Help with lexical decision task
I'm trying to set up a lexical decision task but after some research I still don't get some points (I'm new to OpenSesame and programming).
I have a list of 192 letter strings (in a txt file), of which 96 are words and 96 are nonwords. I want to present them in blocks of 24 trials where half are words and half are nonwords, but obviously randomized. I don't want the same string to be seen twice and I would like to change the order of presentation for each participant. Can I do it with the user interface or do I have to use Python? And if I have to code, is there a tutorial for something like this?
Thank you so much in advance!
