Contributors to this study are Isabelle Kunz, Yannik Himstedt, Manuel Kaiser, Paul Rux, Antonia Kohler. We are all Bachelor Psychology students in our 3rd semester at the University of Kassel. Sophia Weissgerber is the supervisor of this project, which is part of the class "Lab Course Empirical Research". Our direct replication study is replicated as part of the Collaborative Replications and Education Project (CREP), which invites students to conduct high-quality replications of high impact research papers as a part of their methodological training. For more information on CREP please see https://osf.io/wfc6u/” Description of our replication methods Population For our replication of this study, the population which we wish to sample are people at the the University of Kassel, mainly psychology students. However, we will also recruit students of other subjects on the campus. Ideally, the target sample would consist of 150 participants according to power analysis. Procedure We plan on conducting a direct replication keeping materials and procedures as similar as possible. As in the original study, we will be investigating mind wandering and its effects on performance. To do this, we will be using the original difficult and easy text passages and test questions translated to German. The eight orignal passages the authors used were from the Nelson-Denny Reading Comprehension test, version E. The replication takes place in Germany, therefore we translated the eight easy and eight difficult passages into German via a translate and backtranslate procedure. We use the same test questions as in the original, just translated to German. Our programming is also done in opensesame in accordance to the orginal. To conduct our study, participants will be brought to a room with several computers. To standardize the conduction of our study, we have created a script that will be read at the beginning of each session. Our participants will be given instructions both verbally and via the computer regarding the passages that will follow on the computers in front of them. Participants will read eight passages that will alternate between easy and difficult texts, like in the original. After important text passages (which content will be later tested with the test questions), the participants will be interrupted and asked whether or not they had been mind wandering while reading the passages. The mind wandering prompts are inserted in the same spots as in the original. Following the passages, participants will be subject to comprehension questions to analyze their comprehension and understanding of the material (also like in the original). After the completion of the study, students will be asked if they have more questions, debriefed and rewarded with a chocolate bar. Analyses In order to accurately analyze the data we will be collecting, we will be utilizing the same tests ran in the original study. We will be conducting both mixed-effects linear regression as well as mixed-effects logistic regression models to analyze reading times, the frequency of mind wandering, and overall reading comprehension. The analyses will be run on R Studio with the code given by the original authors.
