This study is one outgrowth of a program of research devoted to an analysis of perception from an organismic point of view. This view, the sensory-tonic field theory,3 has interpreted perception as a function of "organismic-state: stimulus-object" relationships and, accordingly, has systematically integrated facts which show the effects of changes in organismic state on perception. Though a wide variety of conditions affecting organismic state and a number of dimensions of perception have been investigated, of particular pertinence to the present study are the two experiments which follow.
These experiments were based on the assumption that some changes in organismic state possess vectoral qualities which may be expected to have bearing on space perception. For example, the experiences of success and failure seem to be related to "upwardness" and "downwardness," respectively, and one could reasonably expect that the organismic correlates of these experiences would be reflected in changes in perception
