Progression of white matter hyperintensities is related to blood pressure increases and global cognitive decline – a registered reportWhite matter lessions are associated with increases in blood pressure and global cognitive declineRecommended by Chris Chambers based on reviews by Isabel Garcia Garcia
Cerebral small vessel disease (CSVD) is a common and multi-faceted set of pathologies that affect the small arteries, arterioles, venules and capillaries of the brain. The disease manifests through a range of symptoms and conditions, including psychiatric disorders, abnormal gait, and urinary incontinence, while accounting for 25% of strokes and nearly 50% of dementia.
The presence of CSVD is associated with white matter lesions detected as white matter hyperintensities (WMH) using neuroimaging, which have in turn been shown to predict future stroke, cognitive decline and dementia. While vascular risk factors of CSVD (such as hypertension and obesity) are also associated with CSVD, a complete picture of the predictive relationship between WMH, cognitive decline, and blood pressure remains to be determined, as does the role of sex/gender. These inter-relationships are important to determine for improving the diagnosis and treatment of CSVD.
In the current study, Beyer et al. analysed a large emerging dataset from the LIFE-Adult project – a longitudinal, two-wave, population-based study – to ask whether higher blood pressure predicts a greater increase in WMH, and whether progression of WMH is associated with measures of memory and executive function. In addition, the authors explored the relationship between abdominal obesity and WMH progression, and the extent to which WMH progression, and its interaction with vascular risk factors, depends on sex/gender.
Results revealed no reliable association between baseline blood pressure with WMH progression. WMH progression significantly predicted global cognitive decline but not decline in executive function specifically. Exploratory analyses revealed that increases in diastolic blood pressure as well as baseline and systolic blood pressure were associated with WMH progression, specifically in frontal periventricular regions, but there was no association of waist-to-hip ratio (a proxy of abdominal fat deposits) with WMH progression nor any gender-specific associations. The authors conclude that strict control of blood pressure might confer a protective effect, limiting WMH progression and negative effects on global cognitive function in the middle-aged to older population.

STAGE 1
Reading and vocabulary knowledge in English-Meetei Mayek biliteratesDiversifying our understanding of children’s word learningRecommended by Moin Syed based on reviews by Maxine Schaefer and 1 anonymous reviewer
The positive relation between word reading and children’s vocabulary development has been extensively documented. That said, like most research in psychology and the behavioral sciences, the available evidence comes predominantly from majority populations. In the context of language learning, that means monolingual speakers or multilingual speakers where there is close alignment between home and school language learning. But what does the relation between word learning and vocabulary knowledge look like when the learning contexts are discordant?
In the current study, Pamei et al. (2024) propose to examine this question by investigating word learning and vocabulary development in two languages, English and Meetei Mayek, among a sample of Grade 3 (approximate age 10), students in Manipur, India. In this context, formal literacy education begins in English rather than in students’ regional home language of Meetei Mayek. This fact provides an innovative context in which to understand how a) whether the relation between word reading and vocabulary looks different in the two languages, and b) whether there is linguistic interdependence between learning in the two languages. This study is poised to bring important underrepresented data that goes beyond the dominant contexts from which our knowledge of language learning has been generated, and thus has the potential to contribute to new lines of empirical and theoretical work that is inclusive of global variations.

Sight vs. sound in the judgment of music performance: Cross-cultural evidence from classical piano and Tsugaru shamisen competitionsUnderstanding the role of visual and auditory information in evaluating musical performanceRecommended by Yuki Yamada based on reviews by David Hughes and Kyoshiro Sasaki
In this Stage 1 Registered Report, Chiba and colleagues (2021) aim to investigate how people use information from visual and auditory modalities when evaluating musical performances. Previous studies, mainly using Western music, have reported a visual dominance, but this has not yet been clearly and consistently reported. Thus, the authors propose to evaluate both the reproducibility and generalizability of the previous findings by conducting a replication study using the methodology of the previous studies and by introducing a new experimental condition in which the Tsugaru-shamisen, a unique Japanese musical instrument, is also performed. This study could represent an important turning point in the research context of performance evaluation and would be of considerable value. This manuscript was peer-reviewed by two experts in scientific methodology and Japanese traditional music, respectively, and during the two-round peer-review process they made a number of important points, but eventually awarded the manuscript a highly positive response. I am therefore pleased to recommend that this Stage 1 Registered Report meets our Stage 1 criteria and is worthy of in-principle acceptance. I look forward to seeing the results and discussion reported in Stage 2, with the expectation that the experiment conducted by the authors will be in strict accordance with this protocol. *The following is a very minor comment, which I hope the authors will find helpful in the future. Of course, this is not related to hypothesis construction and does not require revision: The "Blind Audition" study cited in the introduction is very impactful, but has recently been called into question, so I am at least a little cautious when citing this study.

Sight vs. sound judgments of music performance depend on relative performer quality: Cross-cultural evidence from classical piano and Tsugaru shamisen competitions [Stage 2 Registered Report]Music is appreciated cross-modally, but is culture- and context-dependentRecommended by Yuki Yamada based on reviews by Kyoshiro Sasaki and 1 anonymous reviewer
Music is not merely limited to the aural experience we garner through our auditory faculties, as commonly perceived. Rather, various studies have explored the cross-modal impact of visual stimuli on the evaluation of music. These previous studies have been confined exclusively to Western music. Hence, Chiba et al. (2023) designed a study with a focus on the Tsugaru shamisen, a renowned folk instrument indigenous to Japan, and of which the first author is an outstanding player.
The study methodology was an improved version of previous endeavors, wherein actual musical material sourced from concours performances was displayed through audio-only, video-only or both modalities. A sample of Japanese participants were then asked to evaluate the concours performances on both the piano and the Tsugaru shamisen. The results, obtained through pre-registered protocols, revealed that for both concours performances, the participants displayed a cross-modal impact of visual information on their aural evaluation of music. This effect was also found to be contingent on cultural and contextual factors. These outcomes furnish valuable evidence towards the generalizability of the interplay between sight and sound in the assessment of music. The study underwent rigorous peer-review processes in both Stage 1 and Stage 2, with three experts specializing in Japanese folk music, open science, and statistics, respectively, providing their critical assessments. Following multiple rounds of revision, the final manuscript was deemed fit for recommendation.

Dose-response of tDCS effects on motor learning and cortical excitability: a preregistered studyHow stimulation intensity affects motor learningRecommended by Christina Artemenko based on reviews by Charlotte Wiltshire and 1 anonymous reviewer
In neurostimulation research, the parameters of a stimulation protocol crucially impact on the effects of the stimulation. Transcranial direct current stimulation (tDCS) is a neurostimulation technique that typically uses current intensities about 1-2 mA in human research to modulate motor and cognitive behavior. The current sham-controlled study by Hsu et al. (2024) applies current intensities not only of 2 mA but also of 4 mA and 6 mA and thus extends our understanding of stimulation parameters while ethical standards are preserved.
The influence of tDCS over the primary motor cortex will be evaluated for neural plasticity during motor learning. Stimulation effects will be tested not only behaviorally but also physiologically by motor evoked potentials elicited by transcranial magnetic stimulation (TMS). The presented pilot data are promising and underline the feasibility of the proposed research design. The study will contribute to tDCS research by uncovering reasons for controversial findings and thus increase reproducibility.

Dose-response of tDCS effects on motor learning and cortical excitability: a preregistered studyIncreasing stimulation intensity does not affect motor learningRecommended by Christina Artemenko based on reviews by 1 anonymous reviewer

The study contributes to tDCS research by uncovering reasons for controversial findings and thus increases reproducibility.
The results of the study unexpectedly revealed no stimulation effects on motor learning, neither for behavioral outcomes nor for physiological outcomes by motor evoked potentials. No evidence was found that stimulation effects linearly increase with increasing intensity. Interestingly, higher intensities were relatively well tolerated - but did not have any impact. The current findings underline the purpose of preregistrations and registered reports to act against publication bias, particulary in the field of neuromodulation. In the current case, failed replication and null findings - revealed by a methodologically sound study - are crucial to inform future research using similar stimulation protocols with the aim to modulate motor or cognitive behavior.

