Verb argument structure effects in aphasia are different at single-word versus sentence level

A reconceptualization of sentence production in post-stroke agrammatic aphasia: the Synergistic Processing Bottleneck model

“…Consistent with this, in constrained sentence production tasks where participants are required to retrieve the verb and its arguments to produce a complete sentence, sentences with complex VAS verbs are less well-formed and less complex compared to sentences with simpler VAS verbs (e.g., Dragoy and Bastiaanse, 2010;Malyutina and Zelenkova, 2020). However, it is unclear if this finding is specific to PSA-G because studies either report single dissociations (e.g., Dragoy and Bastiaanse, 2010), insufficiently characterize the morphosyntactic production deficit of PSA-G ("nonfluent" participants in Malyutina and Zelenkova, 2020), or find no differences across aphasia subtypes (Jonkers and Bastiaanse, 1996;Caley et al, 2017;Malyutina and Zelenkova, 2020). While some studies have noted that syntactic complexity has an additive effect with VAS complexity (e.g., Bastiaanse andvan Zonneveld, 1998, 2005), other studies have not found this effect (Kok et al, 2007).…”

Word finding and lexical–semantic disorders.

“…Thompson and colleagues (2012) reported that individuals with agrammatic stroke-induced aphasia were more impaired when retrieving verbs than nouns. Likewise, grammatically complex verbs were especially affected in verb naming (Malyutina & Zelenkova, 2020). These findings suggest a role played by the left inferior frontal region in lexical selection, particularly for verbs, which may be associated with "controlled semantic retrieval and/or competitive selection during word production" (Schwartz et al, 2009, p. 3423).…”
