Test stimuli designed to test the contribution of the geon intersections to picture recognition.  The four components constituting the original training objects (the watering can, iron, desk lamp, and sailboat) were disconnected so that they no longer touched one another.  The operation of disconnection removed the geon intersections, but left the relations among the geons relatively intact.  The effect of disconnecting geons was assessed with scrambled versions of the objects as well.  If the intersections were important for recognition of the original objects, then the effect of disconnection should be similar to the effect of scrambling object components.
