(2012) deems vocal talk important to the incubation process. Their study concluded that individuals who receive an inoculation message that contains threat will talk to others about the message and talk more frequently than individuals who do not receive an inoculation message. Additionally, the act of postinoculation talk bolsters their attitudes and increases resistance to the message as
