Hi Allan Paivio, proponent of dual-coding theory, summarized some of the potential benefits of mental practice (imagery) and (I think) some findings up to 1985. See reference below. There are numerous studies of this question, so you should be able to find more recent examples of actual research and review articles with a literature search. If memory serves correct, the effectiveness of imagery for actual skill development depends on such factors as the nature of the activity (e.g., substantial cognitive demands or not), level of training of practitioner (complete novice or some experience), and the like.

For example, if baseball players visualize themselves hitting the ball, or public speakers visualize their speech going really well - that type of thing.
