She also discusses the interaction between audio and visual cues.

Ultimately it comes down to both the physical capabilities/limitations of our senses to recognize stimuli and how the mind contextualizes that stimuli using our existing mental models.

Ok an idea - need an audio engineer to create an audio file that can be shaped and combined with priming to say the name of the playing card the spectator is "thinking" of.
Maybe the audio file will need to be slowed down, sped up, or tone changed, or maybe there needs to be multiple o**s with the performer swapping the audio file played in some way.
It would be cool to force a set of playing cards on more than one spectator, then have them each hear their card from the same audio file being played....

Something like this would be fairly easy to do. One recent scientific learning is that We can understand audio which has been clipped to only include the high points. But the interesting thing is that we generally only understand it when it is primed, that is we know what is being played. An example of this is the "speaking piano" where you can hear the voices when you know the song lyrics or the lyrics are displayed. See here for example:



A selected card should work as a prime for the person who selected it but not others. See here at 3 minutes 10 seconds for an explanation.

Great stuff! Thanks Frank.
