Phenomenological Strands for Gaming Disorder and Esports Play: A Qualitative Registered Report

The lived experience of gamers: a comparative qualitative investigation of treatment-seekers and esports players

Recommended by ORCID_LOGO based on reviews by Malte Elson and Peter Branney
Since 2018, the inclusion of “gaming disorder” in the ICD-11 has been met with a mixture of interest, confusion and controversy (Van Rooij et al, 2018), mirroring broader debates about the effects of gaming on mental health. One of the major gaps in understanding the validity of gaming disorder as an identifiable mental illness is the absence of qualitative studies comparing the lived experience of gamers who seek treatment with esports players who do not report health problems.
 
Here, Karhulahti et al. (2022) tackle this question in the first of two Stage 2 Registered Reports associated with their previous programmatic Stage 1 submission. Using interpretative phenomenological analysis in gamers and medical experts, they find that treatment-seekers and esports players differ in how gaming is associated with the sense of self, either interfering with the self for treatment-seekers or successfully integrating into the self for esports players. These findings help to identify the key characteristics of problematic and non-problematic gaming and call for more intensive and wide-reaching qualitative research in this area.
 
Following one round of in-depth review and revision, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

Fathers learning on the job: Role of Paternity Leave Duration on Paternal Infant-Directed Speech and Preference for Male Infant-Directed Speech in infants

Dads and baby talk: understanding the role of paternal interaction in infant-directed speech

Recommended by ORCID_LOGO based on reviews by Naja Ferjan Ramírez, Melanie Soderstrom and Krista Byers-Heinlein
Infant-directed speech (IDS) – colloquially known as “baby talk” – is a form of speech produced by parents that may be important for emotional bonding with children while also helping infants with early language development. In contrast to adult-directed speech (ADS), IDS is characterised by a higher and broader pitch range, slower speech rate, and shorter/simpler syntax. A significant body of research has studied the dynamics of IDS and shown that infants prefer IDS over ADS, however the great majority of this work has focused on maternal speech, leaving much to be discovered about the differences and similarities between paternal and maternal IDS, the relative preference infants exhibit for paternal IDS compared with ADS, and the role of paternal interaction in shaping these dynamics.
 
Using a Norwegian sample of 70 fathers and children, the proposed study by Robberstad et al. (2022) takes an important step into this less-explored domain, asking whether (and if so, how) fathers employ IDS when interacting with infants, whether any such modulation of speech is related to the amount of time they spend as a caregiver, whether infants show the same preferences for IDS over ADS in fathers as observed previously in mothers, and whether that preference is related to the amount of exposure the infant has to parental speech. The authors will analyse speech modulation using acoustic analysis, while preference for IDS will be tested using eye-tracking to measure infants’ overt gaze orientation while listening to IDS vs ADS.

Exploring How Members of Illicit Networks Navigate Investigative Interviews

What to say to help one's partners in crime

Recommended by ORCID_LOGO 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.

Does alleviating poverty increase cognitive performance? Short- and long-term evidence from a randomized controlled trial

No strong effect of unconditional cash transfers on cognition

Recommended by ORCID_LOGO based on reviews by Charlotte Pennington and Matúš Adamkovič
Recent studies have revealed potential benefits of unconditional cash transfers (UCTs) on a variety of health and social outcomes, including self-reported happiness and life satisfaction (Haushofer & Shapiro, 2016), economic and financial well-being (Blattman et al., 2013; Baird et al., 2018) and educational attainment (Baird et al., 2016). Although the effects of UCTs do not always out-perform rigorous control conditions (Whillans & West, 2022), these findings prompt the question of whether the alleviation of poverty via UCTs can also influence cognitive processing and performance.
 
In the current study, Szaszi et al. analysed the results of a previous randomised trial of UCTs by Blattman et al. (2017) to test whether a $200 lump sum – equivalent to three months of income – administered to a sample of young men in Liberia carries both short- and long-term benefits for a range of executive functions, including attention, response inhibition, and working memory capacity. Overall, the results suggest minimal if any consequences of the intervention – the observed effects of UCTs on cognition were several times smaller than suggested by previous research, and the evidence for a positive effect was inconclusive. Extensive multiverse analyses showed that these findings were robust to a range of alternative analytical specifications, and the authors estimate that a sample size of nearly 5000 would be required to provide strong evidence.
 
