Women define the reliability of a man's voice, namely the change in his voice. These data are published the research team from McMaster University.
In the present experiment took part 87 of women volunteers who listened to the voices of different men and tried to define them in reliable people or izmenshchikov. More women preferred men with a low voice, but more often noticed in such votes "notes treason". Women admitted that they would not build a serious relationship with them.
Scholars argue that the process of understanding the essence of the person through his voice emerged in women in the process of evolution and is a complex mechanism of recognition of voice timbres and tones. It is worth noting studies conducted previously. It turns out that the voice of a man can change if he communicates with an attractive member of the opposite sex.
