Especially after the impactful experiments in modern comics (e.g. McCloud 1993), research interest in the medium increased with new practical developments (Kukkonen 2013). Some of these developments now manifest in educational settings where comics are used for various pedagogical purposes in diverse cultural contexts. To what degree comics are able to reach educational outcomes in comparison to other pedagogical tools remains largely unknown, however.
 
In the present registered report, Pagkratidou and colleagues (2024) respond to the research gap by investigating the effectiveness of educational comics materials. By means of systematic review and meta-analysis, the authors assess all empirical studies on educational comics to map out what their claimed benefits are, how the reported effectiveness differs between STEM and non-STEM groups, and what moderating effects complicate the phenomenon. With the help of large language models, all publication languages are included in analysis. 
 
The research plan was reviewed over three rounds by four reviewers with diverse sets of expertise ranging from education and meta-analytic methodology to comics culture and design. After comprehensive revisions by the authors, the recommender considered the plan to meet high Stage 1 criteria and provided in-principle acceptance.

Trust is a fundamental element for the well-functioning of our society. By achieving large levels of trust, societies can reduce monitoring costs (e.g., contract supervision, conflict resolution) and increase investments in more profitable but socially riskier projects. Trust serves as a way to foster cooperation among individuals and can benefit the entire social group.

 

As a result, numerous researchers have sought to explore the biological foundations of trust. In particular, several research teams have tried to explore the role of oxytocin in modulating prosocial behaviors. However, previous research findings obtained mixed findings, and several methodological issues, such as low statistical power, have hindered the development of a definite view on the matter.

 

In the current study, Kroll et al. (2023) seek to replicate the seminal study of Kosfeld et al. (2005). Kosfeld and co-authors originally found that the intranasal administration of oxytocin can significantly increase trust among individuals. However, recent replication evidence shows no general effect of oxytocin on pro-social behaviors or suggests that the effect might be heterogeneous among social groups (Declerck et al., 2020). The objective of the current study of Kroll et al. (2023) is twofold. First, the authors propose to replicate the original study of Kosfeld et al. (2005) and to investigate whether the lack of replication can be due to an overall effect that is smaller than the original findings suggest. Second, the authors propose to replicate recent but exploratory results on the heterogeneous effect of oxytocin on pro-social choices.

Does being good free people up to be bad? A large literature in social psychology suggests that it might, with evidence that moral licensing gives people a perception that actions deemed morally questionable, or socially undesirable, will be tolerated more readily if they have demonstrated a past history of praiseworthy, moral behaviour. In a formative study, Monin and Miller (2001) reported that having a track record of moral credentials as being nonprejudiced (e.g. non-sexist or non-racist) increased the willingness of participants to later express a prejudiced attitude. For example, in their Study 2 they found that participants who built up their moral credit by selecting a Black woman in a hypothetical recruitment task were then more willing to prefer a White man for a second job, compared to participants who did not have the opportunity to initially recommend a Black woman. These results have prompted a burgeoning literature on moral licensing, albeit one that is mixed and has been found to exhibit substantial publication bias.

 

In the current study, Xiao et al. (2024) undertook a large online replication of Study 2 in Monin and Miller (2001), asking whether previous moral behaviours that furnish participants with moral credentials make them more likely to then engage in morally questionable behaviours (N=932). The authors also extended earlier work by testing whether moral credentials license immoral behaviours more effectively in the same domain (e.g. within sex) than in a different domain (e.g. across sex and race), asking whether there is a negative relationship between expression of prejudice and trait reputational concern (fear of negative evaluation), and whether moral credentials attenuate any such observed relationship.

 

The results constitute a resounding non-replication, revealing no reliable evidence of a moral credential effect, no evidence that higher trait reputational concern predicts the expression of potentially problematic preferences, and no evidence that moral credentials moderate any such association. In discussing the implications of their findings, the authors call for further replication attempts and investigations of the effectiveness of experimental manipulations of moral licensing.

 

The Stage 2 manuscript was evaluated over one round of in-depth review. Based on detailed responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 2 criteria and therefore awarded a positive recommendation.

The popularity of gaming has spurred interest in understanding its impact on wellbeing. Significant research has investigated the impact of gaming from multiple angles. However, prior research has been limited by a lack of behavioural data that could be more reliable in examining the impact of gaming than self-reports of behavior. Similarly, previous research has called for examining the impact of gaming while taking genre differences into consideration.

 

In this programmatic submission (3 x Stage 2 outputs), Ballou et al. (2024) address these gaps by combining digital trace data of gamers across multiple gaming platforms (Nintendo Switch, Xbox (US only), Steam, and mobile systems (iOS and Android)) with psychological surveys measuring the gamers’ basic psychological needs, sleep quality, and subjective wellbeing over a three-month period. Participants will complete 30 daily surveys (US only) and six bi-weekly panel surveys.

 

The combination of behavioral trace data and psychological self-reports offers a rare and comprehensive look at how gaming influences different important aspects of wellbeing. This work is ambitious and addresses scientifically and socially important questions on the impact of gaming.

 

The manuscript underwent one round of in-depth review, where three reviewers with a combination of methodological and domain expertise gave generally positive feedback on the manuscript, providing directions to further strengthen the research. The authors – as judged by the recommender – thoroughly addressed the reviewer comments and have worked to further strengthen the rigour of the manuscript. A further revision round was issued by the recommender to address a minor issue with one hypothesis and other small linguistic edits.

 

Based on detailed responses to the recommender and reviewers' comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).

Mind-wandering broadly refers to the phenomenon by which a person's thoughts are directed towards internally generated states as opposed to being directed towards those that are task-relevant. It has been proposed that mind-wandering and cognitive control are supported by overlapping neural systems. While neuroimaging work has implicated prefrontal cortex in both mind-wandering and cognitive control, studies testing its causal role using transcranial direct current stimulation (tDCS) have been inconclusive.

 

Here, Rasmussen and colleagues (2025) put to a strict test the question of whether the effects of prefrontal cortex tDCS on mind-wandering are mediated by dopaminergic availablility, which is known to be important for cognitive control. Using noninvasive brain stimuluation (prefrontal cortex tDCS vs sham) and a pharmacological intervention (levodopa vs. placebo), they found that contrary to some previous work, stimulation of prefrontal cortex does not alter mind-wandering. By contrast, in the absence of stimulation, increasing dopamine availability via levodopa reduced the frequency of freely moving thought. Together, these results clarify the degree to which prefrontal cortex tDCS and dopamine play a causal role in mind-wandering
