Projected slides of 112 coherent or jumbled real-world scenes for single-object detection by 36 introductory psychology students. The speed at which objects were detected was reduced when the scene was jumbled. Jumbling was most disruptive when the target object was not in the scene but had a high probability of occurring in that kind of scene. Results are discussed in terms of the possible role played by schemas in the processing of information from real-world scenes. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
