One and only SNARC? Spatial-Numerical Associations are not fully flexible and depend on both relative and absolute magnitudeA Registered Report demonstration that the SNARC effect depends on absolute as well as relative number magnitudeRecommended by Robert McIntosh based on reviews by Claudia Gianelli
The Spatial-Numerical Association of Response Codes (SNARC) effect refers to the fact that smaller numbers receive faster responses with the left hand, and larger numbers with the right hand (Dehaene et al., 1993). This robust finding implies that numbers are associated with space, being represented on a mental number line that progresses from left to right. The SNARC effect is held to depend on relative number magnitude, with the mental number line dynamically adjusting to the numerical range used in a given context. This characterisation is based on significant effects of relative number magnitude, with no significant influence of absolute number magnitude. However, a failure to reject the null hypothesis is not firm evidence for the absence of an effect. In this Registered Report, Roth and colleagues (2024) report two large-sample online experiments, with a Bayesian statistical approach to confirm—or refute—a role for absolute number magnitude in modulating the classic SNARC effect (smallest effect size of interest, d = 0.15).
Experiment 1 closely followed Dehaene’s (1993) original methods, and found strong evidence for an influence of relative magnitude, and moderate-to-strong evidence against an influence of absolute magnitude. Experiment 2 was designed to exclude some potential confounds in the original method, and this second experiment found strong evidence for both relative and absolute magnitude effects, of comparable effect sizes (in the range of d = .24 to .42). This registered study demonstrates that the SNARC effect is not ‘fully flexible’, in the sense of depending only on relative number magnitude; it is also shaped by absolute magnitude.
This Stage 2 manuscript was evaluated by the recommender and one external reviewer. Following appropriate minor revisions, the recommender judged that the manuscript met the Stage 2 criteria for recommendation.

STAGE 1
Barriers and facilitators to the adoption and promotion of Open Science practices in psychology. The case of SlovakiaWhat are the barriers and facilitators to open science practices for researchers, policy makers and media representatives in Slovakia?Recommended by Charlotte Pennington based on reviews by Crystal Steltenpohl, Peter Branney, Andrea E. Abele-Brehm , Emma Norris and 1 anonymous reviewer
Open science practices (OSPs, e.g., preregistration, open materials, code and data) aim to enhance the transparency, integrity, and reproducibility of research. Recent work, however, has highlighted various facilitators and barriers perceived by researchers in implementing these, which can either enhance or hinder their success. Little is known about these barriers in the context of Slovakia, and such perceptions are rarely investigated for policy makers and media representatives who are also embedded in the research ecosystem.
In their Stage 1 Registered Report, Marcel Martončik and colleagues aim to map the perceptions and experiences of barriers and facilitators of OSPs that are unique to different stakeholder groups in Slovakia. They will conduct both semi-structured interviews and focus groups with a diverse sample of postgraduate students, researchers, policymakers, and media representatives from the field of psychology. Reflexive thematic analysis will identify overarching themes regarding such barriers and facilitators which will provide valuable insights into the support required to make OSPs normative across different stakeholder groups.
Four expert reviewers assessed the Stage 1 manuscript across two rounds of in-depth review. Based on the authors' detailed and informed responses to the reviewer’s comments, the recommender judged that the manuscript met the Stage 1 criteria and awarded in principle acceptance (IPA).

