““Graffiti and Tearing55: Designed by Norlander et al. (1998) participants are given an illustration of "Adam and Eve in the Garden of Paradise" and are told to draw or doodle on it (hence the "graffiti” part.) Next, they are given an illustration of "Samson and the Lion" which, theoretically, is intended to provoke participants to exhibit aggressiveness. The participants are told to tear apart that image into little pieces. The number of graffitis and their content (if sexual or violent) and the bits and pieces from the second image are the dependent variable (i.e. the thing being measured,) and, allegedly, an indicator of aggression. The experiment can be adapted to study the influence of sex differences, alcohol consumed before the experiment, or any variable you can imagine (like having played video games before the experiment.)””
