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) propose an experiment to test the effectiveness of three types of responses to online toxicity – Benevolent Correction (including disagreement), Benevolent Going Along (including joking/agreement), or 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 findings promise to shed light on approaches for improving the health of online discourse.

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.

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.

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.

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).
