Revisiting Partition Priming in judgment under uncertainty: Replication and extension Registered Report of Fox and Rottenstreich (2003)Understanding probability assessments with partitioned framingRecommended by Romain Espinosa based on reviews by Olivier L'Haridon and Don Moore
Decision-making based on limited information is a common occurrence. Whether it is the possibility of a cheaper product elsewhere or the unknown qualifications of election candidates, people are regularly forced to make a decision under ignorance or uncertainty. In such situations, information about certain events is unavailable or too costly to acquire and people rely on subjective probability allocation to guide decision-making processes. This allocation seems to result in what is known as ignorance priors, i.e., decision-makers assigning equal probabilities to each possible outcome within a given set. How events are grouped or partitioned is often subjective and may influence probability judgments and subsequent decisions. In such cases, the way the choices within a choice set are presented may shape the perceived likelihood of different outcomes. Understanding the impact of partitioning on probability estimation is crucial for both psychological and economic theories of judgment and decision-making. In the current work, Ding and Feldman (2025) conducted a replication study of one of the foundational works on the topic: Fox and Rottenstreich (2003). In the original work, the authors provided exploratory evidence indicating that the framing of a situation affects the way individuals perceive probabilities of possible outcomes. They showed that people assigned uniform probabilities to sets of events described in a problem, such that the way the events are described partly determined people’s partitioning of those events and evaluations of the probabilities of the possible outcomes. Additionally, this partitioned framing affected judgments both under conditions of ignorance (where individuals have no information and rely solely on uniform probability assignments) and uncertainty (where individuals have some information but still rely on heuristics influenced by partitioning). This suggests that priors resulting from the inference of available evidence are sometimes partly contaminated by partitioning bias, affecting both uninformed and partially informed decision-making processes. As a consequence, the partitioning of events into different subsets might lead to varying evaluations of a single situation, resulting in inconsistencies and poorly calibrated probability assessments. Ding and Feldman (2025) conducted a replication work on Studies 1a, 1b, 3, and 4 from Fox and Rottenstreich (2003). Their close replication relies on original data (US participants, Prolific, N=603) with a large statistical power (>95%). The replication aimed to assess whether the partitioned framing affects prior formation under ignorance (Studies 1a, 1b, and 4) and uncertainty (Study 3). The authors also proposed an extension examining estimations of complementary events contrasting estimations of the probabilities of the events happening versus the probabilities of the events not happening. Overall, the authors successfully replicated the original study based on their pre-registered evaluation criteria, finding support for partition dependence for most scenarios under scrutiny, yet with weaker effect sizes than the original studies. Out of the eleven Cohen’s h estimated by the replication study, one is consistent with the original study’s estimate (i.e., the original point estimate lies within the confidence interval of the replication), seven go in the same direction but are smaller (i.e., same sign for the estimated effect but the original point estimate is outside the CI of the replication), and two are not statistically different from zero (i.e., the CI of the replication includes zero). This Stage 2 manuscript was evaluated over one round of in-depth review by two expert reviewers and a second round of review by the recommender. After the revisions, the recommender judged that the manuscript met the Stage 2 criteria and therefore awarded a positive recommendation.

Can adults automatically process and translate between numerical representations?The role of working memory in translating between different number processing systemsRecommended by Zoltan Dienes based on reviews by Hannah Dorothea Loenneker and Xinru Yao
People can represent quantities in different ways. Numbers can be represented non-symbolically through an Object Tracking System (for small quantities, when one immediately perceives how many objects are there) and an Approximate Number System (for large quantities), and symbolically, for example with Arabic symbols or words. One unresolved question is the extent to which using these numerical representations, and transferring between them, can be done automatically, or rather involves components of working memory. Key relevant working memory components are the phonological loop and the visuospatial sketchpad.
In this study, Xenidou-Dervou and colleagues (2025) asked subjects to perform a dot comparison task with small and large numbers, to engage the non-symbolic systems, and a digit comparison task, to engage the symbolic system, and a cross modal task to engage translation between the systems. Participants either performed these tasks alone or with a secondary task, one that loaded either the phonological loop or else the visuospatial sketchpad. In the comparison of symbolic numerals, the visual secondary task itself was performed more poorly in dual rather than single task conditions, indicating the involvement of the visual spatial sketchpad in use of symbolic numerals. The visual secondary task interfered with non-symbolic number judgements, indicating involvement of the visuospatial sketch pad with the non-symbolic system as well. Finally, the translation between the systems also involved the visuospatial sketchpad, as shown by the secondary task itself suffering dual task interference. In sum, there was evidence for the visuospatial sketchpad, but not for the phonological loop, playing a role in simple comparisons using either or both of the symbolic and non-symbolic number systems. The Stage 2 manuscript was evaluated over two rounds of in-depth review. Based on detailed responses to the reviewers’ comments and edits to the Stage 2 report, the recommender judged that the manuscript met the Stage 2 criteria for recommendation.

