If this template helps then use it. If not then just delete and start from scratch.

**OS** (e.g. Win10): mac os 15.1  
**PsychoPy version** (e.g. 1.84.x): v2021.2.3  
**Standard Standalone? (y/n)** If not then what?: yes  
**What are you trying to achieve?:** I am trying to make a version of a change blindness experiment where I have pairs of images that are identical except for one change in one of the images in the pair. I have defined 9 regions in the images ( I used polygons to make the regions ), and defined what region has the correct answer in a conditions file. I want them to go in a loop until the participant taps on the correct region of the images ( the region where the change in the images happens ). What I have now are two images that each show up one time, and do therefore not go in a loop. The mouse component also does not work, and makes the experiment end with an error.

**What did you try to make it work?:** I have tried many things, such as using a mouse component, coding etc. But I do not know how to use the code component as I am just starting to use psychopy, so I may have done it incorrectly.

**What specifically went wrong when you tried that?:** When I used the mouse component ( end routine on press = valid click, clickable stimuli = corAns ) this came in the runner = “File “/Users/hrafnhildur/Library/CloudStorage/OneDrive-Menntask\xfd/2 \xe1r - haust\xf6nn/Skynjunars\xe1lfr\xe6\xf0i/Lotuverkefni - Psychopy/Lotuverkefni copy\_lastrun.py”, line 415, in   
if obj.contains(mouse):  
AttributeError: ‘str’ object has no attribute ‘contains’”

So far that works, but once I test the experiment and click on one of the words, it exits. I’ve tried pretty much all the settings there are for the mouse response, without success.