Arithmetic deficits in Parkinson's Disease? A registered reportGetting the numbers right in Parkinson's disease?Recommended by Zoltan Dienes based on reviews by Pia Rotshtein, Ann Dowker, Stephanie Rossit and 1 anonymous reviewer
Everyday life, including for patients taking different types of medicine, involves dealing with numbers. Even though Parkinson's disease may ordinarily be thought of as primarily being a motor disorder, there is evidence that numerical abilities decline as Parkinson's disease progresses. Further, the brain areas involved in arithmetic operations overlap with the areas that degenerate in Parkinson's disease. In this Stage 1 Registered Report, Loenneker et al. (2022) will test healthy controls, Parkinson disease patients with normal cognition, and Parkinson disease patients with mild cognitive impairment on general working memory tasks as well as arithmetic performance on the four basic operations (addition, subtraction, multiplication, division). The study aims to test whether or not there is a deficit in each operation, and the relation of any deficits to general working memory capacity. The Stage 1 manuscript was evaluated over four rounds of review (including two rounds of in-depth specialist review). Based on comprehensive responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).

Attraction depending on the level of abstraction of the character descriptionsDoes reducing abstractness increase attraction? A test of Uncertainty Reduction TheoryRecommended by Chris Chambers based on reviews by Zoltan Dienes and Florian Pargent
What determines levels of interpersonal attraction? A long history of research in social psychology has highlighted a range of important factors, such as physical attractiveness, similarity of attitudes and beliefs, reciprocity of feelings, self-disclosure of personal information, and familiarity. One theme that runs through several of these characteristics is the concept of uncertainty, and in particular how reducing uncertainty in knowledge about a person influences levels of attraction. According to the Uncertainty Reduction Theory (URT), as an individual’s uncertainty in a person diminishes, levels of attraction are expected to rise. Previous research, however, has reported a mixed and somewhat complicated relationship between uncertainty and attraction, possibly moderated by the current stage of the interpersonal relationship.
One limitation of this area of enquiry is that the methods used to reduce uncertainty have tended to focus on the amount of available information rather than its quality. This shortcoming has become increasingly salient with the rise of online social networking, where people have a wide range of strategies available to reduce uncertainty through passive (non-interactive) observation, for instance by studying profile details or other online information about a person. In the current study, Kuge et al. (2024) aim to partially fill this gap by examining the role of uncertainty reduction by altering the abstractness (or specificity) of available information, rather than its quantity, particularly in an observational, non-interactive setting. According to the tenets of URT, the authors predict firstly that participants will rate a person described in more concrete terms as more attractive than one described using abstract terms, and secondly that perceived uncertainty will mediate the effect of the abstractness on levels of attraction.
To test these hypotheses, the authors begin with an online survey (N=250) to select pairs of sentences with varying levels of abstractness while ensuring they are matched for favourability. Then in the main study (N=1000) they will test the effect of the selected abstract vs. concrete expressions on levels of attractiveness, in addition to control variables such as how confident the participant is in predicting the person’s behaviour, as well as a manipulation check to confirm the effectiveness of the abstractness manipulation. Confirmation of these hypotheses would add support for URT, while disconfirmation may indicate that the theory is inadequate at explaining the drivers of attraction in online unilateral communication.

