STAGE 1
Development and evaluation of a revised 20-item short version of the UPPS-P Impulsive Behavior ScaleAssessing Impulsivity Measurement (UPPS-P-20-R)Recommended by Veli-Matti Karhulahti based on reviews by Ivan Ropovik and Orestis Zavlis
Impulsivity, as a construct, operates by an established history with various models and theories (Leshem & Glicksohn 2007) having accumulated evidence of relevance especially for mental disorders. One of the dominant models, the Impulsive Behavior Model, is conventionally measured in survey studies with UPPS-P scales, a short version of which was recently assessed in a large cross-cultural project (Fournier et al. 2024). In the present study, Fournier and colleagues (2025) aim to further test the revised 20-item scale in English via a three-phase protocol involving evaluations of construct validity, internal consistency reliability, test-retest reliability, convergent validity, and criterion validity. As such, the study contributes to ongoing important development of useful and up-to-date survey scales, which can help researchers avoid measurement issues (Flake & Fried 2020) in various fields where, in this case, impulsivity plays a role.
The study was reviewed over three rounds by two reviewers, with respective topic and methods expertise. Based on detailed responses to reviewers’ feedback and the recommender’s comments on the construct, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance.

STAGE 1
Disentangling the Influences of Curiosity and Active Exploration on Cognitive Map FormationInvestigating influences of curiosity and active exploration on spatial memoryRecommended by Douglas Markant based on reviews by Alexandr Ten and 2 anonymous reviewers
A growing body of research suggests that feelings of curiosity are associated with better memory for new information. However, while curiosity has been broadly defined as an instrinsic drive to obtain information, much of this existing work has focused on learning of trivia facts or factual information, settings where people have relatively little freedom to actively explore aspects of the environment that generate those feelings of curiosity. In this Stage 1 manuscript, O'Donoghue, Cen, and Gruber (2025) propose to conduct an experiment to examine whether feelings of curiosity promote the formation of cognitive maps when exploring novel spatial environments. Participants will encounter a series of virtual rooms for which they report their level of curiosity before exploring each room. The experiment will compare groups of participants who can actively explore for themselves vs. passive observers of the same exploration patterns. The proposed analyses will examine whether anticipatory curiosity leads to better memory for the spatial environments for both active or passive participants, or if benefits to memory are mediated by active participants' ability to act of their feelings of curiosity through their exploration of the environment. The findings of the study will provide new insight into the mechanisms through which anticipatory curiosity enhances memory.
The Stage 1 submission was evaluated by three expert reviewers. After three rounds of revision, the recommender determined that the manuscript met the Stage 1 criteria and awarded in-principle acceptance (IPA).

STAGE 1
Do Ecological Valid Stop Signals Aid Detour Performance? A Comparison of Four Bird SpeciesWhat is the role of sensory perception in cognitive task performance? An improved replication of detour performance in four different bird speciesRecommended by Dieter Lukas based on reviews by 2 anonymous reviewers
The detour task, where an individual has to navigate 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 but blocked reward, the cognitive underpinnings of this behaviour are as yet not fully understood. In the current study, Dewulf et al. (2023) propose to assess one of the specific cognitive processes that might be involved in this behaviour. Through experimental procedures, they will compare the role of signal detection in inhibitory response performance in a detour task. To assess whether variation in detection of the barrier might be linked to the ecological niche of a species, they will compare four bird species who live in different environments. Individuals from these four species were previously tested in a detour task (Regolin et al. 1994, Zucca et al. 2005), and the proposed research plan therefore also involves a partial replication of previous studies on the same issue, but improving some critical aspects.
The Stage 1 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 1 criteria and therefore awarded in-principle acceptance (IPA).

Do Ecological Valid Stop Signals Aid Detour Performance? A Comparison of Four Bird SpeciesWhat is the role of sensory perception in cognitive task performance? An improved replication of detour performance in four different bird speciesRecommended by Dieter Lukas based on reviews by Christian Nawroth and 1 anonymous reviewer
The 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.

STAGE 1
Do error predictions of perceived exertion inform the level of running pleasure?Does running pleasure result from finding it easier than you thought you would?Recommended by Zoltan Dienes based on reviews by Jasmin Hutchinson and 1 anonymous reviewer
The reward value of a stimulus is based on an error in prediction: Things going better than predicted. Could this learning principle, often tested on short acting stimuli, also apply to a long lasting episode, like going for a run? Could how rewarding a run is be based on the run going better than predicted?
Understanding the conditions under which exercise is pleasurable could of course be relevant to tempting people to do more of it! Brevers et al. (2023) will ask people before a daily run to predict the amount of perceived exertion they will experience; then just after the run, to rate the retrospective amount of perceived exertion actually experienced. The difference between the two ratings is the prediction error.
Participants will also rate their remembered pleasure in running and the authors will investigate whether running pleasure depends on prediction error.
The study plan was refined across four rounds of review, with input from two external reviewers and the recommender, after which it was judged to satisfy the Stage 1 criteria for in-principle acceptance (IPA). URL to the preregistered Stage 1 protocol: https://osf.io/xh724

