The dataset from on Von Bastian et al. (2015) on the Stroop task.

stroop

A data.frame of 11245 rows and 7 columns

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
rtS: Numeric values giving the response time in seconds

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.
