A young Selena Gomez, after appearing on Barney with Demi Lovato she then appeared in ‘Brain Zapped’ (you can’t make this stuff up!), which is undoubtedly a reference to her electroshock dissociation programming (note in the poster the electroshock symbol is pointed at Selena’s head [purple 'Brain' and green 'zapped'), confirmed by her singing the song for it (she's about age 12-13 at this point) loaded with MK themes ('mind spinning', reading books taking you to "another world" [you dissociate into what your mind is exposed to; i.e. what Monarch slaves are allowed to read is organized for programming so their dissociation is controlled], “don’t really know where I’ll be going next cuz I’ve been brain zapped”, it’s pretty much all MK).
A basic component of the Monarch program is lots of electro shock. Stun guns, staffs with hidden electric cattle prods, and cattle prods are frequently used on the slaves. Electroshock is used to create the dissociation from trauma during the programming, and later it is used to remove memories after the slave has carried out a mission, or to instill fear and obedience in a reluctant slave.
