What Does right-handed Mean
Diestro is a term originating from the Latin word dexter and used, as an adjective , in reference to who is right (that is, who has a natural tendency to use the right side of his body ).
The person who usually uses the right hand or the right leg , therefore, is right-handed. On the contrary, the person who most frequently uses the left hand or the left leg is known as a left-handed person .
For example: "The team has many right-handed players and few left-handed players" , "She is a right-handed tennis player with great service and speed to reach the net" , "My mother is right-handed, but I'm left-handed" , "If you want to play for this part of the field, you will have to put aside your right-handed tendency and learn to use both legs ” .
The right-hander is more skilled with the right hand. Therefore, he will write, take a scissors, and do other activities with this hand. The opposite will be done by the left-handed person, who will use his left hand more frequently. Those who handle both hands with equal skill are called ambidextrous .
The adjective skilled also applies to those who are skilled or skilled in a trade : “He is a skilled man in negotiating with clients” , “The teacher told me that I am skilled in crafts and suggested that I take art classes to perfect my technical " , " I do not think it is appropriate to hire this professional: we need someone skilled in managing employees . "
Finally, dextrous is someone shrewd who does not stop in the face of difficulties or who is benign and fortunate .
Laterality
Laterality can be defined as the consequence of the distribution in our two cerebral hemispheres of the different functions , which depends on whether we prefer to use one or the other side of the body to carry out certain actions and to react to certain stimuli.
It is a complex function that is related to the binary nature of our nervous system ; In general, our body is organized in pairs: two lungs, two eyes, two ears, two ears, two kidneys, and so on. In the same way, our brain has at its disposal two specialized hemispheres that are in charge of the control of this dual system to allow us to move efficiently through the world around us and communicate with other living beings.
As mentioned above, a person can be right-handed or left-handed, although there are more possibilities, which are grouped within the crossed or mixed laterality . This concept assumes a non-homogeneous lateral predominance, and the possible combinations are several, although the most frequent consists of the predominance of the right hand and foot together with the left eye, a case that occurs in more than 30% of the population. , mainly in women, and supposes a greater cerebral symmetry .
Some people believe that being right- or left-handed is related to their cognitive abilities and their personality; Similarly, there are those who think that cross laterality has a certain impact on these aspects, although science has ruled out on more than one occasion a significant influence from the type of laterality.
The crossed laterality usually appears in cases of dyslexia, although it is not its sole and essential cause, it brings complications in the perceptual-motor organization, negatively affects spatial organization and causes reading disorders. On the other hand, some experts point out that it can be a symptom of learning difficulties.
There are treatments to alter laterality, and in some cases it is believed that they may offer emotional benefits, since certain specialists attribute some social disorders to crossed laterality. However, many doctors recommend avoiding such treatments and focusing on resolving psychological problems through therapy .
