Responses were categorized according to whether a stimulus was learned in the living/non-living task and recognized in the test phase.

Cell A refers to successful recognition, which is served by implicit and explicit processes. Cell C lacks the explicit recognition process; however implicit perceptual processes should occur due to the repeated exposure to the learned stimulus. Cell D refers to new stimuli that had not been seen before and were not recognized in its degraded form.Conducted contrasts were A vs. D, reflecting successful object recognition; A vs. C reflecting explicit recognition aspects, and C vs. D reflecting implicit perceptual processes.
