The best form of ‘cognitive housekeeping’ is to sleep on it.

Visible to anyone in the world

So I blogged three months ago when considering the merits and demerits of keeping a learning journal and reflective writing.

It transpires that sleep really does sort the ‘memory wheat from the chaff’ according to a report in the Journal of Neuroscience, DOI, 10,1,1523.jneuorsci.3575-10.2011) referred to in the current New Scientist. This Week. 5 FEB 2011.

‘It turns out that during sleep the brain specifically preserves nuggets of thought it previously tagged as important.’ Ferris Jabr says.

I have always used sleep to reflect on ideas.

If I expect or wish to actively dwell on something I will go to sleep with the final thought on my mind, a pen and pad of paper by my side. Cat naps are good for this too. I will position myself with pillows and a book, or article and drift off as I finish. Waking up ten or twenty minutes later I glance straight back at the page and will feel a greater connection with it.

I wonder if there is commercial value in working from home and doing so up 'til the point you need to fall asleep? It's how my wife works when she is compiling a hefty report. It's how I work when I have an assignment, or a script to deliver ... or a producton to complete. The work never stops and it doesn't stop me sleeping.

Going back to tagging.

How does the mind do this? In curious ways. We all know how a memory can be tagged with a smell or a sound. For me how mothballs remind me of my Granny’s cupboard (an image of it immediately in my mind). A Kenwood blender will always remind me of my mother grings biscuits to put on the basae of a cheesecake. And a sherbert dip the Caravan Shop, Beadnell, Northumberland. Often when a random recollection enters my consciousness I try to think what has triggered it: the way the light falls on a tree, the exhaust from a car or even a slight discomfort in my stomach. It is random. Indeed, is a random thought not impossible?

There has to be a trigger, surely?

Can any of these be used?

Perhaps I could categorise content here, or in an eportfolio by taste. So chocolate digestive biscuits might be used to recall anecdotes. Toothpaste might be used to recall statistics. Varieties of Bassett’s Liquorice Allsorts might be associated with people I have got to know (a bit) during the MAODE.

The mind boggles; or at least mine does.

Colour and images (Still or moving) is as much as we can do so far.

I’m intrigued by memory games. I like the journey around a familiar setting where you place objects you need to remember in familiar places so that you can recall a list of things. Here the tag is somewhere familiar juxtaposed with the fresh information.

Are there better ways to tag?

Look at my ridiculously long list of tags here. Am I being obtuse? When I think of a tag do I come up with a word I've not yet used? How conducive is that to recalling this entry, or grouping similar entries to do the job?

I like the way some blogs (Wordpress/EduBlogs) prompt you to use a tag you’ve applied before; it offers some order to it all. I long ago lost track of the 17000 entries in my blog. Would I want to categorise them all anyhow? I think I managed 37. I prefer the 'enter@random' button I installed.

Going back to this idea of tagging by taste/smell, might a word (the category) be given division by taste/smell, texture and colour? How though would such categories work in a digital form? Am all I doing here recreating a person’s shed, stuff shoved under their bed or stacked in a garage, or put in a trunk or tuck box in the attic?

In the test reported in the Neuroscientist those who went to bed in the knowledge that they would be tested on the information they had looked at that day had a 12% better recall.

See.

Testing works.

It doesn’t happen in MAODE, if at all. When are we put on the spot? When are we expected ever to playback a definition under ‘duress’?

‘There is an active memory process during sleep that selects certain memories and puts them in long-term storage.’


Like an e-portfolio?

Is the amount of sleep I've had, the 350 or so nights since I started the MAODE ... part of the learning environment required?
