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. 

 

A considerable body of research in behavioural economics has established the existence of ambiguity avoidance: the tendency for people, when given a choice between two options, to choose the option for which there is greater certainty about the probabilities of certain outcomes occurring. In a seminal study, Curley, Yates, and Abrams (1986) explored potential psychological explanations of ambiguity avoidance, contrasting five hypotheses: hostile nature (the anticipation that more ambiguous options are biased against oneself), other-evaluation (the anticipation that one’s decision will be evaluated by others), self-evaluation (the anticipation that one's decision will be self-evaluated in the future), forced-choice (in which the less ambiguous option is selected only when all other considerations are equal), and a more general uncertainty avoidance associated with risk aversion. The results favoured other-evaluation as the most promising explanation, with implications in the following decades for research in social psychology, judgment and decision making, behavioural economics, consumer behaviour, and cognitive psychology.

 

In the current study, Yiu and Feldman (2022) plan to revisit the psychological basis of ambiguity avoidance in a large online sample through a replication of key studies from Curley et al. (1986), including extensions to increase methodological rigour and to explore the relationship between ambiguity avoidance and hostility bias, anticipated future regret, and post-choice social judgment from others, as well as trait measures of risk tolerance and ambiguity tolerance.

 

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).

Shame and guilt are powerful negative emotions that are notable for their external vs. internal focus: while shame is generally experienced in response to public scrutiny, guilt arises from a self-directed, private evaluation. In a formative study, Smith et al. (2002) asked whether the level of public exposure influenced levels of shame and guilt arising from one's transgressions, and found that, compared to private situations, public exposure was more strongly associated with shame than with guilt. Since then, these findings have had significant implications for theories and applications of moral psychology.

 

In the current study, Zhang et al.  propose to directly replicate Smith et al. (2002) in a large online sample. In particular, they will revisit the critical questions from Study 1, asking (a) whether public exposure affects the magnitude of shame and guilt over one’s misconduct, and (b) whether stronger moral belief increases guilt and shame over one’s misconduct.

Bug detection is central to software engineering, but what motivates programmers to perform as optimally as possible? Despite a long history of economic experiments on incentivisation, there is surprisingly little research on how different incentives shape software engineering performance. In the current study, Krüger et al. (2022) propose an experiment to evaluate how the pay-off functions associated with different financial incentives influence the performance of participants in identifying bugs during code review. The authors hypothesise that performance-based incentivisation will result in higher average performance, as defined using the F1-score, and that different incentivisation schemes may also differ in their effectiveness. As well as testing confirmatory predictions, the authors will explore a range of ancillary strands, including how the different incentivisation conditions influence search and evaluation behaviour (using eye-tracking), and the extent to which any effects are moderated by demographic factors.

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.
