Life Thinning and Gaming Disorder: A Longitudinal Qualitative Registered Report

How do intensive gaming experiences evolve over time in clinical and non-clinical contexts?

Recommended by ORCID_LOGO based on reviews by Peter Branney and Michelle Carras
Over the last 5 years the inclusion of “gaming disorder” in the ICD-11 been controversial (Van Rooij et al, 2018), mirroring wider public debate 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. (2023) tackle this question in the second of two Stage 2 Registered Reports associated with their previous programmatic Stage 1 submission. Using interpretative phenomenological analysis, the authors undertook in-depth interviews over a 1-year period with treatment-seeking participants (N=5) and esports-playing participants (N=4) who did not experience gaming-related health problems. The authors sought to answer the folllwing primary question: How do the experiences and meanings of playing videogames—shaped by the individuals’ diverse sociocultural contexts—evolve in those with related health problems (as defined by treatment-seeking) and those who play esports games several hours per day while self-reporting no related health problems?
 
Both groups exhibited intense relationships with gaming that were cyclical over time across various dimensions, with fluctuations occurring in response to changes in health, occupation, and social networks. The observed variation over time was substantial, with individuals attaching and detaching from games involving hundreds or thousands of hours. The authors report treatment-seeking being followed by a search of new gaming and life meanings, while intensive gaming without related problems continued as an integrated part of the self, with resilience adapting and evolving in the face of unexpected life events. Taking into account their findings, the authors propose life thinning and resilience integration processes to help describe and explain how some individuals end up seeking treatment for their gaming, while for others gaming supports them and becomes integrated into their identity.
 
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.

Globally, songs and instrumental melodies are slower, higher, and use more stable pitches than speech [Stage 2 Registered Report]

Strong evidence for cross-cultural regularities in music and speech

Recommended by ORCID_LOGO based on reviews by Bob Slevc and Nai Ding
For centuries, the ubiquity of language and music across human societies has prompted scholars to speculate about their cross-cultural origins as well as their shared and unique characteristics. Depending on the extent to which contemporary theories emphasise the role of biology vs. culture, a range of hypotheses have been proposed concerning expected similarities and differences in song and speech. One class of hypotheses stemming from cultural relativism assumes a lack of universal regularities in song and speech, and therefore predicts no systematic cross-cultural relationships. On the other hand, more recent evolutionary hypotheses such as the social bonding hypothesis, motor constraint hypothesis, and sexual selection hypothesis all predict differences or similarities in specific characteristic of vocalisations, such as pitch regularity, pitch interval size, and melodic contour. Existing results are mixed in their support of these predictions.
 
In the current study, Ozaki et al. (2023) elucidated cross-cultural similarities and differences between speech and song in 75 different linguistic varieties spanning 21 language families. Understanding precisely how song and speech are related is methodologically challenging due to the multitude of confounds that can arise in comparing natural recordings. Here the authors overcame these difficulties with four types of carefully controlled recordings: singing, recitation of sung lyrics, spoken description of the song, and instrumental version of the sung melody. The authors then examined six features that are amenable to reliable comparison, including pitch height, temporal rate, pitch stability, timbral brightness, pitch interval size, and pitch declination. With this data in hand, the authors asked which acoustic features differ reliably between song and speech across cultures, with the expectation that song would exhibit higher pitch, slower rate and more stable pitch than speech. At the same time, the authors expected song and speech to be reliably similar in the characteristics of timbral brightness, pitch intervals and pitch contours
 
The findings provided strong support for the preregistered hypotheses. Relative to speech, songs exhibited higher pitch, slower temporal rate, and more stable pitches, while both songs and speech had similar pitch interval size and timbral brightness. Only one hypothesis was unsupported, with the comparison of pitch declination between song and speech turning out inconclusive. To overcome potential sources of analytic bias, the authors undertook additional robustness checks, including reanalysis of a previously published dataset of over 400 song/speech recordings; this exploratory analysis corroborated the conclusions from the confirmatory analysis. Overall this study offers a unique insight into the shared global characteristics of langage and music, with implications for understanding their cultural and biological (co)evolution.

