Action-Inaction Asymmetries in Emotions and Counterfactual Thoughts: Meta-Analysis of the Action EffectCharting meta-analytic evidence for the action-effectRecommended by Chris Chambers based on reviews by Dan Quintana, Emiel Cracco and priyali rajagopal
Winston Churchill once famously quipped, “I never worry about action, but only inaction.” Churchill, however, may have been an exception to the rule, with psychological research suggesting that people are more concerned about the consequences of actions than inactions. During the so-called “action-effect”, first reported by Kahneman and Tversky (1982), people regret an action leading to a bad outcome more than they do an inaction leading to the same bad outcome In the current study, Yeung and Feldman (2022) propose a wide-ranging meta-analysis to characterise evidence for the action-effect, focusing in particular on emotions and counterfactual thoughts – that is, mental representations of alternative decisions (or “what if” thoughts). Consistent with the expected consequences of the action-effect on emotion, they predict that action will be associated with stronger negative emotions than inaction (when outcomes are negative), and with stronger positive emotions than inaction (when outcomes are positive). The authors also expect action to be associated with a greater abundance of counterfactual thought compared to inaction. In addition to examining the overall reliability of the action-effect (plus a range of exploratory questions), the study will also examine the extent to which the action-effect is moderated by temporal distance (with more recent events or behaviours predicted to associated with a stronger action effect), the type of study design, prior outcomes and social norms, the specificity (vs. generality) of the prior event, and whether the study employed a hypothetical scenario or a real-life event.

Working memory performance in adverse environments: Enhanced, impaired, or intact?A closer look at working memory changing with adversityRecommended by Yuki Yamada based on reviews by Kathryn Bates and 1 anonymous reviewer
Adverse environments involving threat, uncertainty, deprivation and stress can cause significant and long-lasting harm to cognition and development. In this Stage 1 protocol, Vermeent and colleagues (2024) aim to simultaneously test with a single paradigm and statistical model for findings from previous studies showing that human working memory capacity is impaired in adverse environments, as well as other evidence suggesting that adversity may actually enhance updating of working memory. Furthermore, they will also investigate whether working memory is related to each of the adversity types: threat, deprivation, and unpredictability.
The findings of this study should help clarify how working memory functions in combination with adversity, and will provide insight into the development of better interventions and training methods for optimal performance in a variety of environments.
The manuscript was reviewed by two experts and the recommender. Following two rounds of peer review, and based on detailed responses to the reviewers' comments, I, the recommender, judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).

Inconclusive evidence for associations between adverse experiences in adulthood and working memory performanceAdversity and working memory: Nuanced effects underpinned by rigorous methodologyRecommended by Yuki Yamada based on reviews by Kathryn Bates and 1 anonymous reviewer
Adverse environments involving threat, uncertainty, deprivation, and stress have been shown to have significant impacts on cognition and development. In this Stage 2 manuscript, Vermeent et al. (2024) adhere to their Stage 1 protocol, investigating the effects of adversity on working memory (WM) using a comprehensive, psychometric modeling approach. The authors aimed to clarify seemingly contradictory findings from previous research: The evidence for working memory capacity impairments in adverse environments versus the possibility that adversity might enhance specific aspects of WM, such as updating ability. Moreover, they examined the effects of distinct types of adversity—neighborhood threat, material deprivation, and unpredictability—on WM performance.
The results of the study were, overall, inconclusive: the authors did not find consistent associations between adversity and either WM capacity or WM updating ability. Despite using a large sample and employing latent variable modeling, the study did not reveal significant effects that were either clearly positive or negative for any type of adversity examined. In addition, no evidence for equivalence to zero associations was found. The lack of clear associations suggests that the relationship between adversity and WM is likely more complex than previously thought.
As with the Stage 1 evaluation, this manuscript has undergone a rigorous peer review process at Stage 2. The reviewers included specialists in child and youth cognitive development. The constructive feedback from the reviewers ensured that the pre-registered protocol was followed accurately, deviations were reported appropriately, and all concerns raised were addressed satisfactorily. These processes helped to refine Vermeent et al.'s methods and confirm that the planned analysis was followed. Despite the inconclusive results, this study makes a significant contribution to our understanding of the subtle effects of adversity on working memory by providing transparent and rigorous findings that add valuable data to the field. Therefore, I am fully confident that this manuscript is suitable for Stage 2 recommendation.

