Two experiments indicated that sentence verification times were significantly longer when a discrepancy between target sentence and context was in the syntactic presupposition, rather than in the assertion. Findings are best explained by a structural hypothesis, not by strategies designed to locate given and new information. (Author/CP)

Reaction time to detect a phoneme target in a sentence was faster when the target-containing word formed part of the semantic focus of the sentence. Sentence understanding was facilitated by rapid identification of focused information. Active search for accented words can be interpreted as a search for semantic focus. (Author/RD)

The speed at which sentences with various kinds of violations could be rejected was studied. Compatible with the sequential model was the finding that noun-verb and adjective-noun double violations did not result in shorter reaction times than noun-verb single violations, although double violations were judged less acceptable.
