Touch Screen

The issue I am having with my task is that on the screen there are two designated areas (two pictures side by side) where participants should touch either picture and it records their response. However, if they accidentally hit any area outside of these two pictures, their response is blank. Is there something I could check off so it would only respond to the designated areas where the pictures are and nothing would happen if they touched outside of these areas.

If anyone knows how to resolve this I would really appreciate it!

Thank you,
Shanna

SuperLab provides an option to do that. When in the Participant Input dialog, click on the Options tab and turn on the checkbox Ignore a mouse click unless it falls inside an area defined as a response.
