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 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).

Registered Report: Are anticipatory auditory predictions enhanced in tinnitus and independent of hearing loss?

Evidence for the role of predictive coding in subjective tinnitus

Recommended by ORCID_LOGO based on reviews by Will Sedley, Pia Brinkmann and Emilie Cardon
Subjective tinnitus is a common disorder in which people experience a persistent sound in the absence of any external source. The underlying causes of tinnitus are debated – although the condition is strongly associated with hearing loss resulting from auditory damage, much remains to be understood about the neural processes that give rise to the phantom perception. Various classes of neurophysiological theories have been proposed, including the “altered gain” model – in which neurons in the auditory pathway increase their responsiveness to compensate for reduced auditory input following hearing loss – and the “noise cancellation” model – in which disrupted feedback connections from limbic regions are unable to tune out phantom signals. Although these theories account for much observed data, they have not been conclusively supported, and their ability to explain tinnitus is limited by the fact that hearing loss and tinnitus can arise independently and at different times.
 
In the current study, Reisinger et al. (2024) tested an emerging alternative theory based on a Bayesian predictive-coding framework (Sedley et al., 2016) in which the alteration of perceptual priors leads the auditory system to expect a sound that, if functioning normally, it should not expect. Using magnetoencephalography (MEG) in a sample of tinnitus patients (and carefully-matched controls for age, gender, and level of hearing loss), they asked whether tinnitus is associated with anticipatory brain activation, tuned to the carrier-frequency of an expected auditory stimulus. Specifically, the authors predicted that if the predictive-coding framework is correct then individuals with tinnitus should show different regularity-dependent pre-activations of carrier- frequency-specific information compared to the control group, while tone carrier-frequencies should be processed normally in tinnitus patients. They also predicted that any such pre-activations should not be related to levels of reported subjective tinnitus distress, as measured with the short version of the Tinnitus Questionnaire (mini-TQ).
 
The results broadly confirmed the hypotheses, with some caveats. Statistically significant differences in regularity-dependent pre-activations were observed between the tinnitus and control groups, however – curiously – the effects appear to be driven by below-chance decoding in the control group, complicating the interpretration. At the same time, consistent with expectations, frequency processing did not differ significantly between individuals with and without tinnitus, and the observed pre-activations were not significantly related to tinnitus distress. Overall, the findings cautiously support the conclusion that chronic tinnitus is associated with maladaptively upregulated predictive neural processing, and that this phenomenon is unlikely to be explained by either tinnitus distress or hearing loss.
 
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.

Revisiting the signal value of emotion in altruistic behavior: Replication and extensions Registered Report of Barasch et al. (2014) Studies 3 and 6

Understanding how motives and emotions driving prosocial actions impact the moral assessment of good doers

Recommended by ORCID_LOGO based on reviews by Thibaut Arpinon and Angela Sutan
Pro-social actions are often driven by emotional factors. For instance, emotions have been shown to play a decisive role in the way we judge the fairness of a situation (affect-as-information theory: e.g., Clore et al., 2001; Storbeck and Clore, 2008), and, thus, how we make decisions. Specific emotions like anger have also been shown to stimulate the motivation to fight injustice (Lerner et al., 2015). At the individual level, people might undertake altruistic actions as a way to relieve themselves from these negative emotions (what Cialdini (1991) calls ‘reflexive distress’) but also because these actions are expected by the social norms (‘normative distress’). Indeed, pro-social actions are usually taken in social contexts, and the perception of one’s behavior by third parties might hinder or facilitate the adoption of pro-social behaviors. Understanding the determinants of the perception of altruistic behaviors is thus a key research question to support pro-social actions in collective settings.
 
In the current study, Woo and Feldman (2024) aim to replicate the seminal work of Barasch et al. (2014), who showed that third parties hold more favorable views of agents undertaking pro-social actions when the latter are motivated by emotions. More precisely, the authors aim to replicate two studies of the original work by conducting a well-powered online experiment (US participants, Prolific, N=1,164). First, they will investigate whether donors who exhibit higher distress regarding the suffering of others are perceived as more moral and authentically concerned for others. Second, they will analyze whether individuals who expect material or reputational benefits from their altruistic deeds are perceived by third parties as less moral than those who act for emotional reasons. In addition to these two replication objectives, the authors propose extensions with pre-registered hypotheses that are inspired by Study 2 from the original work. They seek to investigate whether people are seen as more other-focused when they undertake a prosocial action (donation) and under different expected rewards (material, reputational, emotional benefits).

