STAGE 1
A systematic review of social connection inventoriesImproving the measurement of social connectionRecommended by Dorothy Bishop based on reviews by Jacek Buczny, Richard James and Alexander Wilson
This is an ambitious systematic review that uses a combination of quantitative and qualitative methods to make the measurement of the construct of social connection more rigorous. Social connection is a heterogeneous construct that includes aspects of structure, function and quality. Here, Paris et al. (2024) will use predefined methods to create a database of social connection measures, and will assess heterogeneity of items using human coders and ChatGPT. This database will form the basis of a second systematic review which will look at evidence for validity and measurement properties. This study will also look at the population groups and country of origin for which different measures were designed, making it possible to see how far culturally specific issues affect the content of measures in this domain.
The questions asked by this study are exploratory and descriptive and so the importance of pre-registration is in achieving clear criteria for how each question is addressed, rather than evidential criteria for hypothesis-testing.
The authors responded comprehensively to three reviewer reports. This study will provide a wealth of useful information for those studying social connection, and should serve to make the literature in this field more psychometrically robust and less fragmented.

STAGE 1
The Role of Offender Identifiability in Second- and Third-Party PunishmentPunishing OffendersRecommended by Clare Conry-Murray based on reviews by Gilad Feldman and Rajarshi Majumder
When people are less-well-known to us, it can impact how we treat them. People outside our communities may feel more anonymous or de-personalized to us, and this could impact the empathy we feel for them. Indeed, past research shows that people seem to care more for those who are who are identified to us, especially when they are victims of a crime (Small & Loewenstein, 2003). In addition, past research also shows that anonymizing victims can influence criminal behavior (Walters, 2022). Thus, social cognitive factors related to anonymity appear to affect both positive feelings (engaging in empathy) and negative activities (criminal activity) related to victims. It seems likely that anonymity can also affect how people judge criminals themselves.
This paper by Blanke and Twardawski (2024) examines how even minor identifying features can make individuals react differently to a perpetrator of a crime. A picture or name (information that may appear in the press) may impact how people perceive criminals in terms of punishment, empathy, outrage, and blame.
How people respond to anonymous or identified criminals may depend on whether the impact of the crime on the victim is made salient. Similar to the Black Sheep Effect (Marques & Paez,1994), the current paper expects that people who identify with victims are expected to punish a perpetrator more when the perpetrator’s name and image are known. This is similar to the case with an ingroup member in The Black Sheep Effect, where ingroup members are punished more for transgressions than outgroup members. For people who view the situation as a third party (and are thus less connected to the victim), an identified perpetrator is expected to lead to less punishment (and also less outrage and blame, and more empathy).
The current study focuses on pickpocketing since it is a crime that can be committed without identifying oneself to the victim. Future research should examine how the type of event impacts judgments, especially given the stigma of being a victim of some crimes. Littering and other minor violations may be seen as understandable when you see someone as a person, rather than a anonymous, impersonal criminal. On the other hand, there can be stigma to being a victim in some cases, such as the case of sexual harassment, where, research shows, perpetrators are judged more positively if they are identified, and victims, especially women, are judged more negatively if they are identified (Barak-Corren & Lewinsohn-Zamir, 2019).
People around the world engage in moral and legal transgressions, and if our judgments of them are influenced by minor features such as a photo or name, we should take action to treat people more fairly. This research will help to determine if people are influenced by these factors.
The Stage 1 manuscript underwent one round of thorough review. After considering the detailed responses to the reviewers' comments, the recommender determined that the manuscript met the Stage 1 criteria and granted in-principle acceptance (IPA).

STAGE 1
Recommended by Benoit Pujol based on reviews by Jean-François Gerard, Rachel Harrison and 1 anonymous reviewer
This 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.

