STAGE 1
Beneath the label: Assessing video games’ compliance with ESRB and PEGI loot box warning label industry self-regulationLeon Y. Xiao https://osf.io/u7ghb?view_only=60cb55c3c3c74f76a8e170fb498e2789How effective is self-regulation in loot box labelling?Recommended by Chris Chambers based on reviews by Pete Etchells and Jim SauerPaid 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).

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
Assessing compliance with UK loot box industry self-regulation on the Apple App Store: a 6-month longitudinal study on the implementation processLeon Y. Xiao https://osf.io/7xft9Does self regulation by gaming companies for the use of loot boxes work?Recommended by Zoltan Dienes based on reviews by Chris Chambers, Lukas J. Gunschera and Andy PrzybylskiVideo games may provide the option of spending real money in exchange for probabilistically receiving game-relevant rewards; in effect, encouraging potentially young teenagers to gamble. The industry has subscribed to a set of regulatory principles to cover the use of such "loot boxes", including 1) that they will prevent loot box purchasing by under 18s unless parental consent is given; 2) that they will make it initially clear that the game contains loot boxes; and 3) that they will clearly disclose the probabilities of receiving different rewards.
Can the industry effectively self regulate? Xiao (2024) will evaluate this important question by investigating the 100 top selling games on the Apple App Store and estimating the percentage compliance to these three regulatory principles at two time points 6 months apart.
The Stage 1 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 1 criteria and therefore awarded in-principle acceptance (IPA).

Self-Control beyond inhibition. German Translation and Quality Assessment of the Self-Control Strategy Scale (SCSS)Leopold H. O. Roth1, Julia Jankowski1, Georgia Clay1, Dominik Meindl1, Lisa-Marie Vogt1, Victoria Wagner1, Artemis Nordmann1, Loana Stenzel1, Olga Freiman1, Christopher Mlynski1, Veronika Job1; 1University of Vienna, Vienna, Austria https://osf.io/n2xsdStrategies for self control: German translation and evaluation of the Self Control Strategy ScaleRecommended by Zoltan Dienes based on reviews by Eleanor Miles, Kaitlyn Werner and Sebastian BürglerSelf-control has shown to be a trait related to beneficial outcomes, including health, academic achievement and relationship quality. It is mostly understood as the ability to surpress immediate urges in order to achieve long-term goals, such as not watching another episode and therefore reaching a healthy amount of sleep. An emerging perspective on self-control shows that there is broader variety in applied strategies, such as removing oneself from a tempting situation, or reminding oneself of one's long-term goal, or reinterpreting the temptation.
Katzir et al. (2021) developed a novel instrument, the Self-Control Strategy Scale, that measured the tendency to engage in eight such strategies. In the current study, Roth et al. (2023) propose to translate the scale into German and assess its psychometric properties. Further, they will determine which strategies are related to particular outcomes that may be beneficial; for example, amount of physical activity engaged in, how healthy the diet is, exam performance and life satisfaction.
The Stage 1 manuscript was evaluated over two rounds of in-depth review by the recommender and at least two expert reviewers, before issuing in-principle acceptance.

Katzir et al. (2021) developed a novel instrument, the Self-Control Strategy Scale, that measured the tendency to engage in eight such strategies. In the current study, Roth et al. (2024) translated the scale into German and assessed its psychometric properties: internal consistency and retest reliability were sufficient for six or seven of the eight subscales. Further, different strategies (subscales) were related to particular outcomes; at least one strategy was related to each outcome for 20 out of 23 outcomes in health behavior, school/work achievement, life satisfaction, interpersonal functioning and pro-environmental behavior (though the particular pattern of similarities and differences would need confirming). Thus, the SCSS is a valid and reliable measure that can now be used in German.

One and only SNARC? Spatial-Numerical Associations are not fully flexible and depend on both relative and absolute magnitudeLilly Roth, John Caffier, Ulf-Dietrich Reips, Hans-Christoph Nuerk, Annika Tave Overlander, Krzysztof Cipora https://osf.io/ajqpkA Registered Report demonstration that the SNARC effect depends on absolute as well as relative number magnitudeRecommended 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.

