I believe that marik is correct. Once we've been trained in the fundamentals and fine points, for awhile thereafter we might examine the figuration in a score and make mental notes like, "I should play these octaves with forearm staccato", or "I must voice the tops of these chords by weighting the fifth finger in a certain way", or "to avoid a clash of hands, the left wrist must be raised and the right wrist lowered in this spot", or "I need to lower my shoulders to reduce tension", etc. etc.
But over time, these things come more naturally, and conscious thought about them becomes more infrequent. As we gain mastery, the music determines the motions. The pedagogue Josef Gat (ignore the anatomical mumbo jumbo in his book and focus only on the the practical and applicable ideas) referred to "synthesizing" and "adapting" motions. Unlike demonstrating a flexible wrist, a curved hand position, or how to produce a rich tone, these so-called "synthesizing" and "adapting" motions are difficult to impossible to teach--they are more complex involving approaches that go beyond fundamental teachings, but nonetheless, also obtain the desired results. The pianist develops these motions naturally and in the moment, often as effective coping motions and without any conscious thought. It is really the music that necessitates these synthesizing and adapting motions, as well as differing tempos.
Yes, once in a while, if a passage seems intractable during practicing, one might have to pause, observe the motions several times, analyze the problem, and find a solution that might involve better choreography of the hands, for example. But most often, the music will generate the appropriate responses in terms of effective movements and motions in the playing.
