In Experiment 1, which manipulated perceptual load (1, 2, or 4 words) at encoding, somewhat ambiguous results were found: Although there was no reliable effect of encoding load, there also was not reliable implicit memory for Load 4 words. In Experiment 2, which manipulated the intention of participants to process or not process words at encoding, clear support for a controlled processing view was found: A reliable effect of intention was found and there was not reliable implicit memory for words that participants did not intend to process at encoding.
