You can know the height and strength of a person by hearing them scream

To demonstrate this, psychologist Jordan Raine of the University of Sussex (UK) and his colleagues conducted an experiment by recording the screams of actors at a London film school. 'We used to run a pilot test before and found that most ordinary people cannot shout comfortably. But the actors do it very well , 'Raine said.

At the beginning of the experiment, the team asked 31 men and 30 women to imagine they were engaged in a fight, then they would growl like they were ready to fight and shout out something like 'Nhieu that's enough, dive !!! '. All developments will be recorded. At the same time, participants also measured height and strength by testing traction through special tools.

Men are more sensitive than women in determining height through voice.

The next step, the scientists brought the recordings to other volunteers and asked them to make predictions about whether the owner of the voice was tall or short, and stronger or weaker than themselves. The results showed that in 88% of the trials, men who listened to the screams could accurately predict these figures. Meanwhile, this rate in women is 77%.

Data obtained after tests show that men tend to underestimate the power of women through their screams, while women are the opposite, they often value strength. of man than reality. However, if compared, men are more sensitive than women in determining height through voice . In general, height has no relation to strength, but they are all associated with screams.

According to the researchers, the reason women are worse when predicting height may stem from belief in the fact that the average height of men is always higher than women. However, the research results also partly show that body size does not seem to be the first choice when men choose partners but strength.
