STAGE 1
How Intelligence Interviewees Mentally Identify Relevant InformationHow an interviewee knows what information is key to disclose or withholdRecommended by Zoltan Dienes based on reviews by 2 anonymous reviewers
Research on interviewing has often focused on topics (such as aiding memory of witnesses) which presume the interviewee has already correctly identified the precise information that the interviewer is really after. But how does an informant know what sort of information is asked for, a precondition for an informant to then choose to provide the information or withhold it (depending on their own interests)?
In this study, Neequaye and Lorson will ask subjects to take the role of an informant about a criminal gang, with the further instructions to be cooperative or resistant in helping the interviewer obtain the information they want. In one study, the participants will be asked merely to identify what information the interviewer wants. In the second study, the participants will answer the interviewer's questions, disclosing whatever information they feel best suits their interest. Crucially, the level of detail of the questions will be manipulated, such that the question specifies a clear objective or not. The Stage 1 manuscript was evaluated over three rounds of in-depth review. Based on detailed responses to the reviewers’ comments and edits to the stage 1 report, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).

Exploring How Members of Illicit Networks Navigate Investigative InterviewsWhat to say to help one's partners in crimeRecommended by Zoltan Dienes based on reviews by Lorraine Hope
When interviewing members of a criminal network, what determines the information a given interviewee chooses to disclose, as guided by the network's collective planning? What principles could help inform a detective preparing for such interviews? In the current study, Neequaye et al. recruited groups of people known to each other to assume the role of networks that run an illegal sports betting business, fronting as a chain of tanning salons. Although each network launders money, they have to come up with a strategy to convince investigators they are legit. The groups are motivated to disclose some information when individuals are interviewed, but only enough to appear cooperative. Members disclosed information they perceived would yield benefical outcomes, but the extent to which members disclosed varied substantially according to the groups they were in.
The Stage 2 manuscript was evaluated over one round of in-depth review. Based on detailed responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

Breaking Ban: Belgium’s ineffective gambling law regulation of video game loot boxesLoot boxes remain prevalent in Belgium despite their “ban”Recommended by Veli-Matti Karhulahti based on reviews by Andrew Moshirnia, Joseph Macey and Jason Chin
Several countries currently struggle to legally interpret and deal with loot boxes, i.e. gambling-like mechanisms that have become common especially in contemporary videogame design. One of the few countries to take a clear regulation stance is Belgium, which officially announced that they interpret paid loot boxes as games of chance that violate their Gaming and Betting Act and can thus be criminally prosecuted (Naessens 2018). This announcement four years ago laid the basis for a unique social experiment where companies offering loot boxes in Belgium had to decide whether to modify their games, exit the market, or continue to monetize with loot boxes. In the present study, Xiao (2022) investigated the outcomes of this experiment both via hypotheses testing and exploratory analysis.
Using the 100 highest-grossing iPhone games in Belgium as data and applying comprehensive qualitative mechanical analysis to each title, Xiao (2022) tested three preregistered hypotheses regarding loot box prevalence. None of the hypotheses were confirmed: the prevalence rate of loot boxes in the Belgian App Store was not null but extremely high (82.0%), also among mobile games designed for minors (54.2–80.2%), and significantly more compared to global standards when assessed by a binomial test (p<.001). Corroborating a fourth hypothesis, Xiao was also able to access various UK loot boxes in Belgium. In exploratory research, Xiao received a confirmation from the Belgian Gaming Commission that even “simulated gambling games” (that do not yield monetary wins) also legally constitute gambling in Belgium.
The results are the first to describe outcomes of ban-driven loot box regulation globally. Despite Belgium’s clear statement that “paid loot boxes must be removed from the video games in order to comply with the Belgian Gaming and Betting Act” (Naessens 2018, p. 16), almost all highest-grossing iPhone games in the Belgian App Store keep offering them. The finding is important especially for the legal authorities around the world who are currently assessing their own positions in potential regulation: simple statements are unlikely to have immediate effects on international companies in local markets. On the other hand, it remains unknown how these companies have interpreted the statement and what are their distinct reasons for continuing to offer loot boxes in the Belgian App Store. It would be important in future research to investigate the companies’ perspectives.
This study (Xiao 2022) is important also from a meta-scientific perspective. It paves the way for Registered Reports in new disciplines and methods, and involves an exceptional field experiment that was carefully documented with open data and materials. Three external experts reviewed the Stage 2 manuscript twice, based on which the recommender awarded a positive recommendation.

