In this article I argue that both bare infinitival and participial com
plements of perception verbs in English are clausal constituents heade
d by the functional category Aspect, and differ only with respect to t
heir aspectual value. Further, I argue that perception verbs license a
spectual complements by virtue of being able to function as event cont
rol predicates, that is, they allow a control relation to be establish
ed between their own and the event argument provided by the predicate
of the complement clause. It is shown that the entire cluster of synta
ctic and semantic properties that characterize direct perception const
ructions follows from the proposed analysis, in conjunction with indep
endently motivated principles of grammar.