One and only SNARC? A Registered Report on the SNARC Effect’s Range DependencyLilly Roth, John Caffier, Ulf-Dietrich Reips, Hans-Christoph Nuerk, Krzysztof Cipora https://osf.io/gr94fIs 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).

Convenience Samples and Measurement Equivalence in Replication ResearchLindsay J. Alley, Jordan Axt, Jessica Kay Flake https://osf.io/32unbDoes data from students and crowdsourced online platforms measure the same thing? Determining the external validity of combining data from these two types of subjectsRecommended by Corina Logan based on reviews by Benjamin Farrar and Shinichi NakagawaComparative research is how evidence is generated to support or refute broad hypotheses (e.g., Pagel 1999). However, the foundations of such research must be solid if one is to arrive at the correct conclusions. Determining the external validity (the generalizability across situations/individuals/populations) of the building blocks of comparative data sets allows one to place appropriate caveats around the robustness of their conclusions (Steckler & McLeroy 2008).
In this registered report, Alley and colleagues plan to tackle the external validity of comparative research that relies on subjects who are either university students or participating in experiments via an online platform (Alley et al. 2023). They will determine whether data from these two types of subjects have measurement equivalence - whether the same trait is measured in the same way across groups. Although they use data from studies involved in the Many Labs replication project to evaluate this question, their results will be of crucial importance to other comparative researchers whose data are generated from these two sources (students and online crowdsourcing). If Alley and colleagues show that these two types of subjects have measurement equivalence, then this indicates that it is more likely that equivalence could hold for other studies relying on these type of subjects as well. If measurement equivalence is not found, then it is a warning to others to evaluate their experimental design to improve validity. In either case, it gives researchers a way to test measurement equivalence for themselves because the code is well annotated and openly available for others to use.
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). Level of bias control achieved: Level 2. At least some data/evidence that will be used to answer the research question has been accessed and partially observed by the authors, but the authors certify that they have not yet observed the key variables within the data that will be used to answer the research question AND they have taken additional steps to maximise bias control and rigour (e.g. conservative statistical threshold; recruitment of a blinded analyst; robustness testing, multiverse/specification analysis, or other approach)

Restriction of researcher degrees of freedom through the Psychological Research Preregistration-Quantitative (PRP-QUANT) TemplateLisa Spitzer & Stefanie Mueller https://doi.org/10.23668/psycharchives.14119Examining the restrictiveness of the PRP-QUANT TemplateRecommended by Daniel Lakens based on reviews by Marjan Bakker and 1 anonymous reviewerThe Psychological Research Preregistration-Quantitative Template has been created in 2022 to provide more structure and detail to preregistrations. The goal of the current study is to test if the PRP-QUANT template indeed provides greater restriction of the flexibility in a study for preregistered hypotheses than other existing templates. This question is important because one concern that has been raised about the practice of preregistration is that the quality of preregistrations is often low. Metascientific research has shown that preregistrations are often of low quality (Bakker et al., 2020), and hypothesis tests from preregistrations are still selectively reported (van den Akker, van Assen, Enting, et al., 2023). It is important to improve the quality of preregistrations, and if a better template can help, it is a cost-effective approach to improve quality if the wider adoption of the better template can be promoted.
In the current study, Spitzer and Mueller (2024) will follow the procedure of a previous meta-scientific study by Heirene et al. (2021). 74 existing preregistrations with the PRP-QUANT template are available, and will be compared with an existing dataset coded by Bakker and colleagues (2020). The sample size is limited, but allows detecting some differences that would be considered large enough to matter, even though there might be smaller differences that would not be detectable based on the currently available sample size. Nevertheless, given that there is a need for improvement, even preliminary data might already be useful to provide tentative recommendations. Restrictiveness will be coded in 23 items, and adherence to or deviations from the preregistration are coded as well. As such deviations are common, the question whether this template reduced the likelihood of deviations is important. Two coders will code all studies.
The study should provide a useful initial evaluation of the PRP-QUANT template, and has the potential to have practical implications if the PRP-QUANT template shows clear benefits. Both authors have declared COI's related to the PRP-QUANT template, making the Registered Report format a fitting approach to prevent confirmation bias from influencing the reported results.
This Stage 1 manuscript was evaluated over two rounds of in-depth review by two expert reviewers and the recommender. After the revisions, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).
