On priming by a sentence context.

Previous investigations of sentence context effects (SCEs) on word-naming time have uncovered a pattern of facilitation dominance. Another finding has been that words that are more difficult to recognize in isolation display larger SCEs than easier words. The present experiments with 384 undergraduates showed SCEs to be robust and eliminated several alternative explanations. Two experiments demonstrated the appropriateness of the neutral condition used to assess facilitation and inhibition. Another showed that SCEs did not depend on the procedure used. It was shown that manipulations that were designed to affect S strategies did not change the pattern of results. In 3 experiments, an interaction between stimulus quality and content condition was obtained. The interaction replicated across 2 forms of stimulus degradation, but only 1 form increased inhibition effects as well as facilitation effects. Other inconsistencies between previous SC experiments in the magnitude of the inhibition effects observed were resolved by showing that an SC produced more inhibition in the lexical decision task than in the naming task. It was demonstrated that the 2 tasks produced different amounts of inhibition when the same stimuli were used. Sentence integration processes that occurred after lexical access appeared to be responsible for some of the inhibition observed in lexical decision tasks.
