The link between Empathy and Forgiveness: Replication and extensions Registered Report of McCullough et al. (1997)'s Study 1

Strong evidence that empathy is important for forgiveness

Recommended by ORCID_LOGO based on reviews by James Bartlett and Saleh Shuqair
Forgiveness is a core feature of human psychology in which a person makes a deliberate decision to cease negative emotions or attitudes toward an offender who has done them harm. The concept of interpersonal forgiveness is deeply embedded across societies, but much remains to be understood about how it actually works. What are its key ingredients and why does it occur in the first place? Research in social psychology has demonstrated a range of personal and social benefits of forgiveness, giving rise to two dominant mechanistic accounts – one that positions empathy as the driving factor and another that centres motivated reasoning (Donovan & Priester, 2017).
 
In the current study, Chan and Feldman (2023) sought to replicate a formative study by McCullough et al (1997) that led to the so-called Empathy Model of forgiveness. According to this theory, forgiving is a motivational change facilitated (crucially) by empathy, promoting constructive over destructive behaviour toward the offender. Chan and Feldman replicated Study 1 from McCullough et al., measuring the correlational relationship between apology, forgiving, and empathy for offenders, and exploring whether forgiving is associated with increased conciliation and decreased avoidance motivation. As well as closely replicating the original study, the authors extended it to test the more severe hypothesis that empathy causally influences forgiveness. To achieve this, they experimentally manipulated empathy by adding two groups to the design: one in which participants were asked to recall hurtful past experiences in which they were not empathetic to the offender, and another in which they were highly empathetic.
 
The outcomes constitute a successful replication. Affective empathy was positively associated with perceived apology and forgiveness, and forgiveness was positively associated with conciliation motivation and negatively associated with both avoidance motivation and revenge motivation. In addition, the results of the experimental extension revealed a reliable causal effect of empathy on forgiveness and perceived apology. Overall, the findings provide robust support for the Empathy Model of forgiveness.

Sunk cost effects for time versus money: Replication and extensions Registered Report of Soman (2001)

Mixed evidence for the hypothesis that sunk cost effects are weaker for time than money

Recommended by ORCID_LOGO based on reviews by Christopher Olivola and Dilip Soman
The sunk cost fallacy is a cognitive bias in which people persist with a decision that is no longer optimal because of previous resources they have invested (now considered to be spent or “sunk”). Most of us will have heard sunk costs reflected in the saying “throwing good money after bad”, but sunk costs can, in theory, occur more broadly, whether for money, time or any other resource-limited investment. The sunk cost effect for money has been widely studied and appears robust; in contrast, the sunk cost effect for time is more uncertain, and is potentially moderated by the age of respondents (and likely resource availability), the fact that time is irreplaceable, and the tendency for people to account for time less easily than they do for money. In an impactful study, Soman (2001) found that the sunk cost effect for time was indeed weaker than for money, although this finding has not been widely replicated.
 
In the current study, Petrov et al. (2023) replicated three studies (1, 2 and 5) from Soman (2001), asking whether sunk costs are weaker for time than for money, and then testing whether the relative absence of a sunk time cost arises from the inability of participants to account for time or due to more rational beliefs in the evaluation of past time investments.
 
Results provided mixed support for the original findings. Consistent with Soman (2001), the sunk cost effect for money was reliably stronger than for time in Study 1; however, sunk costs for both money and time were comparable in Study 2 (and if anything, slightly stronger for time). The indirect replication of Study 5 from Soman (2001) found that the sunk cost effect for time was not significantly influenced by accounting for time, either using education or by highlighting opportunity costs. Robustness checks confirmed the main preregistered outcomes while also ruling out a range of potential alternative explanations. Overall, the results suggest that that sunk cost effects for time are more context-dependent and empirically volatile than sunk costs for money.

The role of spatial location in irrelevant speech revisited: A pre-registered replication

Does auditory stream segregation reduce the irrelevant speech effect?

Recommended by ORCID_LOGO based on reviews by Massimo Grassi and 2 anonymous reviewers
The irrelevant-speech effect (ISE) is a laboratory phenomenon in which performance at memory recall is impaired by the presence of irrelevant auditory stimuli during the initial encoding phase. In a typical ISE experiment, participants are asked to remember a sequence of letters presented visually (e.g. F, K, L, M, Q, R, Y in a shuffled random order between trials) while irrelevant speech is played over headphones. The typical finding is that recall performance is impaired by the presentation of speech compared with silence. The ISE has been influential in cognitive psychology, prompting the advancement of two broad classes of competing explanations: one in which the irrelevant sounds gain automatic access to memory processes without any specified role for attentional selection, and another in which the ISE is explained by irrelevant speech drawing attention away from the relevant items to be recalled.
 
In the current study, Kattner et al. (2023) propose a replication of a seminal study by Jones and Macken (1995) that provided a foundation for the automatic access (or ‘interference-by-process’) class of theories. In their original set of experiments, Jones and Macken reported that the segregating individual components of the irrelevant speech (the spoken letters V, J, and X) into different lateralized locations reduced the magnitude of the ISE by converting a single ‘changing-state’ stream three separate ‘steady-state’ streams. Here, Kattner et al. ask firstly whether this classic finding can be successfully replicated in a well-powered sample, and secondly whether the streaming-by-location effect in Jones and Macken reduces the ISE to the same level as observed during a steady-state baseline condition in which a single letter is repeated from each location. If the answer to either question is No then doubts will have been raised about interference-by-process theories, opening the door (even more) to alternative theoretical explanations of the ISE.

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.

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.
 
Following one round of review and revisions, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

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’.

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.
