The dataset from on Von Bastian et al. (2015) on the Stroop task.
stroopA data.frame of 11245 rows and 7 columns
Factor giving the participant ID: 1-121
Factor giving one of the two conditions: congruent and incongruent
Numeric values of the response times in milliseconds
Numeric values giving the accuracy of the response, here only 1 = correct
Factor giving the condition: 1 = congruent, 2 = incongruent
Numeric values indicating the trial number of the participant
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 <U+201C>red<U+201D> in blue font would constitute the incongruent condition, whereas the word <U+201C>red<U+201D> in red font would constitute the congruent condition.
