Results of (left) Experiments 1 and (right) 2. The mean elevations in contrast threshold (log scaled) as a function of the spatial frequency or orientation of the target stimulus (Gabor patch or orientation band-pass filtered noise) that was suppressed with CFS are plotted. The inset in the left graph pertains to threshold elevations for detecting low or high spatial frequency band-pass filtered face images. Error bars denote the standard error of the mean (SEM).
