Margaret’s Journey – BE CURIOUS!

Monday, April 12th, 2010

Among the experts, there is a clear consensus that the potential increase in numbers of people suffering from dementia in Australia is something to worry about.



DEMENTIA – THE MAJOR DISEASE OF THIS CENTURY



• New report predicts over 1.1 million Australians with dementia by 2050
• By 2020 there will be 75,000 baby boomers with dementia
• Dementia is on track to become the largest source of health and aged
care spending.



This is not a controversial matter.



Is it inevitable? Is it preventable? Can dementia be delayed?

Which approach to take in terms of the current aging population is controversial, however… even if you accept the science, then what to do about it is a very difficult political issue. It’s an issue where the risks and benefits are very long term. And in politics, the urgent always trumps the important.

Take precautionary action

Age changes can be serious and the risk associated with them can be substantial. Precautionary action is called for.

Choosing to maintain a healthy lifestyle is fully justified as an insurance policy against the worst case scenario and action should be based on that worst case scenario; the high risk end of the probability of dementia for an increasingly aging population. In the end it’s a cost benefit analysis and really a concern to try to avoid the worst case if possible.

In my view there is no doubt whatsoever that everyone should be making an effort now (at 30, 40 50 or 60 and onwards ) to reduce their chances of the adverse effects of aging. The younger the better. The scientific evidence shows that aged brains can carry the evidence of dementia, but there is sufficient ‘cognitive reserve’ to have prevented manifestation of the disease.

To be on the positive side, all the things we ought to be doing, and enjoy doing and which we could benefit from, are things that will be a step towards the target of reducing the occurrence of dementia. But even without that motive, they are things we should be doing anyway. Unfortunately, as Michael Merzenich says, “many older people simply want an easy life..”

In the brain it is the challenge to the nerve cells and their plasticity that is important. One way to be certain of continued enrichment is to stimulate and maintain curiosity throughout a lifetime.

Margaret’s Journey #41 – Pilot Training

Thursday, April 8th, 2010

My son is a pilot, consequentially I am very interested in his regular check and training sessions. By law, throughout their career, pilots in all airlines have to undergo pretty rigorous real-time training runs, check flights etc. When my son goes to Melbourne to perform on the “SIM” (that is short for “simulator”), he sits in the simulated cockpit of an aeroplane and his supervisor “throws everything at him”!!!! This is “pilotese” for engines failing or on fire, instruments crashing, weather etc.

The reason for the simulation training is to expand on the real-world aircraft training, teach cockpit resource management and simulate emergencies that are impossible to safely duplicate in the air. Not only does he speed up his responses which are critical for real-time decision-making, high-demand tasks, he also learns to keep his emotions in check (the dead calm of pilots). He also has regular medical check-ups. What else would we, as passengers expect of our pilots? They must be ready and cognitively capable of dealing with all possible emergencies.

A Parallel?

Can you see the parallel I am suggesting? By working on your own brain fitness and thinking about what pilots have to do

  • about keeping in training, life-long learning
  • about managing resources,
  • about a healthy brain.
  • about optimising your performance ,

your situation can be no different in principle from the everyday expectations we have of our pilots.

Simulation on your computer

By working on your computer on brain fitness you are increasing brain plasticity and other resources like increased attention and an expanding “useful field of view” (UFOV). That should stand you in good stead in real time when you are driving. Although we can’t exactly simulate emergencies in the real-world there is clear evidence that training with computer simulation can transfer to aspects of real world experience.

By working on scientifically validated computerised brain fitness exercises and looking after your health and fitness, you are managing your resources in order to keep sharp (at whatever age), to be active and at the best you can be-in-the-real-world now and for the future….just like our pilots.

“What research has shown over the last 15-20 years is that cognition, or what we call thinking and performance, is really a set of skills that we can train systematically. And that computer-based cognitive trainers or “cognitive simulations” are the most effective and efficient way to do so.”
Professor Daniel Gopher, Professor of Cognitive Psychology and Human Factors Engineering, Israel’s Institute of Science.

Margaret’s Journey #40 – More Pasta Sauce in My UFOV!

Monday, April 5th, 2010

UFOV assessment. Click to enlarge

I more than met my UFOV training goal this time! The Road Tour assessment showed a 70% improvement over my starting level.

Yippee! I can see a wider circle when looking at a supermarket shelf now, apparently. But what’s the point in a supermarket? It will give me 15 choices of pasta sauce or baked beans in a row to choose from as opposed to 10 previously! Think of all the extra small print to be read to see if it is Australian made, imported or contains flavourings…..

