Compared with evolutionary psychology, a unique aspect of the stimulus-value-role (SVR) theory is that
1. Only SVR theory is concerned with visible properties of potential dates.
2. SVR theory is more concerned with stages of development, arguing that the critical factors that foster attraction differ according to the relationship’s evolution.
3. Only SVR theory is concerned with mate selection.
4. SVR theory focuses more on how value preferences in mate selection differ among men and women.
