Super-Smart Learning

For a scientifically inclined utopian, technology is the potential antidote to all of society’s ills. Techno-optimists believe every challenge, from cancer to cleanliness, has an applied-science solution. Most of us approach technology with significantly more skepticism, of course. But as 21st-century citizens, we’ve come to understand that our progressively more complex problems require more than machines alone.

As it turns out, though, simpler challenges—like, say, memorizing the names of world capitals—are in fact being better addressed by new technologies every day. So goes the story behind two learning programs, and SuperMemo, both garnering attention as we increasingly look to gadgets and gizmos to improve our lifestyles. (Call it the Wii Fit phenomenon.) and SuperMemo aim, and claim, to help you memorize and retain knowledge in more efficient ways. Both products are based on a well-proven finding known as the Ebbinghaus, or forgetting, curve, first deduced by German psychologist Hermann Ebbinghaus in 1885. The curve is an equation (R=e^{-frac{t}{S}}, to be specific) that describes how our brains forget things over time.

Essentially, Ebbinghaus found that memory retention of newly acquired knowledge declines unless we consciously review that knowledge. Subsequent scientific studies (mostly in the 1930s and late 1960s) revealed even more about the nature of memory and learning: If we review an item right before we’re about to forget it, immediately prior to our brains’ contact with the curve, we actually improve our ability to retain that item in memory. The way to ensure remembrance, then, is to increase the length of time between these information reviews, a technique otherwise known as spaced repetition.

When computers became more common in the 1980s, researchers began to experiment with algorithms for automating the spacing of repeated knowledge over time.

Fast forward to the future and the tantalizing promises of technology for better living. Just as exercise has its own digital assistant, so too can learning. If all it takes to remember something is a well-timed reminder, then why not leave your learning to a robot? And now not only can we automate such simple processes, we can make them fit in the palm of a hand.‘s newly released iPhone app promises to do just that — make learning a portable experience — as illustrated in a cheeky short its creators made to highlight the app’s features and functionality.

The iPhone app is based on‘s online-learning platform, which itself grew out of an adaptive-learning system called iKnow. Cerego, a Japanese venture-backed think tank, created all of the products and had already popularized iKnow’s use in Japan before introducing an English-language version. We were fascinated to see how this earlier incarnation of developed into its intuitive, present-day user experience, a process satisfyingly documented as a case study by the über-smart design firm Adaptive Path, which partnered with Cerego on these multiple orders of translation.

Where is sexy and supple in design, SuperMemo is, well, not. (Consider it the Craig’s List of online learning.) What it does have, however, is a storied pedigree documented by Wired and other ahead-of-the-curve pubs (pun unfortunately intended). SuperMemo‘s creator, Piotr Wozniak, is its ultimate evangelist because he’s also its Ur-user — he created the platform for his personal use. Wozniak developed the software behind SuperMemo in the mid-1980s without prior knowledge of Ebbinghaus’s repetitive trials. Its user interface seems like it’s changed little since Wozniak wrote his first programs, but perhaps this is SuperMemo‘s charm. In fact, a kind of cottage industry of both white-label versions and ad-hoc, pirated programs sprang up as soon as the Internet allowed for easy file sharing.

What hides under the hood, however, SuperMemo makes accessible. All of the statistical breakdowns driving the program’s prompts are available for your perusal, should you get excited by indices and intervals. (No need to be shy–we’re very sympathetic to such symptoms here at Brain Pickings.) For the person who wants to see and directly manipulate a product’s inner workings, SuperMemo allows for much more hands-on interaction than the plug-and-play approach designed by Adaptive Path. What both and SuperMemo share is a pliability in their ultimate purposes. You can use preprogrammed language-learning modules, but you can also personalize each by adding your own information for spaced repetition.

So while neither nor SuperMemo can cure the common cold, consider exploring technologically augmented learning for your next mental exercise–like that taxonomy of Tolkein characters you’ve been meaning to commit to memory.