Changes in memory function in adults following SARS-CoV-2 infection: findings from the Covid and Cognition online study.Evidence for General Long-Term Memory Impairment Following SARS-CoV-2 InfectionRecommended by Vishnu Sreekumar based on reviews by Phivos Phylactou, Mitul Mehta and 1 anonymous reviewer
COVID-19 has been associated with cognitive impairments, particularly in memory performance (Guo et al., 2022). Given that associative memory typically declines earlier than item memory in conditions such as mild cognitive impairment (Chen & Chang, 2016), it remains an open question whether COVID-19 differentially affects item and associative memory. Furthermore, it is unclear whether such effects are specific to verbal or non-verbal material. To investigate these questions, Weinerova et al. (2024) recruited participants via long-COVID Facebook groups and clinical settings. They reported a significant detrimental effect of COVID-19 status on long-term memory performance across tasks. However, they did not find evidence for their preregistered hypothesis of an interaction between COVID-19 status and either memory type (item vs. associative) or stimulus type (verbal vs. non-verbal).
In the Stage 1 report, the authors preregistered a Bayes Factor threshold of 6 as the criterion for supporting the alternative hypothesis. All planned analyses were preregistered, incorporating both frequentist methods (to replicate Guo et al., 2022) and Bayesian ANCOVA (to test the preregistered hypotheses). As data collection had been completed at the time of Stage 1 submission, we assigned a Level 3 bias control to the Stage 1 report.
In the Stage 2 report, the authors confirmed a general negative impact of COVID-19 on long-term memory accuracy. Using frequentist ANCOVA, they successfully replicated Guo et al. (2022)’s findings of reduced accuracy in verbal item and non-verbal associative memory among individuals with prior COVID-19 infection. However, they did not replicate the previously observed effect on reaction times. The Bayesian ANCOVA analyses did not reach the preregistered evidential threshold (BF > 6). Verbal associative memory, which was not part of the original replication attempt, also showed reduced accuracy in individuals with prior infection. In contrast, performance on non-verbal item memory tasks showed a ceiling effect, possibly due to methodological differences from Guo et al. (2022). Across all four memory tasks, the authors found robust evidence for decreased accuracy associated with COVID-19 status but no effect on reaction times.
Contrary to their hypotheses, models that included interactions between COVID-19 status and either memory type or stimulus type were less likely than the null model, suggesting a general, rather than specific, detrimental effect of COVID-19 on long-term memory.
Analyses of vaccination status yielded inconclusive results, likely due to limited sample size and uncertainty in participants' self-reports of vaccination timing relative to infection. The question of whether vaccination has protective effects on cognition remains unresolved and merits further investigation. The authors also reported tentative exploratory findings, such as a potential association between longer time since infection and slower reaction times in verbal item memory tasks. These observations require confirmation in future studies.
Overall, the study makes a valuable contribution by replicating prior findings and extending them to suggest a broad impairment of long-term memory associated with COVID-19.
The Stage 2 report was reviewed by the same three reviewers who had evaluated the Stage 1 submission. All reviewers agreed that the authors had addressed prior comments and had adhered to the preregistered methodology and analysis plan. As in the Stage 1 evaluation, we note the potential for selection bias introduced by recruiting participants via long-COVID Facebook groups. Individuals with post-infection cognitive complaints may have been more likely to volunteer, limiting generalizability to the broader SARS-CoV-2-infected population. This and other limitations are clearly acknowledged in the Discussion section of the Stage 2 manuscript. The recommender judged that the manuscript met all Stage 2 criteria for recommendation.

Does Truth Pay? Investigating the Effectiveness of the Bayesian Truth Serum with an Interim Payment: A Registered ReportDo interim payments promote honesty in self-report? A test of the Bayesian Truth SerumRecommended by Romain Espinosa and Chris Chambers based on reviews by Philipp Schoenegger, Sarahanne Miranda Field and Martin Schnuerch
Surveys that measure self-report are a workhorse in psychology and the social sciences, providing a vital window into beliefs, attitudes and emotions, both at the level of groups and individuals. The validity of self-report data, however, is an enduring methodological concern, with self-reports vulnerable to a range of response biases, including (among others) the risk of social desirability bias in which, rather than responding honestly, participants answer questions in a way that they believe will be viewed favourably by others. One proposed solution to socially desirable responding is the so-called Bayesian Truth Serum (BTS), which aims to incentivise truthfulness by taking into account the relationship between an individual’s response and their belief about the dominant (or most likely) response given by other people, and then assigning a high truthfulness score to answers that are surprisingly common.
Although valid in theory (under a variety of assumptions), questions remain regarding the empirical utility of the BTS. One area of concern is participants’ uncertainty regarding incentives for truth-telling – if participants don’t understand the extent to which telling the truth is in their own interests (or they don’t believe that it matters) then the validity of the BTS is undermined. In the current study, Neville and Williams (2024) aim to test the role of clarifying incentives, particularly for addressing social desirability bias when answering sensitive questions. The authors will administer an experimental survey design including sensitive questions, curated from validated scales, that are relevant to current social attitudes and sensitivities (e.g. “Men are not particularly discriminated against”, “Younger people are usually more productive than older people at their jobs”). Three groups of participants will complete the survey under different incentive conditions: the BTS delivered alone in standard format, the BTS with an interim bonus payment that is awarded to participants (based on their BTS score) half-way through the survey to increase certainty in incentives, and a Regular Incentive control group in which participants receive payment without additional incentives.
The authors will then address two questions: whether the BTS overall effectively incentivises honesty (the contrast of BTS alone + BTS with interim payment vs the Regular Incentive group), and whether interim payments, specifically, further boost assumed honesty (the contrast of BTS alone vs BTS with interim payment). Regardless of how the results turn out, the study promises to shed light on the effectiveness of the BTS and its dependence on the visibility of incentives, with implications for survey design in psychology and beyond.

