Scanator is an extremely valuable tool in the functional analysis of qualitative stability in text building behavior during writing. Scanator also allows for a detailed investigation of subtle changes emerging in the structural relations of emergent novelties. This study focused on the extension of the application of Scanator to one pair of dizygotic (DZ) twins. Specifically, the study examined whether DZ twins differ in their mental structures as they construct text. The test material consisted of a series of pictures in which a baby is navigating a visual cliff--a sheet of glass between the child and its mother. Subjects wrote a 5-page essay in Swedish, rewrote the essay, constructed an abstract of the essay, then wrote the essay in English. The Scanator results did not indicate any systematic differences. A powerful effect was found in the cohesion of the produced verbal flows, but no such effect was evident in the elasticity of text volume flows. Contains 13 references. (Author/MDK)