Relationship between creativity and depression: the role of reappraisal and rumination

Evidence for a weak relationship between creativity and depressive traits

Recommended by ORCID_LOGO
For centuries, the relationship between creativity and mental health has been a subject of fascination, propelled by the impression that many of the most famous artists in history likely suffered from mood disorders or other mental illnesses. However, with the advent of psychological science – including more precise and diagnostic clinical measures – the empirical evidence for an association between creativity and depressive symptoms has been mixed, with some studies suggesting a positive relationship and others showing either no effect or indicating that the link, if there is one, may be driven by other personality characteristics (Verhaeghen et al., 2005).
 
In the current study, Lam and Saunders used an online design in 201 participants to ask whether creativity is associated with higher depressive traits, and further, whether that relationship depends on two additional variables that could explain an observed positive correlation: self-reflective rumination (repetitive thoughts that maintain a negative mood state) and the frequency with which individuals engage in reappraisal (a regulation strategy that involves reinterpreting an event or situation to diminish its negative impact).
 
Results showed mixed support for the hypotheses. Contrary to expectations, the relationship between creativity and depression was significantly negative rather than positive. However, even though the directionality of this relationship was opposite to predicted, the hypothesis that the association between creativity and depression is mediated by self-reflective rumination was supported. Finally, the results disconfirmed the hypothesis that reappraisal frequency contributes to the relationship between creativity and depression. Exploratory analyses indicated no reliable moderating role of gender. Overall, these findings suggest that creativity and depression may be only weakly related, and that self-reflective rumination could account for that relationship.

Responding to Online Toxicity: Which Strategies Make Others Feel Freer to Contribute, Believe That Toxicity Will Decrease, and Believe that Justice Has Been Restored?

Benevolent correction may provide a promising antidote to online toxicity

Recommended by ORCID_LOGO based on reviews by Corina Logan and Marcel Martončik
Social media is a popular tool for online discussion and debate, bringing with it various forms of hostile interactions –  from offensive remarks and insults, to harassment and threats of physical violence. The nature of such online toxicity has been well studied, but much remains to be understood regarding strategies to reduce it. Existing theory and evidence suggests that a range of responses – including those that emphasise prosociality and empathy – might be effective at mitigating online toxicity. But do such strategies work in practice?
 
In the current study, Young Reusser et al (2023) tested the effectiveness of three types of responses to online toxicity – benevolent correction (including disagreement), benevolent going along (including joking/agreement) and retaliation (additional toxicity) – on how able participants feel to contribute to conversations, their belief that the toxicity would be reduced by the intervention, and their belief that justice had been restored.
 
The results showed the benevolent correction – while an uncommon strategy in online communities – was most effective in helping participants feel freer to contribute to online discussions. Benevolent correction was also the preferred approach for discouraging toxicity and restoring justice. Overall, the findings suggest that responding to toxic commenters with empathy and understanding while (crucially) also correcting their toxicity may be an effective intervention for bystanders seeking to improve the health of online interaction. The authors note that future research should focus on whether benevolent correction actually discourages toxicity, which wasn't tested in the current experiment, and if so how the use of benevolent corrections might be encouraged.

An #EEGManyLabs study to test the role of the alpha phase on visual perception (a replication and new evidence)

Understanding the relationship between alpha oscillations and visual perception

Recommended by ORCID_LOGO based on reviews by Chris Allen, Luca Ronconi and Alexander Jones
For nearly a century, rhythmic patterns in electrical brain activity have been of major interest in neuroscience and electrophysiology, but much remains to be discovered about their causal contribution to cognition and behaviour. Low-frequency oscillations in the alpha band (~8-13 Hz) have been suggested to facilitate the organisation and delivery of visual information to higher-level systems, including those involved in perception and decision-making. If so, visual perception should also operate in cycles that are synchronous with – and determined by – the phase of ongoing low-frequency oscillatory activity.
 
In this #EEGManyLabs study, Ruzzoli et al. (2023) propose a large-scale, multi-lab investigation (9 labs; N=315 human participants) of the relationship between the phase of alpha oscillations and visual perception. The authors focus in particular on replicating a formative study by Mathewson et al. (2009) which reported that during high-amplitude alpha fluctuations, stimulus visibility depended on the time the stimulus was presented relative to the phase of the pre-stimulus alpha activity. In addition, the amplitude of visual evoked potentials recorded with EEG was larger when the target was presented at peaks in pre-stimulus alpha. To explain their findings, Mathewson proposed an influential pulsed inhibition hypothesis in which low alpha power boosts both cortical excitability and stimulus processing (and hence perception), while high alpha power makes stimulus processing dependent on the phase during the alpha cycle at which the stimulus is presented.
 
