While cerebral lateralisation for oral language is well-characterised, cerebral lateralisation for written language is much less well-understood. In this study, Papadopoulou et al. (2022) will use functional transcranial Doppler ultrasonography to assess lateralisation for written language in 7- to 9-year-old children at risk for dyslexia and neurotypical children. They will use tasks that assess efficiency in reading and writing names as well as speed and fluency in writing. The findings of this manuscript will highlight whether children with dyslexia showed atypical lateralisation for language in a written task. In addition, the authors plan to explore the correlation between lateralisation and writing competence. 

 

The Stage 1 manuscript was evaluated over two rounds of in-depth review. Based on the edits made to the manuscript, and detailed responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).

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.

Paid loot boxes, i.e. randomised monetization methods that are similar to lottery-type gambling, have become prominent features of contemporary gaming (e.g., Macey & Bujić, 2022). Because the design structures of loot boxes vary and the value of their virtual rewards is not always clear-cut, many countries now struggle how to deal with them legally and in practice (see Drummond et al., 2020). Belgium is one of the few countries that have officially interpreted loot box monetization to widely belong under gambling regulation. Mobile games that monetize with paid loot boxes in Belgium should thus apply for a gambling license, and companies should generally not offer paid loot boxes to local underage players at all.
 
In this Stage 1 Registered Report, Xiao (2022) has constructed a careful plan for testing whether the “ban” in Belgium has made the local mobile game market distinct in terms of paid loot boxes. The work builds on a rapidly accumulating literature and evolving methods (e.g., Xiao et al., 2021). The author will carry out a systematic qualitative investigation of the country’s top 100 (iPhone) mobile games to investigate whether paid loot box design components have indeed been removed from the products -- and if not, whether related game companies operate with a required gambling license. Additionally, Xiao (2022) will assess Belgium’s overall paid loot box prevalence in comparison to other countries and carry out a field experiment to test whether players can easily circumvent the local regulation by transporting or downloading different versions of software.
 
The study will produce valuable evidence regarding the effectiveness of loot box regulation in general, and more specifically, the results should be of utmost interest to Belgian legal authorities. To ensure the transparency and validity of the chosen methods as well as upcoming interpretations, the registered report format allowed the research design to be reviewed in three rounds before data collection. Three experts, representing the fields of law and gaming, reviewed the Stage 1 manuscript twice and agreed upon the acceptance of all details. Finally, the recommender carried out a third iteration with further requested revisions, which was followed by in-principle acceptance. 

 

Video 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).

Measurement is a vital activity for all research areas, but we so often fail to provide sufficient clarity, rigor and transparency about it, undermining the validity of our studies' conclusions (Flake & Fried, 2020). This concern is of wide societal interest when applied to the domains of ideology and attitudes where measurements of both implicit and explicit attitudes are assumed to reflect the same underlying concept. The extent to which this can be accepted is undermined by mixed evidence demonstrating a lack of consensus on the extent to which relevant psychological factors similarly predict both implicit and explicit attitudes.

 

In the current study, Reid & Inbar (2023) question these assumptions through use of the Project Implicit dataset, exploring the extent to which social dominance orientation (SDO) and right wing authoritarianism (RWA) similarly predict implicit and explicit attitudes. This work was ideally suited for publication through the Registered Reports format because whilst it may have been expected that relationships between SDO/RWA are similar in effect size across measures of both implicit and explicit attitude (because they tap into the same underlying attitude), there was great scope to acknowledge a more complex set of findings which may not be immediately interpretable or coherent.

 

As expected, the results were not completely unambiguous, but the mostly consistent relationships between implicit attitudes and RWA/SDO provided evidence towards both implicit and explict measures capturing the same underlying construct. These results also provide a useful step forward in our discussion of measurement in this domain, acknowledging the complexity of the tradeoff between reliability and specificity.
