What term describes the individual who provides both antecedents and consequences for the speaker?

In the context of behavior analysis and communication, the term that describes an individual who provides both antecedents and consequences for the speaker is indeed "listener." This is because the listener plays a crucial role in shaping the speaker's communication by responding to their verbal behaviors and providing feedback.

The antecedents can include prompts or cues that encourage the speaker to express themselves, while the consequences are the responses that reinforce the speaker’s behavior. This interaction helps the speaker learn the effectiveness of their communication and can lead to improved language and social interaction skills. By responding appropriately to the speaker's communication attempts, the listener enhances the learning process and promotes further verbal engagement.

The other options point to roles that may also involve communication but do not specifically capture the dual function of providing both antecedents and consequences in the same way that a listener does.
