Abstract
When producing words, lexical access proceeds through semantic and
phonological levels of processing. If phonological processing begins based
on partial semantic information, processing is cascaded; otherwise, it is
discrete. Semantically processed words that are not produced should
exert phonological effects only if processing is cascaded. In three experiments,
speakers named picutres of objects with homophone names ("ball"), while
auditory distractor words were heard beginning 150 ms prior to picture onset.
Distractors speeded picture naming (compared to controls) only when related
to the non-depicted meaning of the picture (e.g., "dance"), suggesting
that semantically processed unproduced words can exert phonolgical effects,
supporting the cascaded prediction. Distractors slowed picture naming only
when categorically ("frisbee"), as opposed to associaatively ("game") related
to the depicted picture meaning. To help explain the results, an interactive
activation model implementing cascaded processing and representing competitive
and associative relations is presented.
