Figure 2: Grid system quadrant, and I6 indicating the presence of that drawing/colour in all I6 What we wished to analyse was not simply whether a particular picture(or colour)was merely present in the theoretically correct quadrant, but also the degree to which it did not appear in the theoretically incorrect quadrants. It would be meaningless if some proportion of a drawing appeared in the theor- etically correct quadrant, if that same drawing also overlapped to a large legree with other, theoretically incorrect quadrants. Therefore, difference scores were computed that represented the relative proportion of a drawing/colour in the theoretically correct quadrant to that which appeared in the incorrect quadrants. Therefore, eight difference scores were computed. First, there were four difference scores associated with each quadrant, which were given these names: Father Quadrant Difference(FaQD), Unconscious Quadrant Difference (UnQD), Mother QuadrantDifference (MoQD), and Future QuadrantDifference(FuQD). These variables reflect the proportion of the associated drawing/colour present in its quadrant, as compared to the other three drawings/colours in the quadrant (within-quadrant analysis According to the Jungian schema, a drawing/colour associated with a quad rant should appear most in that quadrant. To find these values, the differences etween the associated drawing/colour for a given quadrant and the other three drawings/colours were determined. This produced three differences which were summed, producing a value that can be between +I6 and -I6; posi- tive values indicate an overall higher proportion of an associated drawing/colour n a particular quadrant compared to the other drawings/colours, while nega tive values indicate a higher proportion of the unassociated drawings/colours that quadrant. A score close to o would indicate no particular dominance of90 Derek P. Bergeron et al. quadrant, and 16 indicating the presence of that drawing/colour in all 16 grid boxes in that quadrant.
