MONDAY, Jan. 31 (HealthDay News) -- A man is much more likely to
continue dating a girlfriend who cheated on him with another woman
than a girlfriend who had sex with another man, a new study
However, a woman is more likely to stick with a man who had sex
with another woman than a man who had an affair with another
The findings provide new insight into the general male desire to
have a number of sex partners and the general female desire to have
a committed partner, said the researchers at the University of
Texas at Austin.
"A robust jealousy mechanism is activated in men and women by different types of cues -- those that threaten paternity in men and those that threaten abandonment in women," study author Jaime C. Confer, a doctoral candidate in evolutionary psychology, said in a university news release.
The study included 700 college students who were asked to
imagine they were in a committed relationship and how they would
respond to different types of infidelity.
Among men, there was a 50 percent likelihood they would continue
to date a girlfriend who had a lesbian affair, and a 22 percent
likelihood they would stay with a woman who had a heterosexual
Among women, there was a 28 percent likelihood they would keep
dating a boyfriend who had a heterosexual affair, and a 21 percent
likelihood they would stay with a man who had a homosexual
The study was published in the January issue of the journal
Personality and Individual Differences.
