The problem is amplified by the difficulties associated with recruiting infant participants for research as well as the increased variability in infant responses. With sequential testing designs providing a viable alternative to paradigms facing such issues, the current study implemented a Sequential Bayes Factor (SBF) design on three findings in the developmental literature. In particular, using the framework described by Schönbrödt and colleagues (2017), we examined infants’ sensitivity to mispronunciations of familiar words, their learning of novel word‐object associations from cross‐situational learning paradigms, and their assumption of mutual exclusivity in assigning novel labels to novel objects. We tested an initial sample of 20 participants in each study, incrementally increasing sample size by one and computing a Bayes Factor with each additional participant. In one study, we were able to obtain moderate evidence for the alternate hypotheses despite testing less than half the number of participants as in the original study. We did not replicate the findings of the cross‐situational learning study. Indeed, the data were five times more likely under the null hypothesis, allowing us to conclude that infants did not recognize the trained word‐object associations presented in the task. We discuss these findings in light of the advantages and disadvantages of using a SBF design in developmental research while also providing researchers with an account of how we implemented this design across multiple studies."],["dc.description.abstract","Results of the sequential Bayesian analysis of the mispronunciation effect. image"],["dc.description.sponsorship","Leibniz ScienceCampus Primate Cognition"],["dc.identifier.doi","10.1111/desc.13097"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/82567"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-399"],["dc.relation.eissn","1467-7687"],["dc.relation.issn","1363-755X"],["dc.rights","This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited."],["dc.title","Sequential Bayes Factor designs in developmental research: Studies on early word learning"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

Fifty German-English bilinguals learned unfamiliar German and English negative and neutral words in 2 different learning conditions: One group (emotion video context) watched videos of a person providing definitions of the words with facial and gestural cues, whereas another group (neutral video context) received the same definitions without gestural and emotional cues. Subsequently, participants carried out an emotional Stroop task, a sentence completion task, and a recall task on the words they had just learned. We found that the effect of learning context on the influence of emotional valence on responding was modulated by a) language status, L1 versus L2, and b) task requirement. We suggest that a more nuanced approach is required to capture the differences in emotion effects in the speed versus accuracy of access to words across different learning contexts and different languages, in particular with regard to our finding that bilinguals respond to L2 words in a similar manner as L1 words provided that the learning context is naturalistic and incorporates emotional and prosodic cues."],["dc.identifier.doi","10.1037/emo0000263"],["dc.identifier.gro","3151002"],["dc.identifier.pmid","27991815"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7811"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","1931-1516"],["dc.title","Effects of learning context on the acquisition and processing of emotional words in bilinguals."],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]