STAGE 1
Replication of “Carbon-Dot-Based Dual-Emission Nanohybrid Produces a Ratiometric Fluorescent Sensor for In Vivo Imaging of Cellular Copper Ions”Replicating, Revising and Reforming: Unpicking the Apparent Nanoparticle Endosomal Escape ParadoxRecommended by Emily Linnane and Yuki Yamada based on reviews by Cecilia Menard-Moyon and Zeljka Krpetic
Context
Over the past decade there has been an exponential increase in the number of research papers utlising nanoparticles for biological applications such as intracellular sensing [1, 2], theranostics [3-5] and more recently drug delivery and precision medicine [6, 7]. Despite the success stories, there is a disconnect regarding current dogma on issues such as nanoparticle uptake and trafficking, nanoparticle delivery via the enhanced permeability and retention (EPR) effect, and endosomal escape. Critical re-evaluation of these concepts both conceptually and experimentally is needed for continued advancement in the field.
For this preregistration, Said et al. (2024) focus on nanoparticle intracellular trafficking, specifically endosomal escape [8]. The current consensus in the literature is that nanoparticles enter cells via endocytosis [9, 10] but reportedly just 1-2% of nanoparticles/ nanoparticle probes escape endosomes and enter the cytoplasm [11-13]. There is therefore an apparent paradox over how sensing nanoparticles can detect their intended targets in the cytoplasm if they are trapped within the cell endosomes. To address this fundamental issue of nanoparticle endosomal escape, Lévy and coworkers are carrying out replication studies to thoroughly and transparently replicate the most influential papers in the field of nanoparticle sensing. The aim of these replication studies is twofold: to establish a robust methodology to study endosomal escape of nanoparticles, and to encourage discussions, transparency and a step-change in the field.
Replication of “Carbon-Dot-Based Dual-Emission Nanohybrid Produces a Ratiometric Fluorescent Sensor for In Vivo Imaging of Cellular Copper Ions”
For this replication study, the authors classified papers on the topic of nanoparticle sensing and subsequently ranked them by number of citations. Based on this evaluation they selected a paper by Zhu and colleagues [14] entitled “Carbon-Dot-Based Dual-Emission Nanohybrid Produces a Ratiometric Fluorescent Sensor for In Vivo Imaging of Cellular Copper Ions” for their seminal replication study. To determine the reproducibility of the results from Zhu et al., the authors aim to establish the proportion of endosomal escape of the nanoparticles, and to examine the data in a biological context relevant to the application of the probe.
Beyond Replication
The authors plan to replicate the exact conditions reported in the materials and methods section of the selected paper such as nanoparticle probe synthesis of CdSe@C-TPEA nanoparticles, assessment of particle size, stability and reactivity and effect on cells (TEM, pH experiments, fluorescent responsivity to metal ions and cell viability). In addition, Said et al., plan to include further experimental characterisation to complement the existing study by Zhu and colleagues. They will incorporate additional controls and methodology to determine the intracellular location of nanoparticle probes in cells including: quantifying excess fluorescence in the culture medium, live cell imaging analysis, immunofluorescence with endosomal and lysosomal markers, and electron microscopy of cell sections. The authors will also include supplementary viability studies to assess the impact of the nanoparticles on HeLa cells as well as an additional biologically relevant cell line (for use in conjunction with the HeLa cells as per the original paper).
The Stage 1 manuscript underwent two rounds of thorough in-depth review. After considering the detailed responses to the reviewers' comments, the recommenders determined that the manuscript met the Stage 1 criteria and awarded in-principle acceptance (IPA).
The authors have thoughtfully considered their experimental approach to the replication study, whilst acknowledging any potential limitations. Given that conducting such a replication study is novel in the field of Nanotechnology and there is currently no ‘gold standard’ approach in doing so, the authors have showed thoughtful regard of statistical analysis and unbiased methodology where possible.
Based on current information, this study is the first use of preregistration via Peer Community in Registered Reports and the first formalised replication study in Nanotechnology for Biosciences. The outcomes of this of this study will be significant both scientifically and in the wider context in discussion of the scientific method.

