Do Ecological Valid Stop Signals Aid Detour Performance? A Comparison of Four Bird Species

What is the role of sensory perception in cognitive task performance? An improved replication of detour performance in four different bird species

Recommended by ORCID_LOGO based on reviews by Christian Nawroth and 1 anonymous reviewer
The detour task, where an individual has to go around a see-through barrier in order to reach a goal, is one of the oldest paradigms used in animal cognition research (Kabadayi et al. 2018). While these previous tests have documented variation in the ability of animals to inhibit going straight for the visible reward, the cognitive underpinnings of this behaviour are as yet not fully understood. In the current study, Dewulf et al. (2025) assessed one of the specific cognitive processes that might be involved in this behaviour, the ability to identify the transparent object as a barrier. Through experimental procedures relying on large samples of individuals from four bird species, they compared the role of signal detection in inhibitory response performance in a detour task. The authors found that, unlike suggested in previous work with these four species (Regolin et al. 1994, Zucca et al. 2005), changing the markings on the barriers to potentially better match those experienced by individuals in their natural environments did not improve their performance. Nevertheless, the detailed further explorations suggest that in order to understand variation in how quickly individuals and species solve the detour task, it is important to consider that different cognitive processes are involved. Their work therefore provides a basis to better understand and further investigate why species might differ in their performance in the detour task.

Action interpretation determines the effects of go/no-go and approach/avoidance actions on food choice

Does interpretation of actions as either avoid or inhibit influence choice behaviour for candy?

Recommended by based on reviews by Alexander MacLellan and Katrijn Houben
Experimental research demonstrates that executing or inhibiting motor responses (or approaching / avoiding) towards a stimulus can alter the valuation of the stimulus (Yang et al., 2022). There are competing theories as to the proposed mechanisms of value change, such as increased response conflict or prediction errors (Houben & Aulbach, 2023). However, research has mostly examined response execution/inhibition and approach/avoidance in isolation and the few studies that have examined these together have focused on stimulus evaluation as an outcome.
 
In the current study Chen et al. (2025) set out to examine how action interpretations (e.g. go vs approach) can impact individuals food-choices. This is important for cognitive bias modification approaches which aim to manipulate these actions to promote behaviour change (Iannazzo et al., 2024; Veling et al., 2021), but also theoretical accounts which suggest certain motor-responses acquire valence. Here there are two groups randomised to receive instructions to either go/no-go or approach/avoid images of candy in novel training task (Chen et al., 2019).
 
The results of the experiment suggested that despite both groups making the same responses (pressing a space bar vs not), the framing of the response as go vs approach and no-go vs avoidance influenced subsequent food-choice (i.e. responses framed as approach increased the probability of choosing approach items over avoidance items, but not go items over no-go items).
 
As the authors state, these findings cast doubt on theoretical models which suggest there are ‘hardwired’ links between specific go/approach responses and appetitive systems or specific no-go/avoidance responses and aversive systems. They also suggest these responses aren’t valenced, but acquire valence through interpretation of the action. These findings can also inform future studies into cognitive bias modification.
 
The Stage 2 manuscript was evaluated over two rounds of in-depth review by two reviewers with expertise in the relevant area, who also assessed the Stage 1 manuscript. Based on the authors’ careful responses and revisions, the revised manuscript was judged to meet the Stage 2 criteria and was awarded a positive recommendation.

Disentangling the Influences of Curiosity and Active Exploration on Cognitive Map Formation

Investigating influences of curiosity and active exploration on spatial memory

Recommended by ORCID_LOGO based on reviews by Alexandr Ten and 2 anonymous reviewers
A growing body of research suggests that feelings of curiosity are associated with better memory for new information. However, while curiosity has been broadly defined as an instrinsic drive to obtain information, much of this existing work has focused on learning of trivia facts or factual information, settings where people have relatively little freedom to actively explore aspects of the environment that generate those feelings of curiosity. In this Stage 1 manuscript, O'Donoghue, Cen, and Gruber (2025) propose to conduct an experiment to examine whether feelings of curiosity promote the formation of cognitive maps when exploring novel spatial environments. Participants will encounter a series of virtual rooms for which they report their level of curiosity before exploring each room. The experiment will compare groups of participants who can actively explore for themselves vs. passive observers of the same exploration patterns. The proposed analyses will examine whether anticipatory curiosity leads to better memory for the spatial environments for both active or passive participants, or if benefits to memory are mediated by active participants' ability to act of their feelings of curiosity through their exploration of the environment. The findings of the study will provide new insight into the mechanisms through which anticipatory curiosity enhances memory.

