Under normal circumstances, perception runs very fast and seemingly automatic. In just a few ms, we go from sensory features to perceiving objects. This fast time course does not only apply to general perceptual aspects but also to what we call higher-level judgements. Inspired by the study on 'very first impressions' by Bar, Neta, and Linz (2006, Emotion, 6, 269) the current research examined the speed and time course of three aspects of the aesthetic experience, namely beauty, specialness, and impressiveness. Participants were presented with 54 reproductions of paintings that covered a wide variety of artistic styles and contents. Presentation times were 10, 50, 100 and 500 ms in Experiment 1 and 20, 30 and 40 ms in Experiment 2. Our results not only show that consistent aesthetic judgements can be formed based on very brief glances of information, but that this speed of aesthetic impression formation also differs between different aesthetic judgements. Apparently, impressiveness judgements require longer exposure times than impressions of beauty or specialness. The results provide important evidence for our understanding of the time course of aesthetic experiences.From the moment we open our eyes, we clearly see the world around us and quickly extract information and meaning from it. Studies have found that when presented with real-world images, people are able to detect objects based on presentations as short as 50 ms and to recognize objects after only about 100 ms of presentation (see, e.g., Fei-Fei, Iyer, Koch, & Perona, 2007;Grill-Spector & Kanwisher, 2005). However, this fast processing comprises different stages. For example, Fei-Fei et al. (2007) found that before 40 ms, sensory-related features (light-dark) are dominant for people's perception of stimuli, while from around 50 ms of presentation, a shift to more object-related features occurs. Subjects are able to name very general object categories like manmade objects ('furniture', 'desk') and gradually get more detailed and accurate over time (Fei-Fei et al., 2007). Such a coarse-to-fine development of percepts has been found in many psychophysical studies (for a review, see Hegde, 2008) and is a core characteristic of the percept formation or microgenesis (Bachmann, 2000). What subjects perceive increases in detail the longer they see it, even if the image does not change. This happens on a very fast timescale (Fei-Fei et al., 2007;Hegde, 2008). A very vivid illustration that such speed and differentiated time course do not pertain only to general perceptual and identification aspects, such as colour or object category, but also to judgemental aspects *Correspondence should be addressed to M.
