Final Answer:
Greg's behavior, where he pays attention selectively and focuses on certain information, is an example of selective listening. Option A (Selective listening) is the answer.
Step-by-step explanation:
Selective listening occurs when an individual chooses to concentrate on specific information while disregarding or filtering out other content. In Greg's case, he selectively listens to the conversation about celebrating the end of the project, indicating that he tunes in when the topic is of personal interest.
This behavior contrasts with pseudo listening, where someone pretends to listen, mindless listening characterized by passive reception of information, prejudgment involving forming opinions prematurely, and defensive listening marked by reacting to perceived criticism. Greg's attention shift aligns with selective listening, emphasizing his choice to engage with information that is relevant or significant to him.
Option A (Selective listening) is the answer.
