The effects of false feedback on state memory distrust toward commission and omission, and recognition memory errorsExploring how feedback on memory accuracy shifts criteriaRecommended by Zoltan Dienes based on reviews by Dan Wright, Romuald Polczyk, Greg Neil and 1 anonymous reviewer
We may not believe what our memory tells us: Memory may deliver a compelling recollection we believe did not happen (we know we were not there at the time); and we may know an event happened that we fail to remember. That is, there can be distrust in remembering and distrust in forgetting. Previous work by the authors has looked at this through a signal detection lens, reporting in separate studies that people who have distrust in remembering have either a high or low criterion for saying "old" (Zhang et al, 2023, 2024). A plausible explanation for these contrasting results is that the criterion can either be the means by which false memories are generated enabling the distrust (low criterion); or rather, in conditions where accuracy is at stake, the means for compensating for the distrust (high criterion).
In the current study by Zhang et al (2025), participants were incentivised to be as accurate as possible, and in a memory test given feedback about commission errors or, in another group, ommission errors. The manipulation check indicated that the feedback did not increase (by a meaningful amount) distrust in remembering or distrust in forgetting, respectively, compared to a no feedback control group. Nonetheless, the authors found that people adjusted the criterion to say "old" in a compensatory way in each group. The possible mechanisms underlying these criterion shifts are discussed by the authors, who grapple with the distinction between response criterion shifts versus genuine meta-memory belief changes, and for the latter case, whether any memory distrust change could be contextual versus global (the manipulation check measured the latter).
The Stage 2 manuscript was evaluated over one round of in-depth review by four reviewers. Based on detailed responses to the reviewers' and recommender's comments, the recommender judged that the manuscript met the Stage 2 criteria for recommendation.

Minimal mindfulness of the world as an active control for a full mindfulness of mental states intervention: A Registered Report and Pilot studyTesting the metacognitive basis and benefits of mindfulness trainingRecommended by Robert McIntosh based on reviews by Chris Noone and Julieta Galante
Mindfulness is inherently metacognitive in that it requires monitoring of one’s own thoughts and attention in order to remain on task. Mindfulness practice is especially metacognitive when focused on internal mental states, rather than on the external world. This Registered Report will compare remote training in mindfulness of mental states with remote training in mindfulness of the world, and a wait list control, to test the idea that mindfulness of mental states has an additional metacognitive component, and that this has benefits for (self-reported) mental health. A comparison of participant expectancies between mindfulness conditions will be used to establish whether mindfulness of the world can be considered a true ‘active control’ condition. Additional comparisons will test whether this mindfulness control has benefits over the (inactive) waiting list condition. The study plan is informed by prior research, including pilot data presented in the Stage 1 report, and a sample of up to 300 participants will be tested. The Stage 1 plan has been evaluated through two round of signed external review, and a further two rounds of minor revisions, with the recommender obtaining specialist advice on key points from a relevant external expert. The recommender has judged that the manuscript now meets all Stage 1 criteria, and has awarded In Principle Acceptance (IPA).

How Does Model (Mis)Specification Impact Statistical Power, Type I Error Rate, and Parameter Bias in Moderated Mediation?Dependence of power and type I error on model misspecification for mediated moderationRecommended by Zoltan Dienes based on reviews by Mijke Rhemtulla, Pier-Olivier Caron and Reny Baykova
Researchers are often interested in moderated mediation. A predictor variable, such as number of counselling sessions, may predict an outcome, such as approach to a feared object, by way of a mediator, for example number of times the object was described in counselling. The strength of mediation in turn may depend on a moderator, such as vividness of imagery: Counselling reduces fear by way of imaginative exposure, particularly in those with vivid imagery. There may be a number of mediators ("indirect" paths), and any or all of these mediators may be moderated. In testing moderated mediation, a statistical model is specified which may or may not match the data generating process; in particular, there may or may not be moderators in the model corresponding to moderators that may or may not exist in the real data generating process, resulting in overspecification (more moderators of the indirect paths in the model than reality), underspecification (less moderators of indirect paths in the model than reality) or complete misspecification (where the moderated indirect paths in the model are not moderated in reality, and vice versa).
Researchers rely on the validity of tests (correct type I error rates), if they use frequentist statistics. Model misspecification may impact the validity of inferential tests for moderated mediation. Similarly, researchers need to be able to assess power for any analysis. In simulating power for mediated moderation, it may be important to know the possible extent to which the model is misspecified, and take this into account in planning numbers of participants. Fossum et al. (2024) will address this important problem with a series of simulations to determine if power is reduced meaningfully with over or under specification, or type I error and parameter estimates are biased for complete misspecification. The Stage 1 manuscript was evaluated over two rounds of in-depth review. Based on detailed responses to reviewers’ and the recommender’s comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance.

