This paper examines the syntactic processing of structural ambiguities
in German verb-second (V2) clauses. It is argued that the proposal of
Grimshaw (1991, 1993) that CP and IP are verbal ''extended projection
s'' allows an incremental parse of these ambiguities which is consiste
nt with the principles of simplicity (no vacuous structure building) a
nd structural determinism (computed dominance and precedence relations
cannot be altered by parser-internal operations) proposed in Gorrell
(1995). It is argued that the ambiguities discussed here provide evide
nce against the hypothesis that the parser's initial attachment decisi
ons follow from a maximal-licensing principle rather than a preference
for minimal structure (Pritchett, 1992). Further, it is argued that,
contra Fodor and Inoue (1994), theories of syntactic processing must n
ot only incorporate some mechanism for resolving conflicts between new
input and computed structure, but also distinguish the comparative co
sts of different reanalysis types.