Revisiting the psychological sources of ambiguity avoidance: Replication and extensions of Curley, Yates, and Abrams (1986)Reducing ambiguity in the psychological understanding of ambiguity avoidanceRecommended by Chris Chambers based on reviews by Leyla Loued-Khenissi and Hayley Jach
A considerable body of research in behavioural economics has established the existence of ambiguity avoidance: the tendency for people, when given a choice between two options, to choose the option for which there is greater certainty about the probabilities of certain outcomes occurring. In a seminal study, Curley, Yates, and Abrams (1986) explored potential psychological explanations of ambiguity avoidance, contrasting five hypotheses: hostile nature (the anticipation that more ambiguous options are biased against oneself), other-evaluation (the anticipation that one’s decision will be evaluated by others), self-evaluation (the anticipation that one's decision will be self-evaluated in the future), forced-choice (in which the less ambiguous option is selected only when all other considerations are equal), and a more general uncertainty avoidance associated with risk aversion. The results favoured other-evaluation as the most promising explanation, with implications in the following decades for research in social psychology, judgment and decision making, behavioural economics, consumer behaviour, and cognitive psychology.
In the current study, Yiu and Feldman (2022) plan to revisit the psychological basis of ambiguity avoidance in a large online sample through a replication of key studies from Curley et al. (1986), including extensions to increase methodological rigour and to explore the relationship between ambiguity avoidance and hostility bias, anticipated future regret, and post-choice social judgment from others, as well as trait measures of risk tolerance and ambiguity tolerance.

STAGE 1
On the neural substrates of mind wandering and dynamic thought: A drug and brain stimulation studyDoes dopamine availability influence the effect of brain stimulation on mind-wandering?Recommended by Maxine Sherman based on reviews by Chris Chambers, Jonathan Smallwood and 1 anonymous reviewer
Mind-wandering broadly refers to the phenomenon by which a person's thoughts are directed towards internally generated states as opposed to being directed towards those that are task-relevant. It has been proposed that mind-wandering and cognitive control are supported by overlapping neural systems. While neuroimaging work has implicated prefrontal cortex in both mind-wandering and cognitive control, studies testing its causal role using transcranial direct current stimulation (tDCS) have been inconclusive.
In this study, Rasmussen and colleagues will test whether the effects of prefrontal cortex tDCS on mind-wandering are mediated by dopaminergic availablility, which is known to be important for cognitive control. Using noninvasive brain stimuluation (prefrontal cortex tDCS vs sham) and a pharmacological intervention (levodopa vs. placebo), the authors will test for a causal role of both prefrontal cortex and dopamine availability in mind-wandering, and whether dopamine availability alters the effect of tDCS on mind-wandering.

While neuroimaging work has implicated prefrontal cortex in both mind-wandering and cognitive control, studies testing its causal role using transcranial direct current stimulation (tDCS) have been inconclusive.
Here, Rasmussen and colleagues (2025) put to a strict test the question of whether the effects of prefrontal cortex tDCS on mind-wandering are mediated by dopaminergic availablility, which is known to be important for cognitive control. Using noninvasive brain stimuluation (prefrontal cortex tDCS vs sham) and a pharmacological intervention (levodopa vs. placebo), they found that contrary to some previous work, stimulation of prefrontal cortex does not alter mind-wandering. By contrast, in the absence of stimulation, increasing dopamine availability via levodopa reduced the frequency of freely moving thought. Together, these results clarify the degree to which prefrontal cortex tDCS and dopamine play a causal role in mind-wandering

Is it Worth the Hustle? A Multi-Country Replication of the Effort Moralization Effect and an Extension to Generational Differences in the Appreciation of EffortAre people who exert more effort in a task seen as more moral?Recommended by Adrien Fillon based on reviews by Jared Celniker, Ignazio Ziano and Michael Inzlicht
This study seeks to understand cultural and age differences in the effort moralization effect, a phenomenon in which people who put more effort into a task are considered more moral, regardless of the quality or the morality associated with the task. This is shown in common phrases such as the “great resignation” or “quiet quitting”, which are mostly used against younger members of the population, in particular generation Z.
Tissot and Roth (2024) propose to conduct a replication of a study from Celniker et al. (2023) which found evidence for this effect, with new samples from Mexico and Germany to test potential cultural differences. They will also test the effect of age on the effort moralization effect. Therefore, the study will be a quantitative analysis.
The authors included an adequate power analysis, alternatives for non-supported hypotheses, and filtering to ensure a high quality of data collection. They already provided an R script and dummy data to ensure the quality of the analysis. The Stage 1 manuscript was evaluated over three rounds of in-depth review. Based on detailed responses to reviewers’ and the recommender’s comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance.

