Add a loop around your trial routine and give the path to your conditions file in the Conditions field. Once we have our conditions file set up and saved in the same location as our experiment we need to give this info to our experiment. But this info will be saved to our data file, so in general it is good to be kind to future us, and think about what data you might want later when it comes to analysis. ![]() We aren’t going to use the column with the header “conditions” in our experiment. We have also added a column to code the correct answer, in this case we want participants to press the left key if the word says red, and press the right key if the word says blue. ![]() Here we have made 2 basic “congruent” and 2 “incongruent” trials. In a Stroop task the written word can either represent the same color, or a different color to the ink it is written in. The next thing to do is to think about what information changes trial-by-trial. In the Stroop task, this is simple - a word, and a keyboard response (and maybe a fixation cross to start of the trial!). OK step 1 of any experiment is to consider “what makes the main stimuli in my trial”. The Stroop task is a great starting point for learning to use PsychoPy, it is why we use it in the textbook! So let’s talk through the basics of making a Stroop in PsychoPy. ![]() How to make a Stroop task in PsychoPy ¶ A great starter exeriment ¶