In the first of (up to) two studies, the authors will seek to directly replicate the key finding of Mathewson et al: that when alpha power is high, the oscillatory phase determines perceptual performance and event-related electrophysiological correlates in a masked visual detection task. Specifically, (a) alpha oscillations are predicted to modulate the probability of perceiving a target stimulus within a single oscillatory cycle, with detection rate associated with separated (and potentially opposite) phase angles, and (b) alpha phase at the onset of the stimulus should drive electrophysiological correlates of stimulus processing (including the amplitude and/or latency of the N1 ERP component).
 
Provided the results of this first study do not conclusively disconfirm these hypotheses, the authors will then conduct a follow-up study in which the temporal predictability of the target onset (in relation to a fixation stimulus) is reduced to test the more severe hypothesis that the observed correlations between alpha phase and perception are linked directly to ongoing oscillations, independent of temporal expectations.

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’.

Causal dynamics of task-relevant rule and stimulus processing in prefrontal cortex

Functional specificity of cognitive updating in human prefrontal cortex

Recommended by ORCID_LOGO based on reviews by Phivos Phylactou
One of the hallmarks of cognitive control is the ability to flexibly update attention and action when goals change. The prefrontal cortex has long been identified as important for such updating, but much remains to be understood about the anatomical and temporal mechanisms that support cognitive flexibility within prefrontal networks. In the current study, Jackson et al. (2024) build upon insights from recent transcranial magnetic stimulation (TMS) and neuroimaging studies to investigate the critical role of prefrontal cortex for updating goals and selecting behaviourally-relevant stimuli.
 
To measure updating, the authors deploy an attentional switching paradigm in which participants selectively attend to one feature of a novel object (colour or form) while ignoring the other feature. On each trial, a symbol (called a rule cue) indicates whether to attend to the colour (green or blue) or to the form (X or non-X) of the upcoming object. By mapping each stimulus response to a separate button press (two buttons for the two colours; two buttons for the two features), the authors can then categorise different types of behavioural errors – focusing especially on attending incorrectly to the task-irrelevant feature (rule error) vs. applying the correct rule but failing to correctly identify the task-relevant feature (stimulus error). If disruption of a specific cortical region causes a selective increase in one type of error, then this would indicate that the stimulated region is important for either rule processing or stimulus processing.
 
The proposal includes a number of key features that add depth and rigor to the investigation. First, to probe the anatomical specificity of cognitive control, the authors will contrast the effect of TMS delivered to different prefrontal regions that reside within different networks and may have divergent roles in cognitive control: the dorsolateral prefrontal cortex (dlPFC, part of the multiple-demand network) and dorsomedial prefrontal cortex (dmPFC, part of the default mode network). Moreover, unlike many previous TMS studies, the authors will use electric field modelling to normalise cortical stimulation strength between regions, enabling a more controlled anatomical comparison. Second, since the task involves responding to a rule cue and then selectively attending to a task-relevant feature, it is likely that a particular brain region could be selectively critical at a specific time – for instance, if dlPFC were important for rule processing then it should only be necessary shortly after (or around) presentation of the rule cue. To capture the temporal specificity of cortical involvement, the authors will apply a short burst of TMS at different times, beginning either +150ms after the cue or +700ms during stimulus processing. In a preliminary study, the authors used magnetoencephalography (MEG) in combination with the same behavioural task and multivariate pattern analysis (MVPA) to identify these epochs for TMS. Finally, the experiment includes a range of additional control conditions and quality checks to rule out alternative explanations of potential findings, such as TMS impairing perception of the rule cue rather than implementation of the rule, and the effect of peripheral TMS artefacts. Overall, the study promises to reveal a range of intriguing new insights into the timecourse and anatomical specificity of cognitive updating, with implications for theories of prefrontal cortical function.