STAGE 1
Beneath the label: Assessing video games’ compliance with ESRB and PEGI loot box warning label industry self-regulationHow effective is self-regulation in loot box labelling?Recommended by Chris Chambers based on reviews by Pete Etchells and Jim Sauer
Paid loot boxes – items bought for real-world money that offer randomised rewards – are a prevalent feature of contemporary video games (Zendle et al., 2020). Because they employ random chance to provide rewards after spending real money, loot boxes have been considered a form of gambling, raising concerns about risk of harm to children and other vulnerable users. In response, some countries have taken legal steps to regulate and even ban the use of loot boxes, with only limited success so far (Xiao, 2022). At the same time, the Entertainment Software Rating Board (ESRB) and PEGI (Pan-European Game Information) now expect games that contain loot boxes to be marked with warning labels that, in theory, will enable users (including parents) to make more informed decisions. These requirements by ESRB/PEGI are not legally binding and may be considered a form of industry self-regulation.
In the current study, Xiao (2023) will investigate the effectiveness of self-regulation in the use of loot box labels. Study 1 examines the consistency of warning labels by the ESRB and PEGI, with the expectation that if self-regulation works as it should then these labels should always (or nearly always) co-occur. Study 2 establishes the compliance rate for labelling among popular games that are known to contain loot boxes, with a rate of ≥95% considered to be successful. The findings should prove useful in identifying the success or failure of self-regulation as a means of ensuring industry compliance with loot box labelling.
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).

STAGE 1
Does Brooding Meaningfully Increase the Likelihood of Believing in a Conspiracy? A Registered ReportDoes brooding increase conspiracy beliefs?Recommended by Chris Chambers based on reviews by Matt Williams and 1 anonymous reviewer
The world is seemingly awash with conspiracy theories – from well-trodden examples such as fake Moon landings, the 9/11 truth movement, and Holocaust denial, to relative newcomers including COVID as a bioweapon, QAnon, and the belief that the science of climate change has been invented or falsified. While there is a public perception that conspiracy theories are becoming more prevalent, recent evidence suggests that the rate of conspiracism is relatively stable over time (Uscinski et al., 2022). At any point in history, it seems that a certain proportion of people find themselves vulnerable to conspiracy beliefs, but what distinguishes those who do from those who don’t, and what are the causal factors?
In the current study, Liekefett et al. (2023) investigate the critical role of rumination – a perseverative and repetitive focus on negative content leading to emotional distress. In particular, the authors ask whether one component of rumination referred to as brooding (dwelling on one’s worries and distressing emotions) has a specific causal role in the formation of conspiracy beliefs. In a series of preliminary experiments, the authors first established a procedure for successfully inducing rumination, identifying various boundary conditions and requirements for a successful design. In the proposed study (of up to N=1,638), they will then ask whether the induction of brooding causes a significant increase in conspiracy beliefs. Manipulation checks will be included to confirm intervention fidelity (independently of this hypothesis), and exploratory analyses will test the effect of various moderators, as well as the causal role of a complementary manipulation of reflection – a component of rumination in which attention is focused on the issue at hand rather than one’s emotions.

Beneath the label: Unsatisfactory compliance with ESRB, PEGI, and IARC industry self-regulation requiring loot box presence warning labels by video game companiesFailure of industry self-regulation in loot box labellingRecommended by Chris Chambers

Study 2 established the compliance rate for labelling among popular games that are known to contain loot boxes, with a rate of ≥95% considered to be successful.
The results of both studies reveal deficiences in industry self-regulation. The consistency rate of warning labels by the ESRB and PEGI was just 39.4% in preregistered analyses, rising to 83.9% in an unregistered exploratory analysis that took into account industry responses to the findings. Even at this upper bound, this rate is lower than expected by complete (or near-complete) consistency. The results of Study 2 indicate that only 29% of games on the Google Play Store known to contain loot boxes were accurately labelled, indicating that 71% were non-compliant with industry requirements.
Following careful evaluation, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

