Title: Re: Two questions I was asked
Thanks for your note. About the tritone paradox, you might want
to offload our recent article:
Deutsch, D., Henthorn, T., & Dolson, M.
Speech patterns heard early in life influence later perception of the
tritone paradox. Music Perception, 2004, 21, 357
which is posted as a PDF document under 'Publications' on
my website http://psy.ucsd.edu/~ddeutsch
We studied perception of the tritone paradox in two groups of
subjects who had come to the U.S. from Vietnam. The first group had
arrived as infants or children; they now spoke perfect English but
were not fluent speakers of Vietnamese. The second group had arrived
in the US as adults; they spoke primarily Vietnamese but were not
fluent speakers of English. We also tested a control group of native
speakers of English who were born and grown up in California,
and whose parents were also native speakers of English who were born
and grown up in California. The two Vietnamese groups were strikingly
similar in the way they heard the tritone paradox, and the data from
both Vietnamese groups differed significantly from the 'native
English-speaking Californian' group. We conclude that perception of
the tritone paradox is heavily influenced by speech patterns heard
early in life.
In this study we did not find evidence of secondary humps
in the plots produced by bilingual speakers - such as one
might reasonably expect to find, and I believe were found by Magdalene
Chalikia in her studies of perception of the tritone paradox by
bilingual subjects. It may well be that the relative influences of the
first and second languages (or dialects - since this line of reasoning
applies to dialects also) depends on the nature of the languages or
dialects being studied - in addition to other factors.
Concerning handedness and the octave illusion, you might
want to offload the following two articles that are posted as
PDFs on the same 'Publications' web page:
Deutsch, D. An auditory illusion.
Nature, 1974, 251, 307-309.
Deutsch, D. The octave illusion in relation
to handedness and familial handedness background.
Neuropsychologia, 1983, 21, 289-293.
Both these articles show strong handedness correlates with the
octave illusion. I tested for gender differences, but didn't find
Please let me know if you have any trouble offloading these
articles, and I'll send you the PDFs directly.

This year I played a few examples from Diana Deutsch's CD, and
them some of the notes for components that need headphones, or
take too long.
At the end of the lecture one of the students cam and asked a
of questions, which surprised me as particular student has not said
word for 12 weeks.
Anyway the two questions are:
a) Related to the Tritone paradox, if the language of the listener
affects the rising or falling interpretation, what happens to
bi-lingual listeners, especially those who have been brought up as
bi-lingual? Student in question is certainly of this kind.
the first language would dominate, but said I would ask.
b) The second question related to the effect of handedness to the
octave paradox. Handedness has been related to brain
dominance, and so has the gender differences. Is there any
difference in this paradox?
Apologies if these are not very clear; I am not a psychologist and
this is way outside my main areas. But I did promise the student
I would ask.
