Impulsivity and online sports betting behaviour: Untangling the causal relationship (ISPO study)

Examining the causal pathways from impulsivity to disordered gambling in online sports betting

Recommended by ORCID_LOGO based on reviews by 2 anonymous reviewers
Online sports betting is becoming increasingly popular worldwide, which has raised concerns about the negative consequences it has on both individual health and public health. To prevent and reduce these negative consequences, it is important to understand how gambling-related harms arise in the context of online sports betting. 

Impulsivity has long been recognized as a risk factor for disordered gambling, yet how impulsivity may lead to gambling-related harms is not entirely clear. In the current study, Jacob and colleagues (2024) aim to examine this question using a longitudinal cross-lagged panel design. Regular online sports bettors will be invited to fill out measures of impulsivity (including impulsive choice, impulsive action, and impulsivity personality) and gambling disorder symptoms three times at three-month intervals. Player tracking data on these players' online betting behavior in these three-month intervals will then be retrieved from the online gambling provider. Combining these data provides a unique opportunity to test the hypotheses that impulsivity may lead to riskier online gambling behavior, which in turn may lead to more gambling-related problems later on. The results of the current study will offer novel insights into the causal pathways from impulsivity to disordered gambling in online sports betting, and may also inform the development of early prevention strategies to reduce gambling-related harms.

The current Stage 1 manuscript was evaluated by two reviewers and the recommender. 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).

Revisiting the Effects of Helper Intention on Gratitude and Indebtedness: Replication and extensions Registered Report of Tsang (2006)

Grateful or indebted? Revisiting the role of helper intention in gratitude and indebtedness

Recommended by ORCID_LOGO based on reviews by Jo-Ann Tsang, Sarahanne Miranda Field and Cong Peng
When receiving a favor, we may feel grateful and/or indebted to those who have helped us. What factors determine the extent of gratitude and indebtedness people experience? In a seminal paper, Tsang (2006) found that people reported feeling more gratitude when the helper's intention was perceived to be benevolent rather than selfish. In contrast, indebtedness was not influenced by the perceived intention of the helper.

In the current study, Chan et al. (2025) revisited the effects of helper intention on gratitude and indebtedness, by replicating and extending the original studies (Study 2 & 3) by Tsang (2006). Participants were asked to either recall (replication of Study 2) or read (replication of Study 3) a scenario in which another person helped them with either benevolent or selfish intentions, and rate how much gratitude and indebtedness they would experience in such situations. Replicating the findings by Tsang (2006), Chan et al. (2025) found that gratitude was more strongly influenced by helper intention than indebtedness. Extending these findings, the authors further discovered that helper intention affected perceived expectations for reciprocity and reciprocity inclination. Moreover, perceived reciprocity expectations showed opposite correlations with gratitude and indebtedness. Overall, this successful replication reinforces the distinction between gratitude and indebtedness, providing a solid foundation for future research on their underlying mechanisms and downstream influences.

This Stage 2 manuscript was evaluated over one round of in-depth review by three expert reviewers, and a second round of review by the recommender. After the revisions, the recommender judged that the manuscript met the Stage 2 criteria and therefore awarded a positive recommendation.

The capacity of response training to help resist the consumption of sugary drinks

Gamified response training with sugary drinks does not facilitate adherence to a restrictive diet

Recommended by ORCID_LOGO based on reviews by Matthias Aulbach and Pieter Van Dessel
Many people nowadays struggle with maintaining a healthy diet. Despite the intentions to eat healthily, they often over-consume highly palatable yet nutrient-poor foods and drinks, which in turn can lead to many health problems. There is therefore a need to develop tools that can help people resist the (over-)consumption of such foods and drinks. 

