As a spoken word unfolds over time, it is temporarily consistent
with the acoustic forms of multiple words. Previous behavioral
research has shown that, in the face of temporary ambiguity about
how a word will end, multiple candidate words are briefly acti-
vated. Here, we provide neural imaging evidence that lexical
candidates only temporarily consistent with the input activate
perceptually based semantic representations. An artificial lexicon
and novel visual environment were used to target human MT/V5
and an area anterior to it which have been shown to be recruited
during the reading of motion words. Participants learned words
that referred to novel objects and to motion or color/texture
changes that the objects underwent. The lexical items correspond-
ing to the change events were organized into phonologically
similar pairs differing only in the final syllable. Upon hearing
