Identifying iv and dv: dr. smith examines how daily exposure to a sun lamp (1 hour of exposure or no exposure) impacts peoples depression levels in the winter time. Gets the manipulation (play the video game) Equivalent but does not get the manipulation/treatment. Control group will go through same procedure but will not get the treatment (example of the violent video games - they would not get to play the video games!) When researcher preconceived ideas cause to find what they expect to find. Can influence the participant or the researcher e. g. , can be subtle- head nod, smile.
