In this paper three experiments, concerning an individuals per-ception of components in the environmental setting, are referred. High correlations between an individuals description of the num-ber of components in an environment and the semantic Complexity has been found. The number of components described as not fitting in showed highest correlation with semantic Unity, but also cor-relations with Pleasantness and Complexity seemsto exist. Compo-nents not fitting into an environment have different effect on the individuals description on Complexity and Unity, depending on whether the component is of a permanent or temporary character. The experiments are based on judgements of architecture and high school students for a number of color slides of urban and rural landscape environments.
