S regulatory behavior a behavior that tends to bring psychological conditions back to normal, thus restoring the condition of homeostasis e. g. eating, drinking, putting on a warm coat. S: regular system has 4 essential features. S system variable - the variable controlled by a regulatory mechanism. S set point - the optimum value for a system variable. N e. g. the set point for human body temperature is approximately 37oc. S detector - a mechanism that signals when the system variable deviates from its set point. S correctional mechanism - mechanism that is capable of restoring the system variable to the set point.
