Interaction: focus on reward, happy thoughts, factorial design, factor #1, visibility (2 levels, more than 1 independent variable, ie. Marshmallow exposed vs covered: factor #2, thoughts (3 levels, tell different groups to think of different things, ie. Influenced by the researcher: cell phone use and driving, ie. Increase if study carries over a long period: testing, changes behaviour, similar to being observed. Get less stressed on their own: regression to the mean, start out at an extreme end of something on their own and it goes up/down. Someone starts off really stressed and can only go down. Start extremely calm and can only go up: one group, post-test only. Assume dv shows a low rate of smoking following competition of program: does the training program work, weakest design, nothing to compare it to, appropriate for certain situations, one group, pre-test post-test, single or multiple pre-tests and post-tests.
