INSTRUCTIONS color monitor and a watch [ideally a stop watch] required for demonstration

TASK 1

  1. You will need a watch to record how long it takes you to finish this task. 

  2. Record the time to the nearest second.
  3. Just read each word aloud as you normally would when reading. Start at the top, go left to right, line by line, as quickly as you can and correct any mistakes. For example, the first word is "green", the second is "brown" and so on. Remember to record how many seconds you take to finish. 


TASK 2 

  1. Again, use your watch to record how long you take to finish this task.

  2. This time, instead of reading the word, you have to name the colour of the ink in which each word is written, going left to right, line by line, as quickly as you can and correct any mistakes. Speak up and say it aloud for greater effect. For example, the colour of the first word is "pink" so you have to say "pink" instead of "green". The second is "red", not "brown" and so on. Do the whole list from top to bottom. Don't forget to record how many seconds it takes you to finish. 
Read on for an interpretation of your scores and a new theory and explanation of why old habits die hard.

Interpretation of your scores 

  The first task is quite simple. Everyone is good at reading words and most people take around 30  seconds to finish this task. Reading words is a well established skill that requires little if any  conscious effort on our part. We have practised reading for a long time and have become quite good  at it. It happens almost automatically and effortlessly, without having to exert our powers of  concentration. You make few if any mistakes and there is no mental conflict involved.

  The second task is very different. People say they have to consciously suppress the tendency to want  to read the word, to revert back to their old habit (Task 1). The old habit ("green") tries to interfere with  the new learning ("pink"). But today the old habit is "wrong" - "green" is wrong and "pink" is right.
Times are very changeable, as we all know. You now have to quickly change your knowledge, your  skills and that is very difficult.

  Old habits die hard, as we all know. The interference effect slows down our learning of the new  information, the new skill. Because we all differ in how much interference we experience on this task,  the time it takes can vary from 40 seconds to 150 seconds or more. Clearly, people differ in the  strength of interference from prior knowledge but everyone takes longer on this task than the first task  and some people take very much longer. Most people take from 2 to 3 times longer. The important  point is that we all have this problem and this is why we all dislike and resist change. It is the reason  why old habits die hard.

 Apart from taking longer to complete, the second task also generates mental conflict and emotions in
 people. Over many years of doing this demonstration with all kinds of people and occupations, we
 get comments like these, "It's really hard", "I really had to concentrate hard", "Noisy people around me
 made it even harder to concentrate - I tried to screen them out but there was more interference", "I got
 really frustrated by not being able to do what appeared to be a simple and easy task", "I had to
 actively stop myself from saying "green" when I knew I should be saying, "pink", "I got angry and
 frustrated at my inability to change quickly to the right answer".

 This emotional reaction is the same reaction we experience whenever we try to change what we
 already know and what we can do. It is a universal response to change in human beings. It helps to
 explain why people resist change and why old habits die hard.

 While you are welcome to try this test on your family and friends, please resist the temptation to
 compare your scores with those of others. All that really matters is how your score on the second
 task compares with your score on the first task - the greater the difference, the more likely you are to
 experience interference from your prior learning and the longer it takes you to change and adapt to
 new things and ideas.

 In case you were wondering, performance on this demonstration seems to have nothing to do with
 intelligence as measured by IQ tests. The interference effect seems to be independent of other
 abilities although if you have a big difference between task 1 and 2 it is possible that you have a more
 retentive memory. It also means that you may find it harder to change your established ways.

 In your brain you have an inbuilt, hard-wired mechanism that protects and preserves everything you
 know - all your knowledge, skills, beliefs, understandings, and so on. Once you have practised, i.e,
 repeated, and learned something, it starts to becomes instinctive and automatic for you. At that point
 you can perform the skill effortlessly, without having to concentrate on each step. Your brain
 mechanism protects and preserves what you have just learned and this saves you having to re-learn
 it all over again the next time. In this way, the brain mechanism is a real bonus.

 But when time comes to change what you know, this same mechanism still tries to preserve all your
 prior knowledge. It does not matter whether what you know is "right" or "wrong" for you; everything is
 preserved. Even when you have no further use for this knowledge and you really need and want to
 change, that knowledge is still protected from all attempts to change it. To your dismay, you then
 discover what it means when we say that "old habits die hard."

