... e game task composed of two types of discriminative stimuli ( predictive and reporting stimuli )and two types of responses ( choice and performing responses ) , After a brief introduction describing game theory for analyzing choice behavior in predictive game tasks as normative theory, we discuss experimental procedures cQrrespQnding to five components of game theory: players , payo 仟matrices , alternatives , moves and strategies , initialconditions , and playing procedures , Based on this discussion , we conclude that thepredictive game task isappropriate for a wide range ofexperimentaI procedures ,