Reading and vocabulary knowledge in English-Meetei Mayek biliterates

Diversifying our understanding of children’s word learning

Recommended by ORCID_LOGO based on reviews by Maxine Schaefer and 1 anonymous reviewer
The positive relation between word reading and children’s vocabulary development has been extensively documented. That said, like most research in psychology and the behavioral sciences, the available evidence comes predominantly from majority populations. In the context of language learning, that means monolingual speakers or multilingual speakers where there is close alignment between home and school language learning. But what does the relation between word learning and vocabulary knowledge look like when the learning contexts are discordant?
 
In the current study, Pamei et al. (2024) propose to examine this question by investigating word learning and vocabulary development in two languages, English and Meetei Mayek, among a sample of Grade 3 (approximate age 10), students in Manipur, India. In this context, formal literacy education begins in English rather than in students’ regional home language of Meetei Mayek. This fact provides an innovative context in which to understand how a) whether the relation between word reading and vocabulary looks different in the two languages, and b) whether there is linguistic interdependence between learning in the two languages. This study is poised to bring important underrepresented data that goes beyond the dominant contexts from which our knowledge of language learning has been generated, and thus has the potential to contribute to new lines of empirical and theoretical work that is inclusive of global variations.

The role of positive and negative emotions on multiple components of episodic memory (“what”, “when”, “in which context”) in older compared to younger adults: a pre-registered study

The role of emotion and age on different facets of episodic memory (“what”, “when”, “in which context”) 

Recommended by ORCID_LOGO based on reviews by Mara Mather and 1 anonymous reviewer
How does emotion influence item memory (what?) temporal memory (when?) and associative memory (in which context?), and does this differ for younger and older adults? Previous research has found inconsistent results, possibly due to small sample sizes. In this study, Laulan and Rimmele (2024) and will build on the paradigm in Palombo et al. (2021) in which participants see images embedded in videos and are asked to remember the images (what?), their temporal position within the videos (where?), and the association between the images and the videos (in which context?). Image valence (positive vs negative vs neutral) and participant age-group (18-30 vs 60-80 yr olds) are manipulated. Pre-registered analyses will first look at the two age groups separately to test for an effect of valence for each of the memory components, and second test for modulating effects of age-group. To be cost-effective, a sequential analysis approach with statistical analyses conducted at three time points and a maximum sample size of 150 younger and 150 older adults is planned.

Assessing compliance with UK loot box industry self-regulation on the Apple App Store: a 6-month longitudinal study on the implementation process

Does self regulation by gaming companies for the use of loot boxes work?

Recommended by ORCID_LOGO based on reviews by Chris Chambers, Lukas J. Gunschera and Andy Przybylski
Video games may provide the option of spending real money in exchange for probabilistically receiving game-relevant rewards; in effect, encouraging potentially young teenagers to gamble. The industry has subscribed to a set of regulatory principles to cover the use of such "loot boxes", including 1) that they will prevent loot box purchasing by under 18s unless parental consent is given; 2) that they will make it initially clear that the game contains loot boxes; and 3) that they will clearly disclose the probabilities of receiving different rewards.
 
Can the industry effectively self regulate? Xiao (2024) will evaluate this important question by investigating the 100 top selling games on the Apple App Store and estimating the percentage compliance to these three regulatory principles at two time points 6 months apart.

Genetically-modified animals as models of neurodevelopmental conditions: a review of systematic review reporting quality

Evidence for mixed quality of systematic reviews in preclinical animal studies of neurodevelopmental conditions

Recommended by ORCID_LOGO based on reviews by Marietta Papadatou-Pastou
Single gene alterations have been estimated to account for nearly half of neurodevelopmental conditions (NDCs), providing a crucial opportunity for animal models to understand the underlying mechanisms, causes and potential treatments. The use of systematic reviews (SRs) can, in principle, provide a powerful means to synthesise this evidence-base; however, the reporting quality of previous SRs in preclinical animal research has been found lacking (Hunniford et al., 2021). In the current study, Wilson et al. (2023) will undertook a review of systematic reviews to assess the characteristics and reporting quality of SRs that, in turn, synthesise research in genetically-modified animals to model NDCs. In particular, the authors extracted key features of reviews (including, among others, the aim and primary research questions, relevant animal model, and number of studies in the SR), in addition to quality indicators such as risk of bias and completeness of reporting. In doing so, the authors aimed to enhance guidance on the conduct and reporting of systematic reviews in this area.
 
Of twelve publications that met the preregistered search criteria, the completeness and quality of reporting was variable. Among the better reported characteristics were search strategies (9 of 12 articles), reporting of funding sources (10 of 12 articles) and use of animal data (11 of 12 articles). In contrast, only two articles reported whether the study protocol was preregistered, only three articles reported methods for assessing risk of bias, and just one included methods to analyse publication bias. In addition, the authors identified 19 review registrations via PROSPERO, most of which remained unpublished after their anticipated end dates. Overall, the results highlight the importance of adherence to reporting guidelines for increasing the transparency and reproducibility of SRs in this field.
 