Can adults automatically process and translate between numerical representations?The role of working memory in translating between different number processing systemsRecommended by Zoltan Dienes based on reviews by Hannah Dorothea Loenneker and Lincoln Colling
People can represent quantities in different ways. Numbers can be represented non-symbolically through an Object Tracking System (for small quantities, when one immediately perceives how many objects are there) and an Approximate Number System (for large quantities), and symbolically, for example with Arabic symbols or words. One unresolved question is the extent to which using these numerical representations, and transferring between them, can be done automatically, or rather involves components of working memory. Key relevant working memory components are the phonological loop and the visuospatial sketchpad.
In this study, Xenidou-Dervou and colleagues (2022) will ask subjects to perform a dot comparison task with small and large numbers, to engage the non-symbolic systems, and a digit comparison task, to engage the symbolic system, and a cross modal task to engage translation between the systems. Participants will either perform these tasks alone or with a secondary task, one that loads either the phonological loop or else the visuospatial sketchpad. The extent of interference of the secondary task on the primary tasks will indicate the involvement of the corresponding working memory component with using and translating numerical representations which are either symbolic or non-symbolic. The results may thus shed light on the ways in which people can deal with numbers successfully – or fail to do so.

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.

Revisiting the Effects of Helper Intention on Gratitude and Indebtedness: Replication and extensions Registered Report of Tsang (2006)Grateful or indebted? Revisiting the role of helper intention in gratitude and indebtednessRecommended by Zhang Chen based on reviews by Jo-Ann Tsang, Sarahanne Miranda Field and Cong Peng
When receiving a favor, we may feel grateful and/or indebted to those who have helped us. What factors determine the extent of gratitude and indebtedness people experience? In a seminal paper, Tsang (2006) found that people reported feeling more gratitude when the helper's intention was perceived to be benevolent rather than selfish. In contrast, indebtedness was not influenced by the perceived intention of the helper.
In the current study, Chan et al. (2025) revisited the effects of helper intention on gratitude and indebtedness, by replicating and extending the original studies (Study 2 & 3) by Tsang (2006). Participants were asked to either recall (replication of Study 2) or read (replication of Study 3) a scenario in which another person helped them with either benevolent or selfish intentions, and rate how much gratitude and indebtedness they would experience in such situations. Replicating the findings by Tsang (2006), Chan et al. (2025) found that gratitude was more strongly influenced by helper intention than indebtedness. Extending these findings, the authors further discovered that helper intention affected perceived expectations for reciprocity and reciprocity inclination. Moreover, perceived reciprocity expectations showed opposite correlations with gratitude and indebtedness. Overall, this successful replication reinforces the distinction between gratitude and indebtedness, providing a solid foundation for future research on their underlying mechanisms and downstream influences. This Stage 2 manuscript was evaluated over one round of in-depth review by three expert reviewers, and a second round of review by the recommender. After the revisions, the recommender judged that the manuscript met the Stage 2 criteria and therefore awarded a positive recommendation.

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).

