Extending evidence for the rapid revision of mental representations of what other people are like, we explored whether people also rapidly revise their representations of what others look like. After learning to ascribe positive or negative behavioral information to a target person and generating a visualization of their face in a reverse-correlation task, participants learned new information that was (a) counter-attitudinal and diagnostic about the person's character or (b) neutral and non-diagnostic, and then they generated a second visualization. Ratings of these visualizations in separate samples of participants consistently revealed revision effects: Time 2 visualizations assimilated to the counter-attitudinal information. Weaker revision effects also emerged after learning neutral information, suggesting that the evaluative extremity of visualizations may dilute when encountering any additional information. These findings indicate that representations of others' appearance may change upon learning more about them, particularly when this new information is counter-attitudinal and diagnostic.
