STAGE 1
![]() A multilab investigation into the N2pc as an indicator of attentional selectivity: Direct replication of Eimer (1996)Martin Constant, Ananya Mandal, Dariusz Asanowicz, Motonori Yamaguchi, Helge Gillmeister, Dirk Kerzel, David Luque, Francesca Pesciarelli, Thorsten Fehr, Faisal Mushtaq, Yuri G. Pavlov, Heinrich R. Liesefeld https://psyarxiv.com/3472yIs the N2pc a correlate of attentional selection? An #EEGManyLabs multi-lab registered replication of Eimer (1996)Recommended by Maxine Sherman based on reviews by Reny Baykova and Clayton HickeyThe N2pc is a lateralised ERP component that is often interpreted as a marker of attentional allocation, so much so that it is frequently used a tool in the attention literature for inferring that a stimulus was attentionally processed. This interpretation of N2pc can be traced back to the seminal work of Eimer (1996), which has been conceptually replicated many times but has never been replicated directly.
This registered direct replication by Constant et al. (2023) forms part of a larger series of large-scale, multi-lab replications of highly influential EEG papers by the #EEGManyLabs project (Pavlov et al., 2021). Seven labs (with the potential for more to sign up later), will conduct high-powered replications of the critical Experiment 2 of Eimer (1996), where in the crucial conditions, participants discriminate a target letter (M vs W) or colour (blue vs green) in the presence of a distractor. Using four preprocessing pipelines, including the original, the authors will test whether the N2pc is observed over parieto-occipital electrodes contralateral to target presentation.
The Stage 1 manuscript was evaluated over one round of in-depth review and one additional round of minor corrections. Based on detailed responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).

Personal factors and group creativity characteristics: A correlational meta-analysisAdrien Alejandro Fillon; Fabien Girandola, Nathalie Bonnardel, Jared Kenworthy, Lionel Souchet https://psyarxiv.com/4br6a/Which personal factors are associated with group creativity?Recommended by Julia M. RohrerWhat determines whether groups of people can come up with ideas that are both original and useful? Since the 1960s, this question has been intensively studied with the help of more or less structured group creativity activities such as brainstorming or creative problem solving, with subsequent rating of the generated ideas. In this line of research, personal factors—such as personality traits, and other interindividual differences in emotion and cognition—have received substantial attention as potential correlates of creative outcomes of group activities. This has spawned a sprawling literature that, to date, has not yet been synthesized. Thus, empirical findings in this literature, which are also sometimes contradictory, have not yet been well-integrated. In the present study, Fillon et al. (2022) conducted the first meta-analysis of correlations between personal factors and group creativity outcomes. The authors searched and synthesized the existing published literature according to predetermined criteria to (1) assess the overall relationship between a broad list of personal factors and creativity outcomes in group settings and (2) explore potential moderators of these relationships. In total, 11 studies could be included in the meta-analysis. They provided weak support for a positive correlation between self-efficacy and the three investigated group creative outcomes, number of ideas, originality of ideas, and usefulness of ideas. With respect to moderators, many of the planned analyses could not be conducted due to the low number of studies. The only finding that arose was weak evidence for the idea that time constraint moderates associations: relationships between personal factors and group creativity outcomes were slightly stronger for tasks limited to 20 minutes rather than 10 minutes. Statistical power overall was low across studies. The authors conclude their meta-analysis with the observation that the available data on the topic are very limited. They suggest that to improve our knowledge of the topic, future studies should adhere to standardized creativity methods and protocols and implement expert ratings of creativity. They also call for increasing the availability of raw data in this field of study to improve the accumulation of knowledge about links between personal factors and the creative performance of groups. The Stage 2 manuscript was evaluated over one round of in-depth review provided by the recommender and Chris Chambers, as the original reviewers were no longer available. Based on additional changes to the manuscript, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

![]() Oxytocin, individual differences, and trust game behavior: a registered large-scale replicationCharlotte F. Kroll, Koen Schruers, Wolfgang Viechtbauer, Claudia Vingerhoets, Leonie Seidel, Arno Riedl, and Dennis Hernaus https://osf.io/6a9gs?view_only=a1fc6796bb92424aad28ff10c11fe595Does oxytocin enhance pro-social behaviors?Recommended by Romain Espinosa based on reviews by Thibaut Arpinon and 1 anonymous reviewerTrust 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.

