COGLAB ASSIGNMENT #1: STROOP TASK
Instructions:
Read through the introduction to the Stroop task (online, and on pages 24-26 of the CogLab Manual).
Go to the CogLab Homepage (www.coglab.wadsworth.com), select Stroop Task (under Attention, upper
left), log in, read the instructions, and do the experiment. Be sure to rehearse the mapping of the colors
to the response keys a bit before you begin. Try to ignore the word, and concentrate on the color. Be
sure to respond as quickly as you can once you’ve made your decision, but remember that incorrect
trials will be repeated, so try to keep error rate low.
[NOTE: When I first tried out this year’s version, the display did not respond properly to my key
presses, and there were overlapping stimuli. If you have any problems like this, try closing the
experiment (by clicking the X in the upper right corner), then clicking Return to Experiment.]
Once you finish the experiment, you should return to the Coglab page where the class’s average results
appear at the bottom of the page. Click the link to get your own results. Copy the results below; say
YES to have your results included in the Global Averages.
Your Results:
Name and Font same:
______ msec
Name and Font different:
______ msec
Questions:
(1) Did you obtain a “Stroop Effect?” How does your data show that?
(2) How do you think color naming time for a color-block, as we did in class, would compare to the time
for the condition where the Name and Font were the same? Why is that?
