Abstract
One of the long-standing questions in psycholinguistics has been
the relationship between comprehension and production. Theories
of language production and comprehension typically propose that word
retrieval involves the selection of at least two levels of lexical information,
semantic representations and word-forms (phonological and orthographic
representations). The results from five experiments tested whether semantic
and word-form representations are shared between production and
comprehension or separate. The experiments used a variation of the
standard priming task, with word-pairs as the primes and pictures as
the probes. The same probe pictures were used in all of the experiments.
The word-pair trials consisted of one word which was produced and the
other ignored. The logic was that produced words were both comprehended
and produced, but ignored words were only comprehended. If lexical
representations are shared, then both produced and ignored related primes
should result in priming of the pictures on the probe trials. Experiment 1
demonstrated repetition priming for both produced and ignored primes,
demonstrating that the ignored primes were processed. Experiments 2
and 3 demonstrated that taxonomically related primes slowed probe picture
naming for both produced and ignored primes, supporting a model in
which semantic representations are shared by production and comprehension.
Experiments 4 and 5 used phonologically related primes and demonstrated
that produced primes slowed picture naming but ignored primes did not.
These results support a model in which the word-forms retrieved by ignored
primes are represented separately from the word-forms retrieved for naming
the probe pictures.