Does alleviating poverty increase cognitive performance? Short- and long- term evidence from a randomized controlled trialUnderstanding the effect of unconditional cash transfers on cognitionRecommended by Chris Chambers based on reviews by Charlotte Pennington and Matúš Adamkovič
Over the last decade, a growing body of evidence has revealed potential benefits of unconditional cash transfers (UCTs) on a variety of outcomes, including self-reported happiness and life satisfaction (Haushofer & Shapiro, 2016), economic and financial well-being (Blattman et al., 2013; Baird et al., 2018) and educational attainment (Baird et al., 2016). Although the effects of UCTs do not always out-perform rigorous control conditions (Whillans & West, 2022), these findings prompt the question of whether the alleviation of poverty via UCTs can also influence cognitive processing and performance. In the current study, Szaszi et al. propose to analyse the results of a previous randomised trial of UCTs by Blattman et al. (2017) to test whether a $200 lump sum administered to a sample of young men in Liberia carries both short- and long-term benefits for a range of executive functions, including attention, response inhibition, and working memory capacity. The Stage 1 manuscript was evaluated over two rounds of in-depth review.

Does alleviating poverty increase cognitive performance? Short- and long-term evidence from a randomized controlled trialNo strong effect of unconditional cash transfers on cognitionRecommended by Chris Chambers based on reviews by Charlotte Pennington and Matúš Adamkovič
Recent studies have revealed potential benefits of unconditional cash transfers (UCTs) on a variety of health and social outcomes, including self-reported happiness and life satisfaction (Haushofer & Shapiro, 2016), economic and financial well-being (Blattman et al., 2013; Baird et al., 2018) and educational attainment (Baird et al., 2016). Although the effects of UCTs do not always out-perform rigorous control conditions (Whillans & West, 2022), these findings prompt the question of whether the alleviation of poverty via UCTs can also influence cognitive processing and performance.
In the current study, Szaszi et al. analysed the results of a previous randomised trial of UCTs by Blattman et al. (2017) to test whether a $200 lump sum – equivalent to three months of income – administered to a sample of young men in Liberia carries both short- and long-term benefits for a range of executive functions, including attention, response inhibition, and working memory capacity. Overall, the results suggest minimal if any consequences of the intervention – the observed effects of UCTs on cognition were several times smaller than suggested by previous research, and the evidence for a positive effect was inconclusive. Extensive multiverse analyses showed that these findings were robust to a range of alternative analytical specifications, and the authors estimate that a sample size of nearly 5000 would be required to provide strong evidence.
In their Discussion, the authors explore a range of reasons for the negative findings compared with previous research, including the more rigorous and severe causal test enabled by the randomised trial design, the demographic homogeneity of the sample demographic, the use of pen-and-paper tests (cf. computerised tests in previous studies), and the delivery of a lump-sum cash transfer compared with a regular monthly installment. In addition, although the results were negative or inconclusive, there were hints that a positive effect of UCTs may be more evident in some cognitive domains than in others – in this case, potentially benefiting working memory more than inhibitory control. Further research would be required to confirm this hypothesis.
The Stage 2 manuscript was evaluated over one round of in-depth review. Based on the responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

Does Brooding Meaningfully Increase the Likelihood of Believing in a Conspiracy? A Registered ReportDoes brooding increase conspiracy beliefs?Recommended by Chris Chambers based on reviews by Matt Williams and 1 anonymous reviewer
The 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.

Does childhood adversity alter opioid drug reward? A conceptual replication in outpatients before surgeryIs childhood adversity associated with a heightened response to opioids?Recommended by Chris Chambers based on reviews by Zoltan Dienes, Yuki Yamada and 1 anonymous reviewer
A 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. seek to test 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 will test whether patients with greater experience of childhood trauma in turn exhibit a larger mood boost and express greater subjective pleasure following opioid administration. Although not a randomised experimental design, this study provides the opportunity to examine the relationship between opioid response and history of childhood adversity in a naturalistic setting, and thus has the potential to either support or cast doubt on the theory that adversity elevates risk of opioid addiction by altering sensitivity to subjectively pleasurable effects.
Following three rounds of in-depth review, the recommender judged that the manuscript met the Stage 1 criteria and awarded in-principle acceptance (IPA).

Does childhood adversity alter opioid drug reward? A conceptual replication in outpatients before surgeryIs childhood adversity associated with a heightened response to opioids?Recommended by Chris Chambers based on reviews by Zoltan Dienes, Yuki Yamada and 1 anonymous reviewer
A 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.
