Experimental: Implementation intention

It may be helpful for you to plan when and where you will brush your teeth each day over the next month. Please write below when, where, and after what activity you will brush your teeth (e.g., at 8.00 a.m. and 9.00 p.m. in the bathroom after eating breakfast/dinner). Because you should brush your teeth twice a day, please make two plans.
