I am new to programming and have a problem. I need to create a procedure where 4 different visual stimuli will appear in 4 lolalizations on the screen (upper right corner, lower right corner, lower left corner, upper left corner).
Each stimulus must appear in a given location twice (i.e. 32 repetitions). Can somebody tell me how can I do that? I was thinking about creating a text file with the names of the stimuli (which I have in the folder) and the names of the positions in which the stimuli are to be placed (for the program to choose from this list). I just don’t know how to define positions … and let the program choose from this list.