STAGE 1
Probing the dual-task structure of a metacontrast-masked priming paradigm with subjective visibility judgmentsDo trial-wise visibility reports - and how these reports are made - alter unconscious priming effects?Recommended by D. Samuel Schwarzkopf based on reviews by Markus Kiefer, Thomas Schmidt and 3 anonymous reviewers
Many studies of unconscious processing measure priming effects. Such experiments test whether a prime stimulus can exert an effect on speeded responses to a subsequently presented target stimulus even when participants are unaware of the prime. In some studies, participants are required to report their awareness of the prime in each trial - a dual-task design. Other studies conduct such visibility tests in separate experiments, so that the priming effect is measured via a single task. Both these approaches have pros and cons; however, it remains unclear to what extent they can affect the process of interest. Can the choice of experimental design and its parameters interfere with the priming effect? This could have implications for interpreting such effects, including in previous literature.
In the current study, Wendt and Hesselmann (2024) will investigate the effects of using a dual-task design in a masked priming paradigm, focusing on subjective visibility judgments. Based on power analysis, the study will test 34 participants performing both single-task and several dual-task conditions to measure reaction times and priming effects. Priming is tested via a speeded forced-choice identification of a target. The key manipulation is the non-speeded visibility rating of the prime using a Perceptual Awareness Scale, either with a graded (complex) rating or a dichotomous response. Moreover, participants will either provide their awareness judgement via a keyboard or vocally. Finally, participants will also complete a control condition to test prime visibility by testing the objective identification of the prime. These conditions will be presented in separate blocks, with the order randomised across participants. The authors hypothesise that using a dual-task slows down response times and boosts priming effects. However, they further posit that keyboard responses and graded visibility ratings, respectively, in the dual task reduce priming effects (but also slow response times) compared to vocal responses and dichotomous visibility judgements. In addition to the preregistered hypotheses, the study will also collect EEG data to explore the neural underpinnings of these processes.
The Stage 1 manuscript went through three rounds of review by the recommender and five expert reviewers. While the recommender would have preferred to see targeted, directional hypotheses explicitly specified in the design instead of non-directional main effects/interactions, he nevertheless considers this experimental design ready for commencing data collection, and therefore granted in-principle acceptance.

From Thought to Senses: Assessing the Presence of a Relationship Between the Generation Effect and Multisensory FacilitationExploring multi-sensory benefits in the generation effect of memoryRecommended by Gidon Frischkorn based on reviews by Vanessa Loaiza, Sharon Bertsch and Vanessa Loaiza
This study by Ritchie and Wilbiks (2024) investigates whether the generation effect, a memory advantage for self-generated verbal information, is enhanced under multisensory conditions. It is designed to explore a gap in the literature regarding the interplay between the generation effect and multisensory facilitation, with potential applications in educational settings.
Exploring multisensory aspects of the generation effect, the study has the potential to provide new insights into cognitive processing and memory enhancement. It is well rooted in established theories of the generation effect and multisensory facilitation, deducing a reasonable hypothesis that multisensory processing amplifies the generation effect. By implementing a 2 (Task Type: generate vs. read) x 3 (Sensory Modality: auditory, visual, multisensory) factorial design, it ensures a comprehensive evaluation of multisensory benefits in the generation effect. The findings could inform multisensory learning strategies in educational contexts, enhancing teaching methods and learning outcomes. Based on these considerations and two rounds of in-depth review, the recommender awarded in-principle acceptance of the study proposal. Its strong theoretical foundation and well-conceived methodology make it a valuable contribution to the fields of cognitive and educational psychology.

Associations between anxiety-related traits and fear acquisition and extinction - an item-based content and meta-analysisIntegrative meta-analysis of anxiety-related traits and fear processing: bridging research to clinical applicationRecommended by Sara Garofalo based on reviews by Yoann Stussi, Luigi Degni, Marco Badioli and 1 anonymous reviewer
The paper aims to bridge gaps in understanding the relationship between anxiety-related traits and fear processing, with a specific focus on fear acquisition and extinction. Fear and safety processing are known to be linked to anxiety symptoms and traits such as neuroticism and intolerance of uncertainty (Lonsdorf et al., 2017; Morriss et al., 2021). However, the diversity in study focus and measurement methods makes it difficult to integrate findings into clinical practice effectively.
To address this issue, Brunsch et al. (2024) propose a systematic literature search and meta-analysis, following PRISMA guidelines, to explore these associations. They plan to use nested random effects models to analyze both psychophysiological and self-report outcome measures. Additionally, they will examine the role of different questionnaires used to assess anxiety-related traits and conduct a content analysis of these tools to evaluate trait overlaps.
Current knowledge from the literature indicates that individuals with anxiety disorders exhibit differences in fear acquisition and extinction compared to those without such disorders (Lonsdorf et al., 2017; Morriss et al., 2021). Previous meta-analyses have shown associations between anxiety traits and fear generalization/extinction, but these studies are limited in their scope and focus.
The primary aim of the research is to provide a comprehensive summary of the associations between anxiety-related traits and conditioned responding during fear acquisition and extinction across multiple measures. Another goal is to investigate whether different anxiety-related trait questionnaires yield different associations with fear and extinction learning. The authors will also conduct a content analysis to better interpret the results of their meta-analysis by examining the overlap in questionnaire content.
A secondary aim of the study is to evaluate how sample characteristics, experimental specifics, and study quality influence the associations between anxiety-related traits and fear acquisition and extinction. By addressing these aims, the study seeks to advance the understanding of fear-related processes in anxiety and inform more targeted prevention and intervention strategies.
The Stage 1 manuscript underwent two rounds 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).

