support theoretical models proposing that speaking engages modality-independent associations with semantic features. On the other hand, if no production effect is observed when participants are asked to recognise pictures or translations, this would raise the possibility that production may have little or no influence on semantic encoding, which would instead support alternative theories suggesting that speaking adds only modality-dependent features to memory traces.
