Pulvermüller's Hebbian model implies that an impairment in the word form system will affect phonological articulation and phonological comprehension, because there is only a single representation. Clinical evidence from patients with word-form deafness demonstrates a dissociation between input and output phonologies. These data suggest that auditory comprehension and articulatory production depend on discrete phonological representations localized in different cortical networks.
