Does anyone know a study on effects of advertising on appetite in adults that didn't use complicated methods like eye tracking and methodologies that require you to be a qualified psychologist? Most of the studies on appetite is done on children and that will require a long list of ethical approval.
I'm just a second year undergraduate and I need to do the experiment and write up the report in just one semester. I don't have enough time to get trained to use eye tracking stuff and not qualified to asked participants to fast or give them food.
