STAGE 1
The origin of symbolic numerical knowledge in early development – an fNIRS Registered Report
An fNIRS test of the neural correlates of the Cardinality Principle in typically-developing children
Recommended by Robert McIntosh based on reviews by Ed Hubbard and 1 anonymous reviewerThe cardinality principle (CP) is a key concept in numerical cognition, which children typically acquire by the age of five. This is the understanding that each number in a counted sequence refers to a specific set of items, and that the final number represents the total size of the set. Here, Ivanova and colleagues (2024) propose an experiment to study the changes in neural activity that accompany the acquisition of this concept, focusing on activity within the parietal lobes as measured by functional near-infrared spectroscopy (fNIRS).
Typically-developing children aged from 2 years 9 months to 4 years 9 months will be assessed for their ability to give a specific number of balls from a pile: those who can give five or more correctly will be classified as CP-knowers, and those who can only give lower set sizes will be classified as subset-knowers. All children will then perform an auditory number word adaptation task while undergoing fNIRS. The adaptation task involves hearing the number word ‘two’ repeated, interspersed with deviant number words (‘four’ or ‘eight’) or a non-number word (‘rin’). The experimental hypotheses are that left parietal activations and bilateral parietal functional connectivity will be differentially greater for number than non-number deviants amongst CP-knowers than amongst subset-knowers. Each hypothesis will be tested by sequential Bayes factor analysis, with a minimum of 25 and a maximum of 46 participants per group, providing high sensitivity to detect a smallest effect size of d = .35. This study aims to provide insights into the neural underpinnings of the CP, informing theoretical models of symbolic knowledge acquisition.
The study plan was refined over four rounds of review, with input from two external reviewers, after which the recommender judged that the Stage 1 manuscript met the criteria for in-principle acceptance (IPA).

One and only SNARC? Spatial-Numerical Associations are not fully flexible and depend on both relative and absolute magnitude
A Registered Report demonstration that the SNARC effect depends on absolute as well as relative number magnitude
Recommended by Robert McIntosh based on reviews by Claudia GianelliThe 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.

Does ‘virtuality’ affect the role of prior expectations in perception and action? Comparing predictive grip and lifting forces in real and virtual environments
The role of prior expectations for lifting objects in virtual reality
Recommended by Robert McIntosh based on reviews by 2 anonymous reviewersAs virtual reality environments become more common, it is important to understand our sensorimotor interactions with them. In real world settings, sensory information is supplemented by prior expectations from past experiences, aiding efficient action control. In VR, the relative role of expectations could decrease due to a lack of prior experience with the environment, or increase because sensory information is impoverished or ambiguous. Harris, Arthur and Buckingham (2024) propose to test these possibilities by comparing a real-world object lifting task and a VR version in which the same objects are lifted but visual feedback is substituted by a virtual view. The experiment uses the Size-Weight Illusion (SWI) and the Material Weight Illusion (MWI). In these paradigms, the visual appearance of the object induces expectations about weight that can affect the perception of weight during lifting, and the fingertip forces generated. The degree to which the visual appearance of objects induces differences in perceived weight, and in measured fingertip forces, will index the influence of prior expectations for these two paradigms. The analyses will test whether the influence of prior expectations is lower or higher in the VR set-up than in real-world lifting. The outcomes across tasks (SWI and MWI) and measures (perceived weight, fingertip forces) will broaden our understanding of the role of predictive sensorimotor control in novel virtual environments.
After three rounds of evaluation, with input from two external reviewers, the recommender judged that the Stage 1 manuscript met the criteria for in-principle acceptance (IPA).

