Auditory stimuli can also be primed subliminally through backward messages that are presented on rock music albums (e.g., the rock group Judas Priest allegedly urged teens to commit suicide by embedding the backward message “Do it”), messages that are presented on audiotapes too quietly to be heard consciously (e.g., subliminal self-help audiotapes), or hypnotic suggestion. However, priming influences behavior under limited conditions (Strahan et al., 2002). Brock and Grant (1963) used hypnosis to make participants feel either not thirsty (experimental condition) or tired (control condition) and then gave them a sauce that made them either very thirsty or slightly thirsty. The results showed that participants drank more water when the sauce made them slightly thirsty (vs. very thirsty) in the experimental condition, whereas the opposite pattern was found in the control condition. Hence, subliminal primes presented through hypnotic suggestion can influence behaviors as well as thoughts.
