We demonstrate that unconscious processing of a stimulus property can be enhanced when there is a match between the contents of working memory and the stimulus presented in the visual field. Participants first held a cue (a colored circle) in working memory and then searched for a brief masked target shape presented simultaneously with a distractor shape. When participants reported having no awareness of the target shape at all, search performance was more accurate in the valid condition, where the target matched the cue in color, than in the neutral condition, where the target mismatched the cue. This effect cannot be attributed to bottomup perceptual priming from the presentation of a memory cue, because unconscious perception was not enhanced when the cue was merely perceptually identified but not actively held in working memory. These findings suggest that reentrant feedback from the contents of working memory modulates unconscious visual perception.

Are beauty and goodness the same? The relationship between beauty and goodness has long been a controversial issue in the fields of philosophy, aesthetics, ethics and psychology. Although many empirical studies have explored moral judgment and aesthetic judgment separately, only a few studies have compared the two. Whether these two judgments are two different processes or the same process with two different labels remains unclear. To answer this question, the present study directly compared the influence of facial attractiveness on judgments of moral goodness and moral beauty and revealed distinct contributions of imaging perceptions to these two judgments. The results showed that in the moral beauty judgment task, participants gave higher scores to characters with attractive faces compared with characters with unattractive faces, and larger P200 and LPP were elicited in the unattractive-face condition compared with the attractive-face condition; while in the moral goodness judgment task, there was no significant difference between the two conditions of either behaviour or ERP data. These findings offer important insights into the understanding and comparison of the processes of moral judgment and aesthetic judgment.
