However, by adding this instruction, you may also dilute the response time differences that your are trying to find (whether between or within subjects). If you are lucky, you are just adding random noise, however it is more likely that you will add confounds or tap into different ...

Something else to try, is to pick a highly cited paper that you did find, and then search ...
