Therauputic uses for toki pona, draft for comment

Post by janMato »

Prophilaxis and Rehabilitation of Post Stroke language problems
If toki pona is somewhat like computer programming code and algebra, and if a stroke spares the ones ability to write code, and if the effects of the stroke are largely limited to abilities of speech, then toki pona might be useful as a way to express thoughts without relying on the parts of our brains that normally process language and instead rely more on the part of our brains that process math.

For much the same reasons, toki pona may be useful in dementia or brain cancer. In dementia and brain cancer, skills are lost at an uneven rate. Mutlilinguals lose all their skills last. Knowledge of any second language is an insurance policy against this eventuality, toki pona is an inexpensive "policy" in terms of hours it takes to learn.

At the moment, it would be more prudent to learn toki pona long before a stroke. After a stroke, one will probably still want to make an effort to rehabilitate their ability to speak English and it isn't immediately obvious that the effort to regain English is greater than the effort to learn an artificial language.

25%-40% of stroke survivors have aphasia, 100,000 people get aphasia a year in the uS and 1 million have aphasia now.

Communication for disabled children who can not speak or sign.
English is ill suited for pointing based language, i.e. language where you can only communicate via pointing. The alphabet is small, but pointing to all the letters for a sentence is excruciatingly slow.

Bliss symbols in one of the more famous systems created for this purpose, but there are many other competing systems. Toki pona has the advantage of only requiring a ~125 word symbols, 35 syllables and 14 letters or 174 symbols total. If the toki pona community continues to innovate scripts and short hand techniques, toki pona could potentially become more efficient than pointing to the English alphabet. As an added plus, this proposition is eminently testable by determining if equivalent phrases in English and toki pona require more keystrokes.

Another advantage toki pona has over some systems is that the language is rigidly isolating. Symbols do no inflect based on changes internal to symbols-- a technique common in Blisssymbols that some children and adults found difficult.

Adult onset dealfness.
English is ill suited for signing-- it has a heck of a lot of words that need to be signed distinctively. ASL is perfectly fine if you know it, but is a natural language, so it poses the same challenges of French or Spanish in that it takes 500+ hours to learn. Signing each letter is slow and tedious as is writing everything down. A lanugage of a small number of isolated morphemes would be easier to learn for a deaf adult and the hearing community around them. Or they can learn ASL or signed English.

Depression.
Depression is usually treated with a talk therapy or anitdepressants. The antidepressants either work by modifying brain chemistry or they work via the placebo effect.

It's also been speculated that antidepressants work via a neurotropic effect. In that case toki pona could be effective as a way to encourage neuron growth.

The other possibility is that a language that makes it difficult to think unhappy thoughts and easier to think happy thoughts would help the symptoms of depression. This pivots on the various forms of the Saphir-Worf hypothesis, which is considered difficult or impossible to test and certainly the linguistic community is no where near the level of consensus comparable to the level of consensus one sees in the medical community when asked about the relative efficacy of leeches, tin hats or pennicillin.

If anti-depressants work primarily through a placebo effect, then toki pona is an excellent palcebo because conclusive evidence of it's efficacy or lack there of doesn't exist--yet. So anyone using toki pona will get most of the benefit of the placebo effect, if indeed that is the main mechanism. Furthermore, linguists won't stop aruguing about Saphir-Worf effects for years.

Preventive Care
There are a few charactistics of languages that make them more suitable for prophylaxis than for care after a health event.

Languages need to exist in a community for them to be useful. If a language user doesn't have at least one domain in which to use a language, it won't be used. An unused langauge can't possibly have a therapeutic effect any better than sitting through a Spanish class or underwater basket weaving class, for that matter. That domain of use and the community of friends who use the language need to be established in advance of a health event for a constructed language to be pragmatic.

It takes 500 hours to learn a language, possibly fewer for toki pona. In the case of stroke, brain cancer--there might not be the time or mental resources for taking the time to learn a foreign language. Moreover, the surrounding community would also need to get up to speed on the language.

Why an artificial language and why this one
For some of the purported effects listed, one could just as easily study Spanish or Chinese. Toki pona has the advantage of requiring fewer hours to master. Esperanto (and maybe even Piraha), Basic English also make claims of being unusually "easy" languages. The disadvantage of Piraha is that materials for learning Piraha are extremely rare and aimed at professional linguists.

The state of the art in the design of easy to learn languages has been making progress over the last few hundred years, so there is likely a trade off between ease of use and the size of established community.

As noted before, languages don't exist without a community. Every community is different and the community one finds themselves in will in large part determine what language can be spoken, regardless to their merits.

Is it? I suppose Lojban is more like that, but even it seems to be just a human language. This is true that in many constructed languages the syntax gives less ambiguous results than in natural languages. In Lojban, based on predicate logic, relations between objects can be expressed very precisely. But programming languages have precise language rules ("grammar") and precisely defined data structures ("words") they work on. Even if we have a good parsing machine, the more the meaning of processed symbols is fuzzy, then more the meaning of a result is imprecise, contrary to these from algebra or computer code.

Moreover, toki pona is especially difficult for this kind of automatic parsing, because almost each word can have several grammatical interpretations and relations between them rely heavily on the context.

Interesting. Are they?
Far for knowing neuroscience or linguistics I found only the following:
Is math lateralised on the same side as language? Right hemisphere aphasia and mathematical abilities. Semenza et al. (2006)
and 'Expressive Aphasia' blog with this article: I don't know my ABC's what about Math?

Dunno about Lojban, but a few days ago I got the idea of using toki pona as an information representation format, similar to RDF or XML or relational tables. I haven't finished baking the idea, but it looks like a lexer and parser similar to the kinds used to parse programming languages could be used to parse toki pona sentences.

