I've been fascinated in Ebbinghaus ever since the OU introduced me to his work. I've come to believe that this is a generalisation. Like all populations there are outliers: in this case, those who are better able to hold onto information and those who are not. I am on the 'do not' end of the scale. A lecture or class followed by review and homework and testing, then further prompts and exams worked for me. Anything less and I lose it. I don't concentrate enough in the class or lecture anyway, even note taking becomes mechanical.

This work offers explanations and methods.

REad the short paper by 'The Forgetting Curve' by Dr John Whitman 

Fig.1. My mash-up from the Start Writing Fiction, OU and FutureLearn MOOC. 

Many weeks after the Open University MOOC on Future Learn closed 'Start Writing Fiction' I find I am returning to the many activities across the eight weeks to refresh, reflect, and build on my knowledge. As well as doing my bit for that 'community' by doing a few reviews (all assignments are peer reviewed). I completed the course in early December.

I return to reflect, to develop ideas, to be reminded of the excellent lessons I have learnt there, and in particular on how we use fact and fiction, whether consciously or not. In pure fantasy writing I find, inevitably, that I ground events in places I know from my youth, or have since researched. I use the hook of reality and my experiences on which to build the fiction. While currently I am embedded in what started as 90/10 fiction to fact I find it is increasingly looking like 95/5 in favour of fact as my imagination is close to the truth about a particular character and his experience of the First World War. All this from a simple exercise in week one called 'Fact or Fiction?' where we are asked first of all two write something that contains three factual elements and one fiction, and then to write something that contains three fictional elements and one factual. There are thousands of these now, many very funny, original or captivating. In week one, I'm guessing that around 10,000 got through the week. How many posted? There are 967 comments. This happens. It is an open course. The same applies for most web content: 95:5 is the ratio of readers to writers. Many people prefer not to do what they feel is 'exposing themselves' online. Why should they.

Anyway, this gives me reason to argue that it is an excellent idea to keep a blog of your OU studies. All of this can remain private, but at least, as I know have in this blog, when the doors close behind a module you can, months, even years later, return to key activities and assignments and build on the lessons you learnt. More importantly, as we all forget with such ease, we can keep the memory of the lessons fresh.

Fig.1. The contents of your learning journal, or e-portfolio or blog could look like this

As I'm prompted to do so, or is this just a MAC thing? I now tag documents downloaded to my desktop. They can be found wherever I or the operating system has buried them.

I tag religiously here (except, since a month ago, when writing from my iPad as it crashes the page and the iPad ?!).

I tag for a number of reasons:

I jot down ideas and thoughts, facts, even grab, cut and paste stuff that may be of use later so tag it so that I can tickle it out later as the mood or need fancies.

By tagging by module, and by activity you can then regularly go back and add a further tag as you plan a TMA (tutor marked assignment) or EMA (end of module assignment). For example, L120 is my current module. I will (or should) add L120A1 perhaps or L120S1 to identify an activity or session (NOT necessarily shared at all if I am giving away answers potentially or breaching copyright too blatantly by privately 'curating' content). Potentially L120TMA1 obviously helps me pull out content pertinent to this. That's the idea anyhow. The OU used to have an e-portfolio called MyStuff, a bit clunky, but it did this and then allowed you to re-shuffled the deck as it were, to give order to the things you picked. In theory you then have a running order for an assignment.

Tag clouds, number of tags or simply the weight and size of the font, indicates the strength and frequency of certain themes and ideas. When playing with the idea of an 'A-to-Z of e-learning' it was easier for me to see, under each letter, what I ought to select ... and then immediately have a load of examples, some academic, some anecdotal, all personal to me, at hand.

I come here to find things I've lost! Amongst 20,000 saved images I know I have a set from early training as a Games Volunteer for the London Olympics. I searched here, clicked on the image and thus found the album in Picasa Web (now Google Pics). Why can't I do that in my picture/photo pages? Because I never tagged the stuff. There is no reliable search based on a visual - yet.

