Can you override priming? Assume that you are using priming as a technique to improve your performance in a specific area. Ex: When I am sleepy in the morning I use more alert music to get my mind up to speed. If I want to stay focused I try to visualize a focused person or I try to focus on an object for a few minutes. With these I am trying to used the ideomotor link (as Khaneman calls it) and to increase the concentration power directly or indirectly.

Now let's assume that I want to go back and get out of being focused and staying alert and I expose myself to stimuli that would send me in the opposite direction. Would the initial priming be an obstacle in this direction?

Note: in Kahneman's example imagining yourself smiling will actually improve your mood. Same way, imagining yourself concentrating on something should improve your focus.
Would the initial priming be an obstacle in this direction?


Yes. But not an exceedingly difficult one to overcome since you manage to prime yourself into being focused in the first place. 

Personality plays a vital role of course. If you're a natural hyperactive person it would obviously be an easier task to prime yourself into being alert than to enter a state of complete focus and calmness.
