Want to be more memorable with the ladies? If your looks aren't that stellar, then having a deep voice might just work, according to a new study.
Psychologists had recorded the voices of men and women saying the names of a variety of different objects. The voices were then manipulated to either sound lower or higher.
A group of straight women were then recruited to look at pictures of the objects while listening to the voices. During a recognition test wherein the women were shown two similar versions of an object and asked to indicate which version they'd seen previously, they found that hearing artificially lowered male voices naming the objects helped them in recalling the right pictures. The women also reported that they found the lowered male voices more attractive, while lowering the pitch of female voices had no effect.
The study authors conclude that the results "indicate for the first time, so far as we are aware, that signals from the opposite sex important for mate choice affect the accuracy of women's memory." They also believe that having low voice is one cue for masculinity:
[B]ecause of the double-edged quality of male masculinity, it might be beneficial for women to treat information about the past behaviour of conspicuously masculine individuals as a decisive factor when judging whether or not they wish to have a relationship. Most notably, perhaps, the ability to recall details associated with particular masculine individuals may lead mate choice either towards or, indeed, away from that individual, depending on what exactly is remembered.
