During the experiment drew attention to the differences

Fortunately, in our time, we break many stereotypes

Throughout the development of mankind people who are different from the majority of some individual characteristics, for example, left-handers, caused interest and surprise. However, the relation to left-handers often is not limited to such emotions. It was not the same in different countries and at different times, but, as a rule, had any whiff of suspicion and negativism.
In many languages, including all the Indo-European, there is a negative attitude to everything left, including left-handers.
Russian language also provides many examples of this kind. “Left goods” – the goods sold to the left, i.e. illegally, or the goods are fake, tampered with. Similarly, one can consider the meaning of the phrases “income left”, “left money”, “left”, etc. Like the color of the word “left” occurs in expressions that are not related to Finance: “as the left foot wants”, “left side”, “to stand with the left foot”, etc.
In English, the word “left-handed” has the additional meanings “awkward”, “hypocrite”, “evil”, “illegal”. These relationships are examined in French, Italian, Spanish, German languages.
Given the relationship between language and consciousness, it is hardly surprising negative stereotypical perception of the left-handed “right-handed” by the majority.
Fortunately, in our time, when break many of the stereotypes, the concept of “normal” becomes less rigid, changing attitude and various manifestations of individuality. Now the phenomenon of left-handedness much studied, the results of this work allow to change the stereotyping of left-handers and even gradually develop methods of their learning.
Scientists working on the issue of left-handedness, put forward different conceptions of its origin and accordingly speak about the psychological characteristics of left-handers. In my opinion, one thing is certain – you can’t treat lefties as a homogenous group. To implement a differentiated approach to left-handed children are not enough to show to their behaviour and training other than the right requirements. You must consider the various causes of left-handedness, and also to differentiate the concepts “left-handedness” and “left-handedness”.
Left-handedness determines only the dominant hand, whereas left-handedness is a complex trait. In fact, besides the hands for a person to have leading eye, leading leg, driving the ear.
When in school the most important characteristic of the dominant hand, as one of the most difficult activities that are to be acquired by the child, is a letter. Therefore, in future we will talk mainly about the left-handedness, but we can not ignore other kinds of asymmetries, because they can also affect the success of children’s education.
One of the major issues contributing to the approach to left-handers, is the question about the causes of left-handedness. They can be different.
Most often the so-called genetic left-handedness. Until now not known the exact mechanisms of transmission of this indication, but reliably established that left-handedness is 10 – 12 times more common in families in which the left-hander is at least one parent. The genetic left-handers may not be any violations in the development, then it is considered simply individual identity, a variant of normal development.
The second type is a “compensatory” left-handedness associated with any lesion of the brain, most of his left hemisphere. Since the activities of the right hand is mainly regulated by the left hemisphere, in the case of any injury, disease, early child development, the respective functions can take over the right hemisphere. Thus, the left hand is leading, that is more active while performing everyday tasks, and subsequently, most often that of a letter provided for the post by International Adoption research blogger and columnist.
The child with impaired activity of one of the hemispheres of the brain almost certainly will be observed deviations in the development of speech, motor skills, etc. it Should be noted that left-handedness in this case cannot be regarded as the cause of these deviations. They, like left-handedness, are the result of the same reasons.
The third type is a “forced” left-handedness. The choice of the dominant hand in these lefties usually associated with injury of the right hand, but can also be the result of imitation family or friends.
Separately it is necessary to consider pseudolingulate. By a certain age (finally to about 5 years) the child has any of the hemispheres is formed as dominant in relation to the hand (e.g., righties – left hemisphere). But this feature of the brain, both prenatal (or perinatal insufficiency of stem formations of the brain, leads to atypia of mental development, which, in turn, gives form no interhemispheric interaction, no hemisphere specialization. Thus, in children with abnormal mental development is not formed the dominance of the right or left hemispheres in relation to the arm. Then there is pseudoliberalism, or more commonly, a roughly equal use of both hands. The experience of psychological-medical-social centre for the children and adolescents of North-West district of Moscow assures that immature interhemispheric interaction is not directly related to leveltwo. Often, after a few sessions under the guidance of the psychologists, the child begins without any coercion to write and draw with his right hand.
Besides all the above may develop in children the so-called “latent left-handedness”, i.e. a change of the dominant hemisphere. The moment of change is the critical period when the main functions of the Central nervous system is evenly distributed between the two hemispheres, after which it begins to dominate the right hemisphere. Such people can be called “mental” the left-handed or “hidden” left-handed, in the sense that their signs of left-handedness are not associated with left hand dominance.
So, we see that the category of “left-handed” children are not homogeneous and any stereotypes of perception can obscure from us the real child with its completely individual characteristics. This begs the question of the lawfulness and necessity of learning left-handed as such. I believe that the answer to this question is unambiguous: the phenomenon of left-handedness to be studied. However, the complexity of the phenomenon itself makes it researchers high requirements of accuracy and strict scientific experiment, but to people that use data science in practical work with children competency requirements, differentiated approach, pedagogical intuition and respect for “natural selection”.
Currently there are several views on the natural ability of left-handers compared to right-handers.
The first is based on the fact that the indicators of behavior and psychological activity lefties worse than righties. Proponents of this approach cite data on the frequency of left-handedness among patients with epilepsy, mental retardation, schizophrenia, hereditary alcoholism, and the fact that, as adults, these individuals have low adaptive capacity, some “fragility” of mental activity, tendency to transient decompensation.
The second approach affirms the equality of abilities righties and lefties.
Under a third approach, lefties have higher rates of nervous and mental activity and great adaptive abilities than right-handers. This is substantiated by the fact that Lefty’s are constantly having to adjust to the “right-handed” world. As evidence of the correctness of this approach can lead to a whole list of great left-handers, among which are the Roman emperors Tiberius and Julius Caesar, the generals of Alexander the great, Napoleon, J. scientists. K. Maxwell, I. P. Pavlov, artists Leonardo da Vinci, Michelangelo, writer Lewis Carroll, actor Charlie Chaplin, finally, U.S. President William Clinton, and many others.
I think that all three views on the ability of left-handers have a right to exist, moreover, that in fact they correspond to the basic concepts of occurrence of left-handedness and, therefore, do not contradict, but complement each other. Besides negative and positive properties of left-handed people can be two sides of the same coin. For example, there was evidence to suggest that communication between the divisions of the cerebral cortex, in different hemispheres in left-handed compared to right-handers, less rigid. Perhaps this is why lefties and demonstrate, on the one hand, more high creative ability (rigidity strong relationships can contribute to more standard thinking) and slower compared to right-handed skill formation activities requiring interaction of both hemispheres.
In General, left-handers showed a large than right-handers, the heterogeneity of psychophysiological characteristics.
Russian scientists conducted a study of the emotional sphere through the perception of smells. During the experiment drew attention to the differences right-handed, left-handed and Ambidextrous ability to differentiate between pleasant, unpleasant and neutral odors. Left-handed and Ambidextrous most accurately evaluated odors. According to the results of the study concluded: right-handed shown greater sensitivity to emotions positive sign, and for left-handed and Ambidextrous characterized by the predominance of emotions of a negative sign, i.e. they are more pessimistic.
Employees of the University of Michigan has compared the percentage of “handedness” with indicators of temperament in the males and found they have a predominance of indicators such as anger (emotional incontinence), fear (anxiety), low self-control, decreased background mood, conformity ( passive acceptance of the existing order of things), conscientiousness, timidity, aesthetic sensibility, sensuality, an increased level of anxiety.