Michotte's research on perceptual impressions of causality: a pre-registered replication studyGaining confidence in Michotte’s classic studies on the perception of causalityRecommended by Moin Syed based on reviews by Maxine Sherman and 1 anonymous reviewer
Making 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 (2023) proposes a series of experiments to replicate and extend 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 subjected 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 has proposed an ambitious set of 14 experiments that directly replicate and, in some cases, extend Michotte’s experiments.
The Stage 1 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 1 criteria and was therefore awarded in-principle acceptance (IPA).

Michotte's research on perceptual impressions of causality: a registered replication studyMichotte’s classic studies on the perception of causality: Replications, extensions and a sound base for further researchRecommended by Moin Syed based on reviews by Maxine Sherman and 1 anonymous reviewer
Making 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.

Neophobia across social contexts in juvenile Herring gullsHerring gulls exhibit reduced neophobia when tested in groupsRecommended by Ljerka Ostojic based on reviews by Claudia Mettke-Hofmann and 1 anonymous reviewer
How well animals may be able to cope with changes of habitat, specifically with rapid changes and thus novelty they encounter in an environment densely populated by humans, may be influenced by how they respond to novelty in general (Batisteli et al., 2022; Biondi et al., 2024; Castano et al., 2024; Heales et al., 2024). In considering this, it may be important to account for any difference in behavioural responses that animals exhibit when encountering a novel situation alone versus when they are doing so as part of a group.
Here, Allaert et al. (2025) tested how neophobia – the fear of unfamiliar objects – is affected by the social context in gulls, birds that are increasingly forced to live in urban environments due to the loss of natural coastlines. In this study, in which they reared herring gulls from egg and tested them taking into account that nestmates are not tested within the same groups, the authors found that the birds were faster to eat and spent more time in the zone of interest when they were tested in a group than when they were tested individually, specifically when a novel object was placed next to the food compared to when that object was a familiar one. The birds were also faster to enter the testing area when tested in a group, but this was not specific to the novel object condition. In addition to these changes in the average responses, the authors also report reduced variance when tested in a group in two of their three measures, namely in the latency to enter the testing area and time spent in the zone of interest.
The authors interpret their findings as being mostly in line with the ‘risk-dilution’ hypothesis, which is often considered in terms of predation risk (Krause & Buxton, 2002). They discuss possible reasons why other studies, with different species and different methodological setups, found support for alternative explanations.
The Stage 2 report was evaluated by the same two reviewers who had also reviewed the Stage 1 manuscript. In the revision, the authors focused on adding sex as a factor in their statistical models, which was the planned procedure for the statistical analyses in the Stage 1 report, and adding information regarding the problems encountered during testing and how these were handled. This specifically refers to the planned sample size (which the authors planned in the Stage 1 report taking into account both mortality and the fact that some birds would be not herring gulls but lesser black-backed gulls, which can only be established after hatching). However, there was higher than expected mortality, leading to a larger-than-planned overall reduction in sample size. During the study, the authors had contacted the recommender and discussed this issue, and the recommender advised on continuing the study and approved of the planned changes in the Stage 2 report. During the revision process, the authors added more information and also conducted an exploratory analysis, which included all birds, i.e. herring gulls and lesser black-backed gulls. This was suggested by a reviewer and the authors present this exploratory analysis in full in the supplemental material, while the main inferences are presented in the main text. In addition, during the Stage 2 review it became apparent that some minor details regarding the procedure would be useful to be included in the Stage 2 report, which the authors included in the Stage 2 revision. This did not alter the procedure as described in the Stage 1 report, but merely added more clarity to the text.
Based on detailed engagement with these points and the reviewers' comments, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

