Research merry-go-round up

I've been sitting on a number of research/news snippets which are all interesting but demonstrate how fluid the respective fields of neuroscience, cognitive psychology and educational study are. Sometimes it's hard to draw immediately practical inferences. Things are moving so fast that you can move from positions of contradiction, congruence and back to contradiction in a matter of days. This can be confusing, especially when you throw in the usual journalist demand for a sensationalist angle.

These recent headlines are a case in point:

Brain training claims dismissed

A Which? report states the obvious around some popular brain training software such as those from Nintendo, Lumosity and Mindweavers. It's still too early for anyone to claim categorically that their tools can, in isolation, lead to improved cognitive function. Other environmental factors always play a key role, which makes conclusive studies difficult.

Knitting can delay memory loss

A US study supports engaging in a hobby prevents memory problems later in life (by 40%). Keeping physically and mentally active is the key message - again stating the obvious perhaps?

Texting improves language skills

A positive report that "textisms" could be having a beneficial effect on reading development. Also the University of Toronto found instant messaging had a positive effect on teenagers' command of language.

Social websites: bad for kids' brains?

A number of reports alleging that online networking and gaming have health risks. Susan Greenfield weighs in on the debate stating that young brains may be fundamentally altered by internet activity - which is again fairly obvious. Why just young brains? Old brains are (almost) just as plastic. For more on this, Donald Clark does a great job of putting her expert opinion under critical review.

Digging deeper

With all this potential for confusion I find it's important to trace things back to their sources where-ever possible as there are usually more solid nuggets of information to be found. I'll leave you with one interesting piece on a subject I've posted on before - memory and sleep. In this study, it has been found that stages of sleep have distinct influence on the process of learning and memory. Communication between the hippocampus and prefrontal cortex appears to change when moving between SWS and REM sleep. When disconnected (as it is during REM sleep) you are more likely to forget newly formed memories, explaining perhaps why most dreams are forgotten.

The Five Minute University



Harold Jarche referenced this delicious video clip of Father Guido Sarduci pointing out what we all know about traditional schooling and higher education - we forget most of it. So what is the net value to us and society in perpetuating a model that is plainly inefficient, especially when the connected world we live in now fundamentally changes the economics on which that model was based.

As I've said before in one of my original posts to this blog: Less Learning, More Often is a conceptual framework that goes someway to address this chasm.

By the way - get to the end of the clip. The legal profession is vastly over engineered and at some point must undergo disruptive change once we remove the archaic language and democratise access to the computer systems and databases that many lawyers rely on anyway. E-learning can play a big role in helping society better understand the laws of the land.

Snooze and Learn Faster



A recent study has found that a ninety minute daytime nap helps speed up the process of long term memory consolidation.

The group that slept in the afternoon showed a distinct improvement in their task performance by that evening, as opposed to the group that stayed awake, which did not exhibit any improvement. Following an entire night's sleep, both groups exhibited the same skill level.

The study indicated that the brain could successfully consolidate new memories in a 90 minute period rather than the normal 6-8 hour overnight sleep. So our international friends that love their siestas may well be learning faster and forgetting less than those of us who stay up and only sleep for one session a day.

Perhaps we'll see some brave face to face trainers including an enforced "sleep break" into the day's agenda to take advantage of this effect. Another example of the positive effects of less learning more often!
