STAGE 1
Implementing a rapid geographic range expansion - the role of behavior and habitat changesThe role of behavior and habitat availability on species geographic expansionRecommended by Chris Chambers
Note from the PCI RR Managing Board: This Stage 1 recommendation was originally written by Esther Sebastián González for PCI Ecology on 06 Oct 2020 and was transferred to PCI Registered Reports on 14 Jan 2025 to facilitate the submission and evaluation of the resulting Stage 2 submissions. The link to the original recommendation and review history at PCI Ecology may be found at this link (and in PDF format here).
===
Understanding the relative importance of species-specific traits and environmental factors in modulating species distributions is an intriguing question in ecology [1]. Both behavioral flexibility (i.e., the ability to change the behavior in changing circumstances) and habitat availability are known to influence the ability of a species to expand its geographic range [2,3]. However, the role of each factor is context and species dependent and more information is needed to understand how these two factors interact. In this pre-registration, Logan et al. [4] explain how they will use Great-tailed grackles (Quiscalus mexicanus), a species with a flexible behavior and a rapid geographic range expansion, to evaluate the relative role of habitat and behavior as drivers of the species’ expansion [4]. The authors present very clear hypotheses, predicted results and also include alternative predictions. The rationales for all the hypotheses are clearly stated, and the methodology (data and analyses plans) are described with detail. The large amount of information already collected by the authors for the studied species during previous projects warrants the success of this study. It is also remarkable that the authors will make all their data available in a public repository, and that the pre-registration in already stored in GitHub, supporting open access and reproducible science. I agree with the three reviewers of this pre-registration about its value and I think its quality has largely improved during the review process. Thus, I am happy to recommend it and I am looking forward to seeing the results.

Neophobia across social contexts in juvenile Herring gullsHerring gulls exhibit reduced neophobia when tested in groupsRecommended by Ljerka Ostojic based on reviews by Claudia Mettke-Hofmann and 1 anonymous reviewer
How well animals may be able to cope with changes of habitat, specifically with rapid changes and thus novelty they encounter in an environment densely populated by humans, may be influenced by how they respond to novelty in general (Batisteli et al., 2022; Biondi et al., 2024; Castano et al., 2024; Heales et al., 2024). In considering this, it may be important to account for any difference in behavioural responses that animals exhibit when encountering a novel situation alone versus when they are doing so as part of a group.
Here, Allaert et al. (2025) tested how neophobia – the fear of unfamiliar objects – is affected by the social context in gulls, birds that are increasingly forced to live in urban environments due to the loss of natural coastlines. In this study, in which they reared herring gulls from egg and tested them taking into account that nestmates are not tested within the same groups, the authors found that the birds were faster to eat and spent more time in the zone of interest when they were tested in a group than when they were tested individually, specifically when a novel object was placed next to the food compared to when that object was a familiar one. The birds were also faster to enter the testing area when tested in a group, but this was not specific to the novel object condition. In addition to these changes in the average responses, the authors also report reduced variance when tested in a group in two of their three measures, namely in the latency to enter the testing area and time spent in the zone of interest.
The authors interpret their findings as being mostly in line with the ‘risk-dilution’ hypothesis, which is often considered in terms of predation risk (Krause & Buxton, 2002). They discuss possible reasons why other studies, with different species and different methodological setups, found support for alternative explanations.
The Stage 2 report was evaluated by the same two reviewers who had also reviewed the Stage 1 manuscript. In the revision, the authors focused on adding sex as a factor in their statistical models, which was the planned procedure for the statistical analyses in the Stage 1 report, and adding information regarding the problems encountered during testing and how these were handled. This specifically refers to the planned sample size (which the authors planned in the Stage 1 report taking into account both mortality and the fact that some birds would be not herring gulls but lesser black-backed gulls, which can only be established after hatching). However, there was higher than expected mortality, leading to a larger-than-planned overall reduction in sample size. During the study, the authors had contacted the recommender and discussed this issue, and the recommender advised on continuing the study and approved of the planned changes in the Stage 2 report. During the revision process, the authors added more information and also conducted an exploratory analysis, which included all birds, i.e. herring gulls and lesser black-backed gulls. This was suggested by a reviewer and the authors present this exploratory analysis in full in the supplemental material, while the main inferences are presented in the main text. In addition, during the Stage 2 review it became apparent that some minor details regarding the procedure would be useful to be included in the Stage 2 report, which the authors included in the Stage 2 revision. This did not alter the procedure as described in the Stage 1 report, but merely added more clarity to the text.
Based on detailed engagement with these points and the reviewers' comments, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

Action interpretation determines the effects of go/no-go and approach/avoidance actions on food choiceDoes interpretation of actions as either avoid or inhibit influence choice behaviour for candy?Recommended by Andrew Jones based on reviews by Alexander MacLellan and Katrijn HoubenExperimental 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.

