What does EBI mean in ABA?

Excuse me, but could you clarify for me what the acronym "EBI" stands for in the context of ABA? I'm not familiar with this particular terminology and would appreciate it if you could provide a brief explanation. It's possible that it refers to a specific concept, strategy, or tool within the ABA framework, but without more context, it's difficult for me to give an accurate interpretation. Thank you for your assistance.
