mmediacy does not imply softness or easiness. It is just as important to establish your credibility on the first day as it is to establish interpersonal trust and a climate of closeness, and in fact, immediacy and credibility are relational. Studies have shown that students perceive teachers with positive immediacy behaviors to be more credible (McCroskey & Wheeless, 1976; Thweatt & McCrosky, 1998). Being prepared and organized also add to your credibility as well as your appearance. Remember, the first day is your best opportunity to set a high credibility threshold. It’s much harder to lower a credibility threshold that has been set high on the first day and even more difficult to raise the threshold if you did not raise it on the first day.
