- ID
Factor giving the participant ID: 1-121
- congruency
Factor giving one of the two conditions: congruent and incongruent
- rtMS
Numeric values of the response times in milliseconds
- accuracy
Numeric values giving the accuracy of the response, here only 1 = correct
- cond
Factor giving the condition: 1 = congruent, 2 = incongruent
- trial
Numeric values indicating the trial number of the participant

Details
In a Stroop task, average response times are compared across conditions. Participants get exposed to word stimuli and are instructed to indicate the font colour of the word. The word itself is also a colour word and is either congruent with the font colour or incongruent. For example, the stimulus word “red” in blue font would constitute the incongruent condition, whereas the word “red” in red font would constitute the congruent condition.
