We need Ss to type an autobiographical narrative after a cue. We dont seem to be able to find any instructions about accepting string entry, displaying to the Ss their strings in a text box, or any aspect of storing or saving strings as responses.
Once in Participant Input, select Keyboard-String Input, there are two tabs you should take a look at. The Display tab and the Response Completion tab. Here you will see options on how to display the text box and how you want to participant to continue once they are finished. The participants responses will be saved to the data file by selecting Save collected data, which comes up after you press the run experiment icon.