Previous work has shown that training people to execute certain motor responses toward food items can modify their liking for these items, which may also influence their subsequent consumption behavior. Based on these findings, Najberg et al. (2023) developed a mobile game that combined two food-related response training tasks, namely the go/no-go training (Veling et al., 2017) and the cue-approach training (Schonberg et al., 2014). The experimental group was trained to consistently inhibit their responses toward sugary drinks in the go/no-go training, and consistently respond to water items in the cue-approach training (i.e., 100% consistent mapping). In the control group, the mapping between an item and response requirement was 50%, such that participants executed both go and no-go responses toward sugary drinks and water. Najberg et al. (2023) found that after the training, the experimental group reported more reduction in liking for sugary drinks and more increase in liking for water items compared to the control group. However, both groups showed equivalent reduction in self-reported consumption of sugary drinks. 

Using the same design (i.e., 100% vs. 50% consistency), in the current study, Najberg et al. (2024) further examined whether the combined go/no-go and cue-approach training game could help people resist the consumption of sugary drinks. Participants were divided into the experimental and control group (N = 100 and 92, respectively), and received the respective training for a minimum of seven days (and up to 20 days). After completing the training, they were asked to avoid the trained sugary drinks. The number of days in which they reported to successfully adhere to this restrictive diet was used as the main dependent variable. Contrary to their predictions, the two groups did not differ in how long they resisted the consumption of sugary drinks after training. Both groups showed equivalent reductions in liking for sugary drinks (contrary to the finding in Najberg et al., 2023), but this reduction in liking was not correlated with the number of successful days of diet in the experimental group. Lastly, those who trained for more days in the experimental group also adhered to the diet for a longer duration, but this correlation might be explained by differences in motivation across individuals.

Together, these results suggest that consistently withholding responses toward sugary drinks and responding to water items does not help people resist the consumption of sugary drinks, compared to a control intervention in which the mapping is 50%. More research is therefore needed to test the effectiveness of food-related response training in changing consumption behavior outside of laboratory contexts.

The Stage 2 manuscript was evaluated over three rounds of review by two expert reviewers who also assessed the Stage 1 manuscript. Following detailed responses to the recommender and the reviewers’ comments, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

The WEIRD problem in a “non-WEIRD” context: A meta-research on the representativeness of human subjects in Chinese psychological research

How well do "non-WEIRD" participants in multi-lab studies represent their local population?

Recommended by ORCID_LOGO based on reviews by Zoltan Dienes, Patrick Forscher and Kai Hiraishi
In this protocol, Yue et al. (2023) aim to clarify whether the sample of non-WEIRD countries included in multi-lab studies is actually representative of those countries and cultures. Focusing on China, this study will compare Chinese samples in several multi-lab studies with participants in studies published in leading national Chinese journals on various aspects, including demographic data and geographic information. This work will provide useful information on the extent to which multi-lab studies are able to deal with generalizability, especially as they intend to address the generalizability problem.
 
The Stage 1 manuscript was reviewed by three experts, including two with an interest in the WEIRD problem and a wealth of experience in open science and multi-lab research, plus an expert in Bayesian statistics, which this manuscript uses. Following multilpe rounds of peer review, and 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).

Sight vs. sound in the judgment of music performance: Cross-cultural evidence from classical piano and Tsugaru shamisen competitions

Understanding the role of visual and auditory information in evaluating musical performance

Recommended by ORCID_LOGO based on reviews by David Hughes and Kyoshiro Sasaki

In this Stage 1 Registered Report, Chiba and colleagues (2021) aim to investigate how people use information from visual and auditory modalities when evaluating musical performances. Previous studies, mainly using Western music, have reported a visual dominance, but this has not yet been clearly and consistently reported. Thus, the authors propose to evaluate both the reproducibility and generalizability of the previous findings by conducting a replication study using the methodology of the previous studies and by introducing a new experimental condition in which the Tsugaru-shamisen, a unique Japanese musical instrument, is also performed. This study could represent an important turning point in the research context of performance evaluation and would be of considerable value.

