In a previous post, I wrote about how men and women are differentially jealous to sexual versus emotional infidelity of their romantic partners (men and women are more concerned about sexual infidelity and emotional infidelity respectively). On a related note, I’ve also written about how people glean individuals’ likelihood of committing an actual or ascribed infidelity as a function of their faces or voice pitches. In today’s post, I’d like to add to the infidelity theme by describing a 2014 article coauthored by John E. Edlund and Brad J. Sagarin and published in Personality and Individual Differences in which they achieved two key objectives: 1) Devised a new four-item measure to capture an individual’s mate value (studies 1 and 2); 2) Examined how mate value moderates individuals’ responses to sexual versus emotional infidelity (study 3). For the purposes of today’s article, I shall focus on study 3. The authors theorized that individuals’ possessing higher mate value scores would be more pronounced in the sex-specificity of their responses to sexual versus emotional infidelity.