STAGE 1
Does retrieval practice protect memory against stress? A meta-analysis [Stage 1 Registered Report]Can retrieval practice prevent the negative impact of acute stress on memory performance?Recommended by Thomas Evans based on reviews by Chris Hartgerink (they/them) and Adrien Fillon
There are a number of broad assumptions about memory which have penetrated societal understanding and mostly reflect supporting academic evidence e.g., that acute stress can compromise memory performance (Shields et al., 2017) and that practicing recalling critical information can help retain that knowledge (Moriera et al., 2019). The evidence base is less consistent when evaluating whether retrieval practice can protect against the negative effects of acute stress on memory, despite it being highly important for educators as to whether this specific strategy for supporting memorisation can be evidenced as especially effective under stressful conditions. A rigorous review of this mixed evidence base could provide the basis for developments in memory theory and research practice, with potential for direct educational applications.
Meta-analyses can play a critical role in furthering our understanding of complex cognitive mechanisms where the evidence base includes a wide range of methods, factors and effect size estimates. Furthermore, there is a lack of rigorous meta-analyses that prioritise open and reproducible processes (Topor et al., 2022) which help role-model good practice. In the current Registered Report, Mihaylova et al. (2024) have proposed a rigorous meta-analysis to systematically review and synthesise the evidence on the effects of retrieval practice for memory performance under acute stress. The work looks to be especially valuable for a) informing future research directions through a structured risk of bias evaluation, and b) generating theoretical developments through a range of confirmatory moderators (including stressor types, memory strategies, time of delay and task type). The findings of the planned analyses are expected to be of immediate interest to educational and occupational domains where memory recall is a priority.

Cross-cultural relationships between music, emotion, and visual imagery: A comparative study of Iran, Canada, and Japan [Stage 1 Registered Report]Testing cross-cultural difference in the emotionality and visual associations of musicRecommended by D. Samuel Schwarzkopf based on reviews by Elena Karakashevska, Juan David Leongómez and Nadine Dijkstra
For many of us, music is far more than an auditory experience. It can trigger emotional reactions, evoke memories, and wide-ranging associations with other sensory modalities and cognitive states. Music also varies between different cultures in several ways. It remains unclear in how far the broader associations music has differs between cultural contexts, both in terms of the music itself and the listener. This study by Hadavi et al. (2024) seeks to better understand these relationships. Using an online survey targeted at 72 participants from anglophone Canada, Farsi-speaking Iran, and Japan (24 from each location), the researchers aim to address two straightforward hypotheses.
First, does faster tempo of music increase ratings of emotional arousal? Second, do participants match faster tempo music with denser visual line patterns? This latter measure aims to quantify the visual imagery evoked by the musical pieces. Imagery is a loaded term that is not used consistently across the cognitive neuroscience literature; one could argue that what the researchers are actually here is in fact mainly an association between tempo and a visual representation of tempo (or frequency). It certainly seems doubtful that persons listening to a piece of music will form a mental image of a bundle of horizontal lines. Yet, irrespective of how to interpret this experimental variable, it quantifies something about the impression listeners have when experiencing music, and whether these associations differ cross-culturally. The experiment has a balanced design, incorporating excerpts of musical pieces from each of the three cultural contexts, including both solo and group music. While the sample size is comparably low, given the online nature of data collection, it is based on a power analysis and relatively large expected effect sizes.
The proposed study was evaluated by three expert reviewers and the recommender over three rounds of in-depth review, plus a final round ironing out smaller issues. Reviewer Juan David Leongómez was recruited as a co-author after the first round of revisions. Following this process, the recommender decided that the manuscript met Stage 1 criteria and awarded in-principle acceptance (IPA).