This manuscript was peer-reviewed by two experts in scientific methodology and Japanese traditional music, respectively, and during the two-round peer-review process they made a number of important points, but eventually awarded the manuscript a highly positive response. I am therefore pleased to recommend that this Stage 1 Registered Report meets our Stage 1 criteria and is worthy of in-principle acceptance. I look forward to seeing the results and discussion reported in Stage 2, with the expectation that the experiment conducted by the authors will be in strict accordance with this protocol.

*The following is a very minor comment, which I hope the authors will find helpful in the future. Of course, this is not related to hypothesis construction and does not require revision: The "Blind Audition" study cited in the introduction is very impactful, but has recently been called into question, so I am at least a little cautious when citing this study. This article may be useful. https://www.wsj.com/articles/blind-spots-in-the-blind-audition-study-11571599303

Sight vs. sound judgments of music performance depend on relative performer quality: Cross-cultural evidence from classical piano and Tsugaru shamisen competitions [Stage 2 Registered Report]

Music is appreciated cross-modally, but is culture- and context-dependent

Recommended by ORCID_LOGO based on reviews by Kyoshiro Sasaki and 1 anonymous reviewer
Music is not merely limited to the aural experience we garner through our auditory faculties, as commonly perceived. Rather, various studies have explored the cross-modal impact of visual stimuli on the evaluation of music. These previous studies have been confined exclusively to Western music. Hence, Chiba et al. (2023) designed a study with a focus on the Tsugaru shamisen, a renowned folk instrument indigenous to Japan, and of which the first author is an outstanding player.

The study methodology was an improved version of previous endeavors, wherein actual musical material sourced from concours performances was displayed through audio-only, video-only or both modalities. A sample of Japanese participants were then asked to evaluate the concours performances on both the piano and the Tsugaru shamisen. The results, obtained through pre-registered protocols, revealed that for both concours performances, the participants displayed a cross-modal impact of visual information on their aural evaluation of music. This effect was also found to be contingent on cultural and contextual factors. These outcomes furnish valuable evidence towards the generalizability of the interplay between sight and sound in the assessment of music.
 
The study underwent rigorous peer-review processes in both Stage 1 and Stage 2, with three experts specializing in Japanese folk music, open science, and statistics, respectively, providing their critical assessments. Following multiple rounds of revision, the final manuscript was deemed fit for recommendation.

Does learning more about others impact liking them?: Replication and extension Registered Report of Norton et al. (2007)’s Lure of Ambiguity

Does familiarity really breed contempt?

Recommended by ORCID_LOGO based on reviews by Philipp Schoenegger and Zoltan Kekecs
In interpersonal evaluation, the amount of information available about the other person has a significant impact. Norton et al. (2007) conducted systematic experiments suggesting a 'less is more' effect – that a lack of information leads to a more positive evaluation. However, subsequent studies have not always reached the same conclusion.
 
In the current study, Horsham et al. (2024) aim to address this issue by conducting direct and conceptual replications of the Norton et al. (2007) experiments, as well as additional extensive experiments focusing on the effects of curiosity. The authors seek to confirm in a reliable way the relationship between ambiguity and liking, and even to clarify the factors that mediate this relationship. The results should significantly advance our understanding of the importance of information management in interpersonal relationships.

Working memory performance in adverse environments: Enhanced, impaired, or intact?

A closer look at working memory changing with adversity

Recommended by ORCID_LOGO based on reviews by Kathryn Bates and 1 anonymous reviewer
Adverse environments involving threat, uncertainty, deprivation and stress can cause significant and long-lasting harm to cognition and development. In this Stage 1 protocol, Vermeent and colleagues (2024) aim to simultaneously test with a single paradigm and statistical model for findings from previous studies showing that human working memory capacity is impaired in adverse environments, as well as other evidence suggesting that adversity may actually enhance updating of working memory. Furthermore, they will also investigate whether working memory is related to each of the adversity types: threat, deprivation, and unpredictability.
 
