Please try again later. Reference #15.bdc58f18.1422230919.3c4ce46 ——————————————— Right now my study has 3 different blocks of distinct reaction time measures in it. Is it possible for me to have too many trials, which messes up cache somehow? April 1, 2015 at 7:34 pm #1997 Henk van SteenbergenKeymaster Dear Ezra, I guess too many trials should not be an issue. Perhaps there was a temporary problem with the Qualtrics server? Did you find the solution in the end? Best, Henk Author Posts Viewing 2 posts - 1 through 2 (of 2 total) The forum ‘Support’ is closed to new topics and replies.
