STAGE 1
![]() See me, judge me, pay me: Gendered effort moralization in work and careLeopold H. O. Roth, Tassilo T. Tissot, Thea Fischer, S. Charlotte Masak https://osf.io/rz6yuA gender difference in effort moralization?Recommended by Adrien FillonEffort moralization is the well known idea that, unrelated to actual performance, people doing more effort are judged better, attributed more morality and seen as better collaborators than people doing less effort. However, the series of studies on this topic mostly used vignettes with a man or a neutral protagonist. The current study by Roth et al. (2025) proposes to tackle the gender problem by testing the difference in attribution morality between a man and a woman protagonist, and two contexts: a “care” and a “work” context, mirroring the stereotypes associated with men and women.
The authors included two different and adequate power analyses, various interpretation of the possible effects, and filtering to ensure a high quality of data collection. They also provide a supplementary repository including the qualtrics survey, R script, and simulated data.
The Stage 1 manuscript was evaluated over two rounds of in-depth review. Based on detailed responses to the reviewers’ and the recommender’s comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance.

Unveiling the Positivity Bias on Social Media: A Registered Experimental Study On Facebook, Instagram, And XAlexandra Masciantonio, Neele Heiser, Anthony Cherbonnier https://osf.io/s93yuSocial media positivity bias, or just positivity bias?Recommended by Veli-Matti KarhulahtiBoth research and public debates around social media use tend to involve a premise of positivity bias, which refers to presenting one’s life in an overly positive light by various different means. This premise contributes to multiple potentially important follow-up hypotheses, such as the fear of missing out and low self-image effects, due to repeated consumption of positive social media content (e.g., Bayer et al. 2020, for a review). The positivity bias of social media use, itself, has received limited research attention.
In the present study, Masciantonio and colleagues (2025) tested positivity bias in the context of three social media platforms: Facebook, Instagram, and X. The experiment involved recruiting participants (n=312) into platform-specific user groups and crafting posts to be shared with friends as well as respective social media audiences. For social media positivity bias to differ from everyday positivity bias, posts in the former should introduce more positive valence in comparison to offline sharing—and if the platforms differ in their encouragement of positivity bias, they should introduce significant between-platform differences in valence. Based on how the participants reported events, the study found no significant differences between everyday and social media positivity bias, but messages posted on Twitter/X had a more negative valence than posts in other social media platforms. The results would be consistent with the implication that people's positive actions in social media simply follow the natural human tendency to present oneself positively to others—a hypothesis that should be investigated in follow-up work. More research attention should also be given to specific design features, which may contribute to platform-specific differences in user habits, as suggested by the distinct valence rate found in relation to Twitter/X. The Stage 2 manuscript was evaluated by three experts (areas: experimental methods, social media, statistics) via in-depth peer review across two rounds, with one reviewer returning to validate analysis code and methdological accuracy on a final round. Based on the authors’ careful responses and revisions, the revised manuscript was judged to meet the Stage 2 criteria and was awarded a positive recommendation.

Michotte's research on perceptual impressions of causality: a registered replication studyPeter A. White https://osf.io/jdac7Michotte’s classic studies on the perception of causality: Replications, extensions and a sound base for further researchRecommended by Moin SyedMaking causal judgements are part of everyday life, whether seeking to understand the action of complex humans or the relations between inanimate objects in our environments. Albert Michotte’s (1963) classic book, The perception of causality, contained an extensive report of experiments demonstrating not only that observers perceive causality of inanimate shapes, but do so in manifold ways, creating different “causal impressions.” This work has been highly influential across psychology and neuroscience.
In the current study, White (2025) conducted 14 experiments aimed at replicating and extending Michotte’s work. Despite the fact that this research is foundational to current work on perception and understanding of causal relations, it has never been subject to rigorous replication. Moreover, like many research studies from that era, Michotte was sparse on details about methodology and did not rely on statistical analysis. White carried out an ambitious set of 14 experiments and 18 hypotheses that directly replicated and, in some cases, extended Michotte’s experiments. The results of the experiments were mixed, with the hypotheses evenly divided among being supported, partially supported, and not supported. The current effort by White not only brings rigorous contemporary data to classic studies of perceptual impressions of causality, but the results point to important new directions for future study on the topic. In particular, the findings suggest a need to broaden our investigations of causal explanations of movement beyond launching (i.e., contact of one object leading to motion of another) to also consider entraining (i.e., joint movement following contact) and pulling. The collected studies provide fertile ground for further testing a variety of mechanisms that explain different perceptual impressions of causality.
The Stage 2 manuscript was evaluated over three rounds of in-depth review, the first two rounds consisting of detailed comments from two reviewers and the third round consisting of a close read by the recommender. Based on detailed responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

