In a stroop-like task, I would like to set some “condition expression” options in order not to have repetition of color or word dimension from a trial to another.
I created some variables (I have four words and four colors) and set condition expression for each trial :
For instance, when a trial color is BLUE, I set the following condition expression in the when to present frame :
“Current trial’s code value is not set up to color (variable) BLUE”. Si that I hope to obtain a different color in each trial.
The problem is that, when I set this up for all of the events, it does not seem to work : when I start the experiment, nothing happens and it seems that there isn’t any trial that suits condition expression and that can be “presented”.
Anyway, there may be a better way to control a trial-to-trial (no-)repetition.
I hope you understood the issue since I’m not a native english
