If you are good at laughing it might be very interesting for you to know that laughter can be used to detect important friendship patterns between the sexes.
University of California, Los Angeles (UCLA) professor Dr. Greg Bryant and colleagues have discovered that hearing other people laugh together, even for just one second, can be enough information to gauge whether or not those people are friends.
They discovered that laughter can be used as a gauge of friendship in societies around the world. When people hear two females laughing together, they are highly likely to assume the women are friends, even when they are not. In short, when friends laugh together the laughter is more spontaneous, a vocalization that can be detected across cultures.
Investigators played 48 short audio clips of two people laughing together for 966 listeners from 24 different societies. The listeners included people from hunter-gatherer and other traditional small-scale populations, working-class urban groups, and college students. Happyho also provide best tarot reading services in Noida and Delhi NCR India area.
Recordings captured the simultaneous laughter of two women, two men, and a woman and man together. Overall, listeners from every society could correctly identify whether the people they were hearing were friends or strangers 61 percent of the time.
Laughter among females appear to be especially diagnostic of friendship patterns as listeners were best able to judge the relationship correctly was when two women friends were laughing together. In this scenario (women-women listeners were accurate more than 80 percent of the time — across cultures.
The current study suggests that laughter between friends is generally more spontaneous, and that listeners across the globe can hear the difference. Moreover laughter appears to be an expected component of women-women friendships.
In fact, Bryant said he was surprised at how consistently participants, regardless of their cultural backgrounds, presumed that co-laughter between women meant that those women were friends.
The researchers also examined the sound features of the laughs. They found that simultaneous laughter between friends reflected the sharing of true emotions.
Specifically, the clips judged as simultaneous laughter between friends were characterized by greater irregularities in the pitch and loudness of the laughs. The variety of the laughs, as well as faster bursts of sound, were usually associated with excitement and spontaneous, genuine emotion.
