Average search times for detecting targets on the original or sharpened mammogram images, after adapting to the original images or sharpened images. Points plot the mean reaction times for individual fatty (red squares) or dense (blue circles) images. Top: comparison of search times on the sharpened vs original versions of the images after adapting to the original mammogram images (left) or sharpened images (right). Bottom: search times for adaptation on the sharpened images vs the original images, compared for the original test images (left) or sharpened test images (right)
