A study led by Jillian O’Connor, a graduate student in the Department of Psychology, Neuroscience & Behaviour at McMaster University, found that people think they can predict whether a mate will cheat by listening to tone of voice.
And, they may be right.
According to the McMaster news release,
“The reason voice pitch influences perceptions of cheating is likely due to the relationship between pitch, hormones and infidelity,” explains David Feinberg, an assistant professor in the Department of Psychology, Neuroscience & Behaviour and advisor on the study.
“Men with higher testosterone levels have lower pitched voices, and women with higher estrogen levels have higher pitched voices. High levels of these hormones are associated with adulterous behaviour and our findings indicate individuals are somewhat aware of the link and may use this in their search for a romantic partner.”
