【 摘 要 】

Look very briefly at the picture on the next page (Figure ​(Figure1);1); what do you see? Decades of research has shown that it is possible to extract the gist of a scene very quickly (Potter, 1975; Friedman, 1979); even from the briefest of glances you could probably classify this scene as some sort of race. Other research has shown that some categories of objects, people and animals in particular, can also be detected from very brief exposures (Thorpe et al., 1996; Joubert et al., 2007). It may even be possible to infer from the features of a scene some properties of these objects, such as a person's gender and perhaps their emotion (Schyns and Oliva, 1999). Actions can also be characterized by relatively simple features (see Kozlowski and Cutting, 1977 and Wang et al., 2009, for two very different approaches), with the pose adopted by someone running being especially distinctive. So in addition to detecting that there were people in this scene, you could probably also discern that these people were women and that they were running. Combining these pieces of information might therefore have led you to a simple “gist” level of interpretation—a women's track meet.