Does learning more about others impact liking them?: Replication and extension Registered Report of Norton et al. (2007)’s Lure of AmbiguityRevisiting ‘less is more’: A failure to replicate the association between increased knowing and decreased likingRecommended by Yuki Yamada based on reviews by Philipp Schoenegger and Zoltan Kekecs
Does knowing more about others necessarily lead to greater liking, or might it breed contempt, as suggested by Norton et al. (2007)? In the current study, Horsham et al. (2025) tried to replicate and extend that original question. Collecting data from a large sample of U.S. undergraduates and employing carefully revised designs reviewed at Stage 1, they replicated Norton et al.’s initial studies (1a, 1b, and 2) while also adding new measures. Their primary aim was to see if the “less is more” effect, where increased familiarity decreases liking, would hold under rigorous modern standards, including pre-registration and several open science practices.
Results indicated that people indeed believe they will like someone more if they know more about that person, replicating Norton et al.’s initial finding from Studies 1a and 1b. However, the association between greater knowledge and reduced liking, the core of the “less is more” claim, was not consistently observed. Instead, the data showed little evidence that accumulating information inevitably decreases liking. Moreover, an added examination of curiosity as a potential mediator revealed that although curiosity and liking are positively related, curiosity itself was not strongly contingent on the amount of knowledge participants had. These findings help clarify why previous literature has sometimes presented mixed outcomes, and they underline the distinction between what people predict will happen and what actually does happen in forming impressions of others.
Peer review involved thorough evaluations by experts. Following multiple revisions through Stages 1 and 2, the manuscript has been deemed a carefully executed Registered Report, providing transparent methods, open data, and full reproducibility. It adds nuance to discussions around how knowledge, familiarity, and curiosity jointly shape our interpersonal attitudes. On this basis, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

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 (2025) conducted 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 and age differences.
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 Stage 2 manuscript was evaluated over three rounds of in-depth review. Based on detailed responses to the reviewers’ and recommender’s comments, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

The effect of stimulus saliency on the modulation of ongoing neural oscillations related to thermonociception: a Registered ReportAre there oscillatory markers of pain intensity?Recommended by Zoltan Dienes based on reviews by Markus Ploner and Bjoern Horing
Rhythmic changes in pain can lead to corresponding modulations of EEG amplitudes in theta, alpha, and beta bands. But the question remains open as to whether these modulations are actually tracking pain, or maybe rather saliency or stimulus intensity. The question is of some importance because a marker of pain per se could be useful for tracking felt pain without a verbal response, and could be useful in investigating interventions for treating pain (such as suggestion). Here, Leu et al. (2025) addressed the question of whether modulations reflect saliency or else the intensity of pain, by using an oddball paradigm in which most trials are a pain stimulus of a certain intensity, and oddball trials will sometimes occur, at either a higher intensity or a lower intensity than the baseline ones. If the modulations reflected salience, the modulation at the frequency of the oddball would be similar for high and low intensity oddballs. However, if the modulations reflected pain intensity, the modulations for the low rather than high oddball condition would be lower.
In fact, the baseline and oddball stimulations were found to be perceived significantly differently only in the high oddball condition; and consistantly, the oddballl stimulus significantly modulated ongoing oscillations in only the high oddball condition. Thus, whether oscillations are modulated by pain intensity or salience could not be picked apart in this study. The study does however raise an important isssue, indicate how it could be addressed, and provide data relevant for clearly resolving the issue in the future.
The Stage 2 manuscript was evaluated over two rounds of in-depth peer review. Based on detailed responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 2 criteria for acceptance.

The effects of false feedback on state memory distrust toward commission and omission, and recognition memory errorsExploring how feedback on memory accuracy shifts criteriaRecommended by Zoltan Dienes based on reviews by Dan Wright, Romuald Polczyk, Greg Neil and 1 anonymous reviewer
We may not believe what our memory tells us: Memory may deliver a compelling recollection we believe did not happen (we know we were not there at the time); and we may know an event happened that we fail to remember. That is, there can be distrust in remembering and distrust in forgetting. Previous work by the authors has looked at this through a signal detection lens, reporting in separate studies that people who have distrust in remembering have either a high or low criterion for saying "old" (Zhang et al, 2023, 2024). A plausible explanation for these contrasting results is that the criterion can either be the means by which false memories are generated enabling the distrust (low criterion); or rather, in conditions where accuracy is at stake, the means for compensating for the distrust (high criterion).
In the current study by Zhang et al (2025), participants were incentivised to be as accurate as possible, and in a memory test given feedback about commission errors or, in another group, ommission errors. The manipulation check indicated that the feedback did not increase (by a meaningful amount) distrust in remembering or distrust in forgetting, respectively, compared to a no feedback control group. Nonetheless, the authors found that people adjusted the criterion to say "old" in a compensatory way in each group. The possible mechanisms underlying these criterion shifts are discussed by the authors, who grapple with the distinction between response criterion shifts versus genuine meta-memory belief changes, and for the latter case, whether any memory distrust change could be contextual versus global (the manipulation check measured the latter).
The Stage 2 manuscript was evaluated over one round of in-depth review by four reviewers. Based on detailed responses to the reviewers' and recommender's comments, the recommender judged that the manuscript met the Stage 2 criteria for recommendation.

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 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.
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
The Stage 2 manuscript was evaluated over one round of in-depth review. Based on detailed responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.

Do Ecological Valid Stop Signals Aid Detour Performance? A Comparison of Four Bird SpeciesWhat is the role of sensory perception in cognitive task performance? An improved replication of detour performance in four different bird speciesRecommended by Dieter Lukas 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.

Michotte's research on perceptual impressions of causality: a registered replication studyMichotte’s classic studies on the perception of causality: Replications, extensions and a sound base for further researchRecommended by Moin Syed 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.
