“…AH polygons were asymmetrical random shapes, which had originally been constructed by connecting random points on a 100 X 100 grid (Attneave & Arnoult, 1956). Previous research (Eisenman, 1965a(Eisenman, , 1965b(Eisenman, , 1966(Eisenman, , 1967a(Eisenman, , 1967bEisenman, Hannon, & Bernard, 1966) had suggested that the polygons employed in the present study reveal differential preference for such diverse groupings as schizophrenics versus nonschizophrenics, firstborns versus later borns, and other dichotomies.…”
