OS Win 11 PsychoPy version 2021.2.3: Standard Standalone? (y/n) Y What are you trying to achieve?: I have an experiment which basically just several questionnaires one after the other. Each questionnaire is a series of questions. I desgined the expermient so that each questionnaire is a separate routine, and the questions themselves are each a single item in the conditions file of that routine. So for example, questionnaire #1 has a 50 item condition file that loops once, sequentially, through the items. The user answers the questions using a sliding scale presented at the bottom of the screen.
I now want to add a button that will allow the user to move back to the previous question in case they want to change their reply. So basically, to go up one row in the condition file.
Well that is helpful and easy to understand for a non coder like me, but if I’d like to also record the users response to each slide
so for example, on top of the image files of each slide I’ll also have a slider component, and everytime the user clicks on the slider I want to move one slide forward and record the response, and every time they hit “back” (or left arrow as in your example) I want to go to the revious slide and enable hte person to change their reply
