Резюме	Thin-slicing, established by Ambady and Rosenthal's 1992 meta-analysis, is the finding and method that judgments based on very brief samples of expressive behavior -- sometimes only a few seconds -- can predict consequential interpersonal outcomes with surprising accuracy. In the paradigm, short clips (thin slices) of a target's nonverbal and verbal behavior are shown to naive observers who rate a trait or quality, and these ratings are correlated with an independent criterion such as teaching effectiveness, clinical skill, rapport, or relationship outcomes. Ambady and Rosenthal showed across many studies that thin-slice judgments are reliable and valid, and that lengthening the observation often adds little accuracy. The method became a key tool for studying interpersonal perception, first impressions, and the information carried by brief behavioral displays, while also raising questions about the bases and biases of rapid social judgment.	The reverse correlation task is a data-driven method for visualizing the mental representations people hold of social categories and traits, such as what a trustworthy, dominant, or criminal face looks like in the mind's eye. Adapted to social perception by Dotsch and Todorov in 2012, the technique superimposes random visual noise on a base face to create many slightly different images, and asks participants to repeatedly choose, from pairs, the image that best fits a target trait. By averaging the noise patterns from the chosen images, the researcher produces a classification image -- a picture that reveals the visual features the participant's mind associates with the trait, without the experimenter ever specifying those features in advance. Independent raters then judge the classification image to confirm it conveys the intended trait. The method made it possible to render otherwise hidden mental representations and biases as concrete, testable images.
