MATLAB code for Oliveira et al 2024
Task MATLAB scripts were adapted from
Colizoli, O., de Gee, J. W., Urai, A. E. & Donner, T. H. Task-evoked pupil responses reflect internal belief states. Scientific Reports 8, 13702 (2018). https://www.nature.com/articles/s41598-018-31985-3
with code publicly available at https://github.com/colizoli/pupil_belief_states
Task and acquisition parameters are described in detail in https://doi.org/10.1101/2024.05.01.589279
Analyses scripts run on MATLAB and depend on:
eeglab functions - https://sccn.ucsd.edu/eeglab/index.php
jbfill - https://www.mathworks.com/matlabcentral/fileexchange/13188-shade-area-between-two-curves
Task scripts depend on:
