From the people who are not familiar with studies conducted in the software usability labs, quite a common question is - Aren't test participant aware of the very visible camera pointed at them and the monitor and therefore they would not be at their natural self?

I guess same thing is true in our daily life, once we are focused on task at hand (grocery shopping, catching bus, or driving safe...) we would stop being aware of things which doesn't come in the way of that task.
