Here you can configure application settings:
You will see images (choices) in front of you. These images will be somewhat similar but also different from each other.
If you think one of the images is different from the others click on this image (choice).
If you think that none of the images are different from the others, do not click on any of the images, just click on the button for the next task (bottom right).
To return to the previous task, click on the button at the bottom of the screen ("left arrow"). You can then cancel your choice by clicking the same or another image again.
The correct choice has a different background color than the other images (if it exists).
Do not work too fast as some stimuli will change over time within the same task.
Your results will be displayed at the end of the task.
