# Description We refer users to the article for all the details about the experimental design, experimental stimuli and software used to collect responses. File is in a comma separated values (CSV) format, with the first row being a header row with names of the variables. There are no missing values in the whole dataset. The data was minimally processed - only variables that could potentially be used to identify the participants was removed. The dataset contains 60 variables with 15600 observations in total. These are results of 78 individuals, 200 obervations per individual. The variables in the dataset are described in more details in the code sheet section below. ## Code sheet Description consists of three elements each separated by a hyphen, first being the exact name of the variable used in the dataset header, second element is a brief description of the variable while the third element is type of the variable. 1. **subjectID** -
