This dissertation explores how items encountered in the comprehension of language are stored in memory and subsequently accessed. Processing and comprehending language frequently requires the retrieval of items in memory so that a current linguistic element can be assigned an interpretation. For example, in a sentence such as "Miles loved his…

Purpose: In this study, we sought to identify critical linguistic markers that can differentiate sentence processing of individuals with mild cognitive impairment (MCI) from the sentence processing of normal-aging populations by manipulating sentences' linguistic complexity. We investigated whether passive sentences, as linguistically complex…

We present a new dorsal-ventral stream framework for language comprehension which unifies basic neurobiological assumptions (Rauschecker & Scott, 2009) with a cross-linguistic neurocognitive sentence comprehension model (eADM; Bornkessel & Schlesewsky, 2006). The dissociation between (time-dependent) syntactic structure-building and…

Recent research has demonstrated that knowledge of real-world events plays an important role in guiding online language comprehension. The present study addresses the scope of event knowledge activation during the course of comprehension, specifically investigating whether activation is limited to those knowledge elements that align with the local…

Producing a sentence involves encoding a preverbal message into a grammatical structure by retrieving lexical items and integrating them into a functional (semantic-to-grammatical) structure. Individuals with agrammatism are impaired in this grammatical encoding process. However, it is unclear what aspect of grammatical encoding is impaired and…

Previous evidence suggests that when speakers produce sentences from memory or as picture descriptions, their choices of sentence structure are influenced by how easy it is to retrieve sentence material (accessibility). Three experiments assessed whether this pattern holds in naturalistic, interactive dialogue. Pairs of speakers took turns asking…

Gibson's Dependency Locality Theory (DLT) [Gibson, E. 1998. "Linguistic complexity: locality of syntactic dependencies." "Cognition," 68, 1-76; Gibson, E. 2000.

Study investigated the processing of ambiguous words that varied in frequency of use of their multiple interpretations. Results indicate that, whereas lexical access is an autonomous process, selection of the appropriate interpretation is a post-lexical process that is influenced by frequency information and context.

Investigates the availability of surface representations for the interpretation of verb-phrase ellipsis. Results show that an elliptical verb phrase is most easily interpreted if its antecedent is in the immediately preceding sentence and that this can not be explained in terms of the unnaturalness of the passages with distant antecedents.

Investigated the source of agrammatic aphasic patients' difficulty comprehending semantically reversible sentences. Found approximately equal distributions of three distinct patterns. Results conflict with explanations of comprehension failure which state that a single pattern of performance on sentence structures characterizes comprehension of…
