Each observer responded on an eight-point confidence scale whether there was a Gabor luminance patch (SNR = 3.5) in the middle of the black box. (D) Schematic of our search task. Each observer responded on an eight- point confidence scale whether there was a Gabor luminance patch (SNR = 7.88) anywhere in the image.