Impact of analytic decisions on test-retest reliability of individual and group estimates in functional magnetic resonance imaging: a multiverse analysis using the monetary incentive delay taskExploring determinants of test-retest reliability in fMRI: a study with the Monetary Incentive Delay TaskRecommended by Dorothy Bishop based on reviews by Xiangzhen Kong and 1 anonymous reviewer
Functional magnetic resonance imaging has been used to explore brain-behaviour relationships for many years, with proliferation of a wide range of sophisticated analytic procedures. However, rather scant attention has been paid to the reliability of findings. Concerns have been growing failures to replicate findings in some fields, but it is hard to know how far this is a consequence of underpowered studies, flexible analytic pipelines, or variability within and between participants. Demidenko et al. (2024) took advantage of the availability of three existing datasets, including the Adolescent Brain Cognitive Development (ABCD) study, the Michigan Longitudinal Study, and the Adolescent Risk Behavior Study, which all included a version of the Monetary Incentive Delay task measured in two sessions. These were entered into a multiverse analysis, which considered how within-subject and between-subject variance varies according to four analytic factors: smoothing (5 levels), motion correction (6 levels), task modelling (3 levels) and task contrasts (4 levels). They also considered how sample size affects estimates of reliability. The results have important implications for the those using fMRI with the Monetary Incentive Delay Task, and also raise questions more broadly about use of fMRI indices to study individual differences. Motion correction had relatively little impact on the ICC, and the effect size of the smoothing kernel was modest. Larger impacts on reliability were associated with choice of contrast (implicit baseline giving larger effects) and task parameterization. But perhaps the most sobering message from this analysis is that although activation maps from group data were reasonably reliable, the ICC, used as an index of reliability for individual levels of activation, was consistently low. This raises questions about the suitability of the Monetary Incentive Delay Task for studying individual differences. Another point is that reliability estimates become more stable as sample size increases; researchers may want to consider whether the trade-off between cost and gain in precision is justified for sample sizes above 250. I did a quick literature search on Web of Science: at the time of writing the search term ("Monetary Delay Task" AND fMRI) yielded 410 returns, indicating that this is a popular method in cognitive neuroscience. The detailed analyses reported here will repay study for those who are planning further research using this task. The Stage 2 manuscript was evaluated over one round of in-depth review. Based on detailed responses to the reviewer's and recommender's comments, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

