Convenience Samples and Measurement Equivalence in Replication Research

Does data from students and crowdsourced online platforms measure the same thing? Determining the external validity of combining data from these two types of subjects

Recommended by ORCID_LOGO based on reviews by Benjamin Farrar and Shinichi Nakagawa
Comparative research is how evidence is generated to support or refute broad hypotheses (e.g., Pagel 1999). However, the foundations of such research must be solid if one is to arrive at the correct conclusions. Determining the external validity (the generalizability across situations/individuals/populations) of the building blocks of comparative data sets allows one to place appropriate caveats around the robustness of their conclusions (Steckler & McLeroy 2008).
 
In this registered report, Alley and colleagues plan to tackle the external validity of comparative research that relies on subjects who are either university students or participating in experiments via an online platform (Alley et al. 2023). They will determine whether data from these two types of subjects have measurement equivalence - whether the same trait is measured in the same way across groups. Although they use data from studies involved in the Many Labs replication project to evaluate this question, their results will be of crucial importance to other comparative researchers whose data are generated from these two sources (students and online crowdsourcing). If Alley and colleagues show that these two types of subjects have measurement equivalence, then this indicates that it is more likely that equivalence could hold for other studies relying on these type of subjects as well. If measurement equivalence is not found, then it is a warning to others to evaluate their experimental design to improve validity. In either case, it gives researchers a way to test measurement equivalence for themselves because the code is well annotated and openly available for others to use.

The Stage 1 manuscript was evaluated over two 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).

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-dependent

Recommended by ORCID_LOGO 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.

One and only SNARC? A Registered Report on the SNARC Effect’s Range Dependency

Is the SNARC effect modulated by absolute number magnitude?

Recommended by ORCID_LOGO based on reviews by Melinda Mende and 1 anonymous reviewer
The Spatial-Numerical Association of Response Codes (SNARC) effect refers to the fact that smaller numbers receive faster responses with the left hand, and larger numbers with the right hand (Dehaene et al., 1993). This robust finding implies that numbers are associated with space, being represented on a mental number line that progresses from left to right. The SNARC effect is held to depend on relative number magnitude, with the mental number line dynamically adjusting to the numerical range used in a given context. This characterisation is based on significant effects of relative number magnitude, with no significant influence of absolute number magnitude. However, a failure to reject the null hypothesis, within the standard frequentist statistical framework, is not firm evidence for the absence of an effect. In this Stage 1 Registered Report, Roth and colleagues (2023) propose two experiments adapted from Dahaene’s (1993) original methods, with a Bayesian statistical approach to confirm—or rule out—a small effect (d = 0.15) of absolute number magnitude in modulating the classic SNARC effect.
 
The study plan was refined across two rounds of review, with input from two external reviewers and the recommender, after which it was judged to satisfy the Stage 1 criteria for in-principle acceptance (IPA).

Hormonal Contraceptive Use and Women’s Sexuality and Well-Being: Estimating Treatment Effects and Their Heterogeneity Based on Longitudinal Data

The Causal Effects of Hormonal Contraceptives on Psychological Outcomes

Recommended by ORCID_LOGO based on reviews by Summer Mengelkoch and 2 anonymous reviewers
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 the current programmatic submission, Botzet et al. (2023) argue 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) 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 have proposed analysis of longitudinal data from the German Family Panel (PAIRFAM) which includes annual waves of data collection from >6500 women, with separate Stage 2 submissions planned to report findings based on sexuality and well-being. The proposed work will progress our understanding of the impact of hormonal contraceptives by overcoming limitations of more common research approaches in this field, and has the potential to contribute to a more contextualised view of the impact of their impacts in real-world practice.

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 2 anonymous reviewers
The detour task, where an individual has to navigate 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 but blocked reward, the cognitive underpinnings of this behaviour are as yet not fully understood. In the current study, Dewulf et al. (2023) propose to assess one of the specific cognitive processes that might be involved in this behaviour. Through experimental procedures, they will compare the role of signal detection in inhibitory response performance in a detour task. To assess whether variation in detection of the barrier might be linked to the ecological niche of a species, they will compare four bird species who live in different environments. Individuals from these four species were previously tested in a detour task (Regolin et al. 1994, Zucca et al. 2005), and the proposed research plan therefore also involves a partial replication of previous studies on the same issue, but improving some critical aspects.

Voice preferences across contrasting singing and speaking styles

Exploring the enjoyment of voices

Recommended by ORCID_LOGO based on reviews by Patrick Savage, Christina Vanden Bosch der Nederlanden, Christina Krumpholz and 1 anonymous reviewer
Beyond the semantics communicated by speech, human vocalisations can convey a wealth of non-verbal information, including the speaker’s identity, body size, shape, health, age, intentions, emotional state, and personality characteristics. While much has been studied about the neurocognitive basis of voice processing and perception, the richness of vocalisations leaves open fundamental questions about the aesthetics of (and across) song and speech, including which factors determine our preference (liking) for different vocal styles.
 
In the current study, Bruder et al. (2024) examine the characteristics that determine the enjoyment of voices in different contexts and the extent to which these preferences are shared across different types of vocalisation. Sixty participants will report their degree of liking across a validated stimulus set of naturalistic and controlled vocal performances by female singers performing different melody excerpts as a lullaby, as a pop song and as opera aria, as well as reading the corresponding lyrics aloud as if speaking to an adult audience or to an infant. The authors will then ask two main questions: first if there is a difference in the amount of shared taste (interrater agreement) across contrasting vocal styles, and second, as suggested by sexual selection accounts of voice attractiveness, whether the same performers are preferred across styles.

