Development of a Japanese Version of the Object-Spatial Imagery Questionnaire (J-OSIQ)

Abstract

The Object-Spatial Imagery Questionnaire (OSIQ) is a measure of individual differences in visual imagery preferences. In the present study, we attempted to develop a Japanese version of the OSIQ (J-OSIQ). On the basis of principal components analysis, we obtained two factors in the questionnaire. An object imagery scale (15 items) assesses preferences for representing colorful, pictorial, high-resolution images of individual objects or scenes. A spatial imagery scale (15 items) assesses preferences for representing schematic images of objects and spatial locations of objects. The reliabilities of these factors were similar to those of the original version. Additionally, we showed that the object imagery scale was selectively correlated with object imagery measures, whereas the spatial imagery scale was selectively correlated with spatial imagery tests. These results demonstrate that the J-OSIQ is useful for measuring preferences for object and spatial imagery in Japanese.
