Fixed Per Block Feedback
I'm creating an experiment with fixed feedback, where 80% of the time it gives positive feedback (or negative, dependent of the condition) and 20% of the time the participant receives neutral feedback. Feedback is to be given every 10 trials, with a total of 100 trials. I've found out how to give feedback per block as opposed to per trial using the 'Cats, dogs and capybaras' tutorial and I've followed another post on here about how to give feedback with different proportions (http://forum.cogsci.nl/index.php?p=/discussion/328/open-how-to-create-feedback-with-different-proportions) but this results in two separate versions and I'm not sure how (if at all) to combine the two.
Any suggestions would be greatly appreciated!
