Document Summary
Assessor prior information (instinctive, shaped through natural selection, priory learned) Signaler has cues and previously known facts about conditions. Condition could be external to assessor or signaler (predator, availability to food) or could be internal to signal (receptively mating, offspring signaling its hunger to parent, could be about its own condition) Could make a decision based on prior information, but after cues and signals it makes a better decision. Effect back on receiver, effect back to signaler (could reverse roles) This system has two individuals engaged in an interaction, there is an effect for both in the interaction. Ultimate payoff for both should be positive (natural selection should favour when both outcomes are positive) Could have one benefit and the other individual not have any out come (not bad or good) All engaged in a one on one interaction: By passing up something (perfectly good meal) the signaler (prey) benefits and the receiver (predator) gets nothing = deception.
