Effects of level of processing on implicit and explicit tasks

The series of experiments presented in this article replicate the interaction that B. H. Challis and D. R. Brodbeck (1992) reported between list design (blocked or mixed) and level of processing for word fragment completion: The advantage for semantically processed words over shallowly processed words was greater when the conditions were blocked than when they were mixed on the study list. A similar interaction was found for perceptual identification (a data-driven implicit task) and priming in general knowledge questions (a conceptually driven implicit task). However, both data-driven and conceptually driven explicit tasks failed to reveal such a pattern.
