D. E. Berlyne (1960, 1974) posited an increasing linear-function for c
omplexity with an inverted U-shaped function for pleasure. Berlyne's t
heory of aesthetic response was tested through the presentation of 6 c
olor reproductions of paintings to 92 participants and the gauging of
their responses. When participants' pleasure was compared with interes
t, that hypothesis was upheld. However, when complexity was compared w
ith pleasure, Berlyne's theory was not supported.