![]() The relationship of memory consolidation with task incorporations into dreams – A registered reportSarah F. Schoch, Somayeh Ataei, Leila Salvesen, Michael Schredl, Jennifer Windt, Giulio Bernardi, Björn Rasch, Nikolai Axmacher, and Martin Dresler https://osf.io/h9t3vAre dreams important for memory consolidation?Recommended by Chris Chambers based on reviews by 1 anonymous reviewerSleep is known to be crucial for human memory, but what about dreams? Previous research has shown that the content of dreams can be manipulated by specific stimuli or tasks prior to sleep, but whether incorporating tasks into dreams influences memory consolidation is less clear. Some studies have shown an association between incorporating memory tasks into dreams and later memory performance, while others show either no effect or weaker effects. Potential reasons for this variation include the targeting of different stages of sleep – including rapid eye moment (REM) and non-REM stages (NREM) – small sample sizes, and the fact that many previous studies do not employ declarative memory tasks, which have been found to benefit more from sleep compared with tasks that target procedural memory.
In the current study. Schoch et al. (2023) ask whether dreams are an epiphenomenon of sleep-dependent memory processing or, instead, whether they play a key role in memory consolidation – and if so, whether that role differs for subjective experiences during NREM and REM sleep stages. Using a declarative memory task, a serial awakening paradigm (in which participants are woken and tested during NREM or REM stages), and targeted memory reactivation (TMR), the authors will test two main hypotheses: that incorporating picture categories of a declarative memory task leads to immediate (next morning) and sustained (4 days later) improvement in memory performance (especially for NREM dreams); and second, whether TMR influences the reported content of dreams. The authors also build in a range of control analyses to confirm that the task was incorporated successfully into dreams and that TMR benefited memory performance.

Gunschera and Christopher FergusonPeople are often drawn into intensive video game use in ways they or others may find troubling, harmless or even praiseworthy. Understanding these different experiences may help with integrating intensive technology use into everyday life in a healthy way.
In this programmatic submission, Karhulahti et al. (2023) will explore the gaming experiences of three groups of people (those who have sought treatment for gaming, esport players, and adolescents who play around two hours every day), using phenomenological and clinical interviews, and gaming diary logs every four months over three years. Around 200-300 participants will be recruited initially from Finland, Slovakia, and South Korea. In order to further increase cross-cultural range, the study will apply a new duplication method to collect similar data also in countries that have been studied little in the past. The aim will be to answer the questions of a) Is it possible to distinguish passionate from pathological gaming by the meanings and values that players attach to videogame play? and b) What are the design structures of videogames, which are played intensively and/or with gaming-related health problems? Ultimately, the study aims to synthesise all its data into a new taxonomic system, which can help better understand the differences and idiosyncrasies of gaming in lives across cultures.

A registered exploratory pilot program using offline Tabletop Role-Playing Games (TTRPGs) to mitigate social anxiety and reduce problematic involvement in multiplayer online videogamesJoël Billieux, Jonathan Bloch, Lucien Rochat, Loïs Fournier, Iliyana Georgieva, Charlotte Eben, Marc Malmdorf Andersen, Daniel Luke King, Olivier Simon, Yasser Khazaal, Andreas Lieberoth https://osf.io/hzyvaExpanding the Intervention Potential of Tabletop Role-Playing GamesRecommended by Veli-Matti Karhulahti based on reviews by Charlotte Pennington, Matúš Adamkovič and Matti VuorreThe 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. The Stage 1 manuscript was evaluated over two rounds by three experts with experimental specializations in psychopathology and gaming.

Stage 2 Registered Report: Stress regulation via being in nature and social support in adults, a meta-analysisAlessandro Sparacio, Ivan Ropovik, Gabriela M. Jiga-Boy, Adar Cem Lağap, Hans IJzerman https://doi.org/10.31234/osf.io/a4zmjDoes emotional support and being in nature influence stress?Recommended by Chris Chambers based on reviews by Felix Schönbrodt and Siu Kit YeungStress is a familiar presence in modern life and may be rising in severity (Almeida et al., 2020). As a key driver of many health problems, controlling stress and its impacts is a central goal in clinical and health psychology, yet the effectiveness of existing interventions to regulate stress remains unclear.
In the current study, Sparacio et al tackled this question from a meta-analytic perspective, focusing on a corpus of existing research that has addressed the efficacy of two specific stress regulation interventions: being in nature and emotional social support. As well as evaluating the evidential content of the relevant literatures, the authors also examined signs of publication bias and the moderating role of personality traits.
After correcting for publication bias, the results reveal evidence that being in nature is effective at reducing stress while emotional social support is not. The moderating role of personality for both interventions was inconclusive due to lack of evidence. In addition, the quality of the surveyed literature was found to be low overall, suffering from a high risk of bias and high rate of statistical reporting errors. The authors offer several recommendations to improve the rigour and quality of studies in this field, including open data, open materials, code review, preregistration and the use of Registered Reports.
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 awarded a positive recommendation.

Does childhood adversity alter opioid drug reward? A conceptual replication in outpatients before surgeryMolly Carlyle1*, Malin Kvande*, Isabell M. Meier, Martin Trøstheim, Kaja Buen, Eira Nordeng Jensen, Gernot Ernst, Siri Leknes, Marie Eikemo (*denotes equal contribution) https://osf.io/9kt3a?view_only=4238d2ee3d654c4f908a94efea82a027Is childhood adversity associated with a heightened response to opioids?Recommended by Chris Chambers based on reviews by Zoltan Dienes, Yuki Yamada and 1 anonymous reviewerA 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.
Following one round of in-depth review, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

STAGE 1
![]() The link between Empathy and Forgiveness: Replication and extensions of McCullough et al. (1997)'s Study 1Chan Chi Fung, Gilad Feldman https://osf.io/hxdmsIs empathy important for forgiveness?Recommended by Chris Chambers based on reviews by Wenrui Cao, James Bartlett and Saleh ShuqairForgiveness is a core feature of human psychology in which a person makes a deliberate decision to cease negative emotions or attitudes toward an offender who has done them harm. The concept of interpersonal forgiveness is deeply embedded across societies, but much remains to be understood about how it actually works. What are its key ingredients and why does it occur in the first place? Research in social psychology has demonstrated a range of personal and social benefits of forgiveness, giving rise to two dominant mechanistic accounts – one that positions empathy as the driving factor and another that centres motivated reasoning (Donovan & Priester, 2017).
In the current study, Chan and Feldman (2023) seek to replicate a formative study by McCullough et al (1997) that led to the so-called Empathy Model of forgiveness. According to this theory, forgiving is a motivational change facilitated (crucially) by empathy, promoting constructive over destructive behaviour toward the offender. Chan and Feldman will replicate Study 1 from McCullough et al., measuring the correlational relationship between apology, forgiving, and empathy for offenders, and exploring whether forgiving is associated with increased conciliation and decreased avoidance motivation. As well as closely replicating the original study, the authors will extend it to test the more severe hypothesis that empathy causally influences forgiveness. To achieve this, they will experimentally manipulate empathy by adding two groups to the design: one in which participants are asked to recall hurtful past experiences in which they were not empathetic to the offender, and another in which they were highly empathetic.
The Stage 1 manuscript was evaluated over two rounds of in-depth review. Based on detailed responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).
Level of bias control achieved: Level 6. No part of the data or evidence that will be used to answer the research question yet exists and no part will be generated until after IPA.
