We conducted the first systematic intercultural comparison of the Intergroup Sensitivity Effect (ISE). In a 2 × 2 within-participants design, participants from three countries representative of individualism (Canada), collectivism (China) and honour/face (Japan) responded to four critical comments (a) about their own culture or another culture and (b) by a commenter from the same or another culture. Participants responded to each comment on established self-report scales and could punish the commenter, at a cost to themselves. Finally, participants reported potential moderators and demographic information. We report robustness checks and detailed data descriptors to facilitate secondary analyses and follow-up studies.

This paper presents datasets for a research project that investigated the individual and combined effects of two perceptual cues-spacing and color-under varying conditions of congruence with the order of operations. The datasets contain 1,100 6th-grade students' data collected through a randomized controlled trial conducted in 2024 in a U.S. school district. All de-identified intervention data are openly available on the Open Science Framework. Additional datasets, including student demographics and assessment data, require a data sharing agreement. The data can be used by researchers interested in understanding perceptual learning mechanisms and improving online instructional materials for middle school mathematics.

This article presents a free association database containing responses to 62 stimulus words (including colour terms, emotion words, and common nouns) across seven languages: English, Estonian, French, German, Italian, Lithuanian, and Spanish. Data were collected online from 1,439 participants (mean age 31.47 years) across 14 countries, yielding 223,786 responses. All data were cleaned, normalised, and organised for analysis, with both raw and processed datasets available on OSF. This cross-linguistic resource enables research on semantic networks, psycholinguistics, translation studies, and cross-cultural comparisons, providing insights into how meaning is constructed within and across different languages and cultures.

This paper describes a longitudinal dataset of perceived job stress, perceived general stress, financial stress, demographics, and educational center characteristics of center-based early childhood educators in the Midwest across the academic year 2021-2022. At four time points, a convenience sample of 67 educators completed electronic surveys. At the first two time points, a subset provided hair cortisol samples to estimate physiological chronic stress. The publicly available, de-identified data can provide nuanced research and teaching opportunities into educators' stressors during a dynamic period of the COVID-19 pandemic.

The MTurk Parent eHealth Preference Survey aimed to examine parents' preferences for eHealth program features as well as their attitudes and preferences towards three programs: AbilitiCBT, Triple P Online, and BEAM. The data also cover sociodemographic factors, mental illness symptoms, social support, resilience, stressful experiences, medication use, and psychosocial service use. The data (n = 177; United States) were collected through an online cross-sectional self-report survey on MTurk. The primary and processed data are available OSF and have reuse potential for clinical research on parental mental health, methodological research on crowdsourcing for participant recruitment, and for use in statistics courses.

This paper introduces a dataset from a validation study of two psychometric models, one on the intraindividual speed-ability relationship and the other one on persistence. It includes responses, response times, and action sequences from N = 1244 participants who completed a matrix reasoning test under two experimental conditions, one being speeded and one being non-speeded. Additionally, it includes measures on motivational disposition, current motivation, effort, and concentration. Collected online via Prolific, the data is freely available at OSF (https://osf.io/9j6hm/). This dataset may aid in the development and validation of psychometric models on response processes as well as the investigation of test-taking behavior.

To assess the feasibility of web probing in India, we conducted a study with different probing questions and a survey experiment in India and the US on the topic of environmental concern. The survey was available in English in both countries and in Hindi in India. The data was collected from December 2022 until May 2023 using the crowdsourcing platform Amazon MTurk. This resulted in 512 respondents from the US and 740 from India (English: 387 respondents, Hindi: 353 respondents). The data provides crucial insights into the performance of web probing outside the Western context and the comparability of measures of environmental concern.

Although the mathematics anxiety-performance link has been extensively studied, its interplay with other emotional and attitude constructs is still unclear. The present dataset includes measures of mathematics anxiety and arithmetic performance alongside different types of anxiety (i.e., state, test, general anxiety and neuroticism), attitudes towards mathematics (i.e., mathematics self-concept, mathematics self-efficacy and mathematics-gender stereotype endorsement), and math-unrelated constructs among university students (N = 848) and primary school teachers (N = 258) from Germany and Belgium. The data is accessible in the Open Science Framework (https://osf.io/gszpb/).

This data file contains demographic information along with established scale scores of 515 both allotment and non-allotment owners to explore their time in nature and the impacts of this on mental health. Questions were also asked around time and activities in nature. The age range was between 18-85 years old. The data had approval from the research ethics committee. Before data collection began, full informed consent was obtained from participants as well as information sheets provided to them and all participants were debriefed afterwards. Identifying information was removed to ensure confidentiality and anonymity. The scores for scales used are included.

In psychological science, replicability-repeating a study with a new sample achieving consistent results (Parsons et al., 2022)-is critical for affirming the validity of scientific findings. Despite its importance, replication efforts are few and far between in psychological science with many attempts failing to corroborate past findings. This scarcity, compounded by the difficulty in accessing replication data, jeopardizes the efficient allocation of research resources and impedes scientific advancement. Addressing this crucial gap, we present the Replication Database (https://forrt-replications.shinyapps.io/fred_explorer), a novel platform hosting 1,239 original findings paired with replication findings. The infrastructure of this database allows researchers to submit, access, and engage with replication findings. The database makes replications visible, easily findable via a graphical user interface, and tracks replication rates across various factors, such as publication year or journal. This will facilitate future efforts to evaluate the robustness of psychological research.
