The Evolution & Relationships at Oklahoma State (EROS) Lab

Romantic relationships are among some of the most impactful social relationships we have during our lifetimes. The EROS lab aims to advance theory and generate novel insights into three broad relationship problems that people face when seeking or in a relationship:





To this end, we utilize an interdisciplinary approach that integrates theories and knowledge from classic social psychology and relationship science (e.g., attachment theory, interdependence theory), evolutionary biology and psychology (e.g., sexual selection, theories of adaptive calibration, error management theory) to examine evolved psychological and biobehavioral mechanisms that underlie attraction, relationship behaviors, long-term satisfaction, relationship dissolution, and intrasexual competition. Additionally, we often employ an evolutionary mismatch perspective to consider how such evolved mechanisms may be disrupted or altered by evolutionarily novel features of the modern environment (e.g., hormonal contraceptives, availability of alternatives, etc.). 

How to get involved:


How do people choose relationship partners?


How do people maintain
long-term pair bonds?


How do people navigate relationship threats such as intrasexual rivals?