The importance of conceptual knowledge when becoming familiar with faces during naturalistic viewing
A registered test of the role of contextual information in perceptual learning of faces
Recommended by Robert McIntosh based on reviews by Haiyang JinWhen we familiarise with new faces over repeated exposures, it is generally in situations that have meaning for us. Seeing a face more often tends to go along with learning more about the person, and their likely contexts and actions. In this Registered Report, Noad and Andrews (2024) tested whether meaningful context during exposure improves the consolidation of faces into long-term memory. Participants were shown video clips from the TV series Life on Mars, either in their original chronological sequence, which provides meaningful context, or in a scrambled sequence. It was expected that the original sequence would provide a better conceptual understanding, and this was confirmed by free recall and structured question tests. Face recognition memory was tested with images of the actor from the original clips (‘in show’) and the same actor from another show (‘out-of-show’), to test whether memory was modulated by the similarity of appearance to that at encoding. Face recognition was tested immediately after exposure and after four weeks, to allow time for consolidation. As expected, recognition memory was better for participants in the meaningful context condition, and for in-show faces. However, meaningful context did not lead to less forgetting of the faces at the follow up test, even for in-show faces, which did not support the original predictions. An exploratory analysis found that a metric of overlap between pairs of participants’ conceptual understanding was related to overlap in the set of faces they recognised. This relationship was stronger after four weeks, which suggests increased interaction of conceptual knowledge and face recognition after consolidation.
The Stage 2 manuscript was assessed over two rounds of review, and the recommender judged that the manuscript met the Stage 2 criteria for recommendation.

STAGE 1
The importance of consolidating perceptual experience and contextual knowledge in face recognition
How does perceptual and contextual information influence the recognition of faces?
Recommended by Robert McIntosh based on reviews by Lisa DeBruine and Haiyang JinWhen we familiarise with new faces over repeated exposures, it is in situations that have meaning for us. Here, Noad and Andrews (2023) ask whether meaningful context during exposure matters for the consolidation of faces into long-term memory. Participants will be shown video clips from TV shows that are ordered either in their original chronological sequence, preserving meaningful context, or in a scrambled sequence. It is expected that the original sequence will provide a better understanding of the narrative. The critical question is whether this will also be associated with differences in memory for the faces. Memory will be tested with images of the actor from the original clips (‘in show’) or images of the same actor from another show (‘out-of-show’), both immediately after exposure and following a four-week delay. It is predicted that memory for faces will be better retained across the delay when the original exposure was in a meaningful context, and that this benefit will be enhanced for ‘in-show’ images, where the person’s appearance matches with the original context. The pre-registered predictions and the targeted effect sizes for this study are informed by pilot data reported within the manuscript.
The Stage 1 manuscript was evaluated through an initial round of editorial review, followed by a further round of external review, after which the recommender judged that it met the Stage 1 criteria for in-principle acceptance (IPA).

Functional MRI brain state occupancy in the presence of cerebral small vessel disease -- a pre-registered replication analysis of the Hamburg City Health Study
Replicable dynamic functional connectivity and cognitive correlates of cerebral small vessel disease in the Hamburg City Health Study
Recommended by Robert McIntosh based on reviews by 1 anonymous reviewerIn a previous analysis of data from 988 participants in the Hamburg City Health Study (HCHS), Schlemm and colleagues (2022) reported significant associations between the extent of cerebral small vessel disease (cSVD) and dynamic functional connectivity measures from resting state fMRI. Specifically, the volume of white matter hyperintensities of presumed vascular origin, a structural indicator of cSVD, was negatively related to the proportion of time (‘fractional occupancy’) spent in the two most occupied functional brain states. Reduced fractional occupancy was also associated with longer times to complete part B of the Trail Making Test.
In the present Registered Report, Ingwersen and colleagues (2023) successfully replicated these associations between structural, functional and cognitive measures in a sample of 1651 HCHS participants not included in the earlier study. An exploratory multiverse analysis found that the associations were generally robust to different brain parcellation and confound regression strategies. These replicable patterns reinforce the idea that cSVD may disrupt the brain’s ability to enter and maintain distinct functional modes, and that these changes in functional dynamics are predictive of cognitive impairment.
The Stage 2 manuscript was assessed over one round of in-depth review. The recommender judged that responses to reviewer comments were appropriate, and that the manuscript met the Stage 2 criteria for recommendation.

One and only SNARC? A Registered Report on the SNARC Effect’s Range Dependency
Is the SNARC effect modulated by absolute number magnitude?
Recommended by Robert McIntosh based on reviews by Melinda Mende and 1 anonymous reviewerThe 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, within the standard frequentist statistical framework, is not firm evidence for the absence of an effect. In this Stage 1 Registered Report, Roth and colleagues (2023) propose two experiments adapted from Dahaene’s (1993) original methods, with a Bayesian statistical approach to confirm—or rule out—a small effect (d = 0.15) of absolute number magnitude in modulating the classic SNARC effect.
The study plan was refined across two 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).

