I am a student and new to PsychoPy. I would like to create a children version of the Stroop Task:
Two animals are simultaneously presented, a big one and a small one (e.g. elephant and butterfly). In congruent trials, the elephant image is presented largely on screen, the butterfly small. For incongruent trials, it is the other way round (elephant image small, butterfly image large). I started by creating an excel file with my conditions: it contains the following four rows:
In every row, I have two columns for the images (left image, right image) and columns for the image sizes. I inserted specific image files, e.g. “animal_images/s1.jpg” in the cells of my excel file, and the experiment runs. Now, I would like to substitute these image files with some value that refers to some list (maybe another excel file?) where all my images are contained - resulting in a randomized selection of two images in every one of the four conditions. (In total, I have 12 big and 12 small animal images)
The solutions proposed on similar topics were not fitting or I was unable to understand them.
Does someone have an idea on how I should proceed?
