I am attempting to write a file where I have multiple responses per trial. I've read up on this in the manual, however I have run into some trouble. Everything works fine when the two trials on the same line have the same correct and incorrect responses, however, when the two trials are suppose to have different correct responses, the program doesn't register incorrect responses. For example, a line works fine if both time columns have the rt:18,23 listed as the correct response. However in a line where the the first time has rt:18,23 for the correct response, and the second time has rt:23,18 for the correct response, for both times the program counts either both keys 23 and 18 as correct responses. Is there some way to get trials that require different keys for correct responses on the same trial line?
