Great question and a concern for everyone. With all of the bookmarks I have collected over the years, I find myself at a loss to find "solid" evidence to answer your question.
From personal experience, I use the technique of after reading the question, if there are any words/terms I am not comfortable with, re-read the passage either without those words or with a substituted word that I do know. I even use this method when doing math problems. I ignore the numbers and concentrate on that I need to do. Then I go back and use the numbers.
Is there an official term for this removal or substitution of information? What methods do you currently use?
