Can learning to simulate group conversations make robots behave more like humans? What could the behavior of robot mean..I think in one case it is how the robot interfaces with human (hmm..this an exciting new question of Human computer interface..)..Well one can design new interfaces to control robots in new ways..(like data gloves to control snake robots)..but this question can also be posed in the reverse manner (subject and object interchanged in the question just like camera being an opposite to a projector in an input output system metaphor..).
