It is often assumed that input and
Universal Grammar (UG) are mutually exclusive components in
theories of language acquisition. However, this is not an
accurate interpretation of the theoretical and empirical work
in the UG tradition (Chomsky 1965, Wexler & Culicover
1980, Berwick 1985, Pinker 1999, Yang 2002). In this talk, we
show that input effects are compatible with, and can be
fruitfully incorporated into a UG based quantitative approach
to acquisition (e.g., Yang 2004; Trends in Cognitive Science).
Moreover, input effects can play an important role in
differentiating competing accounts of the learner's grammar
system. Finally, we discuss the implications of these findings
for second language acquisition research.
Verbal aspect in SLA: Knowing it and using it is not the
same

Verbal aspect has been of long-standing
interest in SLA, with previous work focusing on how learners
acquire formal restrictions on the combination of grammatical
and lexical aspect. Yet aspect has repercussions in
native-language processing that go far beyond form-meaning
mappings: native speakers use aspect in its function as an
indicator of event structure to guide their probabilistic
expectations about discourse coherence and continuations
(Kehler et al., 2008). Here we ask whether L2 learners who
have mastered the relevant form-meaning mappings similarly
draw on aspect in discourse processing. Results from Japanese-
and Korean- speaking learners of English indicate a diminished
effect of aspect in the non-native compared to the
native-speaker group. We hypothesize that this is due to
non-native speakers’ Reduced Ability to Generate Expectations
during language processing, a hypothesis built on the premise
that static knowledge (formal or functional) is not enough—the
critical point is the dynamic deployment of this knowledge in
the course of language processing.
