Maps.
Women showed closer relationships in their maps (sociograms). Most of their objects were placed lying down except those objects off the frame of the map. They placed themselves close to their twin brother but turned from him.

Men showed one intense relationship to the exclusion or avoidance of others. Twin sister was portrayed either as a little object or baby behind them. Most objects were erect. There was some object between the twins in all maps.

Paintings
