Responses to Scenes with Spreading, Rounded, and Conical Tree Forms

Research has shown that people typically give high aesthetic preference ratings to trees with spreading canopies, similar to those found on the African savanna. If the savanna hypothesis is correct, people likely will have strong emotional responses to such trees as well. In this study, preferences & emotional responses of 206 participants to viewing scenes with different tree forms & urban elements were examined. Slide images of spreading, rounded, or columnar trees, or inanimate objects in two urban scenes were created. As expected, participants found scenes with trees more attractive than scenes with inanimate objects, & they rated spreading trees more attractive than rounded or columnar trees. Participants reported more positive emotions when viewing trees compared to inanimate objects, & they were happier when viewing spreading trees compared with other tree forms. These results are consistent with the savanna hypothesis, with emotional responses relating to preferences for trees with spreading forms. Tables, Figures, References.
