STAGE 1
Is conscious perception necessary to direct attention? A replication of Jiang et al. (2006)Can sexually salient stimuli direct attention outside of conscious awareness?Recommended by Reshanne Reeder based on reviews by Myron Tsikandilakis and Surya Gayet
Are attention and consciousness inherently intertwined or distinct aspects of cognition? One report (Jiang et al. 2006) presented clear results in evidence of the latter. In this earlier study, the authors used a continuous flash suppression (CFS) paradigm which presents a colorful pattern to the dominant eye and stimuli of interest to the non-dominant eye; the colorful pattern masks the relevant stimulus from awareness. On each trial, the authors presented a sexually stimulating image and a scrambled image on different sides of a computer screen during CFS. They found that, even though participants were not consciously aware of the images, intact images that matched participants' sexual orientation could still capture attention.
Despite these seemingly clear results, the authors of the current Stage 1 manuscript pointed out that CFS studies are often not replicated, and the paper by Jiang et al. (2006) is no exception. Therefore, Chen et al. (2023) seek to replicate this study using a Bayesian (rather than NHST) analytic approach. This method will allow the authors to determine the strength of evidence for their hypotheses.
In this Stage 1 manuscript, Chen et al. present an introduction that motivates the replication, and a pilot study that replicated the procedure of Jiang et al. (2006) conducted with 21 participants. This led to a well-motivated statistical sampling plan and some small design changes for the main experiment, such as adding a staircasing procedure to remove potential performance ceiling effects, and using less extreme wording for stimulus attractiveness ratings. A clear study design template is presented, detailing the different hypotheses that will be tested, and what different outcomes would indicate.

STAGE 1
Synaesthesia as a Model for Assessing Individual Differences in Visual Perception and Memory PerformanceWhat can synaesthesia tell us about links between perception and memory?Recommended by Reshanne Reeder based on reviews by Janina Neufeld, David Brang and Tessa van Leeuwen
What is the relationship between perception and memory? Although these topics are typically investigated separately, there is evidence that these cognitive processes may be related: for example, individuals with synaesthesia may experience both enhancements in visual acuity and visual memory; and individuals with amnesia may also show deficits in visual perceptual processing. However, comprehensive evidence for the relationship between perception and different forms of memory (both short-term and long-term) is currently lacking.
In this Stage 1 manuscript, Whelan et al. (2024) seek to elucidate this relationship by investigating individual differences in perception and memory in a general population sample (i.e., in synaesthetes, non-synaesthetic relatives, and controls). There are two accounts that may explain enhanced perception and memory in synaesthesia: a ‘dual-coding’ account, which suggests that the extra perceptual information often experienced in synaesthesia (e.g., seeing colors for different letters of the alphabet) may contribute to encoding richer information in sensory memory; and an ‘enhanced processing’ account, which posits that enhanced perception and memory in synaesthesia may be due to genetic or environmental factors not directly related to synaesthetic experiences. In the former case, synaesthetes should perform more similarly to each other than to their non-synaesthetic relatives; in the latter case, non-synaesthetic relatives of synaesthetes should show similar perceptual and memory benefits. The current study should therefore find evidence in favor of one of these accounts over the other. In addition to this, the authors will generate multidimensional cognitive profiles of synaesthetes and their relatives, compared to non-synaethetes, including perception, memory, mental imagery and cognitive styles.

STAGE 1
How perceptual ability shapes memory: An investigation in healthy special populationsPutting the enhanced processing account of perception and memory to the testRecommended by Reshanne Reeder based on reviews by Ariel Kershner and Katherine Moore
The enhanced processing account suggests that domain-specific expertise enhances the processing of information in that domain, such as enhanced color perception in visual artists and grapheme-color synaesthetes. A previous study (Ovalle-Fresa et al., 2021) found support for this account in both synaesthetes and non-synaesthete color experts; however, to fully understand the domain specificity of enhanced processing, other domains of expertise should be investigated and compared against each other in a double dissociation.
In this Stage 1 manuscript, Sachdeva et al. (2024) will investigate whether an enhanced processing account can explain domain-specific expertise in groups of color experts (i.e., visual artists) / grapheme-color synaesthetes and spatial experts (i.e., architects) / sequence-space synaesthetes. The spatial domain was chosen to compare to color since color and spatial processing recruit two distinctive cortical visual pathways: the ventral and dorsal streams, respectively. If enhanced processing is domain specific, then color experts / grapheme-color synaesthetes should show selective perceptual and memory performance enhancements for color tasks but not spatial tasks; and vice versa for spatial experts and sequence-space synaesthetes. The authors of this planned study further propose that perceptual performance should predict memory performance in the domain of expertise only; and that synaesthetes and non-synaesthetes with the same domain of expertise should perform similarly to each other.
To address these hypotheses, four independent groups will be recruited: grapheme-color synaesthetes, visual artists, sequence-space synaesthetes, and architects. Individuals with overlapping expertise and synaesthesia (e.g., visual artists who also have grapheme-color synaesthesia) will be excluded. Perception, short-term memory, and long-term memory for color (3 tasks) and space (3 tasks) will be assessed in all groups, and the authors will compare groups (synaesthetes, non-synaesthetes), domains of expertise (color, space), and task feature (color, space) in 2x2x2 linear mixed models. For all models, the authors predict that a significant interaction between domain of expertise and task feature will provide evidence for the domain specificity of the enhanced processing account. Additional analyses concerning working memory load (one, three, or five items) in the short-term memory tasks, and testing day (one, two, or three days post-training) in the long-term memory tasks, will be conducted to more deeply explore potential performance enhancements related to domain-specific expertise. Although these analyses may potentially provide additional evidence in favor of the hypothesized direction of effects, any deviation from predicted may pose a challenge for the interpretation of results. Nevertheless, this planned study is methodologically rigorous, and comprehensive in its aims.

