+Stroop - measuring reaction times to incongruent stimuli
+------------------------------------------------------------------
+
+The experiment: 
+    
+    In this task subjects must report the colour of the letters spelling each
+    word, but letters themselves also spell a colour name and this may be the
+    same or different to the colour of the letters. Stroop (1935) reports that
+    reaction times are slower the letters spell a colour that is incongruent
+    with the colour of the letters, indicating a compulsory automated reading of
+    the word.
+
+Analysing 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 demo and see how to do it there!
