Description acceptable. At the University of Akron, this object is exhibited at the end of a hallway where many visitors will step on only black floor tiles. A book by Gina Perry about the disorganized use of this object describes that 75% of people were not “de-hoaxed” right away. Arnold Buss adapted the design of this object to measure human aggression with a 1-10 scale. Laters users of this object were told over a (-5[1])(*) PA that a man had a heart (10[1])condition. People chosen to use this (10[1])object were subject to verbal prods like “It is absolutely essential that you continue.” Volunteers designated as “teachers” would use this object after a “learner” failed to correctly identify a word pairing, causing the learner to produce a fake scream. For 10 points, name this machine used in an experiment at Yale by Stanley Milgram that supposedly administered a painful punishment. (10[1])■END■
