What changed? How? Why?

I need help understanding what happened to my brain?

A few years back I worked in a clinic that provided ABA services to children with autism. I was a babysitter prior and never worked with the autistic community.

Because I didn’t know anything about ABA, my boss assigned me a BCBA /Mentor to trained me so I could provide the services needed to help the clients. In Addition I was told to do the RBT course online to get certified. My mentor/BCBA taught me all about prompts, data collection, intervention etcetera. After like 6 months to a year I started to feel different, like I could study better and actually learn things more easily (it’s been hard for me to study anything consistently without losing focus, finishing anything and felt like there’s no retention of information) I could also feel more confident and even teach better to the clients. It felt like the BCBA unlocked something in my brain but can’t really explain what exactly it was.

Any BCBAS out there would you be so kind to share/explain why this happened?

Thank you