Investigating individual differences in linguistic statistical learning and their relation to rhythmic and cognitive abilities: A speech segmentation experiment with online neural trackingIndividual differences in linguistic statistical learning and the relationship to rhythm perceptionRecommended by Elizabeth Wonnacott based on reviews by 2 anonymous reviewers
Previous research has demonstrated that experimental participants – both adults and infants – can track syllable co-occurrences in an artificial speech stream. This statistical learning (SL) is thought to support word segmentation and to be a core component of language acquisition. There is also some evidence that SL, as measured through artificial language tasks, is related to individual differences in language learning. What is not well understood is the underpinnings of individual differences in SL. In the current study, van der Wulp et al. (2023) will investigate the relationship between auditory SL and musical – specifically rhythmic – abilities. This work takes advantage of recent methodological innovations which allow online assessment of SL via electroencephalography (EEG) measures of neural entrainment. Up to N=105 participants will be recruited (using a well specified optional stopping procedure) and will be exposed to an artificial language using this EEG method to measure their response to the language through the exposure phase. In addition, post-tests will assess participants’ learning of the artificial language using behavioural tasks, as well as their abilities in a battery of tasks measuring rhythmic, musical, and cognitive abilities, and their vocabulary size. Core analyses will investigate whether the neural signature of statistical learning is found at a group level (i.e. replicating previous work) and whether at the individual level this is related to rhythm perception. Bayes factors will be used to assess the extent of evidence for these hypothesized relationships over the null. Exploratory analyses will explore other relationships, including with working memory and vocabulary size.
The topic of individual differences in language learning and is important, but work in this area is often underpowered, and the correlational nature of the research makes it vulnerable to HARKing. In this context, the current RR looks set to make an important contribution. The Stage 1 manuscript was evaluated over two rounds of in-depth review by the recommender and two expert reviewers, and one additional round of review by the recommender, before issuing in-principle acceptance.

Globally, songs and instrumental melodies are slower, higher, and use more stable pitches than speech [Stage 2 Registered Report]Strong evidence for cross-cultural regularities in music and speechRecommended by Chris Chambers based on reviews by Bob Slevc and Nai Ding
For centuries, the ubiquity of language and music across human societies has prompted scholars to speculate about their cross-cultural origins as well as their shared and unique characteristics. Depending on the extent to which contemporary theories emphasise the role of biology vs. culture, a range of hypotheses have been proposed concerning expected similarities and differences in song and speech. One class of hypotheses stemming from cultural relativism assumes a lack of universal regularities in song and speech, and therefore predicts no systematic cross-cultural relationships. On the other hand, more recent evolutionary hypotheses such as the social bonding hypothesis, motor constraint hypothesis, and sexual selection hypothesis all predict differences or similarities in specific characteristic of vocalisations, such as pitch regularity, pitch interval size, and melodic contour. Existing results are mixed in their support of these predictions.
In the current study, Ozaki et al. (2023) elucidated cross-cultural similarities and differences between speech and song in 75 different linguistic varieties spanning 21 language families. Understanding precisely how song and speech are related is methodologically challenging due to the multitude of confounds that can arise in comparing natural recordings. Here the authors overcame these difficulties with four types of carefully controlled recordings: singing, recitation of sung lyrics, spoken description of the song, and instrumental version of the sung melody. The authors then examined six features that are amenable to reliable comparison, including pitch height, temporal rate, pitch stability, timbral brightness, pitch interval size, and pitch declination. With this data in hand, the authors asked which acoustic features differ reliably between song and speech across cultures, with the expectation that song would exhibit higher pitch, slower rate and more stable pitch than speech. At the same time, the authors expected song and speech to be reliably similar in the characteristics of timbral brightness, pitch intervals and pitch contours
The findings provided strong support for the preregistered hypotheses. Relative to speech, songs exhibited higher pitch, slower temporal rate, and more stable pitches, while both songs and speech had similar pitch interval size and timbral brightness. Only one hypothesis was unsupported, with the comparison of pitch declination between song and speech turning out inconclusive. To overcome potential sources of analytic bias, the authors undertook additional robustness checks, including reanalysis of a previously published dataset of over 400 song/speech recordings; this exploratory analysis corroborated the conclusions from the confirmatory analysis. Overall this study offers a unique insight into the shared global characteristics of langage and music, with implications for understanding their cultural and biological (co)evolution.
The Stage 2 manuscript was evaluated over one round of in-depth review. Based on responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 2 criteria and therefore awarded a positive recommendation.

Level of bias control achieved: Level 2. At least some data/evidence that was used to answer the research question had been accessed and partially observed by the authors, but the authors certify that they had not yet observed the key variables within the data that were be used to answer the research question AND they took additional steps to maximise bias control and rigour.
