"Mоmmy, mоmmy, mоmmy," your young son аsks frаnticаlly. "Can we please buy a new PlayStation®4 console with all of the games and the wireless controllers so that we don't have to sit near the television?" "No," you reply, "we can't afford to buy all of that!" Seemingly unperturbed by your rejection, your son comes back with "Then can we just buy one new game for our PlayStation®3?" "Okay, I guess so," you answer, not realizing that your precocious son has taken a social psychology class and has just used the __________ technique to get what he wants.
