Human beings have evolved a rich and sophisticated set of processes for engaging with the world in which cognition and affect play two different but equal roles. Both cognition and affect can be thought of as systems for information processing. One, that of cognition, interprets and makes sense of the world. The other, affect, evaluates and judges. The affective system modulates the operating parameters of cognition and provides warning of possible dangers, thereby enhancing survivability and reliability. The study of how these two systems work together provides guidance for the design of complex autonomous systems that must deal with a variety tasks in a dynamic and often unpredictable environment.
