I am trying to write directrt code for a version of the face-in-the-crowd task. To do this I need to present 9 different pictures (arranged in a 3x3 grid) simultaneously. The participant is supposed to click on the correct picture (while recording click response time) and noting which picture was clicked. If the correct picture is clicked a green check is displayed but if the incorrect picture is clicked a red x is displayed.

This doesn't seem like that hard of a thing to do (just need to record RT of click, and which picture is clicked on) but I haven't been able to find anything that explains how to do this. Any help would be greatly appreciated!

Thank you!