Do Ecological Valid Stop Signals Aid Detour Performance? A Comparison of Four Bird SpeciesAnneleen Dewulf, Clara Garcia-Co, Wendt Müller, Joah R. Madden, An Martel, Luc Lens, Frederick Verbruggen https://osf.io/j2k9hWhat is the role of sensory perception in cognitive task performance? An improved replication of detour performance in four different bird speciesRecommended by Dieter LukasThe detour task, where an individual has to go around a see-through barrier in order to reach a goal, is one of the oldest paradigms used in animal cognition research (Kabadayi et al. 2018). While these previous tests have documented variation in the ability of animals to inhibit going straight for the visible reward, the cognitive underpinnings of this behaviour are as yet not fully understood. In the current study, Dewulf et al. (2025) assessed one of the specific cognitive processes that might be involved in this behaviour, the ability to identify the transparent object as a barrier. Through experimental procedures relying on large samples of individuals from four bird species, they compared the role of signal detection in inhibitory response performance in a detour task. The authors found that, unlike suggested in previous work with these four species (Regolin et al. 1994, Zucca et al. 2005), changing the markings on the barriers to potentially better match those experienced by individuals in their natural environments did not improve their performance. Nevertheless, the detailed further explorations suggest that in order to understand variation in how quickly individuals and species solve the detour task, it is important to consider that different cognitive processes are involved. Their work therefore provides a basis to better understand and further investigate why species might differ in their performance in the detour task.

Action interpretation determines the effects of go/no-go and approach/avoidance actions on food choiceZhang Chen, Pieter Van Dessel, Jordi Serverius, Daxun Zhu, Bernd Figner https://osf.io/preprints/psyarxiv/6xhw4_v2Does interpretation of actions as either avoid or inhibit influence choice behaviour for candy?Recommended by Andrew Jones based on reviews by Alexander MacLellan and Katrijn HoubenExperimental research demonstrates that executing or inhibiting motor responses (or approaching / avoiding) towards a stimulus can alter the valuation of the stimulus (Yang et al., 2022). There are competing theories as to the proposed mechanisms of value change, such as increased response conflict or prediction errors (Houben & Aulbach, 2023). However, research has mostly examined response execution/inhibition and approach/avoidance in isolation and the few studies that have examined these together have focused on stimulus evaluation as an outcome.
In the current study Chen et al. (2025) set out to examine how action interpretations (e.g. go vs approach) can impact individuals food-choices. This is important for cognitive bias modification approaches which aim to manipulate these actions to promote behaviour change (Iannazzo et al., 2024; Veling et al., 2021), but also theoretical accounts which suggest certain motor-responses acquire valence. Here there are two groups randomised to receive instructions to either go/no-go or approach/avoid images of candy in novel training task (Chen et al., 2019).
The results of the experiment suggested that despite both groups making the same responses (pressing a space bar vs not), the framing of the response as go vs approach and no-go vs avoidance influenced subsequent food-choice (i.e. responses framed as approach increased the probability of choosing approach items over avoidance items, but not go items over no-go items). As the authors state, these findings cast doubt on theoretical models which suggest there are ‘hardwired’ links between specific go/approach responses and appetitive systems or specific no-go/avoidance responses and aversive systems. They also suggest these responses aren’t valenced, but acquire valence through interpretation of the action. These findings can also inform future studies into cognitive bias modification. The Stage 2 manuscript was evaluated over two rounds of in-depth review by two reviewers with expertise in the relevant area, who also assessed the Stage 1 manuscript. Based on the authors’ careful responses and revisions, the revised manuscript was judged to meet the Stage 2 criteria and was awarded a positive recommendation.

Loenneker, Inga Liepelt-Scarfone, Klaus Willmes, Hans-Christoph Nuerk, & Christina Artemenko https://osf.io/cdxfm/?view_only=9ddf45dcfdd846f3998cfb0d842dcf16Getting the numbers right in Parkinson's disease?Recommended by Zoltan DienesEveryday life, including for patients taking different types of medicine, involves dealing with numbers. Even though Parkinson's disease may ordinarily be thought of as primarily being a motor disorder, there is evidence that numerical abilities decline as Parkinson's disease progresses. Further, the brain areas involved in arithmetic operations overlap with the areas that degenerate in Parkinson's disease. In this Stage 1 Registered Report, Loenneker et al. (2022) will test healthy controls, Parkinson disease patients with normal cognition, and Parkinson disease patients with mild cognitive impairment on general working memory tasks as well as arithmetic performance on the four basic operations (addition, subtraction, multiplication, division). The study aims to test whether or not there is a deficit in each operation, and the relation of any deficits to general working memory capacity. The Stage 1 manuscript was evaluated over four rounds of review (including two rounds of in-depth specialist review). Based on comprehensive responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).

