Many parents enrol their children in Montessori preschools because they are an "educational" way of getting childminding - if you're going to put your child in a creche, why not put them in a preschool instead - or because they want to give their child a "head start" on education. Quality preschool education is a rarity and Montessori are certainly leaders in the field.

Brain tissue is divided into two types: gray matter and white matter. These names derive very simply from their appearance to the naked eye. Gray matter is made up of the cell bodies of nerve cells. White matter is made up of the long filaments that extend from the cell bodies - the "telephone wires" of the neuronal network, transmitting the electrical signals that carry the messages between neurons.

The volume of gray matter tissue - a measure you will see cited in various reports - is a measure of the density of brain cells in a particular region.

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 thing to remember about Ericsson’s famous expertise research, showing us the vital importance of deliberate practice in making an expert, is that it was challenging the long-dominant view that natural-born talent is all-important. But Gladwell’s popularizing of Ericsson’s “10,000 hours” overstates the case, and of course people are only too keen to believe that any height is achievable if you just work hard enough.

The much more believable story is that, yes, practice is vital — a great deal of the right sort of practice — but we can’t disavow “natural” abilities entirely.

Humans have a long tradition of holding genes responsible for individual differences in behavior (of course, we called it "blood", then, or "family"). In the 20th century, a counter-belief arose: that it was all down to environment, to upbringing. In more recent decades, we have become increasingly aware of how tightly and complexly genes and environment are entwined.

"Consolidation" is a term that is bandied about a lot in recent memory research. Here's my take on what it means.

Becoming a memory

Initially, information is thought to be encoded as patterns of neural activity — cells "talking" to each other. Later, the information is coded in more persistent molecular or structural formats (e.g., the formation of new synapses). It has been assumed that once this occurs, the memory is "fixed" — a permanent, unchanging, representation.

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?

Two large-scale international studies have become established to compare countries' performance in the core subjects of literacy, mathematics and science.

TIMSS: Trends in International Mathematics and Science Study

TIMSS is an international study involving 50 countries that assesses math and science achievement at four year intervals. It has been running since 1995. Students are assessed in the 4th and 8th years of school, and in their final year. The next assessment round will be in 2007.

K. Anders Ericsson, the guru of research into expertise, makes a very convincing case for the absolutely critical importance of what he terms “deliberate practice”, and the minimal role of what is commonly termed “talent”. I have written about this question of talent and also about the principles of expertise. Here I would like to talk briefly about Ericsson’s concept of deliberate practice.

Autobiographical memory contains the information you have about yourself. It includes several domains:
