Help us out: Survey about Hyperfixations

Hey there fellow hyper fixators! For school my friend and I are required to do a study about differences between Hyperfixations in people with Autism and people with ADHD. For this I would love if some of you could talk about your experiences of Hyperfixations, using the questions below or however you want. The questions are more for guidance:

Can you explain in your own terms what a Hyperfixation is and what Hyperfixation means to you?

What is/are your Hyperfixation(s) at the moment?

How long have you had these Hyperfixation(s)?

Why do you have this Hyperfixation? What do you like about it?

From what age did you notice that your Hyperfixations had a pattern? And from what age did you notice a pattern in them?

How often do you think about your Hyperfixations?

Have you ever gotten into a Hyperfixation thanks to someone else's influence?

Or have you gotten an new Hyperfixation by some form of social media?

Do you know people with the same kind of Hyperfixations as you?

Do you yourself create things related to your Hyperfixations?

Thank you in advance! (Pardon my spelling, I am natively Dutch.)