STAGE 1
Representativeness heuristic in intuitive predictions: Replication Registered Report of problems reviewed in Kahneman and Tversky (1973)The Representativeness Heuristic Revisited: Registered Replication Report of Kahneman and Tversky (1973)Recommended by Rima-Maria Rahal based on reviews by Peter Anthony White, Regis Kakinohana and Naseem Dillman-Hasso
Revisiting a true classic, this registered replication report addresses Kahneman and Tversky’s (1973) introduction of the representativeness heuristic. The heuristic refers to deviations of judgments from normative evaluations of the evidence when the stimulus fits to a prototype. For instance, when an individual is described by features stereotypically associated with a certain target group (e.g., a person who attends dance training several times a week and has a passion for singing and performing), likelihood judgments that the individual belongs to a target group (K-Pop artists) compared to a non-target group (e.g., accountants) are inflated.
The impact of the original research on the field is clearly immense and long-lasting. All the better that a systematic replication attempt is being undertaken in this registered report, which addresses studies 1 through 7 of Kahneman and Tversky’s classic 1973 paper. Chan and Feldman (2024) propose a well-powered online study, in which all studies from the original article are presented to participants within-subjects. The materials are carefully constructed and closely documented in the accompanying OSF project, where in-depth information on planned data analyses is supported with a simulated dataset. The Stage 1 manuscript was evaluated over three 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). URL to the preregistered Stage 1 protocol: https://osf.io/er2cq
Level of bias control achieved: Level 6. Data collection commenced during the later part of Stage 1 peer review; however, since no substantive changes to the design were made after this point, the risk of bias due to prior data observation remains zero and the manuscript therefore qualifies for Level 6.

Do pain and effort increase prosocial contributions?: Revisiting the Martyrdom Effect with a Replication and extensions Registered Report of Olivola and Shafir (2013)More pain, more prosocial? Assessing the Martyrdom EffectRecommended by Rima-Maria Rahal based on reviews by Vanessa Clemens and Liesbeth Mann
The Martyrdom Effect is a behavioral tendency in which individuals exhibit greater generosity when their acts of giving entail effort or self-sacrifice (Olivola & Shafir, 2013). Giving at a personal cost, in this mindset, is associated with ascribing and inferring more meaning and value to charitable giving or other forms of generosity than in instances where no particular pain or effort is required to enact prosocial behavior. Arguably, the Martyrdom Effect’s ability to boost prosocial behavior therefore departs from other theories of behavior change postulating that easy options to act prosocially could boost contributions (e.g., default effects in charitable giving, see Altmann et al., 2019; Goswami & Urminsky, 2016). Because they introduce complexity to the debate about encouraging prosocial behavior, three studies from Olivola and Shafir (2013) are now being addressed in this Registered Report by Cheng and Feldman (2024).
Combining these three studies in a high-powered within-subjects replication attempt, transparently communicating necessary deviations from the original design and carefully outlining the analysis strategy, the current study will offer insights into the robustness of prior findings on the role of effort and pain in determining donations. The Stage 1 manuscript was evaluated by two reviewers and the recommender.

Independent Comparative Evaluation of the Pupil Neon - A New Mobile Eye-trackerAssessing the Promise of Affordable, Mobile Eye-Tracking Devices: Evaluation of the Pupil NeonRecommended by Rima-Maria Rahal based on reviews by Lisa Spitzer and Benedikt Ehinger
Studying eye-gaze has long been employed as a central method for understanding attentional dynamics and cognitive processes in a variety of domains. The development of affordable, mobile eye-tracking devices, such as the Pupil Neon, promises new opportunities to extend this research beyond the contexts in which traditional eye-trackers have been available. But how good are such novel devices at detecting variables relevant for the study of eye movements and pupil dilations?
Foucher, Krug and Sauter (2024) propose an independent evaluation of the Pupil Neon eye-tracker using the Ehinger et al. (2019) test battery, comparing its performance with a traditional EyeLink 1000 Plus device. In an empirical study, participants will be asked to perform a wide variety of tasks while eye movements and pupil dilations are tracked using both devices. Results on the strengths and weaknesses, as well as potential use cases of the Pupil Neon will be informative for subsequent eye-tracking research.

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).

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).

The importance of consolidating perceptual experience and contextual knowledge in face recognitionHow does perceptual and contextual information influence the recognition of faces?Recommended by Robert McIntosh based on reviews by Lisa DeBruine and Haiyang Jin
When 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 -- pre-registration for a replication analysis of the Hamburg City Health StudyTesting the replicability of dynamic functional connectivity correlates of cerebral small vessel disease in the Hamburg City Health StudyRecommended by Robert McIntosh based on reviews by Olivia Hamilton and 1 anonymous reviewer
A 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.