No one can or should do this for you.

My blog and e-portfolio is fundamentally and absolutely of greatest value to me alone. So why allow or encourage others to rummage in the cupboards of my brain? Because it tickles and stimulates me to share views, find common or opposing views and to believe that others are getting something from it.

Fig.1 Does alcohol have a permanent effect on the brain?

The answer is 'yes', though of course it is dependant on many variables: binge drinking is bad, like a blow to the head. This comprehensive heavy-weight article I Googled, 'Alcohol's Damaging Effects on the Brain' satisfies my initial curiosity, then the above shocking image catches my eye.

Dare I ask if we know any child who clearly showed such facial traits?

Far too late to do anything about it though.

After this paper like post from the National Institute of Alcohol Abuse and Alcoholism I eventually start looking to chase up a few references (the very best way to satisfy you curiosity and layer detail onto the ideas you are gathering) when I read that 'memory formation and retrieval are highly influenced by factors such as attention and motivation'.

From E-Learning V

This quote from Kensinger E A et al in the Journal of Neuroscience 2003. Title: What neural correlates underlie successful encoding and retrieval? Not Found in the OU Library so I cut and paste into Google Scholar and there it is to download as a PDF.

It is not surprising that scientific research shows (not speculation) that distraction diminishes attention and therefore retention, nor surprising that a low level distraction has less impact than a high one.

Does a teenager (or any of us) supposedly doing homework while

a) interacting on Facebook

b) answering text messages

c) streaming a movie and/or

d) playing a video game

... complete a task half as well than when focused?

Exam conditions aren't just best for exams:

turn off the radio and phone, shut the door, put up a 'Do Not Disturb' sign, give yourself a set period of time in which to concentrate ... and reward yourself at the end of it (not with alcohol though).

Why we all need a 'room of our own'? (Even if you have to wait until someone else vacates it).

Better an hour studying when motivated and focused, then three hours while streaming a movie, or answering email?

 Fig.1. Yours truly - demo tape - age 19

The idea that something hanging around our neck will record our every moment, store, and log it sounds absurd, counterproductive and misses the point about memory formation and the value of forgetting so that you can interpret the past as you like through anecdotes and storytelling. In this BBC 4 Radio programme on memory one character suggested that a grandchild asking his grandfather how he met his grandmother could look at the real playback instead of hearing the story.

I'd gladly forget the above tape: a teen attempt at rockstardom (not). A bunch of hideous songs that I play abd sing to. Cringeworthy. Some things are best forgotten, even buried, certainly not stored.

I'd forgotten how much the topic fascinated me so will in due course dig through everything I've put down on it in the past and see what fresh angle I can come up with. I particularly like the metaphor of 'sedimentation' to describe a way forward to layer digital information stored on us, that is is buried in the virtual sense, under and in layers of other information. This tape (digitised rather foolishly) would then be stored as some kind of fossil - it would be stored, but not readily available as it were.

Thanks for the Memory, In Business.

Peter Day Thursday 4th and Sunday 7th September

BBC Radio 4 

The power of serendipity.

At 21:33 last night my wife called from a rural train station. Apologising for being 'like my late Mum', she said there was something on the radio that might interest me. And so, 12 hours later I am about to listen to this for the FOURTH time. This isn’t because of its academic value per se, rather for its irritation factor. Going by the online monnica of ‘MindBursts’ for the best part of a decade hints at where my latent, longterm interests lie. What a mess and joy ‘natural’ memory can be; I’m yet to see an algorithm deliver credible serendipity. When did my mother last call me in this way? She died exactly two years ago. It would have to be about three to two and a half years ago and most likely would have been Samuel Pepys dramatised for radio, or the hints then of the content that is now flooding the airwaves on the First World War.  Letting that memory fizzle, reform and sink back into my brain. Does this programme trivialise or simply ignore the complexity of the brain? No neuroscientist was interviewed. Shame. 

