This can be defined as when a person only responds to specific instructions, words or sentences.
This mostly applies to toddlers and young children. Some children would ignore a call from an adult but would immediately respond when the adult offered them a treat
E.g selective hearing :
The boy only responds to"come and eat".
Selective hearing refers to the way people only hear a part of what someone is saying — often, it's what they want or expect to hear — and miss out on the rest.
This tends to cause conflict, riffs and miscommunication in relationships.
