Document Summary
Subliminal: stimulus so weak or brief that, although received by senses, cannot be perceived consciously. Results: no increased calls, when informed and asked to guess, 500 people responded. Half claimed to be made hungry or thirsty. Despite research: persistent belief in subliminal persuasion, examples: If you play music (or speech) backwards, you may hear discernible words/phrases: some famous examples: Another one bites the dust queen. Backward messages are subliminally perceived when listening forward. Because subliminal, messages cannot be consciously resisted. Evidence: teens who listen to rock and roll more likely to do behaviours. Could be third issue (wanting to be cool: criticisms: People can detect meaningful patterns in anything, especially when told what to listen/look for. Top-down processing: when our perceptions are influenced by our expectations or knowledge, as opposed to bottom-up processing, in which our perceptions are determined by the available sensory information. No evidence that backward messages can be perceived.
