Laughter is not a thing of jokes

According to scientists, the way to laugh also depends on the sex of the person: men emit more ufas and tongs, while the female laughter is more singer. However, the tone used when laughing is much higher than that of speech.

Researchers have measured the fundamental frequency and have found that the frequency of female laughter is twice that of speech, approximately 2000 Hz. In the case of men, although the tone of speech is lower than that of women, the frequency of their laughter is 2.5 more and reaches 1000 Hz.

Besides the acoustic measurements, in the environment of the laughter there are many unresolved aspects. For example, you can reach the laughter with very different agents, which provokes a debate on the origin of laughter. What is laughter? Mechanical or physiological response when exciting certain nerves? Or the result of a psychological activity that generates internal emotions?

Tickling can be taken seriously

Kilimak is a clear example of the theory of mechanical response. Although it seems the opposite, tickling should be taken seriously, as it is not easily understood that while some laugh they are unsustainable for others. They can be so unpleasant that in the Middle Ages they used torture as a method. At the other end, however, is the image of the father who makes the child pledge to laugh.

The desire of men and women are very different.

Aristotle seemed a rather deep and serious subject and reflected on them. The famous philosopher realized that the tickling is more effective when done by chance, that is why it is so difficult for everyone to become tickling. Centuries later, Bacon and Darwin also wrote on this subject and the XIX. In the twentieth century, psychologists made the classification of tickling. Recently, a researcher at the University of California noted that the part of the body most sensitive to tickling is the armpit. The waist, ribs, feet and knees are followed, respectively.

Several psychologists affirm that Kilim has great importance in evolution. Apparently, the body parts that appear during the struggle are at the same time the most sensitive to tickling. As a result, through the protective movements they carry out when lifting the tickling, the children prepare for the struggle.

Other studies try to clarify the psychological aspect of laughter. It has always been believed that in the same situation one laughs more if one is in the proper environment. Somehow, before it is "heated" or prepared and the same joke makes more grace than in neutral environment. Therefore, with a desire for joke, it was thought that the reaction with the crickets would also be greater. However, a recent study has shown that warming does not influence reaction to kilometer. To this conclusion, at least, the authors of the study have arrived. In their experiment they used two groups of students: a group was made to watch comic films before making the tickling, but they did no more grace than others.

Few jokes with neurons!

Absurd situations and games give laughter.

One of the aspects that most surprises the researchers is that there is the same response from agents as diverse as hearing a joke or a humorous joke, stumbling with the collateral, being exposed, raising crickets, etc.

There are many theories that explain what causes laughter, of which four are the best known: the theory of superiority (taught by Hobbes), that of incongruence (Kant and Schopenhauer), that of catharsis (Freud) and that of the game (Mulkay). According to the first, situations that put someone above the neighbor make to laugh, for example, when the side puts the leg. On the other hand, the theory of incongruity gives us laughter from the absurd and the contradictory. The theory of catharsis says it serves to release the stresses accumulated by laughter; and that the game provokes anything if you take the laughter in joke.

Absurd situations and games give laughter.

At present these theories are considered as partial explanations. Therefore, in order to unravel the mystery of laughter, many scientists have resorted to the nucleus and investigated the activity of the brain. According to some researchers at the University of California, the zone of humor control is in the ascending frontal circumvolution of the brain. To demonstrate this, a 16-year-old girl was excited about this field: when the stimulus was soft, the girl smiles, and when the intensity of the stimulus increased she became laughter. They have studied the hormones that flow in many other studies, the relationships between neurons and chemicals that are released, but many aspects are yet to be resolved.

Anyway, although we do not know how or why, it is safe to laugh is beneficial; it is more, according to some doctors, a cheap and effective method to fight diseases. So if you have spent more than a hundred years of healthy and cheerful life, laugh the guts until you explode
