The work looks for phenomena related to the development of spatial imagination. In theoretical part, we define spatial imagination and the aim for finding factors which influence its development, e.g. schooling, sex, laterality or the role of senses. Research investigation forms the practical part of the paper. In the individual investigations, we search for the relation between spatial imagination and general intelligence, between spatial imagination and imagination in plane. By means of the Top-view or bottom-view test, we search for the answer to the question how spatial imagination relates to laterality. Based on the findings obtained in the research investigations, we developed the worksheet Wire and cube that was checked during the class work at an elementary school. The benefit of the paper for the development of the scientific branch and pedagogical practice is the study of phenomena related to the performance and the results of the spatial imagination tests that can be influenced by these phenomena.
