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?

Recently a “Framework for Success in Postsecondary Writing” came out in the U.S. This framework talked about the importance of inculcating certain “habits of mind” in students. One of these eight habits was metacognition, which they defined as the ability to reflect on one’s own thinking as well as on the individual and cultural processes used to structure knowledge.
How many words do you need to learn?
An analysis of English vocabulary* has found that the first 1000 words account for 84.3% of the words used in conversation, 82.3% of the words encountered in fiction, 75.6% of the words in newspapers, and 73.5% of the words in academic texts. The second 1000 accounts for about another 5% (specifically, 6% of conversation, 5.1% of fiction, 4.7% of newspapers, 4.6% of academic texts).
Context is absolutely critical to successful communication. Think of the common experience of being a stranger at a family gathering or a meeting of close friends. Even familiar words and phrases may take on a different or additional meaning, among people who have a shared history. Many jokes and comments will be completely unintelligible, though you all speak the same language.
Visual Language, a term introduced by Robert Horn, refers to "language based on tight integration of words and visual elements". The visual elements include shapes, as well as images (e.g., icons, clip art).
What does this have to do with memory? Well, partly of course, because the appropriate use of images usually makes information more memorable, but visual language has considerably more to offer than that. To appreciate what it is, Horn has examples at http://web.stanford.edu/~rhorn/
Here’s an interesting study that’s just been reported: 72 seven- and eight-month-old infants watched video animations of familiar fun items being revealed from behind a set of colorful boxes (see the 3-minute YouTube video).
Does emotion help us remember? That's not an easy question to answer, which is unsurprising when you consider the complexities of emotion.
First of all, there are two, quite different, elements to this question. The first concerns the emotional content of the information you want to remember. The second concerns the effect of your emotional state on your learning and remembering.
The effect of emotional content
It does seem clear that, as a general rule, we remember emotionally charged events better than boring ones.
Subliminal learning achieved notoriety back in 1957, when James Vicary claimed moviegoers could be induced to buy popcorn and Coca-Cola through the use of messages that flashed on the screen too quickly to be seen. The claim was later shown to be false, but though the idea that people can be brainwashed by the use of such techniques has been disproven (there was quite a bit of hysteria about the notion at the time), that doesn’t mean the idea of subliminal learning is crazy.
There was an alarming article recently in the Guardian newspaper. It said that in the UK, diabetes is now nearly four times as common as all forms of cancer combined. Some 3.6 million people in the UK are thought to have type 2 diabetes (2.8 are diagnosed, but there’s thought to be a large number undiagnosed) and nearly twice as many people are at high risk of developing it. The bit that really stunned me? Diabetes costs the health service roughly 10% of its entire budget.
Frances Yates described the memory strategy valued by the ancient Greeks and Romans as the "Art of Memory" in her widely quoted and seminal book The Art of Memory. Today we know it as the method of loci. But the Art of Memory, as those of the ancient world and those of the medieval world practiced it, is far richer than is implied by that title.
