If you’re interested in learning the terminology I would start with the cooper book
https://www.amazon.com/Applied-Behavior-Analysis-John-Cooper/dp/0134752554/ref=nodl_ This along with the 5th Ed task list gives you a lot of the technical stuff. Then expand from there.
The Cooper, Heron and Howard Book. It was white when I was in school.... a number of years ago!
Not sure if I’m allowed to link to Amazon but here goes...
Applied Behavior Analysis https://www.amazon.ca/dp/0134752554/ref=cm_sw_r_cp_api_fabc_RryVFbRT62HPX
I found the 3rd edition preorder on amazon while I was looking for gift ideas for a bcba I know.
The core of ABA is in this book: https://www.amazon.com/Applied-Behavior-Analysis-John-Cooper/dp/0134752554
It's like the bible of ABA.