Evaluating Loneliness Measurements across the European Union

Measuring loneliness in the European Union

Recommended by ORCID_LOGO and ORCID_LOGO based on reviews by Thuy-vy Nguyen, Joe Bathelt, Drew Altschul and Mary Louise Pomeroy
Loneliness is increasingly a focus of governments and health systems due to its potential adverse effects. Various ways to measure it have been developed but the psychometric properties of common instruments have not yet been evaluated across all countries in the European Union (EU).
 
In this study, Paris et al. (2025) will examine three measures of loneliness across 27 EU member countries. An online survey (n = 25,646) incorporated three instruments which were translated into national languages: the De Jong Gierveld Loneliness Scale (6 items), the three-item UCLA Loneliness Scale (3 items), and a single-item measure (“How much of the time, during the past 4 weeks, have you been feeling lonely”). The factor structure, internal consistency, and measurement invariance for the 6- and 3-item measures will be assessed, as well as the construct validity of all three measures using nomological networks. The authors have adopted an n-fold procedure to analyse the data, with a first exploratory fold using half of the data to establish hypotheses for each question and a second confirmatory fold using the remainder of the data to test the hypotheses. The results of the study will provide important information about the psychometric properties of commonly used loneliness instruments, and can indicate which measures are appropriate for loneliness monitoring across the EU.
 
The study plan was refined across four rounds of in-depth review with input from four reviewers, Thuy-vy Nguyen, Joe Bathelt, Mary Louise Pomeroy, and Drew Altschul, and the recommenders, after which it was judged to meet the Stage 1 criteria and received in-principle acceptance.

Michotte's research on perceptual impressions of causality: a registered replication study

Michotte’s classic studies on the perception of causality: Replications, extensions and a sound base for further research

Recommended by ORCID_LOGO based on reviews by Maxine Sherman and 1 anonymous reviewer
Making causal judgements are part of everyday life, whether seeking to understand the action of complex humans or the relations between inanimate objects in our environments. Albert Michotte’s (1963) classic book, The perception of causality, contained an extensive report of experiments demonstrating not only that observers perceive causality of inanimate shapes, but do so in manifold ways, creating different “causal impressions.” This work has been highly influential across psychology and neuroscience. 
 
In the current study, White (2025) conducted 14 experiments aimed at replicating and extending Michotte’s work. Despite the fact that this research is foundational to current work on perception and understanding of causal relations, it has never been subject to rigorous replication. Moreover, like many research studies from that era, Michotte was sparse on details about methodology and did not rely on statistical analysis. White carried out an ambitious set of 14 experiments and 18 hypotheses that directly replicated and, in some cases, extended Michotte’s experiments. The results of the experiments were mixed, with the hypotheses evenly divided among being supported, partially supported, and not supported. The current effort by White not only brings rigorous contemporary data to classic studies of perceptual impressions of causality, but the results point to important new directions for future study on the topic. In particular, the findings suggest a need to broaden our investigations of causal explanations of movement beyond launching (i.e., contact of one object leading to motion of another) to also consider entraining (i.e., joint movement following contact) and pulling. The collected studies provide fertile ground for further testing a variety of mechanisms that explain different perceptual impressions of causality.

Does synchronised singing enhance social bonding more than speaking does? A global experimental Stage 1 Registered Report

Do humans bond more when singing together or speaking together? A global investigation

Recommended by ORCID_LOGO based on reviews by Melissa Brandon, Erin Hannon, Manuela Maria Marin and Anja Göritz
Music is a universal across human cultures, but there is debate as to why and how it evolved. For example, Pinker has famously argued that music is “auditory cheesecake,” with no biological value (Pinker, 1997). Most scholars on the evolution of music make comparisons with language, another human universal that is unique to our species (Friederici, 2017). A current leading hypothesis in the evolution of music is the social bonding hypothesis, which suggests that music plays a special role in social bonding beyond the role that language plays (Savage et al., 2021).
 
