How do emotions interact with cognition? The last 40 years has witnessed the rise of cognitive-appraisal theories, which propose that emotions can be differentiated along an axis of cognitive dimensions such as certainty, pleasantness, attentional activity, control, anticipated effort, and responsibility (Smith and Ellsworth, 1985). Early tests of such theories focused especially on the impact of the valence – pleasantness/unpleasantness – of emotions on judgment and decision-making, finding, for instance, that negative mood induction can heighten pessimistic estimates of risk (Johnson & Tversky, 1983).

 

The Appraisal-Tendency Framework proposed by Lerner and Keltner (2000) refined cognitive-appraisal theory by proposing that specific emotions trigger a predisposition to appraise future (or hypothetical) events in line with the central appraisal dimensions that triggered the emotion, even when the emotion and the judgment are unrelated. For example, an individual who is triggered to become fearful of a heightened risk, such as nuclear war, may then exhibit heightened pessimism about risks unrelated to war. The Appraisal-Tendency Framework also predicts relationships between traits, such as fear, anger and risk-taking/risk-seeking tendencies. In an influential paper, Lerner and Keltner (2001) reported direct empirical support for the Appraisal-Tendency Framework, which aside from its influence in cognitive/affective psychology has had considerable impact in behavioural economics, moral psychology, and studies of consumer behaviour.

 

In the current study, Lu et al. (2024) replicated three key studies from Lerner and Keltner (2001) in a large online sample. Through a combination of replication and extension, the authors probed the relationship between various trait emotions (including fear, anger, happiness, and hope) and trait characteristics of risk seeking and optimistic risk assessment. The authors also examined how the ambiguity of triggering events moderates the relationship between specific emotions and risk judgments.

 

Overall, the results provide mixed support for the predictions of the Appraisal-Tendency Framework. Trait anger and trait happiness were positively associated with risk-seeking and optimistic risk estimates, while trait fear was negatively associated with optimistic risk assessment (although a reliable association between fear and risk-seeking was not observed). The original finding of Lerner and Keltner (2001) that the valence-based approach applied to risk optimism for unambiguous events was not supported. In addition, there was no reliable evidence for a positive relationship between hope and risk-seeking preference or optimistic risk estimates. The authors conclude that future research should consider a wider range of emotions to develop a more complete understanding of the link to risk-related judgment and decision-making.

What determines levels of interpersonal attraction? A long history of research in social psychology has highlighted a range of important factors, such as physical attractiveness, similarity of attitudes and beliefs, reciprocity of feelings, self-disclosure of personal information, and familiarity. One theme that runs through several of these characteristics is the concept of uncertainty, and in particular how reducing uncertainty in knowledge about a person influences levels of attraction. According to the Uncertainty Reduction Theory (URT), as an individual’s uncertainty in a person diminishes, levels of attraction are expected to rise. Previous research, however, has reported a mixed and somewhat complicated relationship between uncertainty and attraction, possibly moderated by the current stage of the interpersonal relationship. 

 

One limitation of this area of enquiry is that the methods used to reduce uncertainty have tended to focus on the amount of available information rather than its quality. This shortcoming has become increasingly salient with the rise of online social networking, where people have a wide range of strategies available to reduce uncertainty through passive (non-interactive) observation, for instance by studying profile details or other online information about a person. In the current study, Kuge et al. (2024) aim to partially fill this gap by examining the role of uncertainty reduction by altering the abstractness (or specificity) of available information, rather than its quantity, particularly in an observational, non-interactive setting. According to the tenets of URT, the authors predict firstly that participants will rate a person described in more concrete terms as more attractive than one described using abstract terms, and secondly that perceived uncertainty will mediate the effect of the abstractness on levels of attraction.

 

To test these hypotheses, the authors begin with an online survey (N=250) to select pairs of sentences with varying levels of abstractness while ensuring they are matched for favourability. Then in the main study (N=1000) they will test the effect of the selected abstract vs. concrete expressions on levels of attractiveness, in addition to control variables such as how confident the participant is in predicting the person’s behaviour, as well as a manipulation check to confirm the effectiveness of the abstractness manipulation. Confirmation of these hypotheses would add support for URT, while disconfirmation may indicate that the theory is inadequate at explaining the drivers of attraction in online unilateral communication.

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. 

 

Alterations in subjective experience, including alterations in the sense of agency (SoA) and reality (SoR), are commonly implicated in direct-verbal suggestions, such as hypnotic suggestions. Although extensively studied, how direct-verbal suggestions can alter the SoA and SoR is not understood (e.g., see Martin & Pacherie, 2019; Zahedi et al., 2024). One class of theories postulates that the alterations in SoA and SoR are related to meta-cognition. For instance, the intention to move or form a mental image can be kept out of conscious awareness, creating a sense of involuntariness (Dienes & Perner, 2007).

Relying on this theory, in the current study Sheldrake and Dienes (2024) postulate that the metacognitive processes related to these alterations can occur by appropriate use of imagination. In other words, by imagining the movement or object to be hallucinated and further imagining the underlying process was outside of awareness, one can elicit alterations in SoA and SoR. To this end, an intervention is devised whereby the participant is repeatedly asked to consider what might help or hinder them from imagining they are unaware of the relevant intention and thereby adjust their imagination. A control group will be asked to increase the feeling of involuntariness or altered reality simply by repeated practice. Afterward, participants will be asked in a test phase the extent to which the suggested experience felt involuntary.
