In this lesson we have discussed above the relationship between:
BRAIN AND LANGUAGE
this report are based on many empirical studies on the reflection of the language.
One of the many scholars who propose such studies is PAUL BROC '. He discovered in 1861 and is dedicated to a specific area of \u200b\u200bthe brain, which, thanks to his discoveries he was also named.
AREAS BROC 'is the area of \u200b\u200bthe brain that governs the production of speech sounds and is located in the left frontal lobe of the brain. If you have a physical damage in the Broc, s'incorre in a language with no dysfunction in the production of sound and then it was silent in the face of a subject. This is known as aphasia.
You can also speak of aphasia engines, when a person has an inability to move the muscles that allow the production of verbal sounds.
The human brain has evolved very slowly, or about two million years.
In fact, two million years ago apes appear on earth.
The transition from apes to hominids has the appearance of Homo ABILIS , and then with LUCY , the first hominid found in Ethiopia. This transition occurs with the descent of the monkeys from the trees. This event also produces the largest increase in the history of brain size. In fact, the brain doubles
australopithecines, brain of 600 cm ³;
homo habilis , the brains of 900 cm ³. Homo habilis
specializes is giving rise to the HOME ERECTUS , where we experienced an increase in brain mass by 25%. Homo erectus have the appearance of skill of hunting and building shelters. This leaves room for the HOME
SAPIENT . The most famous example among homo Sapient is the man of Neanderthal . Their step is the first to have had a religion. In practice this religion, though primitive, they used to practice: burial rites, cannibalism, etc..
The net difference between the man of Neanthertal and his successor is that he did not speak. In fact, Homo Sapient , although quite advanced, with the pharynx and a brain equal to those who have succeeded, failed to deliver speech sounds. The presence of the word no was not, then due to a cognitive problem, but a problem of biological origin. The HOMO SAPIENT
SAPIENT , in fact, develop that trait that allows the use of the word and that is the treatment SOPRALARINGEO .
As the deaf, the Neanderthal man, develop a visual language - gestures that allows him to communicate even without words.
We also touched on the theme of children WOLF.
These are children who are raised in a community of speakers, abandoned in an environment devoid of civilization, may regress to the status of great apes. Many of these children do not develop as well as the word does not even develop a standing position.
