Hey everybody, my friend is writing a diploma thesis about spatial perception and she wanted to ask you, to fill in her experiment.
It takes about 40 minutes and requires only internet connection and your attention. If she is able to collect enough data, she will be writing also a research paper about this, so your involvement would really help.
It may seem dull after a while, but it is really important to complete the whole thing.
Thank you for your time and if you fill in the e-mail address, I will send you more information about the research.
