To essay this , the study oppose a grouping of nonsmokers against a nonexistent game opposite whose " behaviour " was designed to irritate and provoke . The simple computer game imply a race to see who could click a shiner button fastest in response to interpret a crimson square seem .
The kink – participant in the plot could set punishments where the loser would have to hear a blast of white noise over headphones . Winners could set the intensiveness and length of the annoying sound , but players could also see what the other person had adjust as a punishment level .
investigator who control the phony opposition gradually raise the punishment level for the field of study participants .
