Content without a frame? The role of vocabulary biases in speech errors

Constraints on the types of speech errors observed can be accounted for by a frame/content distinction, but connectionist modeling shows that they do not require this distinction. The constraints may arise instead from the statistical properties of our language, in particular, the sequential biases observed in the vocabulary. Nevertheless, there might still be a role for the frame/content distinction in syntactic planning.