In their Discussion, the authors explore a range of reasons for the negative findings compared with previous research, including the more rigorous and severe causal test enabled by the randomised trial design, the demographic homogeneity of the sample demographic, the use of pen-and-paper tests (cf. computerised tests in previous studies), and the delivery of a lump-sum cash transfer compared with a regular monthly installment. In addition, although the results were negative or inconclusive, there were hints that a positive effect of UCTs may be more evident in some cognitive domains than in others – in this case, potentially benefiting working memory more than inhibitory control. Further research would be required to confirm this hypothesis.
 
The Stage 2 manuscript was evaluated over one round of in-depth review. Based on the responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

How does the phrasing of house edge information affect gamblers’ perceptions and level of understanding? A Registered Report

Does relaying ‘house edge’ information influence gambler’s perceived chances of winning and their factual understanding of the statistical outcomes?

Recommended by ORCID_LOGO based on reviews by Zhang Chen, Graeme Knibb and Luke Clarke
Many products that can impact upon health and wellbeing (e.g. alcohol, food) relay information to consumers about the potential risks. However, such information is commonly provided in suboptimal format for gambling-related products. To encourage safer gambling, research has therefore recommended that information about the average loss from a gambling product (“house edge”) or percentage payout (“return-to-player”) should be communicated, with the former translating to better perceived understanding by gamblers. In this study, Newall et al. (2022) aim to experimentally compare two phrasings of the house edge against a control return-to-player to arrive at the most effective phrasing to aid gambler’s perceived chances of winning and their factual understanding of the statistical outcomes of their bet. Using a hypothetical gambling scenario, a sample of 3,000 UK-based online gamblers will be randomly assigned to receive two alternative phrasings of the house edge or the equivalent return-to-player information. Two outcome measures will be used to judge the effectiveness of the house edge information: gamblers’ perceived changes of winning and rates of accurate responding on a multiple-choice question measuring factual understanding of this information. This study will therefore assess the most effective communication of gambling risk, which can inform public health policies to reduce gambling-related harm.
 
Following a positive initial appraisal, and after two rounds of in-depth review, the recommender judged that the manuscript met the Stage 1 criteria and awarded in-principle acceptance (IPA).

Neuroanatomical Correlates of System-justifying Ideologies: A Pre-registered Voxel-based Morphometry Study on Right-Wing Authoritarianism and Social Dominance Orientation

No definitive evidence for neuroanatomical correlates of system-justifying ideologies

Recommended by ORCID_LOGO based on reviews by Bonni Crawford and 1 anonymous reviewer
According to the tenets of system justification theory, system-justifying ideologies are beliefs held by individuals to defend and justify the status quo, even when doing do perpetuates social inequalities (Jost and Hunyady, 2005). Two such well-studied ideologies to emerge from political science and social psychology are social dominance orientation (SDO) – the belief that some social groups are superior to others – and right wing authoritarianism (RWA) – the belief that people should follow conventional traditions and authorities, avoiding rebellious ideas. Although considered to be stable traits that may have a heritable basis, there has been little investigation of the neural correlates of SDO and RWA, and it remains unknown whether they are associated with common or distinct brain systems.
 
In the current study, Balagtas et al. report a novel investigation of the neuroanatomical correlates of both SDO and RWA in a Chinese Singaporean sample using voxel-based morphometry. Based on previous research, the authors chose to focus especially on relationships between SDO, RWA and the volume of the amygdala, ventromedial prefrontal cortex, and anterior insula.
 
As predicted, the results showed a reliable positive correlation between measures of RWA and SDO; however, none of the neuroanatomical hypotheses were fully supported. Preregistered whole brain analyses revealed no significant regions associated with either RWA or SDO, while ROI analyses identified overlapping (including the amygdala and ventromedial prefrontal cortex) and non-overlapping regions (including left anterior insula) associated with RWA and SDO. Exploratory robustness checks suggested that the authors' spherical ROI localisation method may have identified clusters that were not within the amygdala or left anterior insula, prompting the need for future replication in a larger sample using more precise, atlas-based analyses.
 
The Stage 2 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 2 criteria and awarded a positive recommendation.

Breaking Ban: Belgium’s ineffective gambling law regulation of video game loot boxes

Loot boxes remain prevalent in Belgium despite their “ban”

Recommended by ORCID_LOGO 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.

