The other side of the coin: Intersexual selection and the expression of emotions to signal youth or maturity
Published online by Cambridge University Press: 14 October 2009
Abstract
Vigil summarizes sex-related differences in emotivity, and presents a psychological model based on the restrictive assumption that responses to stimuli are dichotomous. The model uses for support the concept of intrasexual selection, but ignores intersexual selection. An alternative hypothesis might be that emotivity signals age: maturity in men and youth in women. Integration requires considering all evolutionary biology, not just agreeable concepts.
