3.3 Cognitive Synergy Al — Example of episodic knowledge: memory of the situation in which the agent first met Bob; memory of a situation in which a specific tall blocks tower was built e Attentional memory (knowledge about what to pay attention to in what contexts) — Example of attentional knowledge: When involved with a new person, it’s useful to pay attention to whatever that person looks at e Intentional memory (knowledge about the system’s own goals and subgoals) — Example of intentional knowledge: If my goal is to please some person whom I don’t know that well, then a subgoal may be figuring out what makes that person smile. In Chapter 9 below we present a detailed argument as to how the requirement for a multi- memory underpinning for general intelligence emerges from certain underlying assumptions regarding the measurement of the simplicity of goals and environments. Specifically we argue that each of these memory types corresponds to certain modes of communication, so that intel- ligent agents which have to efficiently handle a sufficient variety of types of communication with other agents, are going to have to handle all these types of memory. These types of communi- cation overlap and are often used together, which implies that the different memories and their associated cognitive processes need to work together. The points made in this section do not rely on that argument regarding the relation of multiple memory types to the environmental situation of multiple communication types. What they do rely on is the assumption that, in the intelligence agent in question, the different components of memory are significantly but not wholly distinct. That is, there are significant “family resemblances” between the memories of a single type, yet there are also thoroughgoing connections between memories of different types. Repeating the above points in a slightly more organized manner and then extending them, the essential idea of cognitive synergy, in the con
