berlyne (i97i, pp. 28-29) acknowledged that "reactions to artificially simple sights and sounds are admittedly a long way from appreciation of art." however, a concern regarding the use of art is an absence of control over the determinants of the subjects* preferences. this research attempted to overcome these methodological problems through the use of artistic pictures with the variation of a single stimulus within each picture, and consisted of two experiments, with university 世界杯2022赛程表淘汰赛 as subjects. experiment 1 determined aesthetic preferences for size and location of the moon. forty redrawn photocopies of "moose at night (moonlight)** of tom thomson, were put on slides and used for eliciting aesthetic preferences. the moon was varied on each slide, with 5 different elevations and 8 different sizes.