Representativeness heuristic in intuitive predictions: Replication Registered Report of problems reviewed in Kahneman and Tversky (1973)The Representativeness Heuristic Revisited: Registered Replication Report of Kahneman and Tversky (1973)Recommended by Rima-Maria Rahal based on reviews by Peter Anthony White, Regis Kakinohana and Naseem Dillman-Hasso
Revisiting a true classic, this registered replication report addresses Kahneman and Tversky’s (1973) introduction of the representativeness heuristic. The heuristic refers to deviations of judgments from normative evaluations of the evidence when the stimulus fits to a prototype. For instance, when an individual is described by features stereotypically associated with a certain target group (e.g., a person who attends dance training several times a week and has a passion for singing and performing), likelihood judgments that the individual belongs to a target group (K-Pop artists) compared to a non-target group (e.g., accountants) are inflated.
The impact of the original research on the field is clearly immense and long-lasting. All the better that a systematic replication attempt is being undertaken in this registered report, which addresses studies 1 through 7 of Kahneman and Tversky’s classic 1973 paper. Chan and Feldman (2024) propose a well-powered online study, in which all studies from the original article are presented to participants within-subjects. The materials are carefully constructed and closely documented in the accompanying OSF project, where in-depth information on planned data analyses is supported with a simulated dataset. The Stage 1 manuscript was evaluated over three rounds of in-depth review. Based on detailed responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA). URL to the preregistered Stage 1 protocol: https://osf.io/er2cq
Level of bias control achieved: Level 6. Data collection commenced during the later part of Stage 1 peer review; however, since no substantive changes to the design were made after this point, the risk of bias due to prior data observation remains zero and the manuscript therefore qualifies for Level 6.

The capacity of response training to help resist the consumption of sugary drinksGamified response training with sugary drinks does not facilitate adherence to a restrictive dietRecommended by Zhang Chen based on reviews by Matthias Aulbach and Pieter Van Dessel
Many people nowadays struggle with maintaining a healthy diet. Despite the intentions to eat healthily, they often over-consume highly palatable yet nutrient-poor foods and drinks, which in turn can lead to many health problems. There is therefore a need to develop tools that can help people resist the (over-)consumption of such foods and drinks.
Previous work has shown that training people to execute certain motor responses toward food items can modify their liking for these items, which may also influence their subsequent consumption behavior. Based on these findings, Najberg et al. (2023) developed a mobile game that combined two food-related response training tasks, namely the go/no-go training (Veling et al., 2017) and the cue-approach training (Schonberg et al., 2014). The experimental group was trained to consistently inhibit their responses toward sugary drinks in the go/no-go training, and consistently respond to water items in the cue-approach training (i.e., 100% consistent mapping). In the control group, the mapping between an item and response requirement was 50%, such that participants executed both go and no-go responses toward sugary drinks and water. Najberg et al. (2023) found that after the training, the experimental group reported more reduction in liking for sugary drinks and more increase in liking for water items compared to the control group. However, both groups showed equivalent reduction in self-reported consumption of sugary drinks. Using the same design (i.e., 100% vs. 50% consistency), in the current study, Najberg et al. (2024) further examined whether the combined go/no-go and cue-approach training game could help people resist the consumption of sugary drinks. Participants were divided into the experimental and control group (N = 100 and 92, respectively), and received the respective training for a minimum of seven days (and up to 20 days). After completing the training, they were asked to avoid the trained sugary drinks. The number of days in which they reported to successfully adhere to this restrictive diet was used as the main dependent variable. Contrary to their predictions, the two groups did not differ in how long they resisted the consumption of sugary drinks after training. Both groups showed equivalent reductions in liking for sugary drinks (contrary to the finding in Najberg et al., 2023), but this reduction in liking was not correlated with the number of successful days of diet in the experimental group. Lastly, those who trained for more days in the experimental group also adhered to the diet for a longer duration, but this correlation might be explained by differences in motivation across individuals. Together, these results suggest that consistently withholding responses toward sugary drinks and responding to water items does not help people resist the consumption of sugary drinks, compared to a control intervention in which the mapping is 50%. More research is therefore needed to test the effectiveness of food-related response training in changing consumption behavior outside of laboratory contexts.
