Hi Jun,
You need to use the newTrial().log command to append columns to your results lines. See an illustration in the advanced tutorial
Another minor issue is that for some reason, the Item ID for each trial was incremented by a fixed number (maybe by the number of practice trials and number of instruction texts).
Column #4 reports the order of creation of the trial: if you add newTrials above another newTrial then the latter will necessarily see its ID increase. Column #9 for each trial’s “Start” and “End” rows reports a similar information, except it applies to PennController trials exclusively
So, all things considered, nothing went wrong: you can control what information you add to each line by using newTrial().log, and you can decide to use or not use the information in column 4. Alternatively, if you have an “ID” column in the CSV table that you use to generate your items, you can append it to your results lines using .log and use that in your analyses instead of column 4