 All this happens unconsciously, behind the scenes, inside your head and unintentionally. And you
 have no control over it. The knowledge protection mechanism is activated automatically, instantly,
 and fully, whenever what you are trying to learn differs from and conflicts with what you already know.
 You want to change but your brain won't let you change quickly. The conflict between the new
 knowledge or skill, and your old established knowledge or skill, generates massive interference with
 learning. This is known in the psychological research as proactive habit interference or proactive
 inhibition. This interference affects your ability to recall the new knowledge or skill you just tried to
 learn. Within minutes or hours, you forget what you have just learned and fall back to old ways. This
 is called accelerated forgetting. Together, proactive inhibition and accelerated forgetting explain why
 old habits die hard, and why change is so slow, frustrating and expensive.

 Proactive interference, i.e., when old learning interferes with new learning, accelerated forgetting, and
 the associated reversion to old ways are familiar to us all. If you have ever tried to change your golf
 swing you know how hard that is. You have to concentrate hard on every step. The new way feels
 strange, having done it the other way for so long. You get confused, frustrated, performance slows
 dramatically, and your error rate goes up. You appear to forget what you've learned from the coach
 and fall back to those old, wrong, ways. You can do it correctly during coaching sessions and appear
 to improve. But, as soon as you are left to your own devices or have to perform under the stress of
 competition, your game falls apart and you revert to those old, wrong, ways. This roller coaster ride
 may continue for weeks, months, or even years. It is called the "adaptation period" and is well
 documented.

 In our new theory of human learning, the adaptation period is seen as symptomatic of mental
 interference with learning. It is a sign that the brain is experiencing conflict between the old and the
 new learning. Proactive inhibition and accelerated forgetting are the result - that is what produces the
 adaptation period and slows down change and improvement.

 It follows that the adaptation period is an indicator of a brain in trouble. The person is no longer
 learning efficiently and effectively but is struggling to cope with change. Currently available teaching,
 training and learning methods, and change methodologies, result in a prolonged and resource
 expensive adaptation period. This suggests that most coaching, teaching, training, therapeutic and
 other behaviour change and concept change methodologies are working against the brain; not with
 the brain. These approaches inadvertently activate the brain's knowledge protection mechanism and
 make it harder for the person to adapt to new ideas, new skills, new techniques, and new
 procedures. Clearly, we need a better way.

 Old way/new way overcomes the brain's knowledge protection and maintenance system, greatly
 reduces the interference from prior conflicting learning. It empowers individuals to adapt more quickly
 to change, improve and become more flexible. It virtually eliminates the typically prolonged period of
 adaptation to change that accompanies more conventional teaching, coaching, training, therapeutic
 and other behaviour change methods, making it possible for individuals, groups, teams and
 enterprises to truly achieve continuous improvement and more cost-effective change management

NEO - New English Orthography

Scientifically controlled experiments suggest that digraphs or, more broadly, multigraphs, make a language significantly more difficult to read.

For dyslexics, it makes a language that is otherwise consistent, as difficult as English to read. If true, this has obvious implications for Truspel. An orthography with a 1:1 grapheme/phoneme correspondence would be more advantageous to approximately 15-20% of the population, those with dyslexia and
other LDs that impede learning to read. This is important because they would be the first eager consumers of a new orthography. In addition, there is evidence that a 1:1 orthography would increase average reading speed by 10% for ALL readers.

                 I think that Paulesu's findings in regard to the dyslexics' problems reading
                 English and French should be applied to an evaluation of Truspel. His findings
                 showed that the number of dyslexics in the US having reading difficulties is
                 double that of Italy because of orthography. Since about 15-20% of all people
                 have dyslexic or dyslexic-like reading disabilities, I think their needs
                 should be considered in a any choice for a new orthography. These decisions,
                 however, would not only affect them, as I want to show below.

