Fig. 4

Diameter size of 1st encircled image for Dalí and Rorschach stimuli by group (A). Diameter size of 1st encircled image for Dalí without number 7 and Rorschach without number 5 (B) for EG and CG. Differences between groups were significant in both cases. Fundamental Spatial Frequencies for both Dalí (C) and Rorschach (D) pictures. Notice the parallelism of the linear tendency lines (C, D). Observe that most of the FSF for EG are in the range of 0.06–0.07 cpd, spatial frequency contrast sensitivity values yet to be measured and reported in the literature (C, D)
