1. Listeneres can only keep up with the rapid rate of speech (5 syllables/second) because they anticipate the missing possible syllables of the word. A new study conducted by scientists of the University of Rochester and Georgia Tech showed that this is not only true for the phonology but also the semantics of words: Scientists watch as listener's brain predicts speaker's words & Neural correlates of partial lexical activation

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.
