How _multifinality_ is used here ## The idea in one line**Multifinality** names the situation where the same signal can carry different meanings depending on the person and the context. In this channel's material on emotion-aware AI, it matters because a model that reads emotion from voice and face cannot treat an expression as a one-to-one code — the same vocal pattern or facial movement can correspond to different underlying experiences for different people. That is why the conversation with Alan Cowen emphasizes how the model handles individual differences rather than assuming a single universal mapping.
