Résumé

The thesis revolves around the topic of the acquisition and rewiring of probabilistic information. The main objectives of the thesis are (i) to determine how statistical learning relates to prefrontal cortex-dependent cognitive functions, (ii) to determine how the rewiring of probabilistic knowledge relates to prefrontal cortex-dependent cognitive functions, and (iii) to determine the neurophysiological correlates of the rewiring of probabilistic knowledge. Four main studies are planned in relation to these objectives. The first study focuses on the relationship between statistical learning and executive functions. The second study will explore the effect of statistical learning on working memory. The third study will explore the relationship between rewiring and executive function. The fourth study will examine the neurophysiological correlates of rewiring using EEG. Advancement: Data acquisition for studies 1, 3 and 4 is completed. Data acquisition for study 2 is in process. Study 1 is finished; the manuscript is under review at npj Science of Learning. Preliminary results for studies 2 and 3 have been done and are expected to be finished on May 2024 and November 2023 respectively. The EEG data of study 4 has already been preprocessed. The formation needed for the analyzing the data of study 4 has been completed. Data analysis for study 4 is expected to be finished on April 2024. The candidate is already familiarized with the literature and theoretical background of the project. The next steps of the thesis will be to finalize studies 2, 3, and 4 and write the corresponding articles.
