Replicability is a cornerstone of scientific progress. Yet, replications are often undervalued, and are sometimes seen as redundant, unimportant, or lacking novelty. This impedes their broader adoption in research and beyond. In response, the credibility revolution calls for slower, more deliberate science and greater responsiveness to fallibility. In this perspective piece, we argue that (a) replications are essential for validating scientific claims, (b) replications need to be made more visible, recognized, and integrated into research and educational practices, and (c) we can change the way we view and judge replication results. We propose a framework where replication studies can be systematically tracked and normalized through the Replication Hub as part of the Framework for Open and Reproducible Research Training (FORRT) initiative, with the goal of enhancing the visibility, integration, and cumulative impact of replication research across disciplines.

Early learning of a second language at home has been found to be beneficial for children’s cognitive development, including their ability to ascribe mental states to others. We investigated whether second language learning in an educational setting can accelerate children’s sensitivity to a communication partner’s perspective and whether the amount of exposure to second language education makes a difference. We tested three groups of English monolingual four-five year old children with varying language exposure at the beginning of their first year at primary school and 24 weeks later. Children attending bilingual schools and children with weekly second language lessons exhibited similar accelerated development of communicative perspective-taking skills compared to children without second language provision. Such advances were not related to other cognitive advances. Thus, limited foreign language teaching might boost young children’s development in communicative perspective-taking skills, providing an enhanced basis for their social competence development.

Can exposure to a foreign language in the first year of school enhance divergent thinking skills? Ninety-nine monolingual children from predominantly White neighbourhoods (M_Age = 57.7 months, SD 1.2; 47 girls) attending bilingual schools, schools with weekly foreign language lessons, or schools without a foreign language provision (= controls) completed divergent thinking and executive function tasks at the beginning of the school year and 24 weeks later. The groups did not differ on creativity measures at the beginning of the school year. Only bilingual school children and weekly language learners improved divergent thinking at the second testing point, with the former significantly outperforming controls on creative fluency and flexibility. Improvements could not be explained by executive function development. Therefore, a considerable amount of exposure to a foreign language in early formal education appears to boost creative thinking.

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.

Children who can speak more than one language show advantages in Executive Functions(EFs) and perspective-taking (e.g. Fan et al., 2015) as compared to monolinguals. Bilinguals’superior perspective-taking abilities have been explained by enhanced inhibitory control(Goetz, 2003; Kovács, 2009). However, enhanced perspective-taking in bilinguals is arguedto be social, not the result of an inhibitory control advantage (e.g. Fan et al., 2015; Libermanet al., 2017). To address this debate, we explored the inhibitory control and the social accountby asking 40 monolingual and 42 multilingual 4-to-7-year-old children to complete twoconditions: a social (i.e. Director) and non-social (i.e. Camera) versions of a referentialperspective-taking task. In addition, we tested children in three different measures ofinhibitory control and in a test of emotion understanding with low demands on EFs, the Testof Emotion Comprehension (TEC; Pons et al., 2004). Multilingual children outperformedmonolingual children in both the Director and the Camera condition of the communicationexperiment. All children, both monolinguals and multilinguals, achieved overall higherscores in the social condition than they did in the non-social variant. Multilinguals alsodemonstrated superior inhibitory control in the inhibition tasks. No difference was recordedbetween multilinguals and monolinguals in the TEC. Although inhibitory control andemotion understanding were positively related with performances in the communicationtasks, neither inhibition nor emotion comprehension accounted for multilinguals’ superiorityin the Director or the Camera tasks. We speculated that a third factor, metalinguisticawareness, might be crucial for multilinguals’ superiority in referential perspective-taking.
