Hi Folks,

There's an audio clip out there which can be heard as one of two words. Which of the words seems to be akin to handedness.

There's another clip out there, more recent finding, which can be heard as two of four or five words. Really. And which words you hear seems to depend upon which words you were expecting to hear at that instant. Change what you expect and the words seem to change.

I didn't name the words or directly link to the clip which includes the words so you an experiment with the clips without interference. If I get a chance I'll try and capture the clips and post links to clean samples so you can experiment.

What do you think?

I've yet to find approved sources for the audio - (nor eager to excerpt the audio from other people's video for teaching purposes) - but in the mean time here's a visual example of phenomenon:
