“…If these aphasics suffer from retrieval problems for verbs, as is often suggested in the literature (e.g. Cheng & Bates, 1998;Miceli, Silveri, Villa, & Caramazza, 1984;Zingeser & Berndt, 1990), then a frequency effect might be expected. Although a frequency effect has often been shown for retrieval deficits for nouns, it has been mentioned before that such an effect for verbs does not exist (see, e.g., Jonkers, 1998).…”

“…1 Several studies reveal that Broca's aphasics are poor in action naming compared to object naming (Basti-aanse & Jonkers, 1998;Kohn, Lorch, & Pearson, 1989;Zingeser & Berndt, 1990), that they produce a relatively small number of verbs in spontaneous speech (Saffran, Berndt, & Schwartz, 1989;Thompson, Shapiro, & Schendel, 1995), and that the verbs that are produced often lack inflection (Bastiaanse & Jonkers, 1998;Saffran et al, 1989;Thompson et al, 1994). Most studies on the grammatical aspects of verb production in Broca's aphasia have been done in English, which is not the most suitable language for such research because the inflectional paradigm is very limited and there is little variation in the position of the verb.…”

“…In addition, neurolinguistic research has shown that these two parts of speech can be selectively compromised in different aphasic populations in both connected speech production and picture naming (Berndt and Zingeser, 1991;McCarthy and Warrington, 1985;Miceli et al, 1984Miceli et al, , 1988Myerson and Goodglass, 1972;Zingeser and Berndt, 1990).Aphasic patients with more frontal lesions (e.g., with Broca's aphasia) tend to have greater difficulties with verbs, while aphasic patents with more posterior damage (e.g., with Wernicke's aphasia and anomia) tend to have greater difficulties with nouns. Noun/verb differences have also been seen in other neurological populations.…”

To mind the mind: An event-related potential study of word class and semantic ambiguity

The goal of this study was to jointly examine the effects of word class, word class ambiguity, and semantic ambiguity on the brain response to words in syntactically specified contexts. Four types of words were used: (1) word class ambiguous words with a high degree of semantic ambiguity (e.g., 'duck'); (2) word class ambiguous words with little or no semantic ambiguity (e.g., 'vote'); (3) word class unambiguous nouns (e.g., 'sofa'); and (4) word class unambiguous verbs (e.g., 'eat'). These words were embedded in minimal phrases that explicitly specified their word class: "the" for nouns (and ambiguous words used as nouns) and "to" for verbs (and ambiguous words used as verbs). Our results replicate the basic word class effects found in prior work (Federmeier, K.D., Segal, J.B., Lombrozo, T., Kutas, M., 2000. Brain responses to nouns, verbs and class ambiguous words in context. Brain, 123 (12), 2552-2566), including an enhanced N400 (250-450ms) to nouns compared with verbs and an enhanced frontal positivity (300-700 ms) to unambiguous verbs in relation to unambiguous nouns. A sustained frontal negativity (250-900 ms) that was previously linked to word class ambiguity also appeared in this study but was specific to word class ambiguous items that also had a high level of semantic ambiguity; word class ambiguous items without semantic ambiguity, in contrast, were more positive than class unambiguous words in the early part of this time window (250-500 ms). Thus, this frontal negative effect seems to be driven by the need to resolve the semantic ambiguity that is sometimes associated with different grammatical uses of a word class ambiguous homograph rather than by the class ambiguity per se.

“…Verb production; Unaccusatives; Syntactic deficits; Agrammatism It has been well documented in the literature that some individuals with aphasia, particularly those showing deficit patterns consistent with a diagnosis of Broca's aphasia with agrammatism, evince greater difficulty producing verbs as compared to nouns (Berndt, Mitchum, Haendiges, & Sandson, 1997; Miceli, Silveri, Nocentini, & Caramazza, 1988;Miceli, Silveri, Villa, & Caramazza, 1984; Thompson et al, l995b;Zingeser & Berndt, 1990). While recent research focused on determining the nature of verb production deficits has shown that several factors may play a role in this production difficulty, including frequency and familiarity (Kemmerer & Tranel, 2000), imageability (Bird, Howard, & Franklin, 2000), and semantic factors (Breedin, Saffran, & Schwartz, 1998), the number of syntactic arguments associated with the verb and corresponding participant roles has been shown to influence verb production in several studies (Jonkers & Bastiaanse, 1996Kegl, 1995;Kemmerer & Tranel, 2000;Kim & Thompson, 2000;Kiss, 2000 Lange, Schneider, & Shapiro, 1997; Thompson, Shapiro, Li, & Schendel, 1995a).…”

This study examined patterns of verb production in narrative samples of eight individuals with agrammatic aphasia and seven education-and age-matched normal subjects. Comprehension and constrained production of two types of intransitive verbs-unaccusatives whose argument structure triggers a complex syntactic derivation and unergatives that are considered syntactically simple-was also tested. Results showed that in narrative tasks a hierarchy of verb production difficulty as seen in previous studies [Aphasiology 11 (1997) 473; Brain and Language 74 (2000) 1] emerged for the aphasic participants, with a preference noted for production of verbs with a fewer number of arguments. Both normal and agrammatic subjects also showed fewer productions of unaccusative intransitive verbs in their narrative samples as compared to other verb types (supporting findings reported by Kegl [Brain and Language 50 (1995) 151]. In contrast to relatively spared comprehension of both unaccusative and unergative intransitives, the aphasic participants showed significantly greater difficulty producing unaccusatives as compared to unergatives in the constrained task. These findings suggest that deficits in accessing verbs for production are influenced by the verb's argument structure entry and led to what is referred to as the 'argument structure complexity hypothesis'. When verbs become more complex in terms of the number of associated arguments or when the argument structure entry of the verb does not directly map to its s-structure representation, production difficulty increases.

For example, Thompson et al. (1995aThompson et al. ( , 1997 found that agrammatic aphasic subjects with verb retrieval difficulty in both verb naming and in sentence production showed a pattern of verb production deficit in both tasks related to the number of arguments associated with the verb.
