The inner eye theory of laughter: Mindreader signals cooperator value

From the book : Evolutionary Psychology 1: 214-253.
In this hypothesis paper, I propose  a three-component set of jointly necessary and sufficient trigger criteria for all cases of involuntary laughter.
 The theory incorporates concepts from the theory of mind in cognitive science.
 I then examine the information content of the laughter signal from a game theoretic perspective.
 I conclude that laughter is a signal of cooperator value as it provides information on the laugher’s empathy with  the attributed mental states and her sympathy levels for all affected by the laugh-inducing situation.
 Laughter also indicates what types of mental representations children, autistic people, nonhuman primates and adults possess and can falsify.
