TBF018 – Dual Code Theory. Eyes and Ears.

  • SumoMe

This episode we discuss the benefits and proper ways to include audio with your visual presentations (read ‘PowerPoint’).

Dual Code Theory was originally purposed by Alan Paivio, a former Mr.Canada, in 1971.  I won’t be able to do the science justice, but the theory basically states that humans create memories through two channels, visual and audio.  For a more comprehensive description of the science head over to this link at Stanford. This was a the quote I read during the podcast.

Once again, we found a tie-in to my new favourite book, Made to Stick, and their Velcro Theory of Memory.  The idea being that the more thoughts we can associate a memory the easier it will be to remember it.  Sooo….if we are only reading a text book, it may not stick.  BUT! If we read a text book, listen to a discussion, and create a model with out own two hands, we have lots of memories to draw on when we need to recall that information.

In a recent blog post I discussed how we can make Compliance Training better.  We shouldn’t treat important information as unimportant and compliance training needs to be re-vamped to highlight the importance of it. We need to show the learner Whats In It For Them.  If we make the content more engaging by adding an audio element, learners may follow the bouncing compliance ball a little longer.  I made reference to the ‘7X7’ rule for creating slides and I got that from Groundwire.

I want to be clear that we shouldn’t simply be creating an audio version of what is on the screen.  This will only encourage learners to either turn the audio off or not look at the slides and we’re back down to a single sensory experience.  We should eliminate all non-essential words from the slides and use the audio to flesh out the ideas in the listeners mind.

Once again, we’ve found a bit of common sense that isn’t being observed.
