![]() Defacing biases in manual and automated quality assessments of structural MRI with MRIQCCéline Provins, Yasser Alemán-Gómez, Jonas Richiardi, Russell A. Poldrack, Patric Hagmann, Oscar Esteban https://osf.io/qcketThe impact of removing facial features on quality measures of structural MRI scansRecommended by D. Samuel SchwarzkopfData sharing is perhaps the most fundamental step for increasing the transparency and reproducibility of scientific research. However, the goals of open science must be tempered by ethical considerations, protecting the privacy and safety of research participants. Bridging this gap causes challenges for many fields, such as human neuroimaging. Brain images, as measured with magnetic resonance imaging (MRI), are unique to the participant and therefore contain identifying information by definition. One way to mitigate the risk to participants arising from public data sharing has been "defacing" the MRI scans, i.e., literally removing the part of the image that contains the face and surrounding tissue, while preserving the brain structure. This procedure however also removes information that is not (or at least minimally) identifiable. It also remains unclear whether defacing the images affects image quality and thus the information necessary for addressing many research questions.
The current study by Provins et al. (2023) seeks to address this question. Leveraging a publicly available "IXI dataset" comprising hundreds of T1-weighted structural MRI scans, they will assess the effect of defacing on manual and automatic estimates of image quality. Specifically, the researchers will compare image quality ratings by experts for a subset of 185 images. They hypothesise that images in which facial features have been removed are typically assigned higher quality ratings. Moreover, using a full data set of 580 images, which have been obtained across three scanning sites, they will also test the impact defacing MRI scans has on automated quality measures obtained with MRIQC software. The results of this study should have important implications for open science policy and for designing the optimal procedures for sharing structural MRI data in an ethical way. For example, if the authors' hypothesis is confirmed, studies relying on MRI quality measures might be better served by a custodianship model where identifiable data is shared under strict conditions, rather than relying on publishing defaced data. More generally, the outcome of this study may have significant legal implications in many jurisdictions.

![]() Does Brooding Meaningfully Increase the Likelihood of Believing in a Conspiracy? A Registered ReportLuisa Liekefett, Simone Sebben, Julia C. Becker https://osf.io/qf2av?view_only=5286ad5b89584a0ba7d1f238db9aa0b4Does brooding increase conspiracy beliefs?Recommended by Chris ChambersThe 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.

Sunk cost effects for time versus money: Replication and extensions Registered Report of Soman (2001)Nikolay PETROV, Yin Kan (Megan) CHAN, Cheuk Nam (Chris) LAU, Tin Ho (Donald) KWOK, Lok Ching (Estelle) CHOW, Wai Yan (Vivian) LO, Wenkai SONG, Gilad FELDMAN https://doi.org/10.17605/OSF.IO/PM264Mixed evidence for the hypothesis that sunk cost effects are weaker for time than moneyRecommended by Chris ChambersThe sunk cost fallacy is a cognitive bias in which people persist with a decision that is no longer optimal because of previous resources they have invested (now considered to be spent or “sunk”). Most of us will have heard sunk costs reflected in the saying “throwing good money after bad”, but sunk costs can, in theory, occur more broadly, whether for money, time or any other resource-limited investment. The sunk cost effect for money has been widely studied and appears robust; in contrast, the sunk cost effect for time is more uncertain, and is potentially moderated by the age of respondents (and likely resource availability), the fact that time is irreplaceable, and the tendency for people to account for time less easily than they do for money. In an impactful study, Soman (2001) found that the sunk cost effect for time was indeed weaker than for money, although this finding has not been widely replicated.
In the current study, Petrov et al. (2023) replicated three studies (1, 2 and 5) from Soman (2001), asking whether sunk costs are weaker for time than for money, and then testing whether the relative absence of a sunk time cost arises from the inability of participants to account for time or due to more rational beliefs in the evaluation of past time investments.
Results provided mixed support for the original findings. Consistent with Soman (2001), the sunk cost effect for money was reliably stronger than for time in Study 1; however, sunk costs for both money and time were comparable in Study 2 (and if anything, slightly stronger for time). The indirect replication of Study 5 from Soman (2001) found that the sunk cost effect for time was not significantly influenced by accounting for time, either using education or by highlighting opportunity costs. Robustness checks confirmed the main preregistered outcomes while also ruling out a range of potential alternative explanations. Overall, the results suggest that that sunk cost effects for time are more context-dependent and empirically volatile than sunk costs for money.

![]() 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 ShermanThe 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://doi.org/10.31234/osf.io/4br6aWhich 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 EspinosaTrust 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 ChambersSleep 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.

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.

STAGE 1
![]() Can playing Dungeons and Dragons be good for you? 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 KarhulahtiThe 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. Based on the comprehensive responses to the reviewers' feedback, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).
