… and differences in luminance contrast between spatial frequencies on rapid scene categorization.
In Experiment 1, we used sequences composed of six filtered scenes, assembled from …

… In the rapid animal/nonanimal categorization task used here, subjects could still perform
largely above chance level with very low luminance contrast photographs which might only …

… -square contrast (luminance and color) as well as mean luminance. All images were fit with
a circular linear edge-blurred window to obscure the square frame of the images, thereby …

… We used the same critical radius values, and we chose stimuli from similar scene categories
and we processed them in a similar way (equalizing luminance and contrasts, using the …

… that object information is used for scene categorization. Taken together, we show that global
scene properties are useful but not sufficient for fast scene categorization. Instead, localized …