STAGE 1
Neophobia across social contexts in juvenile Herring gullsDoes social context influence neophobia in juvenile herring gulls (Larus argentatus)?Recommended by Ljerka Ostojic based on reviews by 2 anonymous reviewers
Many animals are increasingly reliant on living close or in urban environments. For them, neophobia – a trait that denotes the fearfulness of novelty (Mettke-Hoffmann, 2022) – may influence how well the species but also individuals of the same species adjust to the (human-induced) changes that characterise these environments (Lowry et al., 2013).
Typically, neophobia in non-human animals is assessed through behavioural tests, most often by measuring the time it takes an individual to approach a novel object or food that is positioned next to a novel object. Increasingly, resarchers are acknowledging that the social context may influence the behaviour of individuals in such situations, and several hypotheses have been proposed to explain a potential influence of social context on neophobic responses.
In the current study, Allaert et al. (2024) will use a within-subject design to test three hypotheses with juvenile herring gulls (Larus argentatus): 1) the risk dilution hypothesis, accoding to which gulls will exhibit smaller neophobic responses when tested in a group than when tested alone, 2) the negotiation hypothesis, according to which gulls will exhibit stronger neophobic responses when tested in a group than when tested alone, and 3) the social conformity hypothesis, according to which those more neophobic individuals will show a smaller neohobic response when tested in a group than when tested alone while less neophobic individuals will exhibit the opposite pattern.
The Stage 1 manuscript was evaluated by two reviewers over two rounds of revisions. During the revisions, the authors clarified the conceptual arguments of the manuscript (including why juveniles are being tested), and edited the methods, including timing of testing, adjustments to the way that the experimental and control conditions will be run, how the planned sample size will be ensured given that at the time of testing, some chicks may be of a different species (this will become evident later on), how relatedness between the chicks will be dealt with, as well as how the behavioural coding will be conducted. Thus, the recommender judged that the manuscript met the Stage 1 criteria and awarded in-principle acceptance (IPA).

Dose-response of tDCS effects on motor learning and cortical excitability: a preregistered studyHow stimulation intensity affects motor learningRecommended by Christina Artemenko based on reviews by Charlotte Wiltshire and 1 anonymous reviewer
In 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).

Cerebral laterality as assessed by functional transcranial Doppler ultrasound in left-and right-handers: A comparison between handwriting and writing using a smartphoneDoes typing on a smartphone involve the same neural mechanisms as writing by hand?Recommended by D. Samuel Schwarzkopf based on reviews by Todd Richards and Dorothy Bishop
Language production is associated with a distinct lateralised pattern of brain activation biased toward the left cerebral hemisphere. This also applies to writing. It has also been shown to be modulated by handedness, with less pronounced lateralisation in left-handers. However, in recent decades the use of handwriting has declined significantly while the use of smartphones has exploded. To date, no study has explored whether the same neural correlates of written language production found for handwriting also hold for typing on a smartphone.
In the current study, Samsouris et al. (2023) will use functional transcranial Doppler ultrasound (fTCD) to measure blood flow velocity within cerebral hemispheres to investigate this question. This technique is particularly suited for this purpose because it provides better control for the movement confounds associated with a writing task and the technical challenges of using a smart device than other neuroimaging techniques like fMRI or M/EEG. The authors hypothesise that there will be no difference in left cerebral lateralisation for handwriting and typing on a smartphone. They also expect to replicate previous findings of weaker lateralisation in left-handers in written language production when typing on a smartphone. To isolate the effect of written language production, both these conditions will be corrected for their corresponding motor component using control conditions without a linguistic component.
The Stage 1 manuscript was evaluated over 6 rounds of in-depth review by the recommender and two expert reviewers, before issuing in-principle acceptance.

Replicating the facilitatory effects of transcranial random noise stimulation on motion processing: A registered reportTesting the facilitatory effect of high-frequency transcranial random noise stimulation through enhancement of global motion processingRecommended by Robert McIntosh based on reviews by Sam Westwood and Filippo Ghin
High frequency transcranial random noise stimulation (hf-tRNS) is a relatively novel form of non-invasive brain stimulation, thought to enhance neural excitability and facilitate processing in targeted brain areas. The evidence for the efficacy of hf-tRNS is mixed, so a high-powered test of the proposed facilitatory effects would be of value to the field. This Registered Report will target the human middle temporal complex (hMT+), an area with a well-established critical role in global motion processing. The protocol is adapted from a study by Ghin and colleagues (2018) but focusing on a sub-set of the original experimental conditions and using a fully within-subjects design (n=42). Global motion processing will be operationalised in terms of the coherence threshold for identification of the dominant direction of random-dot motion. The experiment will test the predicted facilitation of contralateral motion processing (reduced coherence threshold) during hf-tRNS to the left hMT+. The specificity of this effect will be tested by comparison to a sham stimulation control condition and an active stimulation control condition (left forehead). By targeting a brain area with a well-established critical role in behaviour, this study will provide important information about the replicability and specificity of the facilitatory effects of hf-tRNS.
Following two rounds of in-depth review, the recommender judged that the manuscript met the Stage 1 criteria and awarded in-principle acceptance (IPA).
