I'm planning on running an experiement to test the effects of Modafinil on myself. My plan is to use a three armed study:
Each day I will randomly take one of the three options and perform some test. I was thinking of dual-n-back, but do people have any other suggestions?
Keep in mind that modafinil has a half-life of ~16 hours. You might want to allow a day in between samples. If you don't, plan to take this into account in the analysis.
Whatever test you do, try it a bunch before starting the experiment to get through a lot of the learning period.
Thanks for the suggestions!
My plan was to include a 1-day lag of the independent variable as a control variable in some of the regressions and see what effect that had.
Yep, plan to do that, and then also add a 'date' control variable as well.
