“…Several such classifications have recently been developed. Researchers have investigated the complexity of stimuli (Attneave, 1957;Berlyne, 1958), the amount of information or redundancy in patterns (Attneave, 1954(Attneave, , 1955Klemmer & Frick, 1953), and the number VISUAL SYMMETRY 291 of alternatives that patterns possess (Garner, 1962(Garner, , 1966(Garner, , 1970Garner & Clement, 1963). In many of these studies, the importance of symmetry has been noted, but not adequately investigated.…”
