Integrating psycholinguistic and motor control approaches to speech production: where do they meet?

To integrate psycholinguistic and motor control approaches to speech production, Hickok proposes the hierarchical state feedback control (HSFC) model. Here, I contest the direct mapping between lemmas and syllable motor programmes proposed by Hickok, and argue that this mapping proceeds indirectly via morphemic and phonological word representations. The results of computer simulations suggest that phoneme-based mapping is a viable alternative to the lemma-based mapping of the HSFC model
