URL of experiment: Illusions [PsychoPy]
Description of the problem:
Hi, I am already running my final year project and data collection. I was confident it worked well because when we tested among 4 researchers (different computer screens), it worked fine with no problems except when using safari and we have included to use google chrome in our study advertisement.
My problem is
- 2 participants encountered that our horizontal line in the 2nd type of illusion (horizontal-vertical) is too close to the computer screen and not visible.
The participants were using 14inch and 17inch size computer. I tested the experiment on my 11inch screen and it worked well.

Although it was too close but it was still visible unlike for the affected participants
- Halfway through the experiment (middle of first type of illusion), participant said the session ended.
What could be the factors for these?
