How can qualitative research and case studies inform theoretical models of gaming disorder? Gaming Disorder has generated a large amount of research, with up to 95% of it focusing on quantitative studies. As a result, most of the meta-analyses and review studies focus on quantitative research and disregard qualitative approaches. However, studying the direct experiences of gamers can provide more detailed and direct evidence that can feed into theoretical models. 

 

In this Stage 1 manuscript, Auranen et al. (2024) will perform a qualitative meta-analysis of gaming disorder case studies, case reports, and case series of treatment-seekers using a 3-phase approach. First, they will focus on examining the reported problems of participants, the reported reasons for seeking help to reduce their gaming, and the causal link between gaming and reported problems, including the context of these problematic behaviors. Second, thematic synthesis will generate construct themes regarding the contexts of the individuals and the reported problems. Lastly, the authors will examine the relevance of findings in regards to the coping model, value fulfillment theory and the theory of cultural dissonance.

 

The Stage 1 submission was evaluated by the recommender and three expert reviewers, one of which was recused due to conflicts of interest that emerged after the first round of revisions. The recommender and co-recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).

Revisiting a true classic, this registered replication report addresses Kahneman and Tversky’s (1973) introduction of the representativeness heuristic. The heuristic refers to deviations of judgments from normative evaluations of the evidence when the stimulus fits to a prototype. For instance, when an individual is described by features stereotypically associated with a certain target group (e.g., a person who attends dance training several times a week and has a passion for singing and performing), likelihood judgments that the individual belongs to a target group (K-Pop artists) compared to a non-target group (e.g., accountants) are inflated. 

The impact of the original research on the field is clearly immense and long-lasting. All the better that a systematic replication attempt is being undertaken in this registered report, which addresses studies 1 through 7 of Kahneman and Tversky’s classic 1973 paper. Chan and Feldman (2024) propose a well-powered online study, in which all studies from the original article are presented to participants within-subjects. The materials are carefully constructed and closely documented in the accompanying OSF project, where in-depth information on planned data analyses is supported with a simulated dataset.  

The Stage 1 manuscript was evaluated over three 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 6. Data collection commenced during the later part of Stage 1 peer review; however, since no substantive changes to the design were made after this point, the risk of bias due to prior data observation remains zero and the manuscript therefore qualifies for Level 6.

The interplay of music, movement, and cultural experience shapes rhythm perception. From bouncing babies and children at play, to tapping, clapping, and dancing, music often triggers synchronous body movements that can influence how we process rhythm. And, at the same time, long-term exposure to specific musical traditions shapes how we perceive and interpret rhythms.

 

However, direct behavioural and neuroscientific evidence on how these processes occur remains scarce. In this programmatic submission, comprising two complementary Stage 2 reports, Guérin et al. (2024) will investigate how body movements shape the processing of auditory information, and how previous short-term motor practice and long-term cultural experience interact to shape neural and behavioural responses to rhythmic stimuli. The authors will record in separate sessions both  electroencephalography (EEG) and hand clapping, in response to rhythms from West/Central Africa. These recordings will be conducted before and after a session in which participants will clap/step to either a three or a four-beat metre that is expected to influence how they interpret a rhythm.

 

The first Stage 2 report, which will be conducted on African-enculturated participants, aims to demonstrate how body-movement pace flexibly imprints on human sensory processing. The authors build on various theoretical models that emphasise the role of motor production in metre perception, and predict that both neural and behavioural entrainment will improve following movement, matching the rhythmic pattern set by the previous body movements.

 

The second Stage 2 report aims to uncover how short-term motor practice and long-term cultural experience interact to shape responses to rhythmic stimuli, by integrating short-term motor practice and long-term cultural experience. For this, the authors will test separate groups of participants from distinct cultural backgrounds (African vs. Western-enculturated), which are predicted to show neural and behavioural differences in their preferred metric mapping before body movement, and expect that neural and behavioural entrainment will improve after movement, especially for the metre set by prior movements, and more significantly for the metre common in the participant's culture.

 

Together, the findings from the planned Stage 2 reports are expected to clarify how long-term cultural background and short-term motor practice imprint onto rhythm processing in humans. This research will enhance our understanding of how cultural experience, body movement, and neural plasticity interact in music processing.

This study aims to examine the associations between personality traits, using the big-5 personality model (Costa & McCrae, 1992), and compliance with pandemic measures (e.g. handwashing), and perceived risk of the pandemic to the individual, in a representative sample of the adult Norwegian population.

 

Several previous studies have examined associations between personality and adherence to medical advice using measures administered at the same point in time the during COVID-19 pandemic (e.g. Götz et al., 2021), however the dataset the current investigators plan to use assessed personality one year prior to the pandemic (May/June 2019) and the risk and compliance measures four months into the pandemic (August/September 2020). 
 
Here, Sætrevik et al. (2024) make a number of hypotheses, including that conscientiousness, agreeableness, openness and neuroticism will be positively associated with compliance; extraversion will be negatively associated with compliance; extraversion and openness will be negatively associated with perceived risk; and finally, neuroticism will be positively associated with perceived risk. They plan to test their hypotheses using linear regression analyses.
 
Importantly, given the topic, the data for this study already exists and some response distributions of the compliance and risk measures have been examined. However, the authors have yet to link the data on personality to the data on compliance and risk, which is the focus of their hypotheses.  
 
The findings from this study will help us to understand the personality characteristics associated with infection control measures and individual risk perceptions of viral illnesses during a pandemic.

How do perceptions of wastefulness affect how people make choices? In an influential set of studies examining different conceptions of wasteful behavior (overspending, underutilization, and sunk costs), Arkes (1996) found a systematic aversion to wastefulness in decision making, even when choosing to avoid wastefulness has no economic value or works against personal interest. While these findings have been influential in basic and applied research, there have been no attempts to directly replicate the results. Moreover, the original study has several methodological limitations, including the use of relatively small samples and gaps in statistical analysis and reporting.

 

In this Stage 1 manuscript, Zhu and Feldman (2024) propose to conduct a high-powered replication of Arkes (1996) using an online sample of participants. The authors will incorporate several extensions to improve methodological rigor relative to the original article, including added comprehension checks, checks of the wastefulness manipulations, a within-subjects design, and a quantitative analysis of participants’ self-reported motivations for their choices. The results of the study will provide insight into the robustness of the original findings, while also better distinguishing wastefulness aversion from other potential reasons behind participants' decisions.
