Document Summary
One rock group accused of encouraging suicide by including command do it recorded backward. Begg, needham, bookbinder examined this by playing backwards or forwards message and tested whether people could recognize message played backward and whether they agreed with message played in forward direction. Found that hearing backward message helped you recognize same message played backward again but meaning was lost. Subliminal perception perception of stimulus, as indicated by a change in behaviour, at an intensity sufficient to produce a conscious sensation. Person denies detecting stimulus yet stimulus has measurable effect on behaviour. Effects are subtle and special procedures required to demonstrate them. Merickle some tapes contain messages that are too weak for human ear to detect under any conditions and some when subjected to specrtographic analysis (detects voiceprints) contained none at all. Pratkanis tapes for memory or self-esteem participants didn"t know which was which and mixed them up.
