------

This talk presents a particular conceptualization of human language
understanding as information processing. From this viewpoint,
understanding a sentence word-by-word is a kind of incomplete perception
problem in which comprehenders over time become more certain about the
linguistic structure of the utterance they are trying to understand. The
Entropy Reduction hypothesis holds that the scale of these
certainty-increases reflects psychological effort.

This claim revives the application of information theory to
psycholinguistics, which languished since the 1950s. But in contrast to
that earlier work, modern applications of information theory to
language-understanding now use generative grammars to specify the
relevant structures and their probabilities. This representation makes
it possible to apply standard techniques from computational linguistics
to work out weighted "expectations" about as-yet-unheard words. The talk
exemplifies the general theory using examples from Chinese, Japanese &
Korean. The prenomial character of relative clauses in these languages
is an important test case for any general cognitive theory of sentence
processing.
