In this paper, we propose a new solution concept, called interperceptional
equilibrium, in games with interperception. Two sufficient conditions for a
n outcome to be an interperceptional equilibrium are given. It is also show
n that, under some realistic conditions, the concept of interperceptional e
quilibrium can be regarded as a generalization of the concept of Nash equil
ibrium. The relations between the framework given in this paper and those o
f "soft" game theory and drama theory are also discussed.