Psychological predictors of long-term esports success: A Registered Report

What psychological factors predict long-term success in esports?

Recommended by and ORCID_LOGO based on reviews by Justin Bonny and Maciej Behnke
Electronic sports (esports), the competitive play of video games, has seen a large surge in popularity over the past few decades. Millions of people nowadays participate in esports as a hobby, and many consider becoming professional esports athletes as a potential career path. However, psychological factors that may predict one's long-term success in esports have remained unclear.

In the current study, Martončik and colleagues (2023) propose to examine potential predictors of long-term esports success, in three currently most impactful PC esports games, namely League of Legends, Counter Strike: Global Offensive, and Fortnite. Based on an extensive review of the literature and four pilot studies, the authors will examine to what extent naive practice and deliberate practice, as well as other psychological factors such as attention, speed of decision-making, reaction time, teamwork, intelligence and persistence, can predictor player's highest rank in the past 12 months, as an indicator of long-term success. Deliberate practice has been proposed to play an essential role in the development of expertise in other domains, and the current study offers a test of the role of both naive and deliberate practice in long-term esports success. The novel measurement on naive and deliberate practice, developed as part of the current investigation, will also be a valuable contribution to future research on esports. Lastly, from an applied perspective, the results of the current study will be of great interest to individuals who are considering pursuing a professional career in esports, as well as professional and semi-professional esports teams and coaches.

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

Is the past farther than the future? A registered replication and test of the time-expansion hypothesis based on the filling rate of duration

The Temporal Doppler Effect may not be a robust and culturally universal phenomenon

Recommended by ORCID_LOGO based on reviews by Chris Chambers and 1 anonymous reviewer
The Temporal Doppler Effect refers to the subjective perception that the past is further away than the future even when both temporal distances are objectively the same from the present moment (Caruso et al., 2013). In the current study, Zhang et al. ran a replication of this phenomenon and tested one possible explanation for it, namely that people overestimate the temporal distance of the past because the past is filled with more events than the future. This is because we can access information only about planned events for the future, but have access to both planned and unplanned events that happened in the past (filled-duration illusion; Thomas & Brown, 1974).
 
Over two studies, the authors found that the sampled participants reported feeling that the past was psychologically closer than the future, which is the opposite of what has previously been reported and termed the Temporal Doppler Effect (Caruso et al., 2013). In addition, the authors reported inconsistent results regarding the correlations between the psychological distance and different variables associated with the filling rate of duration. The authors discuss the differences between their own results and those by Caruso et al. (2013) in terms of methodological and contextual differences and highlight cultural aspects that may be critical to consider in future replications and overall testing of this phenomenon. As such, they highlight that, at the moment, the Temporal Doppler Effect should not be considered a robust and culturally universal phenomenon.

Removing barriers to plant-based diets: assisting doctors with vegan patients

Informing doctors of the evidence on plant-based diets

Recommended by ORCID_LOGO based on reviews by Alaa Aldoh, Joshua Tasoff and Bence Palfi
What the best diet is has always been an area of contention. But one thing is clear: Meat is not necessary for health or fitness, and a diet high in plant proteins may well be especially healthy (e.g. Herpich et al., 2022). Further, plant- rather than animal-based diets leave a lower carbon footprint. So what might hold people back from adopting a plant-based diet? One reason is that people may understandably approach their doctor for advice; and the doctor may advise against it, given that many doctors are not well trained in nutrition (Crowley et al., 2019).

Espinosa et al. (2022) conducted a randomised control trial on French general practitioners with 200 doctors given a leaflet and access to an online platform, and 200 controls. The information in the materials concerned the health benefits of plant-based diets, and what nutrients (e.g. B12) may be deficient and what may not be. Attitudes towards and knowledge about plant-based diets was assessed. On a scale of 0-100% expressing whether they would advise for or against (0 = not at all, 100 = absolutely), the intervention shifted attitudes making them more positive about plant based diets by 17 percentage points. However, knowledge of specifically what is worth testing for (e.g. is zinc deficiency more probable or not?) did not change much. The research shows just what can be achieved by a small leaflet (shifting attitudes) and what may require more extensive training (knowledge of relevant medical practice).

The Stage 2 manuscript was evaluated over one round of in-depth review. Based on the responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.
