Roland, Douglas William (Ph.D., Linguistics) Verb Sense and Verb Subcategorization Probabilities Thesis directed by Associate Professor Daniel S. Jurafsky This dissertation investigates a variety of problems in psycholinguistics and computational linguistics caused by the differences in verb subcategorization probabilities found between various corpora and(More)
Two patients with agrammatic speech and unimpaired comprehension are presented and contrasted. Case 1 had an infarction involving precentral gyrus, subjacent white matter, and posterior and superior aspects of the insula, largely sparing Broca's area. His speech was slow and dysarthric, consisting of short disconnected phrases with some omission of lexical(More)
The neural mechanisms underlying the processing of conventional and novel conceptual metaphorical sentences were examined with event-related potentials (ERPs). Conventional metaphors were created based on the Contemporary Theory of Metaphor and were operationally defined as familiar and readily interpretable. Novel metaphors were unfamiliar and harder to(More)
Background: This study investigates the role of lexical information in normal and aphasic sentence comprehension. Effects of verb biases in normal comprehension have been well documented in previous studies (e.g., Spivey-Knowlton & Sedivy, 1995; Trueswell, Tanenhaus, & Kello, 1993), but their role in aphasic language processing has largely been ignored(More)
Elicited narrative studies have shown that the underlying pragmatic factor of empathy is relatively preserved in aphasic speakers of Japanese and English (7 Japanese and 14 English-speaking aphasics of varied diagnostic types). Occasional "reversal errors" can be explained in terms of a conflict between the normal encoding of the empathic characteristics of(More)
This study investigates three factors that have been argued to define "canonical form" in sentence comprehension: Syntactic structure, semantic role, and frequency of usage. We first examine the claim that sentences containing unaccusative verbs present difficulties analogous to those of passive sentences. Using a plausibility judgment task, we show that a(More)
We explore the differences in verb subcategorization frequencies across several corpora in an effort to obtain stable cross corpus subcategorization probabilities for use in norming psychological experiments. For the 64 single sense verbs we looked at, subcategorization preferences were remarkably stable between British and American corpora, and between(More)
The preferential processing of concrete versus abstract nouns, and of active versus static or "quiet" verbs, was investigated using a lateralized lexical decision task in 32 normal and 4 commissurotomized subjects. Both groups of subjects showed the concreteness effect for nouns in both visual fields. The disconnected right hemisphere of two(More)
Multilingual aphasias are common because most people in the world know more than one language, but little is known of these syndromes except in patients who have had a stroke. We present a 76-year-old right-handed woman, fluent in English and Chinese, who developed anomia at age 70 and then progressed to aphasia. Functional neuroimaging disclosed mild left(More)
