Let’s talk about the cognitive benefits of learning and using another language.

In a recent news report, I talked about the finding that intensive learning of a very novel language significantly grew several brain regions, of which two were positively associated with language proficiency. These regions were the right hippocampus and the left superior temporal gyrus. Growth of the first of these probably reflects the learning of a great many new words, and the second may reflect heavy use of the phonological loop (a part of working memory).

Song is a wonderful way to remember information, although some songs are better than others. Songs that help you remember need to have simple tunes, with a lot of repetition -- although a more complex tune can be used if it is very familiar. Most importantly, the words should be closely tied to the tune, so that it provides information about the text, such as line and syllable length. You can read more about this in my article on Music as a mnemonic aid, but here I simply want to mention a few specific songs designed for teaching facts.

A new book, Moonwalking with Einstein: The Art and Science of Remembering Everything, has been creating some buzz recently.

Transfer refers to the ability to extend (transfer) learning from one situation to another. For example, knowing how to play the piano doesn’t (I assume) help you play the tuba, but presumably is a great help if you decide to take up the harpsichord or organ. Similarly, I’ve found my knowledge of Latin and French a great help in learning Spanish, but no help at all in learning Japanese.

In general, the weight of the research evidence suggests that college students tend to have a poor sense of how prepared they are for testing, and having been tested, they have a poor sense of how well they did! (This, of course, is even more true of younger students).

Does it matter?

Find out about the pegword mnemonic

Here are pegwords I've thought up in the Spanish language.

As with the original example, let's try it out with our cranial nerves.

En español, los nervios craneales son:

We must believe that groups produce better results than individuals — why else do we have so many “teams” in the workplace, and so many meetings. But many of us also, of course, hold the opposite belief: that most meetings are a waste of time; that teams might be better for some tasks (and for other people!), but not for all tasks. So what do we know about the circumstances that make groups better value?

Most cognitive processes decline with age

It does appear that most component processes of cognition decline with advanced age if the difficulty level is sufficiently high. For example, the following processes have all shown age effects:

Alzheimer's disease currently affects one in 10 people over age 65 and nearly half of those over age 85.

More than 19 million Americans say they have a family member with the disease, and 37 million say they know somebody affected with Alzheimer's.

In the United States, the average lifetime cost per Alzheimer patient is US$174,000. (These figures are from the U.S. Alzheimer's Association).

In the mid-seventies, Raugh and Atkinson had remarkable results using the keyword method to teach Russian vocabulary to college students. While later studies have not tended to find such dramatic results, nevertheless, a large number of studies have demonstrated an advantage in using the keyword mnemonic to learn vocabulary.

Some researchers have become huge fans of the strategy. Others have suggested a number of limitations. Let’s look at these.
