-Stroop - measuring reaction times to incongruent stimuli
-============================================================
-
-The experiment
-------------------------
-
-In this task subjects must report the color of the letters spelling each
-word, but letters themselves also spell a color name and this may be the
-same or different to the color of the letters. Stroop (1935) reports that
-reaction times are slower the letters spell a color that is incongruent
-with the color of the letters, indicating a compulsory automated reading of
-the word.
-
-Analyzing your data
-------------------------
-
-After you run the study, look in the data/ folder next to where the
-experiment was saved. There will be an xlsx file there that can be opened
-with Microsoft Excel or similar spreadsheet package. Each row represents
-one condition (trial type) and each column is one variable of your experiment
-or type of data collected.
-Take the average of the resp.mean_rt column for the 3 congruent conditions
-and compare them with the 3 incongruent conditions. In most cases the
-incongruent conditions will have larger reactions times.
-
-Notes
-------------------------
-
-This version of the Stroop effect is a very simple experiment, good for
-explaining how the PsychoPy Builder interface works with minimal clutter.
-You could (as a challenge) add practice trials and feedback if you liked...
-or you could go to the StroopExtended version that's built in to PsychoPy's
-demos menu and see how to do it there!