Very often the BBC and Peter Day et al get it right, but here the researchers and writers have got horribly lost, like a kid on their first visit to a fairground they have run about picking up hifhafultiing fag ends, being impressed by trivia, while occasionally calling in an academic or business big hitter. My concentration lapses on each time of listening after 15, then 20, then 25 minutes. The FIFTH and SIXTH listening my start in the middle. What these programme need, regardless of accessibility needs, is a transcript. I could have got this in a couple of sittings by listening to Peter Day while reading the transcript.

There is value in imperfection. There is value in being irritated by a programme. Had this been a lecture I would have had a list of questions at the end, I may even have heckled or muttered my annoyance along the way.

What a hotchpotch.

There are problems of audience, intent, journalist sensationalism, taking such a random and ranging set of examples and setting them as if they warrant or deserve to share the same platform. 

It begins with something that would have a live audience listening to a stand-up comic nodding in agreement: our no longer having phone numbers in our head. Why would we try to recall the complex and the trivia, an area code as a name with and three digit number, say Wideopen 3119 (my home phone when I was a kid) is easy; not so easy, especially after repeated additions and alterations are the lengthy and multiple contacts we have today. And what was wrong with the pocket address book in its day? It wasn't a case of remembering a phone number, so much as remembering where we'd put our address book.

Technology is there to manage our memories. Luciano Floridi

"It's as radical as looking at the difference between the roots of a tree and the petals of a flower".

This is the man who should have carried the programme; instead we get a soundbite at the start and another at the end. As bookends his profound thoughts barely tether this piece. Perhaps it just tries far too hard to cover everything in a myriad of ways and ends up trying to catch smoke rings in its fingers?

We hear from:

Evernote: set up six years ago, a series of digital tools to help people remember everything. Research. Communicate. To visually communicate what you mean. Phil Libbin,

Timehop set up by Jonathan Wegener. The idea is to milk what people put into Facebook. He has big financial backers. Timehop replays a day at a time a year ago, ten years ago, drawing from Facebook. He suggests that ‘old is awesome’. Aimed at getting users, not revenue. Will make money ‘when the time is ripe’. I find it dubious and ethically immoral, even inept naive views of how people want the serendipity of forming and reforming their own memories. His game plan can only be to sell to Facebook. I quit Facebook recently and doubt I will ever return. Far, far, far to invasive and exploitative, and for me, distracting and addictive.

d3i, set up by Oliver Waters. He used to keep a ‘journal’ from ten up to university. So what. Millions do and many for far longer, and in a directed way, say keeping minutes of business meetings led to Linkedin. The key, he thinks, is not keeping the diary yourself. WRONG. D3i is dependent on the nonsense and ephemera that people put into Facebook. a) this Facebook dependence is dangerous and limiting b) a fraction of people are digitally literate or even care, or care to use social media very much c) students, by way of example, are shown to distinguish between their social, digital and student academic lives. My tip is to perhaps keep a dialy log, or diary. Perhaps restrict to a learning journal if you are studying. Or write a travel log for a trip. I have great fun looking at a diary I kept just for a French Exchange I did in my teens. Another for a gap year job in the alps for a season. 

Memoir. Lee Hoffmann. He suggests there is value in the trivia of social media. Such as sitting with a grandchild and they ask how you met and you show them rather than tell them. This is horrid. Far better to learn to tell stories and learn to listen to the story teller. Snapping away at the trivia of the day. Gross failing to understanding the nature, quality and accruing and sifting quality of storytelling. A few memories as a child of sitting on my grandfather's knees while he talked about the First World War would be reduced to ... her son, watch the video while I go and do something more useful with my time. Poppycock. If you take the human out of memory then it is counterproductive.

Rather

Improve what we have. All text with voice, all voice with transcripts, all video with text and audio grabs …. I’m unconvinced that the commercial operators have much understanding of how memory works. The company they failed to spot is QStream, which in a far more tailored, and valuable way, works with our propensity to forget to aid memory creation in the brain - which is where you need the information if you are to do anything original with it. 

