This book examines the role of syntax in theories of sentence
comprehension, and argues for a distinct processing component which is
devoted to the recovery of syntactic structure and which utilizes the
contrasting types of information found within a Government-Binding grammar.
Paul Gorrell contrasts the primary relations (dominance and precedence) and
secondary relations (case assignment, theta-role assignment, etc.) in a
phrase-structure tree, and shows how this computational distinction of
information types is reflected in the internal structure of the parser,
which consists of two sub-components: a structure builder (responsible for
creating nodes in a tree and positing primary relations between them), and
a structure interpreter (responsible for analysing the tree in terms of
secondary relations). This model can also predict garden-path phenomena in
the processing of verb-final clauses.
