  We analyze the pedestrian evacuation of a rectangular room with a single door
considering a Lattice Gas scheme with the addition of behavioral aspects of the
pedestrians. The movement of the individuals is based on random and rational
choices and is affected by conflicts between two or more agents that want to
advance to the same position. Such conflicts are solved according to certain
rules closely related to the concept of strategies in Game Theory, cooperation
and defection. We consider game rules analogous to those from the Prisoner's
Dilemma and Stag Hunt games, with payoffs associated to the probabilities of
the individuals to advance to the selected site. We find that, even when
defecting is the rational choice for any agent, under certain conditions,
cooperators can take advantage from mutual cooperation and leave the room more
rapidly than defectors.
