Display multiple images and record which image is clicked w/ RT
Display multiple images and record which image is clicked w/ RT
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!
Hm - this experiment should definitely be possible. First off, you may want to run through the lightgun experiment within the samples folder (group 6). You may also want to read up on the information found here:

If the right image is selected, you could then overlap the images or clear the screen and present either the check or the 'X' . If you would like, I can provide further assistance on getting this project started for you. Please let me know if you have any additional questions or if I can help in any way.
For help on displaying the images in this manner (a 3x3 grid), see the following link:
