Evidence for visually different presentation format

The materials I am working on to train clinicians in risk assessment involve visual maps which I present using Mindmanager. I have blogged about this learning tool before (here and here). Well...I haven't read the source research that this article from the Sidney Morning Herald is based on, but it looks like it provides data to back up the contention that people learn best by being presented visual stimuli that complement and enrich what the presenter is saying, rather than repeating or rewording it like many Powerpoint presentations or other handouts do.

Tip of the hat to LifeDev, where I first learned about this article.