Previous studies have provided evidence that synchronized music-making can promote social bonding (e.g. Stupacher et al., 2021). However, it is unclear whether synchronous singing provides any advantage in social bonding as compared to merely speaking. Previous work on this topic has at times lacked sufficient controls and has potentially been subject to publication bias—it could be that only the studies with statistically significant findings are in the published literature, when in fact additional experiments may have been run with unpublished null results. Also critically, prior studies have been subject to sampling bias—the vast majority are limited to a small set of cultures and musical styles, focusing primarily on English-speaking cultures and western music (Henrich & Heine, 2010). If music has evolved as a mechanism for social bonding, then it is especially critical to demonstrate its effects on social bonding across a wide range of cultures.
 
In a remarkable global collaboration including 88 collaborators from six continents, Savage et al. (2025) plan to collect data on synchronized singing and speech from 1710 participants across 57 research sites. Participants will be assigned to participate in (1) a synchronized singing activity, (2) a synchronized speech activity, or (3) a natural, prompted conversation.
 
At each research site, participants will gather in groups of 5-10 and will be randomly assigned to one of the three conditions (for the research site to be valid, it must recruit one group of participants into each condition). The experiment will start with pre-test measures of social bonding and other variables. Next, the intervention will commence. In the singing condition, participants will synchronously sing a song that is highly familiar in that culture. In the lyrics recitation condition, participants will synchronously speak printed lyrics to the songs from the singing condition (twice through, to account for speed differences in song and speech). In the conversation condition, participants will have a natural conversation in response to an ice-breaker question. Finally, each group will engage in post-test measures of social bonding as well as debriefing.
 
The social bonding hypothesis predicts that participants in the synchronized singing task will experience more social bonding (as measured by a pre- and post-test differences) than will participants who engage in sequential conversation or synchronous lyrics recitation in the absence of musical pitch or rhythm. The unprecedented scale of this global, cross-cultural investigation will make a great impact on the field and on our understanding of the relationship among speech, song, and social connection, regardless of the outcome.

Unveiling the Positivity Bias on Social Media: A Registered Experimental Study On Facebook, Instagram, And X

Social media positivity bias, or just positivity bias?

Recommended by ORCID_LOGO based on reviews by Marcel Martončik, Julius Klingelhoefer and 1 anonymous reviewer
Both research and public debates around social media use tend to involve a premise of positivity bias, which refers to presenting one’s life in an overly positive light by various different means. This premise contributes to multiple potentially important follow-up hypotheses, such as the fear of missing out and low self-image effects, due to repeated consumption of positive social media content (e.g., Bayer et al. 2020, for a review). The positivity bias of social media use, itself, has received limited research attention. 
 
In the present study, Masciantonio and colleagues (2025) tested positivity bias in the context of three social media platforms: Facebook, Instagram, and X. The experiment involved recruiting participants (n=312) into platform-specific user groups and crafting posts to be shared with friends as well as respective social media audiences. For social media positivity bias to differ from everyday positivity bias, posts in the former should introduce more positive valence in comparison to offline sharing—and if the platforms differ in their encouragement of positivity bias, they should introduce significant between-platform differences in valence.
 
Based on how the participants reported events, the study found no significant differences between everyday and social media positivity bias, but messages posted on Twitter/X had a more negative valence than posts in other social media platforms. The results would be consistent with the implication that people's positive actions in social media simply follow the natural human tendency to present oneself positively to others—a hypothesis that should be investigated in follow-up work. More research attention should also be given to specific design features, which may contribute to platform-specific differences in user habits, as suggested by the distinct valence rate found in relation to Twitter/X.
 
The Stage 2 manuscript was evaluated by three experts (areas: experimental methods, social media, statistics) via in-depth peer review across two rounds, with one reviewer returning to validate analysis code and methdological accuracy on a final round. Based on the authors’ careful responses and revisions, the revised manuscript was judged to meet the Stage 2 criteria and was awarded a positive recommendation.

See me, judge me, pay me: Gendered effort moralization in work and care

A gender difference in effort moralization?

