But what's the point of memorizing things anyway? It doen't really indicate you are smart. I believe it is more important to be able to figure things out than to instantly reproduce them from memory.
I agree that most of the time, it's much better to understand than to just memorize and regurgitate. However, memorization does occassionally come in handy, for things like timed tests where you don't have the time to work out everything from scratch, or just for remembering lists of things to do.
This thread triggered me to remember a seminar I attended a year or two ago. The person presenting had done some studies of what parts of the brain are used when we remember numbers and letters, faces, etc. There were some interesting things that came out of it...like it's harder to remember a list if it is mixed numbers and letters. If it's mostly numbers, you'll remember the numbers and not remember the letter in the middle of the list. And entirely different parts of the brain are used for different types of memorization tasks...faces, names, letters (words), numbers (zip codes). I'll look and see if I can find the name of the person who gave that talk and see if some of this has been published yet. If so, I'll post some references to look up. It was a pretty cool topic (at the end, I was left wondering if it had anything to do with why some people have such difficulty learning algebra, when letters are subsituted for numbers, it may be something that some people just can't connect).

Aha! Found it! This isn't exactly what I was mentioning above, but it's by the same group and is part of what was discussed at the seminar I attended. Here's an abstract of one of their papers that says us older people don't learn the same way as younger people

Actually, if I recall it correctly, I don't think I'm old enough for the "older" group in this study (I haven't gone back to read the full article yet).

Working memory for complex scenes: age differences in frontal and hippocampal activations.
Park DC, Welsh RC, Marshuetz C, Gutchess AH, Mikels J, Polk TA, Noll DC, Taylor SF.
Age differences in frontal and hippocampal activations in working memory were investigated during a maintenance and subsequent probe interval in an event-related fMRI design. Younger and older adults either viewed or maintained photographs of real-world scenes (extended visual or maintenance conditions) over a 4-sec interval before responding to a probe fragment from the studied picture. Behavioral accuracy was largely equivalent across age and conditions on the probe task, but underlying neural activations differed. Younger but not older adults showed increased left anterior hippocampal activations in the extended visual compared with the maintenance condition. On the subsequent probe interval, however, older adults showed more left and right inferior frontal activations than younger adults. The increased frontal activations at probe in older adults may have been compensatory for the decreased hippocampal activations during maintenance, but alternatively could have reflected the increased difficulty of the probe task for the older subjects. Thus, we demonstrate qualitatively different engagement of both frontal and hippocampal structures in older adults in a working memory task, despite behavioral equivalence.