Can you decide which to buy from the multibrands?

To solve this new dilemma try “How We Decide” by Jonah Lehrer, a great read. He had a problem choosing cereals and wrote this book.

“Explaining decision-making on the scale of neurons makes for a challenging task, but Lehrer handles it with confidence and grace. As an introduction to the cognitive struggle between the brain’s “executive” rational centers and its more intuitive regions, “How We Decide” succeeds with great panache.

Margaret’s Journey #39 – Master Gardener Assessment Advice

Thursday, April 1st, 2010

Well! This was a surprise!

My first activity for the day’s training on Insight was programmed in as an assessment on Master Gardener (visual memory). I took the assessment and failed miserably- achieving only 9% improvement on the baseline and not reaching the set goal…..

So I sighed deeply (it was memory again….)….

I continued with the remainder of my training session and gradually warmed up as I did Road Tour, Jewel Diver and the Sweeps.

After my 40 minutes training, I thought I should try my assessment again and see what happened. (If at first you don’t succeed try, try again!)

My improvement went from 9% to 62% in 40 minutes!! (see chart) I surpassed my goal by miles! How is this possible? Perhaps I actually have acquired these long plastic brain extensions I was asking for from the UFOV (unidentified flying object V)…click my earlier post here.

SO IF YOU WANT A GOOD ASSESSMENT DON’T DO IT AS YOUR FIRST ACTIVITY! GET SOME PRACTICE IN AND THEN DO IT…

Anyone else had such varied assessments? Or even an assessment you want to share?

Margaret’s Journey #38 – Jewel Diver: First Assessment

Monday, March 29th, 2010

Jewel Diver results

I improved by 18% on this exercise. I knew my performance was very varied. Some days I could handle 6 hidden jewels in correct order, other times I went right back to 2!! As well as tracking in memory in increased field of view you are working on maximising points by remembering to collect a 2 or 3 jewel group of the same colour etc. Working memory is my nemesis….

  • The Goal

My goal was 4.69 items- a 15% improvement. This is equivalent to tracking 4.7 people in a crowded place.

  • My achievement and new goal

    My assessments so far

My achievement was 4.83 items, meaning I had surpassed my goal! My new goal In Jewel diver is 5.2 items, an improvement of 28% over my starting level.

Margaret’s Journey # 37 – Bird Safari

Thursday, March 25th, 2010

I’ve had my first assessment on Bird Safari! I have been following the provided order of exercises, so the assessment was delivered to me at the appropriate time.

I felt sometimes that I was never going to be able to detect the target bird. But the program design is pretty nifty:

  • Training visual acuity: the birds were remarkably alike.
  • Training Divided Attention and UFOV: the distance between the focal centre and the birds lengthened
  • Training figure/ground discrimination: a bird had to be picked out from backgrounds that became more complex
  • Training complex visual discrimination: The number of birds (distractors) increased
  • Training speed recognition

However, my Personal-Trainer-at-my-Elbow (calibration) slowed the speed of presentation considerably while I caught up (see above picture).

Northern Harrier

Sometimes I surprised myself by “knowing”…..the amazing brain again! When you get to complex backgrounds to make discrimination harder, I found that that when the Northern Harrier was silhouetted against a white sky, (which was not complex at all) I couldn’t detect the elusive creature ( that is not what I called it in the heat of the moment!). I think the light background made it look much darker. Nice birds though!

What kind of experience are you having with the Bird Safari exercise?

My assessment results

I improved by 54%. (see chart) this is interpreted to mean that I can stop a car 26.8 ft earlier than when I started the Insight program. My new goals have been set for me. (click to enlarge picture)

Margaret’s Journey #36 – Jewel Diver: Dividing Your Attention

Monday, March 22nd, 2010

Current level: track the movement of 6 jewels

Keep track of the 6 jewels hidden in a moving group of twelve

It is fascinating to experience divided attention in this game format from the Insight program……

I find it is not possible to focus directly on one or two bubbles as they swirl around with the jewels behind them while hoping to keep track of the other four. My narrow attention spotlight simply doesn’t work!

I find I am watching something that doesn’t quite exist..

Dividing your attention is like taking a step back so that you can survey the whole and be aware of particular elements in the display that are important.

Dividing my attention so that I remember where the jewels are, is almost like daydreaming: I seem to be watching something that doesn’t quite exist….tracking a jewel group even although they are separate bubbles. The relevant ones with the jewels behind them seem to stay linked together and the “discards” fade into the background.

