What is the aspectual representation of verbs and how is that representation
used to construct the aspectual interpretation of a sentence during online
sentence processing? In this paper we use psycholinguistic techniques to
address both these questions. In the first experiment, a processing correlate
of telicity is identified by manipulating verbal telicity (inherently telic vs.
unspecified verbs) and direct object quantization, finding a principled delay
in the use of these verbs’ aspectual representation in which both the verb
and its internal argument are required before the comprehension system can
commit to a telic or atelic interpretation. In the second experiment, this
processing correlate reveals no differences in processing between inherently
atelic and unspecified verbs, delayed or otherwise. We argue that together
these experiments support theories that distinguish between two verb classi-
fications, a class of inherently telic verbs and a class of unspecified verbs,
but not those that include a class of inherently atelic verbs
