I am mostly a visual learner. If someone tells me to do something, it may possibly travel into one ear, out the other ear, and right into the air. However, if that same person sends me an email with instructions - then I see it - and I read it - and I usually remember it. It's even better with pictures or graphs or charts.
A picture of all the buttons (and what they do) on a game system provides more meaning than written instructions ... and WAY more meaning than verbal instructions.
Here's some great dictionary web sites for visual learners (like me):
Meriam Visual Dictionary - This dictionary site shows detailed pictures with callouts or descriptions of the word you search on. I love this web site and wish it had more.
Visuwords Online This web site is a dictionary. And a thesaurus!
You enter a word and the word with its origins and connections appear in bubbles that you can zoom in on or move around.