Causal evidence for the role of the sensory visual cortex in visual short-term memory maintenance

The visual cortex can maintain information for up to a second

Recommended by ORCID_LOGO based on reviews by Evie Vergauwe and Vincent van de Ven
According to the sensory recruitment framework, the visual cortex is at least in part responsible for maintaining information about elementary visual features in visual short term memory. Could an early visual area, constantly taking in new information, really be responsible for holding information for up to a second? But conversely, could higher order regions, such as frontal regions, really hold subtle sensory distinctions? It must be done somewhere. Yet the existing evidence is conflicting. Phylactou et al. addressed this question by applying transcranial magnetic stimulation (TMS) to disrupt early visual areas at intervals up to a second after stimulus presentation to determine the effect on visual short term memory performance. In this way, they causally influenced the sensory cortex at relevant times while tightening up on possible confounds in earlier research.
 
They found that TMS applied to the occipital hemisphere at each of 200ms and 1000ms after presentation of a brief visual stimulus disrupted stimuls detection on a visual short term memory test. These findings support sensory recruitment, which claims that both perceptual and memory processes rely on the same neural substrates in the visual cortex.

The Stage 2 manuscript was evaluated by two expert reviewers. Based on detailed responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 2 criteria for recommendation.

Optimizing Esports Performance Using a Synergistic Mindsets Intervention

Synergistic Mindset Intervention for Competitive Situations

Recommended by ORCID_LOGO based on reviews by Lee Moore, Ivan Ropovik , Ivana Piterová and Jacob Keech
Mindset theories suggest that the mere belief in the malleability of human abilities can already help one to develop related performance. On the other hand, one and the same performance situation can also be experienced in various affective ways, which differently contribute to performance outcomes. Arguably, appraising a performance situation as a “threat” instead of “challenge” is associated with maladaptive responses, such as impaired cardiovascular mobilization. If people could experience performance situations as positive challenges, this might also improve performance outcomes. Drawing from these connected theoretical premises, the synergistic mindset intervention was developed and tentatively found to help adolescents in stressful situations (Yeager et al., 2022).
 
In the present registered report, Behnke et al. (2023) build on the above and test whether the synergistic mindset intervention can help individuals in competitive gaming situations. The authors utilize one of the leading esport games, Counter-Strike: Global Offensive​, and recruit its active players into randomized control and intervention groups for two weeks. Ultimately, the participants compete in a cash-prize tournament involving measures of affective experience and cardiovascular responses. Behnke et al. (2023) hypothesize that the synergistic mindset group will show greater challenge affective responses and superior performance outcomes. As such, the study design has significant potential to generate valuable evidence for various theoretical models and the synergistic mindset model in particular.

Stage 2 Registered Report: Stress regulation via being in nature and social support in adults, a meta-analysis

Does emotional support and being in nature influence stress?

Recommended by ORCID_LOGO based on reviews by Felix Schönbrodt and Siu Kit Yeung
Stress is a familiar presence in modern life and may be rising in severity (Almeida et al., 2020). As a key driver of many health problems, controlling stress and its impacts is a central goal in clinical and health psychology, yet the effectiveness of existing interventions to regulate stress remains unclear. 
 
In the current study, Sparacio et al tackled this question from a meta-analytic perspective, focusing on a corpus of existing research that has addressed the efficacy of two specific stress regulation interventions: being in nature and emotional social support. As well as evaluating the evidential content of the relevant literatures, the authors also examined signs of publication bias and the moderating role of personality traits.
 
After correcting for publication bias, the results reveal evidence that being in nature is effective at reducing stress while emotional social support is not. The moderating role of personality for both interventions was inconclusive due to lack of evidence. In addition, the quality of the surveyed literature was found to be low overall, suffering from a high risk of bias and high rate of statistical reporting errors. The authors offer several recommendations to improve the rigour and quality of studies in this field, including open data, open materials, code review, preregistration and the use of Registered Reports.
 
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.

How does the phrasing of house edge information affect gamblers’ perceptions and level of understanding? A Registered Report

Does relaying ‘house edge’ information influence gambler’s perceived chances of winning and their factual understanding of the statistical outcomes?

Recommended by ORCID_LOGO based on reviews by Zhang Chen and Graeme Knibb
Many products that can impact upon health and wellbeing (e.g., alcohol, food) relay information to consumers about the potential risks. However, such information is commonly provided in suboptimal format for gambling-related products. To encourage safer gambling, research has therefore recommended that information about the average loss from a gambling product (“house edge”) or percentage payout (“return-to-player”) should be communicated, with the former translating to better perceived understanding by gamblers. This Registered Report aimed to experimentally compare two phrasings of the house edge against a control return-to-player to arrive at the most effective phrasing to aid gambler’s perceived chances of winning and their factual understanding of the statistical outcomes of their bet. Using a hypothetical gambling scenario, a sample of 3,333 UK-based online gamblers received one of three phrasings: an original house-edge (“his game keeps 10% of all money bet on average”), an alternative house-edge (“on average this game is programmed to cost you 10% of your stake on each bet”) or return-to-player (“this game has an average percentage payout of 90%”). Two outcome measures were employed to judge the effectiveness of this information: gamblers’ perceived changes of winning and factual understanding. The findings indicate that the two-house edge formats were more effective in communicating gambling-related harms than the return-to-player format, but the original house edge phrasing appeared to be the most optimal as it decreased gambler’s perceived chances of winning and increased their factual understanding compared to return-to-player. These results can therefore inform public health policies to reduce gambling-related harm by presenting the most effective communication of gambling risk.
 
After two in-depth reviews, the recommender judged that the manuscript met the Stage 2 criteria and awarded a positive recommendation.
