For my study, I am testing whether people have a preference for the Republican or the Democratic party. I am running political honestly scores across the screen, for both parties. My plan is to have the first score that appears on the screen to either be a good Democratic or Republican scores and then all the scores afterward will be randomized. So every score that will appear on the screen first will either be a good Republican or good Democratic score. 

For my current script, I have figured out how to randomize scores using lists, but is there a way where I can pick whether a good Republican/Democratic score will run first and then have the rest of the scores run at random?

Any advice would be greatly appreciated!

Create two <text> elements -- DemPlusfirst and RepPlusFirst --, put them in a <list>, sample the first stimulus from that <list>.

Sample the remaining stimuli randomly from another <list>.

Create two <text> elements -- DemPlusfirst and RepPlusFirst --, put them in a <list>, sample the first stimulus from that <list>.

Sample the remaining stimuli randomly from another <list>.


I followed your advice and it worked. Thank you!
