 So John Vokey and Don Reed wanted to find out exactly what people could do with backwards messages So they did an experiment. They recorded a bunch of voices from different genders, so male and female They recorded a bunch of voices of people from different countries, so different languages, so French, German and English They recorded people asking questions, and they also recorded people just saying declarations and The question was what can people do with these messages when they're played backwards So what exactly does a backwards message sound like and what can people pick up? So they found there are a couple of things that people could do with backwards messages and a couple of things that they couldn't do The things that they could do with backwards messages was tell the difference between gender whether it was a male or a female speaker talking They could also tell the difference between Different languages so whether somebody was speaking German or English and they could also so when there was two males speaking Backwards they could tell the difference between Speaker A and speaker B There was also a couple of things that they couldn't do well So you might be able to think you may think that participants would tell the difference between a question and a declaration because a question sort of Ends with an inflection, but they couldn't do that They also couldn't tell the difference between a sentence that was with words in the correct order and a sentence where that was completely scrambled But the most important thing they were trying to tap into this experiment was sort of unconscious Processing is there anything that people are able to pick up? Without their awareness. So they asked people to categorize these backwards sentences as either Christian or satanic or even pornographic and they found that people could not correctly Classify these things so one of the sentences played forwards was Jesus loves me this I know and people Couldn't correctly classify it as pornographic or Christian So what happened with the Judas Priest trial? Well, I told you it was an awesome story and now you've seen how John Vokie looks you should see how it played out in court