The Effect of Brooding about Societal Problems on Conspiracy Beliefs: A Registered Report

Brooding increases conspiracy beliefs but with practical significance to be determined

Recommended by ORCID_LOGO based on reviews by Matt Williams and Daniel Toribio-Flórez
The world is seemingly awash with conspiracy theories – from well-trodden examples such as fake Moon landings, the 9/11 truth movement, and Holocaust denial, to relative newcomers including COVID as a bioweapon, QAnon, and the belief that the science of climate change has been invented or falsified. While there is a public perception that conspiracy theories are becoming more prevalent, recent evidence suggests that the rate of conspiracism is relatively stable over time (Uscinski et al., 2022). At any point in history, it seems that a certain proportion of people find themselves vulnerable to conspiracy beliefs, but what distinguishes those who do from those who don’t, and what are the causal factors?
 
In the current study, Liekefett et al. (2023) investigated the critical role of rumination – a perseverative and repetitive focus on negative content leading to emotional distress. In particular, the authors asked whether one component of rumination referred to as brooding (dwelling on one’s worries and distressing emotions) has a specific causal role in the formation of conspiracy beliefs. In a series of preliminary experiments, the authors first established a procedure for successfully inducing rumination, identifying various boundary conditions and requirements for a successful design. In the main study (N=1,638 to 2,007 depending on the analysis), they asked whether the induction of brooding causes a significant increase in conspiracy beliefs. Manipulation checks were also included to confirm intervention fidelity (independently of this hypothesis), and exploratory analyses tested the effect of various moderators, as well as the causal role of a complementary manipulation of reflection – a component of rumination in which attention is focused on the issue at hand rather than one’s emotions.
 
As expected by the authors' preliminary work, manipulation checks independently confirmed the effectiveness of the brooding intervention. In answer to the main research question, participants who brooded over the worries and negative emotions associated with an issue were more susceptible to conspiracy beliefs compared to a control group. However, while this effect of brooding was statistically significant, the confidence interval of the effect size estimate overlapped with the authors' proposed smallest effect size of interest (d = 0.20), suggesting that the practical value of the effect remains to be determined.
 
Overall the findings are consistent with a range of psychological theories suggesting that rumination induces negative affect and/or narrows attention to negative information, which in turn may make conspiracy theories seem more probable and render individuals more vulnerable to cognitive bias. The authors note the importance of future work to define the smallest effect of practical significance, analagous to the criteria used to determine the 'minimal clinically important difference’ in medical research.

The Medusa effect: A registered replication report of Will, Merritt, Jenkins, and Kingstone (2021)

Looking (again) at Medusa: Evidence that pictorial abstraction influences mind perception

Recommended by ORCID_LOGO based on reviews by Alan Kingstone and 1 anonymous reviewer
The Medusa effect is a recently described phenomenon in which people judge a person to be more mindful when they appear as a picture (termed L1) than as a picture within a picture (L2). Across a series of experiments, Will et al. (2021) reported that at higher levels of abstraction, images of people were judged lower in realness (how real the person seemed), experience (the ability to feel) and agency (the ability to plan and act), and also benefited less from prosocial behaviour. The findings provide an intriguing window into mind perception – the extent to which we attribute minds and mental capacities to others.
 
In the current study, Han et al. (2023) undertook a close replication of two experiments from the original report by Will et al. (2021), asking first, whether the level of pictorial abstraction influences ratings of realness, agency and experience, and second, whether it also influences prosocial behaviour as measured in the dictator game (with participants predicted to allocate more money to recipients presented as pictures than as pictures within pictures). In the event of a non-replication using the original materials, the authors planned to further repeat the experiments using newly generated stimuli that are better matched for cultural context and more tightly controlled along various dimensions.
 
Results supported all pre-registered hypotheses. Participants rated and perceived L1 stimuli as having significantly higher levels of realness, agency, and experience than L2, and they also allocated significantly more money to L1 recipients than L2 recipients in a dictator game. Furthermore, participants who judged L1 as higher than L2 on all three dimensions also differentiated significantly between L1 and L2 in the dictator game, indicating a relationship between mind perception and prosociality. Overall, the findings confirm that pictures with lower levels of abstraction are perceived as more mindful and are associated with higher levels of prosocial behavior. Consequently, the results suggest that the Medusa effect is a reproducible phenomenon.
 
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.

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.
