Its lucky for us that the Chinese let you out of the country, David. Police
interrogation seems a dreadful circumstance in which to be taught the
local version of Grice's maxim.
The kinds of experiment you describe were a hot topic of discussion in the
1930's and I recall that the results were seen as crucial to arguments
between
gestalt and american behaviorist learning theorists. I have not read that
book for a long time, but will take a look at the passage you cite. Your
account of the
difference between that of the kids and fish (I recall that chickens behave
like the fish) seems interestingly plausible, in so far as I understood it.
What does the
&thing* construction mean?
