• "Homospatial thinking" consists of actively conceiving two or more discrete entities occupying the same space, a conception leading to the articulation of new identities. Homospatial thinking has a salient role in the creative process in the following wide variety of fields: literature, the visual arts, music, science, and mathematics. This cognitive factor, along with "Janusian thinking," clarifies the nature of creative thinking as a highly adaptive and primarily nonregressive form of functioning.
