That's easy for you to say: action identification and speech fluency.
Action identification theory holds that an action can be identified by the performer in different ways, and that these various act identities differ in their appropriateness for maintaining the action effectively. Optimal action identification exists when a personally easy action is identified in relatively high-level terms (i.e., the action's effects and implications) or a personally difficult action is identified in relatively low-level terms (i.e., the action's mechanical details). To test the optimality hypothesis with respect to speech fluency, subjects were asked to deliver a speech to either an easy-to-persuade audience or a difficult-to-persuade audience and induced to think about the action in either high-level or low-level terms. As predicted, subjects made fewer speech errors and felt more satisfied with their performance when the task was personally easy and identified at high level and when the task was personally difficult and identified at low level. Optimal action identification made things easier for them to say.
