And Slaters Go Plop

Here’s an interesting phenomenon. Watch the video through before continuing to read these comments.

Once you’ve watched it through, press replay and close your eyes.

I heard about this on a recent Quirks and Quarks podcast. The talking head is filmed saying “Ga ga ga ga” and is overdubbed with the sound of him saying “Ba ba ba ba”. Because our visual and aural senses work in tandem and our brain is really good at trying to make sense of things we will ‘hear’ the guy on the video saying “Da da da da”. This is true of just about any other kind of illusion. Our brains help us out by pre-rendering things we see, hear, smell, touch and taste. Sometimes our brains can be tricked and this is one of those times.
