Pain facial expression: Individual variability undermines the specific adaptationist account

  • Christine R. Harris (a1) and Nancy Alvarado (a1)

Abstract

The proposal that there are specific adaptations for the expression and detection of pain appears premature on both conceptual and empirical grounds. We discuss criteria for the validation of a pain facial expression. We also describe recent findings from our lab on coping styles and pain expression, which illustrate the importance of considering individual differences when proposing evolutionary explanations.
