Reading time evidence for enriched composition.

Verbs like 'begin' and 'enjoy' appear to semantically select a complement that expresses an activity or an event (Jackendoff, R. (1997). The architecture of the language faculty. Cambridge, MA: MIT Press; Pustejovsky, J. Cognition 41 (1991) 47; Pustejovsky, J. (1995). The generative lexicon. Cambridge, MA: MIT Press). When these verbs occur with a complement that does not directly denote either an activity or an event (e.g. '... began the book' or '... enjoyed the book'), the complement must be type-shifted from an object to an activity to conform to the verb's semantic restrictions. We report an experiment in which self-paced reading times were found to be longer for complements that required type-shifting than for complements that directly matched the semantic restrictions of the matrix verb. This finding is argued to provide on-line evidence for a type of enriched lexical processing posited in recent lexical semantic research.

Learning new word meanings from context: a study of eye movements.

This study examined how readers establish the meaning of a new word from the sentence context during silent reading. Readers' eye movements were monitored while they read pairs of sentences containing a target word, context, and a word related to the target word. The target word varied in familiarity (high, low, or novel). The context varied in informativeness about the meaning of the target word (informative or neutral). The amount of time readers spent on the context depended on both the familiarity of the target word and the informativeness of the context. Readers spent additional time on the related word only when the context was neutral and the target was novel. These results indicate that readers were able to determine which areas of text were relevant and used the information to infer a meaning for the novel word.

Priming in sentence processing: intralexical spreading activation, schemas, and situation models.

A series of eye-tracking experiments investigated priming in natural language understanding. Intralexical spreading activation accounts of priming predict that the response to a target word will be speeded (i.e., primed) when strong associates appear prior to the target. Schema-based priming accounts predict that priming will occur when the target word is a component of an activated schema or script. Situation model accounts predict that priming will occur when a target word can be integrated easily into an evolving discourse representation. In separate experiments, we measured the effect of associated words, synonyms, and identity primes on processing times for subsequently encountered target words. Our designs crossed prime type (e.g., synonyms vs. unassociated words) with semantic plausibility (i.e., the target word was a plausible vs. an implausible continuation of the sentence). The results showed that identity primes, but not associates or synonyms, primed target words in early measures of processing like first fixation and gaze duration. Plausibility effects tended to emerge in later measures of processing (e.g., on total reading time), although some evidence was obtained for early effects of semantic plausibility. We propose that priming in naturalistic conditions is not caused by intralexical spreading activation or access to precompiled schemas.