Sensorimotor Effects in Surprise Word Memory – a Registered ReportEvaluating adaptive and attentional accounts of sensorimotor effects in word recognition memoryRecommended by Clara Cohen and Chris Chambers based on reviews by Gordon Feld
Words have served as stimuli in memory experiments for over a century. What makes some words stand out in memory compared to others? One plausible answer is that semantically rich words are more distinctive and therefore exhibit a mirror effect in recognition memory experiments where they are likely to be correctly endorsed and also less likely to be confused with other words (Glanzer & Adams, 1985). Semantic richness can arise due to extensive prior experience with the word in multiple contexts but can also arise due to sensorimotor grounding, i.e., direct perceptual and action-based experience with the concepts represented by the words (e.g. pillow, cuddle). However, previous experiments have revealed inconsistent recognition memory performance patterns for words based on different types of sensorimotor grounding (Dymarska et al., 2023). Most surprisingly, body-related words such as 'cuddle' and 'fitness' exhibited greater false alarm rates.
In the current study, Dymarska and Connell (2025) tested two competing theories that can explain the increased confusability of body-related words: 1) the adaptive account - contextual elaboration-based strategies activate other concepts related to body and survival, increasing confusability; and 2) the attentional account - somatic attentional mechanisms automatically induce similar tactile and interoceptive experiences upon seeing body-related words leading to less distinctive memory traces. The adaptive account leads to different predictions under intentional and incidental memory conditions. Specifically, contextual elaboration strategies are unlikely to be employed when participants do not expect a memory test and therefore in an incidental memory task, body-related words should not lead to inflated false alarm rates (see Hintzman (2011) for a discussion on incidental memory tasks and the importance of how material is processed during memory tasks). However, the attentional account is not dependent on the task instructions or the knowledge about an upcoming memory test. Here, Dymarska and Connell (2025) undertook an incidental recognition memory experiment with over 5000 words, disguised as a lexical decision task using carefully matched pseudowords during the encoding phase. The sample size was determined by using a sequential hypothesis testing plan with Bayes Factors. To test the predictions of the adaptive and attentional accounts, the authors derived a set of lexical and sensorimotor variables (including a body-component) after dimensionality reduction of a comprehensive set of lexical and semantic word features. The analysis involved running both Bayesian and frequentist hierarchical linear regression to explain four different measures of recognition memory performance based on the key sensorimotor variables and other baseline/confounding variables. While this analysis plan enables a comparison with the earlier results from an expected memory test (Dymarska et al., 2023), the current study is self-contained in that it is possible to distinguish the adaptive and attentional accounts based on the effect of body component scores on hit rate and false alarm rate. Results provided support for the attentional account: body-related words increased false alarms even when attention was not directed to them during the study phase, consistent with a somatic attentional mechanism that causes body-related words to activate tactile and other bodily modalities that render their representations less distinctive as a memory trace and retrieval cue. Overall, the authors conclude that their findings point to a reconsideration of the role of semantic richness in word memory.

On the neural substrates of mind wandering and dynamic thought: A drug and brain stimulation studyDoes dopamine availability influence the effect of brain stimulation on mind-wandering?Recommended by Maxine Sherman based on reviews by Chris Chambers and 1 anonymous reviewer
Mind-wandering broadly refers to the phenomenon by which a person's thoughts are directed towards internally generated states as opposed to being directed towards those that are task-relevant. It has been proposed that mind-wandering and cognitive control are supported by overlapping neural systems. While neuroimaging work has implicated prefrontal cortex in both mind-wandering and cognitive control, studies testing its causal role using transcranial direct current stimulation (tDCS) have been inconclusive.
Here, Rasmussen and colleagues (2025) put to a strict test the question of whether the effects of prefrontal cortex tDCS on mind-wandering are mediated by dopaminergic availablility, which is known to be important for cognitive control. Using noninvasive brain stimuluation (prefrontal cortex tDCS vs sham) and a pharmacological intervention (levodopa vs. placebo), they found that contrary to some previous work, stimulation of prefrontal cortex does not alter mind-wandering. By contrast, in the absence of stimulation, increasing dopamine availability via levodopa reduced the frequency of freely moving thought. Together, these results clarify the degree to which prefrontal cortex tDCS and dopamine play a causal role in mind-wandering

The role of extra-striate areas in conscious motor behavior: a registered report with Fast-Optical ImagingNeural underpinning of conscious perception of visual stimuli disentangled from motor confoundsRecommended by Anoushiravan Zahedi based on reviews by 3 anonymous reviewers
The debate about consciousness and its neural underpinnings is a hot topic in cognitive neuroscience that has driven innovative original research and theoretical frameworks (Dehaene et al., 2006; Lamme, 2006). Consciousness itself can be defined and studied from different perspectives, such as neuropsychology (Laureys et al., 2004; Monti, 2012), applied philosophy (Blanke & Metzinger, 2009), and experimental cognitive neuroscience (Dehaene & Changeux, 2011). However, after several decades of research via different methods and from different perspectives, basic questions regarding consciousness and its neural underpinnings are still debated (Chalmers, 2010). One of the reasons for this ongoing debate is that consciousness cannot be easily disentangled from confounds, such as involvement of other cognitive processes like memory, language, and so forth (Dehaene & Changeux, 2011).
In the current study, Colombari et al. (2025) focus on disentangling neural markers of conscious visual perception from motoric responses. To this end, the study uses a cutting-edge neuroimaging technique, Event-Related Optical Signal (EROS), to measure the neural responses during a Go/No-Go detection task, which is especially designed to gauge visual perception regardless of response production. The study, therefore, is instrumental in addressing the neural foundation of conscious visual perception and is well situated to advance our understanding of consciousness and its neural underpinnings.
The Stage 1 submission was evaluated by three expert reviewers. After several rounds of revision, the recommender determined that the manuscript met the Stage 1 criteria and awarded in-principle acceptance (IPA).