Evaluation of spatial learning and wayfinding in a complex maze using immersive virtual reality. A registered report
Evaluation of an immersive virtual reality wayfinding task
Recommended by Robert McIntosh based on reviews by Conor Thornberry, Gavin Buckingham and 1 anonymous reviewerThe Virtual Maze Task (VMT) is a digital desktop 2D spatial learning task that has been used for research into the effect of sleep and dreaming on memory consolidation (e.g. Wamsley et al, 2010). One limitation of this task has been low rates of reported dream incorporation. Eudave and colleagues (2023) have created an immersive virtual reality (iVR) version of the VMT, which they believe might be more likely to be incorporated into dreams. As an initial step in validating this task for research, they propose a within-subjects study to compare three measures of spatial learning between the 2D desktop and iVR versions. Based on a review of relevant literature, the prediction is that performance will be similar between the two task versions. The planned sample size (n = 62) is sufficient for a .9 power test of equivalence within effect size bounds of d = -.47 to .47. Additional independent variables (gender, perspective-taking ability) and dependent measures (self-reported cybersickness and sense of presence) will be recorded for exploratory analyses.
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).†

Functional MRI brain state occupancy in the presence of cerebral small vessel disease -- pre-registration for a replication analysis of the Hamburg City Health Study
Testing the replicability of dynamic functional connectivity correlates of cerebral small vessel disease in the Hamburg City Health Study
Recommended by Robert McIntosh based on reviews by Olivia Hamilton and 1 anonymous reviewerA recent study has reported that the extent of cerebral small vessel disease (cSVD) shows associations with dynamic functional connectivity measures obtained from resting state functional MRI scans (Schlemm et al, 2022). Specifically, when the functional scan was parsed into time spent in discrete brain states, the proportion of time spent in the two most-occupied states was negatively related to a structural indicator of cSVD (volume of white matter hyperintensities of presumed vascular origin). This measure of 'fractional occupancy' was also associated with cognitive impairment as indicated by longer time to complete part B of the Trail Making Test. These findings were based on the analysis of data from 988 participants in the Hamburg City Health Study (HCHS).
In the present Registered Report, Schlemm (2023) will test whether these associations can be replicated in an independent sample of participants from the HCHS, not included in the earlier analysis (projected N for new analysis ~1500). In addition to the two main hypothesis tests, an exploratory multiverse analysis will be reported, systematically varying some key parameters of the MRI processing pipeline to provide further information about the robustness of the outcome of the primary hypothesis test.
The Stage 1 plan was refined over two rounds of review by two relevant experts, with additional input from the recommender on the specification of the registered plan. Both reviewers are satisfied that the plan constitutes an appropriate approach to this question, and on the basis of their comments and his own evaluation, the recommender judged that the Stage 1 report meets the criteria for in-principle acceptance.

Replicating the facilitatory effects of transcranial random noise stimulation on motion processing: A registered report
Testing the facilitatory effect of high-frequency transcranial random noise stimulation through enhancement of global motion processing
Recommended by Robert McIntosh based on reviews by Sam Westwood and Filippo GhinHigh 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).

Minimal mindfulness of the world as an active control for a full mindfulness of mental states intervention: A Registered Report and Pilot study
Testing the metacognitive basis and benefits of mindfulness training
Recommended by Robert McIntosh based on reviews by Chris Noone and Julieta GalanteMindfulness 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).

Causal evidence for the role of the sensory visual cortex in visual short-term memory maintenance
Can the visual cortex maintain information in the short term?
Recommended by Zoltan Dienes based on reviews by Robert McIntosh, Evie Vergauwe and Vincent van de VenAccording to the sensory recruitment framework, the visual cortex is at least in part responsible for maintaining information about elementary visual features in visual short term memory. Could an early visual area, constantly taking in new information, really be responsible for holding information for up to a second? But conversely, could higher order regions, such as frontal regions, really hold subtle sensory distinctions? It must be done somewhere. Yet the existing evidence is conflicting. Phylactou et al. seek to address this question by applying transcranial magnetic stimulation (TMS) to disrupt early visual areas at intervals up to a second after stimulus presentation to determine the effect on visual short term memory performance. In this way they will causally influence the sensory cortex at relevant times while tightening up on possible confounds in earlier research.
The Stage 1 manuscript was evaluated over two rounds of in-depth review by three expert reviewers. 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).