The only thing precise about computer programs is that it is a precise representation of how memory and I/O will be arithmetically manipulated and shuffled about. Having worked for a long time in software development, the code and the relationship between specifications and how the business that uses the application (or the mental models of the users) has a pretty weak relationship. One program represents thousands of possible configurations of the real world. One program represents thousands of possible configurations of understanding of the users. In the shuffling of bits and bytes, programming is physics. In the relationship between the computer and the social world that interacts with it, it's all interpretive dance and handwaving. (Exceptions would be programs that are dealing with essentially non-human problems, like calculating pi to a billion places)

Exactly. Toki pona is a programming language like XML. Simple, precise syntax, yet vague and fuzzy semantics.

Not an unknown situation in the programming world. Open the source of this forum and you'll see HTML (the grandfather of XML), and the intepretation of the tags depends on context. Sometimes a p tag means paragraph, sometimes it means "put white space here".

Dunno, hence me prefixing everything with "if". Wikipedia says that lateralization and specialization of parts of the brain is over sold in the popular media. I know I've read somewhere that even in patients with aphasia due to brain damage on the left side, they get predictable language loss, but it's unpredictable how much because some language processing is done elsewhere. It is known that skills disappear in peculiar fashion, one skill disappearing while sparing another.

Wikipedia's article on acalculia seems to focus on +,-,/, and * (and the two that you pointed me to). When I write code all day, I don't feel like I'm an accountant adding columns of numbers. So I'd say we're not sure where or how much localization there is in the brain regarding the skills required to create essentially a fancified XML document - i.e. the sort of talent it takes to write certain kinds of toki pona utterances.

Interesting articles! It especially interesting that the article speculated that anything that requires recursion might be left brain centered. If jan Kipo is right (that recursion is largely unnecessary in tp), then my hypothesis might still be viable.

Anyhow, I'm going to wait for some left hemisphere brain damage to happen and report back my results. In toki pona of course.

You have written about computer programming code and algebra, so I thought you mean the code written in some programming language -- the source code (or the algorithm?). Not about machines and their limitations nor about interpretations of the results. Just pure abstract "non-human"(?) processing, like, say, "X is an integer variable with initial value of 0. Increment it by 1 until it reach 10". In programming and algebra the objects are pretty well defined, in toki pona are not.

The HTML "p" tag means "paragraph" (semantics!) and this is the only meaning of this tag. In "the programming world" it does not mean "put some vertical white space between these two chunks of text". The W3C says
There is not single word about visual representation, the rendering of this tag. Practice of using "p" tag for non-semantics purposes is against the rules, so you cannot use the argument. Unless you accept using some tp expressions against tp rules.

Back to comparison. In toki pona a word can have several grammatical interpretations, but in a programming language a keyword, say, 'for' doesn't mean: "'for' or 'if' or 'break' or 'variable-name', depending on context". Even in XML, this:
  <book>a magic show for Tom's birthday</book>
and this
  book a magic show for Tom's birthday.
have different meaning.

Is toki pona ambigous? Yes.
Are computer programs ambiguous? Yes in several ways and no in 1. The specs are ambiguous with respect to their implementations and the implementations are ambiguous with respect to their
Is the syntax of computer code ambiguous? Sometimes-- for example, the source code of programming languages with out line terminantors often can be parsed several ways. Similarly, malformed html (which is the vast majority of html) is ambiguous. Also, the possibility of compiler optimizations means to me that there is some ambiguity the compiler can exploit to improve performance without changing the output too much.

Anyhow, this ambiguity line of thought, I've lost how it relates to my thesis. I said that toki pona and things like XML and code are similar. They both have a BNF form. The production of both can either be done linguistically or like an algebraic proof. When solving a quadratic equation, I'm doing truth preserving transformations until I have X isolated on one side. When I write code, I do transformations that preserve the code's compile-ability. When writing toki pona one can either just speak without thinking too hard about it (rely on one's built in machinery for language production) or one can follow the BNF spec and do validity preserving transformation.

re: HTML has a spec that people don't follow
Yes.

Actually I can think of a programming language that does let otherwise identical looking tokens vary by context, SQL. You can give column names the same names as keywords. It's an uncommon feature to let users use keywords as variable names because it makes life hell for the compiler writers. When a compiler comes across this ambiguity it has to resolve it to the most likely appropriate meaning, the same as people do.

Anyhow, a lot of these objections have to do with how people read toki pona (or how a compiler reads source code or how a CPU reads compiled code), and I'm talking about how toki pona is produced-- it's produced by humans and it is nearly such a limited subset of natural language that one can produce sentences with the same skill (and potentially part of the brain) that it takes to create valid algebraic statements, or valid SQL or XML code.

(Well, I guess people with brain damage will still need to understand toki pona, so in a sense a toki pona listener has the same problems of a compiler writer, they need to take code and convert it into several possible configurations of thought and then pick amongst them which one is best.)

Anyhow, like I said, it's a testable proposition. All I need do is sit and wait until I suffer from localized brain damage and see if the skills of programming, algebra, natural language use and toki pona use all disappear at the same time.

article,Bilingualism as a protection against the onset of symptoms of dementia
_____________________________
Abstract: This study examined the effect of lifelong bilingualism on maintaining cognitive functioning and delaying the onset of symptoms of dementia in old age. The sample was selected from the records of 228 patients referred to a Memory Clinic with cognitive complaints. The final sample consisted of 184 patients diagnosed with dementia, 51% of whom were bilingual. The bilinguals showed symptoms of dementia 4 years later than monolinguals, all other measures being equivalent. Additionally, the rate of decline in Mini-Mental State Examination (MMSE) scores over the 4 years subsequent to the diagnosis was the same for a subset of patients in the two groups, suggesting a shift in onset age with no change in rate of progression.