Life Thinning and Gaming Disorder: A Longitudinal Qualitative Registered ReportVeli-Matti Karhulahti, Miia Siutila, Jukka Vahlo, Raine Koskimaa https://doi.org/10.31234/osf.io/rfbcuHow do intensive gaming experiences evolve over time in clinical and non-clinical contexts?Recommended by Chris ChambersOver the last 5 years the inclusion of “gaming disorder” in the ICD-11 been controversial (Van Rooij et al, 2018), mirroring wider public debate about the effects of gaming on mental health. One of the major gaps in understanding the validity of gaming disorder as an identifiable mental illness is the absence of qualitative studies comparing the lived experience of gamers who seek treatment with esports players who do not report health problems.
Here, Karhulahti et al. (2023) tackle this question in the second of two Stage 2 Registered Reports associated with their previous programmatic Stage 1 submission. Using interpretative phenomenological analysis, the authors undertook in-depth interviews over a 1-year period with treatment-seeking participants (N=5) and esports-playing participants (N=4) who did not experience gaming-related health problems. The authors sought to answer the folllwing primary question: How do the experiences and meanings of playing videogames—shaped by the individuals’ diverse sociocultural contexts—evolve in those with related health problems (as defined by treatment-seeking) and those who play esports games several hours per day while self-reporting no related health problems?
Both groups exhibited intense relationships with gaming that were cyclical over time across various dimensions, with fluctuations occurring in response to changes in health, occupation, and social networks. The observed variation over time was substantial, with individuals attaching and detaching from games involving hundreds or thousands of hours. The authors report treatment-seeking being followed by a search of new gaming and life meanings, while intensive gaming without related problems continued as an integrated part of the self, with resilience adapting and evolving in the face of unexpected life events. Taking into account their findings, the authors propose life thinning and resilience integration processes to help describe and explain how some individuals end up seeking treatment for their gaming, while for others gaming supports them and becomes integrated into their identity.
Following one round of in-depth review and revision, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

STAGE 1
Alexis J. Breen & Dominik Deffner https://github.com/alexisbreen/Sex-differences-in-grackles-learningRecommended by Benoit PujolThis submission has been withdrawn (see notice below)Sex-biased dispersal is widely acknowledged to influence range expansion and the geographic limits of species (Trochet et al. 2016). Evidence is accruing that suggests an impact of the learning ability of species on their capacity to colonise new habitats because the ability to learn provides an advantage when confronted to novel challenges (Lee and Thornton 2021). Whether these two mechanisms interact to shape range expansion remains however unknown. One could expect this interaction because both dispersal and the ability to learn are linked to related behaviours (e.g., exploration, Lee and Thornton 2021). In their study entitled “Investigating sex differences in learning in a range-expanding bird”, Alexis J. Breen and Dominik Deffner (Breen and Deffner 2022) propose to test this hypothesis in range-expanding great-tailed grackles (Quiscalus mexicanus) by exploring the individual variation of several behavioural traits (e.g., exploration, neophobia, problem solving, Logan 2016) linked to their learning ability. They will use a colour-reward reinforcement experimental approach to compare the learning performance between male and female great-tailed grackles in three study sites and evaluate whether sex-biased learning ability interacts with sex-biased dispersal. Data will be analysed by a Bayesian reinforcement learning model (Deffner et al. 2020), which was validated. This Stage 1 registered report was evaluated over one round of in-depth review by Jean-François Gerard, Rachel Harrison and one anonymous reviewer, and another round of review by Jean-François Gerard and Rachel Harrison.

Phenomenological Strands for Gaming Disorder and Esports Play: A Qualitative Registered ReportVeli-Matti Karhulahti, Miia Siutila, Jukka Vahlo, Raine Koskimaa https://doi.org/10.31234/osf.io/q53jzThe lived experience of gamers: a comparative qualitative investigation of treatment-seekers and esports playersRecommended by Chris ChambersSince 2018, the inclusion of “gaming disorder” in the ICD-11 has been met with a mixture of interest, confusion and controversy (Van Rooij et al, 2018), mirroring broader debates about the effects of gaming on mental health. One of the major gaps in understanding the validity of gaming disorder as an identifiable mental illness is the absence of qualitative studies comparing the lived experience of gamers who seek treatment with esports players who do not report health problems.
Here, Karhulahti et al. (2022) tackle this question in the first of two Stage 2 Registered Reports associated with their previous programmatic Stage 1 submission. Using interpretative phenomenological analysis in gamers and medical experts, they find that treatment-seekers and esports players differ in how gaming is associated with the sense of self, either interfering with the self for treatment-seekers or successfully integrating into the self for esports players. These findings help to identify the key characteristics of problematic and non-problematic gaming and call for more intensive and wide-reaching qualitative research in this area.

STAGE 1
![]() Dose-response of tDCS effects on motor learning and cortical excitability: a preregistered studyGavin Hsu, Dylan J. Edwards, Leonardo G. Cohen, Lucas C. Parra https://osf.io/k6abpHow stimulation intensity affects motor learningRecommended by Christina ArtemenkoIn neurostimulation research, the parameters of a stimulation protocol crucially impact on the effects of the stimulation. Transcranial direct current stimulation (tDCS) is a neurostimulation technique that typically uses current intensities about 1-2 mA in human research to modulate motor and cognitive behavior. The current sham-controlled study by Hsu et al. (2024) applies current intensities not only of 2 mA but also of 4 mA and 6 mA and thus extends our understanding of stimulation parameters while ethical standards are preserved.
The influence of tDCS over the primary motor cortex will be evaluated for neural plasticity during motor learning. Stimulation effects will be tested not only behaviorally but also physiologically by motor evoked potentials elicited by transcranial magnetic stimulation (TMS). The presented pilot data are promising and underline the feasibility of the proposed research design. The study will contribute to tDCS research by uncovering reasons for controversial findings and thus increase reproducibility.
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).