The Problem

The need to filter and forget, far better to enhance or support memories that have value, rather than those that do not. So much is missed in this programme. The fundamental background understanding of memory and how and why we forget. 

We hear from:

Peter Baron, Google. He's asked to talk about European Court of Justice ‘take down’ law and the legal and social need to forget things like spent court convictions. 

European Data Protection Law

Then there's a thing called 'Chronicle of Life'

Facebook and Flickr, so long as they are profitable.

And someone called Milan Chetti, of Chief of Research at HP, Boston Maschatucets.

If I can spell these names correctly I'll find them online, see what the have to say and re-invent this piece for my own understanding of the situation. I ought also to revisit anything I've tagged: life logging, memory, forgetting and so on in here.

All this will take time that I'm prepared to put in to write an article, if not a paper. 

One of the profound impacts is that the memorisation process of the human brain has been altered already … constant reliance on mobile devices has hurt our short term memory as mankind, while digitisation of events over time can help recall and improve out long term memory. So short term memory being carried by devices, while long term memory is enhanced. So we forget directions and phone numbers as our devices do this for us, storing contact details and getting us from A to Z and home, while deeper.

Ki Commenenti - Chronicle of Life. To store data forever.

Spelling anyone?

What about life logging, what about problem solving, such as dementia, even assisting at school and in the workplace. The answer is smarter, personalised and mobile and AI.

If it can be done, it will be done.

Luciano Floridi (misspelled on the BBC website) again ... 

Innovation, Legislation … but understanding lagging behind

Reshape huge chunks of our lives in ways we haven’t understood.

From E-Learning V

Floridi uses the metaphor of sediments and layers, a better analogy, as it starts to create in the minds eye a complex environment, though as connected information, digital content changes as associations, reviews, use and comments accrue. I made the connection to Hjulstrom's Curve as I was helping my son get his head around this for A' Level geography last night. I dug out my own Geography text books but found nothing on Hjulstrom. This came from a considered search and selection online. I started to teach my 16 year old son how to do a more academic search online. His approach lacks so much finesse it is shocking. A few minutes of my TLC and we find a brilliant short video from an Irish Geography teacher that put it all so very well.

The programme annoys me because from Peter Day and the BBC you expect a far higher degree of scientific even academic certainty rather than something that is part the One Show for radio. Luciano Floridi of all those we hear from is the one to track down as he does what the very best academics do; they take the  complex and try to explain it based on sound research and a depth of experience that few of the others have.

A memory isn’t static, now is it tangible, it is a chemical construct of the moment that the human brain reinvents every time we recall a memory. All that we have experience since that event formed a memory impacts on how we recall it. To preserve an aspect of such an event digitally can never be a ‘memory’ : a photograph of your child’s third birthday doesn’t include the smell of candles and chocolate cake that reminds you of your own eighth birthday, or in my case that my father never attended a single birthday, not my birth, not my 21st … he turned up to say he was leaving. No figuring that. And immediately indicating how a memory is a shifting entity and if you think about it for long enough it is probably very personal.

Just because you can, does not mean it has value. For centuries people have kept diaries, but how many are a Samuel Pepys or an Anne Frank? It is the record of events so much as the interpretation and voice of the author sharing memories and consequences of these events. 

My rant not over. This is a subject that fascinates me. 'Mind Bursts' as a thought has been my external blog for seven years and with hints of something on the horizon I bought the dot com last year. 

The problem now, compared to ten years ago, is finding amongst millions people to talk to about this. Finding like-minds used to be so, so much easier before the Internet got out of hand and now deluges us with stuff, with too much commercialised and gamified content that gets in the way. 

If you listen to the end then perhaps 2020 will be the end - there won't be enough electricity generated in the world to store this digital content anymore. Hopefully it'll all implode, there'll be a massive clear out, and no doubt there'll be a healthy re-invention or return to books and photo albums.

