The phonology-morphosyntax interface: affixed words in agrammatism

Abstract:
In three experiments with nondysarthric agrammatics, we explored the association between phonology and morphosyntax. (1) Contrasting phonological and nonphonological factors on inflectional-affix production of English verbs across three tasks in eight agrammatics, longer stem-syllabic length and stem-final-CC status resulted in poorer affix-production. (2) Studying verb inflections in six agrammatic Spanish-speakers, affix-length and affix-stress correlated with poorer repetition, as did low affix frequency. (3) Four English-speaking agrammatics read aloud and repeated derived words varying in syllable-length and stem-stress reassignment; both contributed independently to word-production difficulty. Phonological complexity of affixes and stems appears to reduce resources for morphological processing in nondysarthric agrammatics.
