The interaction of veracity and syntax in the processing of sentences1

The reaction times of 80 Ss in judging sentences true or false with respect to pictures were analyzed, and it was noted (a) that true sentences containing an expected surface structure required less time than false sentences of the same structure, (b) that latencies to true sentences containing an unexpected surface structure were longer than latencies to the same sentences when their structure was identical to that of previous sentences, and (c) that transitive-verb constructions appeared easier to judge than predicate nominatives of the same length.
