Back in 2010, I read a charming article in the New York Times about a bunch of neuroscientists bravely disentangling themselves from their technology (email, cellphones, laptops, …) and going into the wilderness (rafting down the San Juan River) in order to get a better understanding of how heavy use of digital technology might change the way we think, and whether we can reverse the problem by immersing ourselves in nature.

The Proto-Indo-European language (PIE) is the ultimate ancestor of many European and Indian languages. The word "proto" indicates it was spoken thousands of years in the past and we have no direct record of it. What we do have is the clear evidence in its descendant languages, from the consistent patterns in the way their words vary, that there was such an ancestor. Following these patterns, scholars have deduced a quite extensive vocabulary — but they are still reconstructed, not ‘real’ words. We can never know exactly how these words were pronounced, or precisely how they were used.
In the last part I talked about retrieval structures and their role in understanding what you’re reading. As promised, this month I’m going to focus on understanding scientific text in particular, and how it differs from narrative text.
Knowing a number of effective strategies for reading and note-taking, practicing and memorizing, is vital, but it's not the whole story. There is also a category of strategies we might term 'support' strategies. These include strategies aimed at setting goals, managing time and effort, and monitoring your performance and progress. In study, these come under the concept of self-regulation, which is related to the more general concept of metamemory.
To use note-taking effectively, you need to understand that its primary value is not in the record you produce, it is in the process itself. The process of taking notes guides the memory codes you make. Note-taking is a strategy for making information meaningful. It is therefore only effective to the extent that you paraphrase, organize and make sense of the information while taking notes.
Having trouble sleeping is perfectly normal, especially as we age. It’s estimated that half of those older than 55 have trouble getting to sleep or staying asleep.
What to do if your sleep is poor
Let’s start with the easiest situation: you’re not getting enough sleep because you wilfully go to bed too late to achieve your needs.
What is neurogenesis?
Neurogenesis — the creation of new brain cells — occurs of course at a great rate in the very young. For a long time, it was not thought to occur in adult brains — once you were grown, it was thought, all you could do was watch your brain cells die!
Adult neurogenesis (the creation of new brain cells in adult brains) was first discovered in 1965, but only recently has it been accepted as a general phenomenon that occurs in many species, including humans (1998).
Short-term vs long-term memory
Working memory is a relatively recent term, a refinement of an older concept - that of short-term memory. Short-term memory was called thus to distinguish it from "long-term memory" - your memory store.
Stimulating activities
A 5-year study1 involving 488 people age 75 to 85 found that, for the 101 people who developed dementia, the greater the number of stimulating activities (reading, writing, doing crossword puzzles, playing board or card games, having group discussions, and playing music) they engaged in, the longer rapid memory loss was delayed. Similarly, a study2 involving 1321 randomly selected people aged 70 to 89, of whom 197 had mild cognitive impairment, has found that reading books, playing games, participating in compute
As we all know, we are living in a time of great changes in education and (in its broadest sense) information technology. In order to swim in these new seas, we and our children need to master new forms of literacy. In this and the next three posts, I want to explore some of the concepts, applications, and experiments that bear on this.
