Art of the State

Currently I'm very busy in learning the formal foundations of linguistics (Set Theory, Relations), programming (Python) and computational linguistics (Maximum Likelihood Estimation, Context Free Grammars).

I got an e-mail. Really. From a reader. By the way, it's my first; that's why I'm quite enthusiastic. He suggested to introduce my readers (do I have any?) to his blog Neuropolitics. Well, well, I read the first sentences and decided to mention it in this post. Form your own opinion.

Perhaps I'm going to write about the foundations of Natural Language Processing or upload some Python code which could be used to play with strings. Mostly harmless, not really meaningful code. I don't think that I'll have time for something else anyway.

Time's running, running out

Unfortunately, I don't have time to blog for the time being. I study natural language processing, which is very intense. So give me a week or two and I'll come back.

7. Syntactic persistence is the tendency for speakers to produce sentences using similar grammatical patterns and rules of language as those they have used before. Although the way this occurs is not well understood, previous research has indicated that this effect may involve a specific aspect of memory function. Memory is made up of two components: declarative and procedural. Declarative memory is used in remembering events and facts. Procedural memory helps us to remember how to perform tasks, such as playing the piano or riding a bike. A recent study suggests that the common phrase, "it's so easy, it's like riding a bike" should perhaps be replaced with "it's so easy, it's like forming a sentence.": Un-total recall: Amnesics remember grammar, but not meaning of new sentences

Points of Interest 17. September, 2008

I got a bit picky about the Points of Interest I choose these days; so less is more. A problem which occured while writing this and which is bothering me: What's the difference between:

a) It is not
b) It isn't
c) It's not

I think the first is the most emphasised because there is no contraction at all. The second emphasises the subject - due to the contraction of "is not" the stress shifts to "It". The third emphasises the negation because the stress lies on "not". Language Hat had a post about this in 2005.

1. An interesting article about the neurobiology of a hallucination based on Ffytche, D. (2008). The hodology of hallucinations. Cortex 44: 1067-1083. DOI: 10.1016/j.cortex.2008.04.005:

"In the EEG experiments, the activity recorded from two of the electrodes was found to become sychronous whilst the subjects were hallucinating. [...] Ffytche hypothesizes that the changes in connectivity could be due to changes in the firing mode of the thalamo-cortical connections [...] Overall, Fytche's findings suggest that hallucination cannot be explained by a topological or hodological explanation alone, but instead by a combination of the two. [...]"

One word != one number

Earlier this year a study was conducted by researchers from the University of Melbourne and University College London - namely Brian Butterworth, Robert Reeve, Fiona Reynolds and Delyth Lloyd. Children of two indigenous communities were tested for their numeracy skills; one from Tanami Desert and the other from Groote Eylandt. Another group were indigenous preschool children from Melbourne. Here's a map of the locations:

The results showed clearly that the children of indegenious communities - who have no words or even gestures for numbers - have numeracy skills equal to native English speaking children. So numeracy is not based on culture or language but probably an innate facility.