The Stage 2 manuscript was evaluated over one round of in-depth review. Based on detailed responses by the authors, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

Changes in memory function in adults following SARS-CoV-2 infection: findings from the Covid and Cognition online study

Is memory affected in the long run following SARS-CoV-2 infection?

Recommended by ORCID_LOGO based on reviews by Phivos Phylactou, Dipanjan Ray and Mitul Mehta
COVID-19 has been suspected to have long-lasting effects on cognitive function. The SARS-CoV-2 virus may enter the central nervous system (Frontera et al., 2020; Miners, Kehoe, & Love, 2020), explaining the observed detrimental effects of COVID-19 on verbal planning and reasoning (Hampshire et al., 2021; Wild et al., 2021), executive function (Hadad et al., 2022), and long-term memory (Guo et al., 2022). In particular, Guo et al. (2022) used verbal item recognition and non-verbal associative memory tasks. Weinerova et al. (2024), in the current study, propose to conduct a replication of Guo et al. (2022), but specifically, to disentangle the effect of COVID-19 infection status on both memory type (item vs. associative) and stimulus modality (verbal vs. non-verbal). Furthermore, Weinerova et al. (2024) propose to analyze cognitive function based on vaccination status before infection to provide a critical test of the potential protective effects of vaccination on cognitive function.

Data collection has been completed with 325 participants after exclusion criteria were applied (COVID group N = 232, No COVID group N = 93). Simulations assuming an effect size observed in Guo et al. (2022), a Bayesian t-test comparing the groups, and a Bayes Factor of 6 indicated that N = 320 is sufficient to detect an effect on 79% of simulations. The main analyses will be conducted using a Bayesian ANCOVA that allows for the inclusion of control variables such as age, sex, country, and education level. Both accuracy and reaction times from the item and associative recognition tasks will be analyzed as the dependent variables. In one analysis, vaccination status will be included as a between-subjects factor, to understand whether vaccination status at the time of infection influences subsequent cognitive function. 

It is important to note that participants were recruited through long-COVID Facebook groups and clinics. Therefore, the results must be interpreted carefully to avoid generalizing to all COVID-19 infections. The data are part of a larger longitudinal study, and the current pre-registration applies only to the baseline timepoint for a cross-sectional analysis. The remaining longitudinal data collection is ongoing and is not part of the current pre-registration.  

The study plan was refined after one round of review, with input from three external reviewers who all agreed that the proposed study was well-designed and scientifically valid. The recommender then reviewed the revised manuscript and judged that the study met the Stage 1 criteria for in-principle acceptance (IPA).

Revisiting the motivated denial of mind to animals used for food: Replication Registered Report of Bastian et al. (2012)

Confirmatory evidence that the denial of animal minds explains the "meat paradox"

Recommended by ORCID_LOGO based on reviews by Brock Bastian, Ben De Groeve and Florian Lange
The psychology of meat-eating offers a fascinating window into moral reasoning, cognition and emotion, as well as applications in the shift toward more sustainable and ethical alternatives to meat consumption. One key observation in this field is the so-called “meat paradox” – the tendency for people to simultaneously eat meat while also caring about animals. One way to resolve this conflict and reduce cognitive dissonance is for people to separate the concept of meat from animals, mentally disengaging from the origins of meat in order to make the act of consumption more ethically acceptable. Another potential explanation is a motivated “denial of mind”, in which people believe that animals lack the mental capacity to experience suffering; therefore, eating an animal is not a harm that the animal will experience. In support of the latter hypothesis, Bastian et al (2012) found that animals judged to have greater mental capacities were also judged as less edible, and that simply reminding meat eaters that an animal was being raised for the purposes of meat consumption led to denial of its mental capacities.
 
Using a large-scale online design in 1000 participants, Jacobs et al. (2024) replicated two studies from Bastian et al. (2012): asking how the perceived mental capabilities of animals relates to both their perceived edibility and the degree of moral concern they elicit, and whether learning that an animal will be consumed influences perceptions of its mental capabilities. The original findings were successfully replicated. For study 1, attributions of mind were negatively related to animals’ edibility, positively related to negative affect towards eating animals, and positively related to moral concern for animals. For study 2, learning that an animal would be used for food led participants to attribute less mind to the animal. Overall, the results strengthen the conclusion that motivated denial of animal minds can be a mechanism for resolving the ‘meat paradox’.
 
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.
