How does Hebb both ‘divide’ and ‘conquer’ speech perception and production?

Abstract

A particular merit of Hickok's integrated (H)SFC model lies in the mechanistic detail with which psycholinguistic, motor control and neuroscientific perspectives on speech production are bridged, offering a much-welcomed alternative to traditional views on how concepts are translated to speech in the human mind. However, there seems to be an inconsistency between the dynamics engendering the mature (H)SFC model and those which allow the model to develop this architecture. Concretely, I question how the proposed (H)SFC model, which becomes functionally connected through Hebbian-like learning, provides the adult speaker with a brain network where ventral and dorsal streams dissociate.