Shape of SNARC: How task-dependent are Spatial-Numerical Associations? A highly powered online experimentShedding light on task influence in the SNARC effectRecommended by Mario Dalmaso based on reviews by Michele Vicovaro, Christian Seegelke, Peter Wühr and 1 anonymous reviewer
The Spatial-Numerical Association of Response Codes (SNARC) effect (Dehaene et al., 1993) is a key phenomenon in numerical cognition. It describes the tendency for individuals to respond faster to smaller numbers with a left-side key and to larger numbers with a right-side key, suggesting a mental mapping of numerical magnitudes onto space. While this effect has been widely replicated, its precise nature remains debated, particularly regarding its task dependency.
In this Stage 1 Registered Report, Roth et al. (2025) present a highly powered study that systematically investigates whether the SNARC effect differs in two widely used numerical cognition tasks: magnitude classification (MC) and parity judgment (PJ). In the MC task, participants determine whether a presented number is smaller or larger than a reference value (typically 5). This task explicitly requires magnitude processing, making numerical magnitude directly relevant to the response. In contrast, the PJ task requires participants to judge whether a number is odd or even, a decision that does not explicitly involve numerical magnitude.
The authors address a fundamental theoretical question in numerical cognition: while the SNARC effect in PJ is often considered continuous, does it follow a categorical pattern in MC? To investigate this, the study directly compares continuous and categorical representations of the SNARC effect across these two tasks, using Bayesian statistical approaches to determine the best-fitting model. By systematically analysing the SNARC effect in these widely used paradigms, this work aims to refine our understanding of how numerical magnitudes are mapped onto space and whether this mapping depends on task demands. The findings of this study will provide crucial insights into the cognitive mechanisms underlying numerical-spatial associations, highlighting the extent to which task structure shapes the emergence of the SNARC effect.
Three expert reviewers provided valuable feedback across multiple rounds of review. Based on detailed responses to the reviewers’ and recommender’s comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance.

Reconstructing Gaming Disorder: A Taxonomy by Registered ReportHow can the experiences of those who engage in video games in healthy and unhealthy ways be systematically organised?Recommended by Zoltan Dienes based on reviews by Michelle Carras, Lukas J. Gunschera and Christopher Ferguson
People 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.

Noninvasive Neuromodulation of Visual Perception and Neural Connectivity in Body Dysmorphic Disorder: A Registered ReportUnderstanding the combined effects of brain stimulation and visual attention modification in body dysmorphic disorderRecommended by Anna Elisabeth Fürtjes based on reviews by Samuel Westwood and 1 anonymous reviewer
This study by Diaz-Fong et al. (2025) plans to investigate body dysmorphic disorder (BDD), an understudied psychiatric condition marked by distortions in the perception of a patients’ physical appearance. The authors build on evidence that perceptual symptoms in BDD are underpinned by attentional biases, which may relate to abnormal visual processing and neural connectivity in the dorsal visual stream (DVS; reduced activation) and the ventral visual stream (VVS; increased activation). Prior evidence suggests that activation in the DVS and the VVS may be modifiable by both non-invasive neuromodulation (including transcranial magnetic stimulation), as well as behavioural interventions such as the Visual Modification (ModV) paradigm, which has been suggested to reduce patients’ foveal attention to perceived bodily defects. The ModV paradigm has been specifically linked with altered VVS and DVS activation and connectivity.
Here the authors will test in a within-subject crossover design (N = 40) whether neural connectivity and visual perceptual biases in BDD and subclinical BDD can be modified by combining the effects of altered visual attention in the ModV paradigm with repetitive transcranial magnetic stimulation (continuous and intermittent theta burst stimulation; cTBS and iTBS). By combining a behavioural and an exogenous intervention, the authors predict an increase in the magnitude of clinically meaningful improvements in attentional biases in BDD, with iTBS expected to enhance, and cTBS expected to inhibit the effects of visual attention modification through ModV on neural connectivity (measured using fMRI) and visual processing. More specifically, the effect of TBS is hypothesised to be stronger after patients perform ModV.
The Stage 1 manuscript was evaluated by two experts who performed in-depth peer review across multiple rounds of revisions. The authors were responsive in editing their manuscript based on the reviewers’ comments and dedicated much effort to increasing the clarity and interpretability of their power analyses. The revised manuscript was judged to meet the Stage 1 criteria and was awarded in-principle acceptance (IPA).

