Our brains have separate short-term memory buffers for audio and visual signals. The audio buffer is much stronger when dealing with language.
That statement – which is based on research by Alan Baddeley, Catherine Penny, and other cognitive psychologists – reinforces something I have believed for many years: educators and technologists undervalue the impact of audio.
We spend a great deal of time creating videos, almost to the complete exclusion of audio recordings. Sound files are much easier to record and edit – not to mention the fact that they are smaller and thus quicker to load. Now we know that sound is just as effective – if not moreso – than videos or still images. Give sound-only a try; we’ve published some posts on this blog that may help.