Recommended by ORCID_LOGO based on reviews by Jared Celniker and Vincent Kouassi
Effort moralization is the well known idea that, unrelated to actual performance, people doing more effort are judged better, attributed more morality and seen as better collaborators than people doing less effort. However, the series of studies on this topic mostly used vignettes with a man or a neutral protagonist. The current study by Roth et al. (2025) proposes to tackle the gender problem by testing the difference in attribution morality between a man and a woman protagonist, and two contexts: a “care” and a “work” context, mirroring the stereotypes associated with men and women.
 
The authors included two different and adequate power analyses, various interpretation of the possible effects, and filtering to ensure a high quality of data collection. They also provide a supplementary repository including the qualtrics survey, R script, and simulated data.

Mapping methodological variation in experience sampling research from design to data analysis: A systematic review

Methodological Variation in the Experience Sampling Methods: Can We Do ESM Better?

Recommended by ORCID_LOGO based on reviews by Priya Silverstein and 1 anonymous reviewer
The replication crisis/credibility revolution has driven a vast number of changes to our research environment (Korbmacher et al., 2023) including a much needed spotlight on issues surrounding measurement (Flake & Fried, 2020). As general understanding and awareness has increased surrounding the 'garden of forking paths' or 'researcher degrees of freedom' (Simmons et al., 2011), and the various decisions made during the scientific process that could impact the conclusions drawn by the process, so too should our interest in meta-research that tells us more about the methodological processes we follow, and how discretionary decisions may influence the design, analysis and reporting of a project.
 
Peeters et al. (2025) have proposed a systematic literature review of this nature, mapping the methodological variation in experience sampling methods (ESM) from the design stage all the way to dissemination. It starts this journey by mapping how ESM studies vary e.g., in design, considering a variety of factors like sample size, number of measurements, and sampling scheme. It also evaluates reporting quality, rationales provided, and captures the extent of open science practices adopted. Covering many parts of the research process that get assumed, unreported or otherwise unjustified, the proposed work looks set to springboard an important body of work that can tell us more effectively how to design, implement and report ESM studies.

Positive Treatment Effects and High Heterogeneity of Hormonal Contraceptive Use on Women's Sexuality

The Causal Effects of Hormonal Contraceptives on Sexuality Outcomes

Recommended by ORCID_LOGO based on reviews by Summer Mengelkoch and 1 anonymous reviewer
Ensuring universal access to sexual and reproductive health and reproductive rights is a global concern, exemplified by goal 5.6 of the Sustainable Development Goals (UN General Assembly, 2015). Whilst the range of contraceptive options have increased, our understanding of the impacts of use for women are inadequate and represent a key barrier to positive change in policies and practices. In particular, we have few consensuses on the expected impacts of hormonal contraceptive use on women's sexuality and wellbeing.
 
In their Stage 1 Report, Botzet et al. (2023) argued that this inconclusive evidence base could be due to the wide heterogeneity in responses, the impacts of this heterogeneity upon attrition, differences in contraceptive methods and dosage effects, confounders, and the potential for reverse causality. Tackling some of these potential factors, Botzet (2023) planned to explore whether hormonal contraceptive use influences sexuality and well-being outcomes, and whether (and to what extent) the effects vary between women. To achieve this they proposed analysis of longitudinal data from the German Family Panel (PAIRFAM) which included annual waves of data collection, with separate Stage 2 submissions planned to report findings based on sexuality and well-being.
 
This specific Stage 2 Report, Botzet et al. (2025) focus upon the sexuality-based outcomes of the programme of work and found positive effects of hormonal contraceptives on sexual frequency and sexual satisfaction (but not desired sexual frequency), having controlled for a number of potential confounding variables. However, they also found relatively high heterogeneity for individual treatment effects, suggesting that predicting its effect for any given individual may be difficult. This work is a rigorous starting point for better understanding the impacts of hormonal contraceptives and the possibility for tailored approaches to contraception. 
 
The Stage 2 manuscript was evaluated following one round of in-depth review. Based on detailed responses to the reviewers' and recommenders' comments, the recommender judged that the manuscript met the Stage 2 criteria and therefore awarded a positive recommendation.
