I recently was checking my data folders to ensure that the data was being recorded accurately and it looked fine. I wanted to run through again as a fake participant just to make sure, made a spelling change within a questionnaire, then ran through the experiment and the word "ok" appeared in the data file and threw off the data by one. I have never had this happen before, just by changing the wording in a questionnaire it has never effected by data file, could something else be the cause? And how might I remedy this?