                 There is no question that Truspel is easier to read because it is a shallow
                 orthography. I have questioned, however, the inclusion of digraphs. My argument
                 has been that it takes at least double the processing time. (Actually, since I
                 have said that, I have reason to belielvle it is much more.) In my opinion it
                 seems to me that Paulesu’s latest experiment (March issue of Science) includes 
                 a very strong argument against using digraphs. Why?

                 He found that French was nearly as difficult as English for dyslexics, yet
                 English is far more inconsistent with its phoneme/grapheme correspondence. As
                 Steve has pointed out, French often has more than one grapheme for one phoneme,
                 but there is no code overlap. Once the code is learned, it is far easier than
                 English to read for adults like us. Why, then, do dyslexics have so much more
                 difficulty than we do?

                 Could it be this: there are so many multigraphics (eau, ots, ou, er). Even
                 though they are phonemically consistent - no code overlap - there are many such
                 multigraphs. I don’t have any French in front of me, but I wouldn’t be a bit
                 surprised if at least 50% of the words have these silent endings that can be as
                 many as 3 (or 4?) letters.

                 I myself can see no other reason why French and English would be so close in
                 difficulty for dyslexics since that that seems to be the only factor that makes
                 French difficult, its multigraphic nature. If anyone else can see any, please
                 let me know.

                 Although I know of no tests for French, Uta Frith and Wimmer have experimented
                 with comparing word recognition times in English and German. English is about
                 7% slower. Considering the Frith/Wimmer experiments, French is probably equally
                 slower. This difference in what they call “latency time” should translate into
                 reading speed. I asked Paulesu this, and he agreed.

                 If all of this is true, it means that a one phoneme/one grapheme principle will
                 be beneficial to all.

                 There is another important advantage: my calculations indicate that a 1:1
                 system would consume 15% less space. That means that each line of type can
                 contain more words. This saves eye returns to the next line - dead time in
                 terms of reading, and, after a while, some fatigue time for the extra
                 concentration to return to exactly the place on the next line. I would guess
                 that the loss would be perhaps 2 words per minute per line. If that were
                 calculated on the basis of a 10 word long line for TEO, the savings is 3.5%.
                 Combine that with
                 the 7% faster recognition time, and the total is 10% faster reading time.

                 I have put together in about 2 hours a few sentences in a 1:1 principle. I used
                 graphemes in the upper ASCII that serve quite nicely because all of them are
                 reminiscent of TEO graphemes. I have tested it with 3 people, and all were able
                 to read them without any key. I had them compare it to the same sentences in
                 Truspel. They found the digraphs in Truspel also readable without a key, but
                 somewhat disconcerting. I also had one dyslexic (she is a dyslexic teacher of
                 dyslexics) read both, and she had the same reaction. These results
                 conform with what the Paulesu et al experiment predicts.

                 The advantage of being so easily backwards compatible to TEO, of course, is
                 that acceptance would be faster. That is, people would be more willing to
                 experiment if they knew that the transfer to TEO, should they desire, would be
                 fairly smooth. Dowling’s studies show a remarkably quick transfer. He doesn’t
                 mention problems, but if there were any, they have to be measured against the
                 problems with an exclusively TEO approach.

                 If all of this is correct, the advantage to a 1:1 system is considerable. The
                 objection cited by many is the keyboard changes. I have written a detailed post
                 that nobody has yet responded to that shows that a normal keyboard could be
                 used for this provided capital letters were eliminated and the numbers keys
                 (plus -, =, `) occupied. Numbers could be typed from the numbers pad. Since
                 very few touch type numbers, there is no great loss (I would lose because I
                 touch type numbers). In addition, the keys with [, ], \, x and q would make
                 up the final deficit for a total of 44.

                 An alternative to using the number keys is the PF keys. Those could eventually
                 be moved down by manufacturers so they could easily be touch typed when there
                 is enough quantity us to justify it.

                 You have pointed out that one impediments to reform has been the lack of
                 computers that can translate texts into NEO and that computers can now easily
                 rectify this problem. The introduction of the small and portable SI will be a
                 further step that allows any text anywhere to be instantly interpreted into NEO
                 -- or vice versa. Also, Valerie tells me that 1:1 orthographies in the past
                 have not been accepted because they could not easily be sent around. The
                 internet and computers obviates that problem.
