A.2 Glossary of Specialized Terms 331 e Embodied Communication Prior: The class of prior distributions over (goal, environ- ment pairs), that are imposed by placing an intelligent system in an environment where most of its tasks involve controlling a spatially localized body in a complex world, and in- teracting with other intelligent spatially localized bodies. It is hypothesized that many key aspects of human-like intelligence (e.g. the use of different subsystems for different memory types, and cognitive synergy between the dynamics associated with these subsystems) are consequences of this prior assumption. This is related to the Mind-World Correspondence Principle. e Embodiment: Colloquially, in an OpenCog context, this usually means the use of an AI software system to control a spatially localized body in a complex (usually 3D) world. There are also possible “borderline cases” of embodiment, such as a search agent on the Internet. In a sense any AI is embodied, because it occupies some physical system (e.g. computer hardware) and has some way of interfacing with the outside world. e Emergence: A property or pattern in a system is emergent if it arises via the combination of other system components or aspects, in such a way that its details would be very difficult (not necessarily impossible in principle) to predict from these other system components or aspects. e Emotion: Emotions are system-wide responses to the system’s current and predicted state. Dorner’s Psi theory of emotion contains explanations of many human emotions in terms of underlying dynamics and motivations, and most of these explanations make sense in a CogPrime context, due to CogPrime’s use of OpenPsi (modeled on Psi) for motivation and action selection. e Episodic Knowledge: Knowledge about episodes in an agent’s life-history, or the life- history of other agents. CogPrime includes a special dimensional embedding space only for episodic knowledge, easing organization and recall. e Evolu