STAGE 1
Does synchronised singing enhance social bonding more than speaking does? A global experimental Stage 1 Registered ReportDo humans bond more when singing together or speaking together? A global investigationRecommended by Katherine Moore based on reviews by Melissa Brandon, Erin Hannon, Manuela Maria Marin and Anja Göritz
Music is a universal across human cultures, but there is debate as to why and how it evolved. For example, Pinker has famously argued that music is “auditory cheesecake,” with no biological value (Pinker, 1997). Most scholars on the evolution of music make comparisons with language, another human universal that is unique to our species (Friederici, 2017). A current leading hypothesis in the evolution of music is the social bonding hypothesis, which suggests that music plays a special role in social bonding beyond the role that language plays (Savage et al., 2021).
Previous studies have provided evidence that synchronized music-making can promote social bonding (e.g. Stupacher et al., 2021). However, it is unclear whether synchronous singing provides any advantage in social bonding as compared to merely speaking. Previous work on this topic has at times lacked sufficient controls and has potentially been subject to publication bias—it could be that only the studies with statistically significant findings are in the published literature, when in fact additional experiments may have been run with unpublished null results. Also critically, prior studies have been subject to sampling bias—the vast majority are limited to a small set of cultures and musical styles, focusing primarily on English-speaking cultures and western music (Henrich & Heine, 2010). If music has evolved as a mechanism for social bonding, then it is especially critical to demonstrate its effects on social bonding across a wide range of cultures.
In a remarkable global collaboration including 88 collaborators from six continents, Savage et al. (2025) plan to collect data on synchronized singing and speech from 1710 participants across 57 research sites. Participants will be assigned to participate in (1) a synchronized singing activity, (2) a synchronized speech activity, or (3) a natural, prompted conversation.
At each research site, participants will gather in groups of 5-10 and will be randomly assigned to one of the three conditions (for the research site to be valid, it must recruit one group of participants into each condition). The experiment will start with pre-test measures of social bonding and other variables. Next, the intervention will commence. In the singing condition, participants will synchronously sing a song that is highly familiar in that culture. In the lyrics recitation condition, participants will synchronously speak printed lyrics to the songs from the singing condition (twice through, to account for speed differences in song and speech). In the conversation condition, participants will have a natural conversation in response to an ice-breaker question. Finally, each group will engage in post-test measures of social bonding as well as debriefing.
The social bonding hypothesis predicts that participants in the synchronized singing task will experience more social bonding (as measured by a pre- and post-test differences) than will participants who engage in sequential conversation or synchronous lyrics recitation in the absence of musical pitch or rhythm. The unprecedented scale of this global, cross-cultural investigation will make a great impact on the field and on our understanding of the relationship among speech, song, and social connection, regardless of the outcome.
Four expert reviewers provided valuable feedback through two rounds of 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.

STAGE 1
A climate action intervention to boost individual and collective climate mitigation behaviors in young adultsPutting climate action intervention to the test: Part 1Recommended by Chris Chambers based on reviews by Helen Landmann, Jana Kesenheimer and 1 anonymous reviewer
It is increasingly recognised that resolving the climate crisis will require not only the reform of law and government policy but collective grassroots action to change individual behaviour and put public pressure on political leaders, companies and institutions to cut emissions. The capacity, however, for individual citizens to take such steps is limited by lack of knowledge/awareness of means and opportunities as well as psychological barriers that can make such actions seem impossible, fruitless or against the person's immediate self-interest. Interventions designed to overcome these obstacles and promote individual behaviour change have met with only limited success, with many based on weak psychological evidence and the outcome measures used to evaluate their success prone to error and bias.
In the current submission, Castiglione et al. (2024) propose a series of five studies to test, evaluate, and optimise a longitudinal intervention for engaging young adults (aged 18-35) in individual and collective climate action. Building on existing theory and evidence, the authors have designed an intensive 6-week educational intervention that draws on 12 psychological factors linked to pro-environmental behaviour, including emotional engagement, self-efficacy, collective efficacy, theory of change, cognitive alternatives, perceived behavioral control, implementation intentions, social norms, self-identity, collective identity, appraisal, and faith in institutions. Through the use of ecological momentary assessment (EMA), they plan to measure these targeted psychological correlates as well as individual and collective climate engagement of participants before and after the intervention (and in active groups vs. controls), and then again after a further three months.
The current submission is novel in being the first at PCI RR (and possibly the first RR anywhere) to propose an incremental programmatic workflow that combines two innovations: a single Stage 1 protocol leading to multiple Stage 2 outputs (under the PCI RR programmatic track) and a prespecification in which the design of the intervention in later studies is (for now) determined only broadly, with specific parameters to be shaped by the results of the first set of studies (under the PCI RR incremental registrations policy). This particular Stage 1 manuscript specifies the design of study 1 in two samples (high-school and university students in Italy; producing one Stage 2 output for each sample) and the general design of subsequent studies. The details of this later research in study 2 (in the same two populations) and study 3 (university students in the Netherlands) will be developed sequentially based on the results of the previous Stage 2 outputs and the state of the literature at that time.
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). Following the completion of study 1, the authors will submit an updated Stage 1 manuscript for re-evaluation that updates the plans for later studies accordingly, hence the current recommendation is labelled "Part 1".