Meanwhile, my memory-support system called this e-learning journal, blog, portfolio thingey offers up the following. The value of these tagged posts is that they are my interpretation of ideas from months or years ago that will trigger an aggregation or assimilation of fresh ideas and thoughts, something that can never occur simply by grabbing new, unknown stuff produced by others on the Interent. It matters that saved content connects with your soul, that intangible part of the brain that nothing digital can ever reach or approach at mimicking.

Fig. 1 Amongst the many official tributes a personal commemoration of three brothers killed in the First World War

Lewes memorial remembers some 360 names; they've been pinned to specific addresses within walking distance of the memorial. In Southover Ward for the 75th anniversary a book was published detailing the lives of each person - their school record, photo and home and other information, such as playing cricket for the local team or where they worked.

Fig.2. Lewes Town Hall War Memorial

Will anyone remember us a hundred years after we have died?

Just as it is important for us to forget as a learning process and challenge, should society forget, filter or edit? Does commemoration in glorify war with its nationalistic, militaristic and religious connotations?

Fig.1. Index Card Holder

An odd one this, but with my shift away from trying and expecting to do everything on an Internet connected device - nothing printed out, nothing written down, I have swung round to complimenting this 'screen work' with pads of paper, note books, a whiteboard and even index cards.

I'm currently sifting through all the possible causes of the First World War

I am collating notes from various books and having reduced these to eight themes in Google Docs I am now picking through these and putting them on index cards ... which in turn I want to develop as a series of carefully composed multiple-choice questions to put onto an online delivery platform such as Qstream and a mind-map.

I came across these in ASDA.

On special offer for £2, down from £4.50 I think. I may go and get some more as I like the idea of having a topic per Filofax-like binder. You might not have 60 key events/ideas or issues, but once in this wee binder they are, at low cost, portable and accessible - for me as I think through and prioritise a set of arguments, but for anyone with an exam, something to flick through repeatedly until the information sticks.

Playing Mercutio in 'Romeo & Juliet' 1983

Thirty years ago, possibly to the week, I performed in a university production of Romeo & Juliet as Mercutio. I've just been watching, to my horror, a digitised copy from the Betamax original.

That's me with the spindly legs in the white tights.

Not suprisingly, more so than a diary entry, this takes me to the moment. Minutes later the large nappy pin holding up my hose (the stuffed, bulbous pants) comes undone. I complete the fight to the death having pulled up my hose more than once - laughter and awareness rather spoils the moment and more liek Franky Howard than Shakespeare I die on the line 'A plague on my underpants'.

Fascinating that even in silhouette I would have recognised my teenage son in how I move.

My wife tells me I don't speak like that any more.

Cruel and revealing to me that I was so dependent on the director -  in this amateur production I minch about more like Malvolio from Twelfth Night.

My fascination in memory is pricked by this.

There is value in forgetting and not having a record of past events yet wearable technology is gradually making it possible to keep a record of everything we do - both visual and audio. Our perceptions are altered by the recalling of a memory. Though of course, this particular memory is still not my visual memory as my perspective will always be caught up in this scene.

REFERENCE

The power to remember and forget

Fig. 1. Looks a like a good read

I'm starting to read papers on neuroscience that result on my starting to use my hands and fingers as I read, even reading and re-reading phrases and sentences. What is going on here?

If I understand it correctly there is, because of the complexity of connections between neurones, a relationship with many parts of the brain simultaneously, some common to us all, some, amongst the millions of links, unique to us. Each neuron is connected to 10,000 others. To form a memory some 15 parts of the brain are involved. It is situated, much of it we are not aware of. Come to think of it, while I was concentrating I got cramp in my bum and right thigh perched as I am on a hard kitchen chair, and the lingering after taste of the cup of coffee I drank 45 minutes ago. I can hear the kitchen clock ticking - though most of the time it is silent (to my mind), and the dog just sighed.

