Final answer:
Option 4) Presupposition is an effective strategy for training topic initiation by creating an expectation for interaction and fostering active engagement in discussions.
Step-by-step explanation:
One strategy that has been effectively used to train topic initiation is presupposition. This approach revolves around the idea of assuming that certain things are true or will happen in a context without stating them outright, encouraging the individual to consider and initiate topics of discussion. For example, when a teacher poses an open-ended question that presupposes student participation, students are encouraged to initiate a topic of discussion to address that question.
Unlike strategies such as waiting, which relies on the recipient to take the initiative independently, or imitation, which involves copying behavior, presupposition promotes spontaneous initiation by priming the context for a conversation. Additionally, while the question and answer technique can help encourage topic initiation, presupposition goes a step further by creating the expectation for interaction, thus fostering more active engagement.
