1	data(stroopdata)

A data frame with 5401 rows and 10 columns:

subject: Case identifier, in numerals
block: Percent of congruent target_type trials in a block. 1 means 80 percent congruent, 2 means 20 percent congruent
age: Age of subject, in integers
gender: Gender of subject, in integers. 1 means male, 2 means female
order: Order of blocks, in integers. 1 means subject did 80 percent congruent block first and 20 percent congruent block second. 2 means subject did 20 percent congruent block first and 80 percent congruent block second.
font_size: Font size of the stimulus, in integers
trial_num: Trial number, in integers
target_type: Type of stimulus for a given trial. 1 means congruent stimulus, 2 means incongruent stimulus
rt: Reaction time, in milliseconds
ac: Accuracy, 1 means correct, 0 means incorrect