Test-Retest Reliability in Functional Magnetic Resonance Imaging: Impact of Analytical Decisions on Individual and Group Estimates in the Monetary Incentive Delay TaskExploring determinants of test-retest reliabilty in fMRIRecommended by Dorothy Bishop based on reviews by Xiangzhen Kong and 2 anonymous reviewers
Functional magnetic resonance imaging (fMRI) has been used to explore brain-behaviour relationships for many years, with proliferation of a wide range of sophisticated analytic procedures. However, rather scant attention has been paid to the reliability of findings. Concerns have been growing following failures to replicate findings in some fields, but it is hard to know how far this is a consequence of underpowered studies, flexible analytic pipelines, or variability within and between participants.
Demidenko et al. (2023) plan a study that will be a major step forward in addressing these issues. They take advantage of the availability of three existing datasets, the Adolescent Brain Cognitive Development (ABCD) study, the Michigan Longitudinal Study, and the Adolescent Risk Behavior Study, which all included a version of the Monetary Incentive Delay task measured in two sessions. This gives ample data for a multiverse analysis, which will consider how within-subject and between-subject variance varies according to four analytic factors: smoothing (5 levels), motion correction (6 levels), task modelling (3 levels) and task contrasts (4 levels). They will also consider how sample size affects estimates of reliability. This will involve a substantial amount of analysis.
The study is essentially focused on estimation, although specific predictions are presented regarding the combinations of factors expected to give optimal reliability. The outcome will be a multiverse of results which will allow us to see how different pipeline decisions for this task affect reliability. In many ways, null results – finding that at least some factors have little effect on reliability – would be a positive finding for the field, as it would mean that we could be more relaxed when selecting an analytic pathway. A more likely outcome, however, is that analytic decisions will affect reliability, and this information can then guide future studies and help develop best practice guidelines. As one reviewer noted, we can’t assume that results from this analysis will generalise to other tasks, but this analysis with a widely-used task is an important step towards better and more consistent methods in fMRI.
The researchers present a fully worked out plan of action, with supporting scripts that have been developed in pilot testing. The Stage 1 manuscript received in-depth evaluation from three expert reviewers and the recommender. 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).

The Influence of Bilingualism on Statistical Word Learning: A Registered ReportComparing statistical word learning in bilinguals and monolingualsRecommended by Elizabeth Wonnacott based on reviews by 2 anonymous reviewers
Many studies have investigated the extent to which word learning is underpinned by statistical learning, i.e. tracking probabilistic relationships between forms and referents. Previous literature has investigated whether these processes differ in bilingual learners – who have to track two such sets of mappings in their linguistic environment. However, the evidence is mixed: some say bilinguals have a learning advantage and some find no evidence of differences.
The current study by Simonetti et al. (2024) aims to further explore this in an experiment using the cross-situational word learning paradigm. In this paradigm participants hear words and view arrays of object across a series of trials. Taking each trial in isolation the word is ambiguous, but there are consistent co-occurrences of words with referents across the trials. Two groups of participants will be compared: monolingual English speaker and English-German bilinguals. Using this paradigm, the study can track learning over time as well as looking at individual trial by trial analyses. The researchers predict specifically that bilingual learners will have a specific advantage in learning 1:2 mappings, where one-word maps to two objects. The study will use Bayes Factors as the method of inference when analysing the data, allowing them to differentiate evidence for "no difference" from ambiguous evidence from which no conclusion can be drawn.
The Stage 1 manuscript was evaluated over four 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 awarded in-principle acceptance (IPA).

Learning from comics versus non-comics material in education: Systematic review and meta-analysisComics in EducationRecommended by Veli-Matti Karhulahti based on reviews by Adrien Fillon, Benjamin Brummernhenrich, Solip Park and Pavol Kačmár
Especially after the impactful experiments in modern comics (e.g. McCloud 1993), research interest in the medium increased with new practical developments (Kukkonen 2013). Some of these developments now manifest in educational settings where comics are used for various pedagogical purposes in diverse cultural contexts. To what degree comics are able to reach educational outcomes in comparison to other pedagogical tools remains largely unknown, however.
In the present registered report, Pagkratidou and colleagues (2024) respond to the research gap by investigating the effectiveness of educational comics materials. By means of systematic review and meta-analysis, the authors assess all empirical studies on educational comics to map out what their claimed benefits are, how the reported effectiveness differs between STEM and non-STEM groups, and what moderating effects complicate the phenomenon. With the help of large language models, all publication languages are included in analysis. The research plan was reviewed over three rounds by four reviewers with diverse sets of expertise ranging from education and meta-analytic methodology to comics culture and design. After comprehensive revisions by the authors, the recommender considered the plan to meet high Stage 1 criteria and provided in-principle acceptance.

At least some data/evidence that will be used to the answer the research question has been previously accessed by the authors (e.g. downloaded or otherwise received), but the authors certify that they have not yet observed ANY part of the data/evidence.