The findings of this study should help clarify how working memory functions in combination with adversity, and will provide insight into the development of better interventions and training methods for optimal performance in a variety of environments.

Inconclusive evidence for associations between adverse experiences in adulthood and working memory performance

Adversity and working memory: Nuanced effects underpinned by rigorous methodology

Recommended by ORCID_LOGO based on reviews by Kathryn Bates and 1 anonymous reviewer
Adverse environments involving threat, uncertainty, deprivation, and stress have been shown to have significant impacts on cognition and development. In this Stage 2 manuscript, Vermeent et al. (2024) adhere to their Stage 1 protocol, investigating the effects of adversity on working memory (WM) using a comprehensive, psychometric modeling approach. The authors aimed to clarify seemingly contradictory findings from previous research: The evidence for working memory capacity impairments in adverse environments versus the possibility that adversity might enhance specific aspects of WM, such as updating ability. Moreover, they examined the effects of distinct types of adversity—neighborhood threat, material deprivation, and unpredictability—on WM performance.
 
The results of the study were, overall, inconclusive: the authors did not find consistent associations between adversity and either WM capacity or WM updating ability. Despite using a large sample and employing latent variable modeling, the study did not reveal significant effects that were either clearly positive or negative for any type of adversity examined. In addition, no evidence for equivalence to zero associations was found. The lack of clear associations suggests that the relationship between adversity and WM is likely more complex than previously thought.
 
As with the Stage 1 evaluation, this manuscript has undergone a rigorous peer review process at Stage 2. The reviewers included specialists in child and youth cognitive development. The constructive feedback from the reviewers ensured that the pre-registered protocol was followed accurately, deviations were reported appropriately, and all concerns raised were addressed satisfactorily. These processes helped to refine Vermeent et al.'s methods and confirm that the planned analysis was followed. Despite the inconclusive results, this study makes a significant contribution to our understanding of the subtle effects of adversity on working memory by providing transparent and rigorous findings that add valuable data to the field. Therefore, I am fully confident that this manuscript is suitable for Stage 2 recommendation.

Does learning more about others impact liking them?: Replication and extension Registered Report of Norton et al. (2007)’s Lure of Ambiguity

Revisiting ‘less is more’: A failure to replicate the association between increased knowing and decreased liking

Recommended by ORCID_LOGO based on reviews by Philipp Schoenegger and Zoltan Kekecs
Does knowing more about others necessarily lead to greater liking, or might it breed contempt, as suggested by Norton et al. (2007)? In the current study, Horsham et al. (2025) tried to replicate and extend that original question. Collecting data from a large sample of U.S. undergraduates and employing carefully revised designs reviewed at Stage 1, they replicated Norton et al.’s initial studies (1a, 1b, and 2) while also adding new measures. Their primary aim was to see if the “less is more” effect, where increased familiarity decreases liking, would hold under rigorous modern standards, including pre-registration and several open science practices.
 
Results indicated that people indeed believe they will like someone more if they know more about that person, replicating Norton et al.’s initial finding from Studies 1a and 1b. However, the association between greater knowledge and reduced liking, the core of the “less is more” claim, was not consistently observed. Instead, the data showed little evidence that accumulating information inevitably decreases liking. Moreover, an added examination of curiosity as a potential mediator revealed that although curiosity and liking are positively related, curiosity itself was not strongly contingent on the amount of knowledge participants had. These findings help clarify why previous literature has sometimes presented mixed outcomes, and they underline the distinction between what people predict will happen and what actually does happen in forming impressions of others.
 
Peer review involved thorough evaluations by experts. Following multiple revisions through Stages 1 and 2, the manuscript has been deemed a carefully executed Registered Report, providing transparent methods, open data, and full reproducibility. It adds nuance to discussions around how knowledge, familiarity, and curiosity jointly shape our interpersonal attitudes. On this basis, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.​