The exercise is taken to a higher level by increasing the area, the number of jewels and the movement. Your peripheral vision is given a real workout, but my feeling is that it is much more “whole brain” than that implies…. anybody got any ideas about this?

The real-life connection is to enable keeping track of people in a busy place, or an area like a park.

Increasing space

The targeted bubbles seem linked

Margaret’s Journey #35 – Master Gardener

Thursday, March 18th, 2010

Working memory is my really weak point (as shown on the Brain Fitness Program) and my heart sank when the next session indicated that I was to be working on it again!.

The dreaded working memory again!

In this Insight exercise we have the same principles at work as the BFP: but this time training visual working memory (of less than a minute) with a gradual increase in task difficulty. The number and distance between items to be recognised and/or matched in peripheral vision is increased as you progress.

After a tutorial, the Master Gardener assessment took 10 minutes to establish my visual working memory starting level.

Baseline: 545ms.

Goal: 360ms

I really like what Posit Science says in Page 2 of the Overview which comes with the disk.

“Our approach is more like the one a good gardener takes: we don’t just tend the flowers and leaves (memory tasks). We understand that no matter how much you care for the flowers and leaves, the plants won’t be healthy unless its roots (sensory perception) are also in good shape. The roots must be able to take in and deliver crucial nutrients (information) to the rest of the plant for it to thrive.”

How true that is for plants, trees and even large stable eco-systems! Posit Science claims that “Insight exercises a key set of these roots”.

A paced approach to training on Insight:


Look at the advice bubble! It deals with tension….

Take your time....

Pause, review, get help, look at the flowers, exit or take a break!

Even the “THUNK” sound when you get it wrong is more gentle than in the Brain Fitness Program. That sounded like a hammer in a metal bucket …..I found it quite punishing! In fact towards the end of the Brain Fitness Program I ended up with a tea-towel over the top edge of my computer screen to avoid seeing the red arrows and red squares reflecting my inevitable working memory failures as I worked towards the final session.

But I was determined to finish. Malcolm Fraser’s well-worn phrase sums it up , “Life wasn’t meant to be easy!” This has generally been taken as a gloomy explanation of life’s difficulties, but for him rather it was a reason to take on difficult tasks. I quite like that.

Margaret’s Journey #33 – InSight and the BFP

Thursday, March 11th, 2010

The Attention Buttons on Insight and BFP

Visual and auditory processing
Both programs are concerned with sensory input, one auditory (the BFP) and one visual (Insight)

  • GET READY! Start buttons demand our attention in both programs.

Auditory Sweeps Identification

Horizantal bars of varying widths and intervals move in and out.

In the Brain Fitness Program, auditory sweeps UP or DOWN of varying frequencies and interval are presented through your earphones. You are required to select the correct order using the arrows.

In Insight, visual sweeps, horizontal or vertical bars of varying widths (frequencies) move IN or OUT , and are presented in a game context. You are required to select the correct order from the buttons “IN or OUT” with rewards attached.

Visual sweeps IN or OUT are indentified in a game format

  • speed of processing

The sweeps in both programs measure speed of processing in the auditory or visual sensory systems.

  • baseline assessments

You also are given a baseline assessment and tutorials in each sub-program, however there is choice built into Insight but not in the BFP.

  • getting it right

The same old personal trainer is sitting at your elbow, making sure you are getting it right ( see my post on errorless learning)!

  • rewards

You can skip rewards in the BFP , but in Insight you get them awarded regardless. Actually they are graphically quite delightful and contribute to the enjoyment of the exercises.

Bird Safari has some of the features of “Match-it” in the BFP, with the identification of the target bird and its position in space becoming increasingly difficult. I imagine that as the birds get more visually similar and demand greater acuity it will be of the same genre as “Tell us Apart” in the BFP. In that exercise using computer generated syllables, it became more and more difficult to discriminate between them.

“Master Gardener” is concerned with visual memory, rather like

“Sound Sequencing” in the BFP where auditory sequential memory was tested. In Master Gardener the correct identification is required but the sequence is immaterial and makes it easier (I think!). Some visual acuity is certainly required and UFOV is involved.

The rules of the game

I was glad to feel the similarity between the two programs in terms of structure, assessment, goals, timing and calibration. I feel I know the rules of the game! They are very different experiences, however. Methinks there has been some neuro-plasticity occurring in Posit Science?

Anyone done (or doing) both programs and see any similarities (or differences)? Any preferences?
