The reward value of a stimulus is based on an error in prediction: Things going better than predicted. Could this learning principle, often tested on short acting stimuli, also apply to a long lasting episode, like going for a run? Could how rewarding a run is be based on the run going better than predicted?

 

Understanding the conditions under which exercise is pleasurable could of course be relevant to tempting people to do more of it! In the current study, Brevers et al. (2024) asked people before a daily run to predict the amount of perceived exertion they would experience; then just after the run, to rate the retrospective amount of perceived exertion actually experienced. The difference between the two ratings was the prediction error. Participants also rated their remembered pleasure in running. As hypothesized, the authors found that running pleasure increased linearly with how much retrospective exertion was than predicted.
 
The Stage 2 manuscript received one round of review from two external reviewers, then some minor comments from the recommender, after which it was judged to satisfy the Stage 2 criteria and was awarded a positive recommendation.

The debate about consciousness and its neural underpinnings is a hot topic in cognitive neuroscience that has driven innovative original research and theoretical frameworks (Dehaene et al., 2006; Lamme, 2006). Consciousness itself can be defined and studied from different perspectives, such as neuropsychology (Laureys et al., 2004; Monti, 2012), applied philosophy (Blanke & Metzinger, 2009), and experimental cognitive neuroscience (Dehaene & Changeux, 2011). However, after several decades of research via different methods and from different perspectives, basic questions regarding consciousness and its neural underpinnings are still debated (Chalmers, 2010). One of the reasons for this ongoing debate is that consciousness cannot be easily disentangled from confounds, such as involvement of other cognitive processes like memory, language, and so forth (Dehaene & Changeux, 2011).

 

In the current study, Colombari et al. (2025) focus on disentangling neural markers of conscious visual perception from motoric responses. To this end, the study uses a cutting-edge neuroimaging technique, Event-Related Optical Signal (EROS), to measure the neural responses during a Go/No-Go detection task, which is especially designed to gauge visual perception regardless of response production. The study, therefore, is instrumental in addressing the neural foundation of conscious visual perception and is well situated to advance our understanding of consciousness and its neural underpinnings.

Open science practices (OSPs, e.g., preregistration, open materials, code and data) aim to enhance the transparency, integrity, and reproducibility of research. Recent work, however, has highlighted various facilitators and barriers perceived by researchers in implementing these, which can either enhance or hinder their success. Little is known about these barriers in the context of Slovakia, and such perceptions are rarely investigated for policy makers and media representatives who are also embedded in the research ecosystem.

 

In their Stage 1 Registered Report, Marcel Martončik and colleagues aim to map the perceptions and experiences of barriers and facilitators of OSPs that are unique to different stakeholder groups in Slovakia. They will conduct both semi-structured interviews and focus groups with a diverse sample of postgraduate students, researchers, policymakers, and media representatives from the field of psychology. Reflexive thematic analysis will identify overarching themes regarding such barriers and facilitators which will provide valuable insights into the support required to make OSPs normative across different stakeholder groups.

 

Four expert reviewers assessed the Stage 1 manuscript across two rounds of in-depth review. Based on the authors' detailed and informed responses to the reviewer’s comments, the recommender judged that the manuscript met the Stage 1 criteria and awarded in principle acceptance (IPA).

Surveys that measure self-report are a workhorse in psychology and the social sciences, providing a vital window into beliefs, attitudes and emotions, both at the level of groups and individuals. The validity of self-report data, however, is an enduring methodological concern, with self-reports vulnerable to a range of response biases, including (among others) the risk of social desirability bias in which, rather than responding honestly, participants answer questions in a way that they believe will be viewed favourably by others. One proposed solution to socially desirable responding is the so-called Bayesian Truth Serum (BTS), which aims to incentivise truthfulness by taking into account the relationship between an individual’s response and their belief about the dominant (or most likely) response given by other people, and then assigning a high truthfulness score to answers that are surprisingly common.

 

Although valid in theory (under a variety of assumptions), questions remain regarding the empirical utility of the BTS. One area of concern is participants’ uncertainty regarding incentives for truth-telling – if participants don’t understand the extent to which telling the truth is in their own interests (or they don’t believe that it matters) then the validity of the BTS is undermined. In the current study, Neville and Williams (2024) aim to test the role of clarifying incentives, particularly for addressing social desirability bias when answering sensitive questions. The authors will administer an experimental survey design including sensitive questions, curated from validated scales, that are relevant to current social attitudes and sensitivities (e.g. “Men are not particularly discriminated against”, “Younger people are usually more productive than older people at their jobs”). Three groups of participants will complete the survey under different incentive conditions: the BTS delivered alone in standard format, the BTS with an interim bonus payment that is awarded to participants (based on their BTS score) half-way through the survey to increase certainty in incentives, and a Regular Incentive control group in which participants receive payment without additional incentives.

 

The authors will then address two questions: whether the BTS overall effectively incentivises honesty (the contrast of BTS alone + BTS with interim payment vs the Regular Incentive group), and whether interim payments, specifically, further boost assumed honesty (the contrast of BTS alone vs BTS with interim payment). Regardless of how the results turn out, the study promises to shed light on the effectiveness of the BTS and its dependence on the visibility of incentives, with implications for survey design in psychology and beyond.

Measuring people’s experiences, thoughts, and mental processes has always been a core challenge of psychological science (e.g. Nisbett & Wilson 1977). When such measurement relates to rapidly changing and conceptually diverse human-technology interactions, the task becomes even more difficult due to protean, multidimensional constructs. A good understanding of a construct is a basic step in its measurement (Borsboom 2005).  
 
In the present registered report—carried out as part of a long-term measure development project—Dunne et al. (2024) carried out a focus group study with adolescents (n=26) aged 11 to 15 in Northwest England to improve the understanding of constructs related to social media and mental health. The authors applied reflexive thematic analysis to explore adolescents’ social media use experiences and related motivations in the light of mental health.
 
The data and research process led to a construction of five themes, which were connected to mental health in direct and indirect ways. The participants voiced direct experiences of anxiety, self-esteem, and social aspects that reflect a mental health network where social media play diverse roles. Indirect implications of coping and self-control were found to supplement the network. Taken together, the themes and their implications to wellbeing make a valuable contribution to the evolving qualitative understanding young people's social media use in the UK (e.g., Conroy et al. 2023) and serve as a useful basis for future measure development.
 
A particular strength of the work was the engagement of three Young Researchers who co-facilitated the focus groups and were involved in the analysis. The research meets high reflexivity and transparency criteria, and the carefully constructed supplementary materials provide informative details especially for measure developers. Finally, the authors must be commended for sharing these valuable data for reuse.
 
The Stage 2 manuscript was reviewed over two rounds by three unique reviewers. The reviewers’ expertise ranged from social media and technology use research to health psychology and qualitative methods. Based on careful revisions and detailed responses to the reviewers’ comments, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.
