 Richardson and Benzon both align themselves with cognitive science and distinguish that alignment from one with evolutionary psychology.Flesch makes use of evolutionary research on game theory, costly signaling, and altruistic punishment but, like Stephen Jay Gould, professes himself hostile to evolutionary psychology.For a commentary that is sympathetic to evolutionary psychology but skeptical about the possibilities of using it for literary study, see Steven Pinker, "Toward a Consilient Study of Literature," a review of "The Literary Animal", "Philosophy and Literature" 31 (2007)
