• Evie Vergauwe, PI • Miriam Fergnani, student • Rim Nashwan, student • Caro Hautekiet, Ph.D. student We are all affiliated with the University of Geneva and are collaborating with the Accelerated CREP to replicate the Turri, Buckwalter, & Blouw (2015) project. We are completing a direct replication as part of a research internship in the working memory, cognition and development lab. We are completing the study in the lab recruiting from our undergraduate students in the introductory to psychology of cognitive development participant pool (we aim for a sample size of 40 participants). We will use the link provided by the Accelerated CREP team. We have collaborated with the lab of Florian Cova to create the French version of the study. Findings We tested a total sample of 45 participants. After exclusion of one participant who did not have the majority age of Switzerland (i.e., 18 years old) or older, one participant who answered incorrectly on all comprehension questions, and one participant who self-reported that his/her understanding of the testing language was "not well" or "not well at all", we were left with 42 participants. The results seem to be in line with what is found in the original paper by Turri et al. (2015; Experiment 1). When we look at the Bayesian ANOVA for Knowledge attribution with condition (three levels: gettier, ignorance, and knowledge) as a within-subjects variable, we can see that the model including condition fits the data 9.31 times better than the null model. When we compare the conditions more specifically in the Bayesian t-tests, we can see that there is moderate evidence against a difference between the gettier and knowledge conditions (BF01 = 3.86) and some weak evidence in favor of a difference between the gettier and ignorance conditions (BF10 = 1.78). The Bayesian ANOVA for Reasonableness with condition (three levels: gettier, ignorance, and knowledge) as a within-subjects variable, shows that the model including ‘Condition’ fits the data merely 1.05 times better than the null model, only including ‘Participant’. There seems to be no evidence for a difference in reasonableness allocation between the different conditions. These results align rather well with what we can see descriptively in the plots and what was found in the original paper by Turri et al. (2015; Experiment 1). Thus, it seems that there is some difference in knowledge attribution between the different conditions, while reasonableness remains more or less the same across conditions.