Does it matter that my fingers are tapping away at a keyboard?

Though second-nature, touch-typing it still occupies my arms and hands and fingers which may otherwise be animated were I talking. I am talking, in my head. The stream of consciousness is almost audible.

What would happen where I to use a voice recorder and speak my thoughts instead?

By engaging my limbs and voice would my thinking process improve and would the creation of something to remember be all the stronger.

I'm getting pins and needles/cramp in my right leg. Aaaaaaaaaaagh! Party over.

The question posed is often 'what's going on in there?' refering to the brain. Should the question simpley be 'what's going on?'

Learning & Memory

My eyesight is shifting. In the space of six months of moved to reading glasses. Now my normal glasses are no good either for reading or distance. Contacts are no use either. As a consequence I'm getting new glasses for middle distance and driving. The solution with the contact lenses is more intriguing.

To correct for astigmatism and near or short sightedness I am going to have a one lens in one eye to deal with the astigmatism and a different lens to deal with the short sightedness in the other. My mind will take the information from both and ... eventually, create something that is sharp close up and at a distance. This has me thinking about what it is that we see, NOT a movie or video playing out on our retina, but rather an assemblage of meaning and associations formed in the brain.

I will try these lenses and hang around, wander the shops, then return. I am advised that I may feel and appear drunk. I can understand why. I could well describe being drunk as trying to navigate down a path with a microscope in one hand and a telescope in the other while looking through both. I feel nauseous just thinking about it.

So 'stuff' is going on in the brain. These days the activity resulting in the brain finguring something out can, in some instance and to some degree, be seen. Might I have an fMRI scan before the appointment with the optician? Might I then have a series of further scans to follow this 're-wiring' process.

I need to be careful here, the wrong metaphor, however much it helps with understanding may also lead to misunderstanding. Our brain is organic, there are electro-chemical processes going on, but if I am correct there is no 're-wiring' as such, the connections have largely existed since birth and are simply activated and reinforced?

Any neuroscientists out there willing to engage with a lay person?

What would observing this process of unconscious learning tells us about the process of learning? And is it that unconscious if am I am aware of the sensations that have to be overcome to set me right?

I love the beauty of  Jenga. Like Google, it's simple and it works.

Simplicity has a purity about it. Don't knock it. Behind its functionality and its look and feel there will be some hard thinking.

'Keep it simple, stupid'. (K.I.S.S) may be a training cliche but there is considerable truth in it.

I've now had three years here at the OU and here on this Student Blog platform (short of five days, first post 6th Feb 2010).

I've been working on my ideas regarding learning and e-learning design in particular Courtesy of THE OU hosted OLDs MOOC 2013 (Online Learning Design - Massive Open Online Course)

I'm experiencing what feels like undertaking an 8 week written examination - the contents of my brain are being pushed through the cookie cutter.

And out comes this:

The Good, the Bad and the Ugly

(Of course I had shut down for the gadgets for the day and was brushing my teeth when this came to me).

The Good

Learning events or activities, moments that make the participant smile, think, reflect, nod in agreement, understand, be informed and generally feel good about the world and this particular learning experience. Hit them with some of this, as the say so succinctly across the Atlantic - at the 'get go'.

The Bad

The effort required and built into the learning. OK, we want them to love this too, and you can if you're 'in the flow', have done your work, have wrestled with what you didn't understand, asked for help, listen to fellow students, gone out of your way to do extra reading and research until you have it, one way or another.

There needs to be assessment.

An assignment is a soft assessment to me - though like everyone I have terrible days when the thing just slips through my fingers like a snowball on the beach. A dissertation or end of module assignment is tougher, but tough and 'bad' in a certain way - like commitment to a triathlon. And a good analogy as working on and developing three issues at 2,000 words a pop is about right. And you won't get far if you leave training to the week before. It's a slow burn.

The 'bad' has to be the written examination.