The results indicated a generalization of the effort moralization effect in Germany and Mexico, with important heterogeneity in the effect found, and effects sizes that were smaller than in the original study conducted in the USA. However, no effect was found regarding age, as younger individuals judged effort as being important in the same way as older individuals. It is possible, therefore, that the effort moralization effect is a consistent bias that persists regardless of age.

The Role of Offender Identifiability in Second- and Third-Party PunishmentPunishing OffendersRecommended by Clare Conry-Murray based on reviews by Gilad Feldman and Rajarshi Majumder
When people are less-well-known to us, it can impact how we treat them. People outside our communities may feel more anonymous or de-personalized to us, and this could impact the empathy we feel for them. Indeed, past research shows that people seem to care more for those who are who are identified to us, especially when they are victims of a crime (Small & Loewenstein, 2003). In addition, past research also shows that anonymizing victims can influence criminal behavior (Walters, 2022). Thus, social cognitive factors related to anonymity appear to affect both positive feelings (engaging in empathy) and negative activities (criminal activity) related to victims. It seems likely that anonymity can also affect how people judge criminals themselves.
This paper by Blanke and Twardawski (2024) examines how even minor identifying features can make individuals react differently to a perpetrator of a crime. A picture or name (information that may appear in the press) may impact how people perceive criminals in terms of punishment, empathy, outrage, and blame.
How people respond to anonymous or identified criminals may depend on whether the impact of the crime on the victim is made salient. Similar to the Black Sheep Effect (Marques & Paez,1994), the current paper expects that people who identify with victims are expected to punish a perpetrator more when the perpetrator’s name and image are known. This is similar to the case with an ingroup member in The Black Sheep Effect, where ingroup members are punished more for transgressions than outgroup members. For people who view the situation as a third party (and are thus less connected to the victim), an identified perpetrator is expected to lead to less punishment (and also less outrage and blame, and more empathy).
The current study focuses on pickpocketing since it is a crime that can be committed without identifying oneself to the victim. Future research should examine how the type of event impacts judgments, especially given the stigma of being a victim of some crimes. Littering and other minor violations may be seen as understandable when you see someone as a person, rather than a anonymous, impersonal criminal. On the other hand, there can be stigma to being a victim in some cases, such as the case of sexual harassment, where, research shows, perpetrators are judged more positively if they are identified, and victims, especially women, are judged more negatively if they are identified (Barak-Corren & Lewinsohn-Zamir, 2019).
People around the world engage in moral and legal transgressions, and if our judgments of them are influenced by minor features such as a photo or name, we should take action to treat people more fairly. This research will help to determine if people are influenced by these factors.

Functional MRI brain state occupancy in the presence of cerebral small vessel disease -- a pre-registered replication analysis of the Hamburg City Health StudyReplicable dynamic functional connectivity and cognitive correlates of cerebral small vessel disease in the Hamburg City Health StudyRecommended by Robert McIntosh based on reviews by 1 anonymous reviewer
In a previous analysis of data from 988 participants in the Hamburg City Health Study (HCHS), Schlemm and colleagues (2022) reported significant associations between the extent of cerebral small vessel disease (cSVD) and dynamic functional connectivity measures from resting state fMRI. Specifically, the volume of white matter hyperintensities of presumed vascular origin, a structural indicator of cSVD, was negatively related to the proportion of time (‘fractional occupancy’) spent in the two most occupied functional brain states. Reduced fractional occupancy was also associated with longer times to complete part B of the Trail Making Test.
In the present Registered Report, Ingwersen and colleagues (2023) successfully replicated these associations between structural, functional and cognitive measures in a sample of 1651 HCHS participants not included in the earlier study. An exploratory multiverse analysis found that the associations were generally robust to different brain parcellation and confound regression strategies. These replicable patterns reinforce the idea that cSVD may disrupt the brain’s ability to enter and maintain distinct functional modes, and that these changes in functional dynamics are predictive of cognitive impairment.
The Stage 2 manuscript was assessed over one round of in-depth review. The recommender judged that responses to reviewer comments were appropriate, and that the manuscript met the Stage 2 criteria for recommendation.
