9.6 Body and Mind 171 4, Recognition of emotions in other agents via their physical embodiment 5. Recognition of desires and intentions in other agents via their physical embodiment 6. Analogical and contextual inferences between self and other, regarding BDI and other as- pects 7. Attribute causes and meanings to other agents behaviors 8. Anthropomorphize non-human, including inanimate objects The main special requirement placed on an AGI’s embodiment by the above aspects pertains to the ability of agents to express their emotions and intentions to each other. Humans do this via facial expressions, gestures and language. 9.5.1 Motivation, Requiredness, Value Relatedly to folk psychology, Gestalt [Koh38] and ecological [Gib77, Gib79] psychology suggest that humans perceive the world substantially in terms of the affordances it provides them for goal-directed action. This suggests that, to support human-like intelligence, an AGI must be capable of: 1. Perception of entities in the world as differentially associated with goal-relevant value 2. Perception of entities in the world in terms of the potential actions they afford the agent, or other agents The key point is that entities in the world need to provide a wide variety of ways for agents to interact with them, enabling richly complex perception of affordances. 9.6 Body and Mind The above discussion has focused on the world external to the body of the AGI agent embodied and embedded in the world, but the issue of the AGI’s body also merits consideration. There seems little doubt that a human’s intelligence is highly conditioned by the particularities of the human body. 9.6.1 The Human Sensorium Here the requirements seem fairly simple: while surely not strictly necessary, it would certainly be preferable to provide an AGI with fairly rich analogues of the human senses of touch, sight, sound, kinesthesia, taste and smell. Each of these senses provides different sorts of cognitive stimulation to the human