They have to be hated and feared, and like learning lines for that school play, you have to get it right on the night (or day). And what do you do if you act? You have good lines to learn, you learn and rehearse your lines and you practice, and do a test run or two. The curtains going up is the equivalent of your turning the examination paper over. I feel the fear from a year ago - April 2012. I hadn't sat a written exam in 30 years. All my undergraduate and school-boy fears came back. I used rusty techniques that had last seen service during my first degree.

Bad is good. You want to do everything not to feel like you are naked on stage - a dream we all have when faced with such an 'exposing' test?

The Ugly

Shock 'em. Not scare the witless. Have up your sleeve some smart stuff. Whether an idea or the technology offer a creepy and certainly memorable surprise.

Boring a student into making a fact or issue stick is like throwing mud at a brick wall - it'll stick, it'll coagulate and build up, but is easily washed away in a shower and destroyed in a storm.

Use storytelling techniques perhaps, better still, follow the pattern of a ghost story.

Scare them? I'm back on fear I guess.

We humans are fearful of many things and will go out of our way to avoid, run away or confront our fears. As I said, the idea here isn't to lose your students, but to empathise with them, understand the ugly side of their learning experience then help them confront their worst fears. It is ugly having to tackle the parts of a subject that stink, but inevitably these are the blocks at the base of JENGA.

So can I apply it? And can I go back to bed now?

Which leads me to another theme - we no longer simply bring work home with us, we take it to bed and sleep with it. If this pisses you off then let me introduce you to 'working with dreams'. If you are prepared to get up for an hour in the dead of night, or can flick on a light without invoking divorce then scribble stuff down to catalyse the thought in the morning. Can work wonders, can produce nonsense, can just be some things you need to put on the supermarket shopping list ... or another dream of being naked on the stage, not knowing your lines and needing the lo but all the exits are locked and the orchestra has stopped and you have to say something.

Which, courtesy of the wonders of the mind, has me in the front row of a performance of The Tempest at the University Theatre, Newcastle when I was 13 or 14. Caliban was naked, covered in mud and wearing a prosthetic erect penis.

HORROR!

P.S. And give me 20 minutes searching the Internet and I will be able to name the actor, date the show and possibly even find a picture. Perhaps you'd like to have a go. But before you do so, be very fearful of what the search terms you use might throw up.

P.P.S. It may have been David Suchet, with Juliet Stevenson or some such as Aerial. The performance was in 1974, possibly a precursor to the RSC doing a Newcastle Tour every March at the Theatre Royal and Gulbenkien. It may have been Jim Carter. Or none of these!

Fig. 1. End of Year 2012 Ante-smoking TV commercial and campaign

If you find the current anti-smoking ads powerful, in which a cigarette grows a life-like tumour as it is smoked, then imagine what the word 'disembowel' conjures up?

I do not suggest that you Google the word as I did wanting to correct my spelling 'disembowl' - which, if correctly defined might mean nothing more challenging that taking a bowl out of a cupboard, or away from a child who is playing with their breakfast.

I deliberately offer neither a link, nor an image.

It shocked me that even I could so naively stumble upon a gallery of such horrific proportions that includes CCTV footage of road accidents and the aftermath of murders, killings and war zone collateral damage. I am now forever damaged. My mind will run amok with these images forever - to scrub them would require cognitive behaviour therapy and hypnosis.

If I ever need to put my teenage children off the idea of riding on a motorbike, or getting a motorbike of their own I know what Google search will will put them off, potentially keep them off a pedal bike too. I've now seen what happens when a truck hits a stationary motorbike that is waiting to take, in this instance, a left turn off the main road.

I believe in the power of images - for advertising and for learning purposes.

I believe that the more genuine the image, however contrived and constructed, in its appropriate context - the more memorable the facts, events and circumstances are as a force to inform or educate. I believe also that where this image is animated, live or as live video, with both visual and auditory clues, the more powerful it becomes.

The police don't show reconstructions of traffic accidents to drunk or reckless drivers - they show them the real thing.
