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.

Human meat consumption is associated with a variety of risks to health, animal welfare, sustainability, and the environment (including greenhouse gas emissions and loss of biodiversity), prompting a growing research effort to develop psychological interventions to reduce it and encourage alternative diets. At the same time, although meat consumption remains the majority choice in the UK, its prevalence is declining, with the proportion of vegetarians and vegans increasing substantially over the last two decades.

 

One potential tool to accelerate behaviour change is to expose people to “dynamic norm” messaging, which, rather than providing static descriptive information about the prevalence of a desired behaviour, emphasises how the desired behaviour is changing over time so that people can begin to conform to the emerging trend. Although promising in theory, previous research offers mixed evidence on the effectiveness of dynamic norms in encouraging a reduction in meat consumption, with some studies suggesting benefits and others showing no effect or even counterproductive effects. The methodological rigour of some studies is also in question.

 

In the present study, Aldoh et al. (2022) will investigate the effectiveness of dynamic norm information (compared to static norms) on several indicators of meat consumption, including interest, attitudes, and intentions toward reducing meat consumption, as well as self-reported meat consumption itself. Using an online sample up to 1500 participants, the authors will also test the role of visual cues (including data trend graphics) in causing any effects and will explore the potential longevity of the intervention over a period of 7 days.

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.

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. (2022) embark on an ambitious project to elucidate cross-cultural similarities and differences between speech and song in 81 different linguistic varieties spanning 23 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 overcome 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 will then examine 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 will ask which acoustic features differ reliably between song and speech across cultures, with the expectation that song will exhibit higher pitch, slower rate and more stable pitch than speech. At the same time, the authors expect song and speech to be reliably similar in the characteristics of timbral brightness, pitch intervals and pitch contours. In addition to these confirmatory tests, the authors will explore variation across a range of additional stimulus characteristics and ancillary research questions.

An interviewee in an intelligence interview can face competing interests in disclosing information: The value in cooperating because, for example, information given leads to the arrest of a narcotics gang, making the neighbourhood safer; and the risk that disclosing the information leads to reprisals from the gang. Different pieces of information will compete with each other for disclosure, depending on this balance of risks to self-interest. According to the disclosure-outcomes management model of Neequaye et al., information will be disclosed more with a high than low probability of reward, as might be straightforwardly expected, but this difference will be larger when there is a low probability of cost rather than a high probability. The high probability of cost will induce more a variable response to the possible benefits.

Neequaye et al. (2023) will invite participants to assume the role of an informant, with the goal of maximizing their points according to stated probabilities of costs and benefits of disclosing pieces of information relating to given scenarios. Then the degree to which each type of information is disclosed in a subsequent interview will be assessed: this way the crucial interaction can be tested.
