C.M. is an agrammatic patient who on assessment tests shows a disproportionate difficulty when producing verbs compared with nouns. In three experiments, we investigated whether C.M. also has difficulties with nouns referring to events and whether event nouns and verbs show similar patterns of disruption. Experiment 1 suggested that she is sensitive to argument structure complexity and has a greater impairment in the production of event nouns and verbs than object nouns. Experiment 2 revealed that C.M. finds derivationally complex words, such as event nouns, difficult to produce. However, morphological complexity does not completely explain C.M.’s problems with event nouns. In Experiment 3, an assessment of C.M.’s ability to use different aspects of semantic and syntactic knowledge relative to event nouns and verbs showed an almost identical performance with the two types of words.

Abstract

C.M. is an agrammatic patient who on assessment tests shows a disproportionate difficulty when producing verbs compared with nouns. In three experiments, we investigated whether C.M. also has difficulties with nouns referring to events and whether event nouns and verbs show similar patterns of disruption. Experiment 1 suggested that she is sensitive to argument structure complexity and has a greater impairment in the production of event nouns and verbs than object nouns. Experiment 2 revealed that C.M. finds derivationally complex words, such as event nouns, difficult to produce. However, morphological complexity does not completely explain C.M.’s problems with event nouns. In Experiment 3, an assessment of C.M.’s ability to use different aspects of semantic and syntactic knowledge relative to event nouns and verbs showed an almost identical performance with the two types of words. The relevance of the findings with respect to models of word production is considered.
