Since I moved to Germany one of my hobby horses is being multilingualism. Many people have realized the mistakes I make in my own native language and although I could not secure with absolute certainty whether I have noticed that in recent years, the more often I have spoken in another language I found it harder to "come home." Now I find to fight with three in those days when mental capacity is not enough for most are too juggle. And so today I want to talk about the science behind language learning.
There are two theories about the origin of language: the biological theory of Chomsky (1959) and learning Skinner (1957). However, studies of phonetic perception in infants one year showed how cognitive, social computing and combine to give rise to language learning not look like the model of learning by operant conditioning and reinforcement of Skinner or the comprehensive overview of Chomsky's parametric settings. In other words, the discussion remains open and in some forums, bitter ( Child's Play )
Language learning is one that could be considered classic examples of what is called critical period in neurobiology (also described for the development of senses such as vision, for example) and that in this case means that there a period in which learning ability is high and once overcome learning new languages \u200b\u200bis much more complicated. That's why children and even babies are much more able to learn languages \u200b\u200bthan adults, despite the higher cognitive development of the latter. Grrr y. .. if only a language! What do you think of the rage that these dwarfs are not two feet from the ground up on the ski slopes with snot hanging out and give you not one but many turns you almost do not know how to put your feet in line ... C 'est la vie.
There are several hypotheses about the causes of this temporal limitation on the learning of new languages \u200b\u200bin adulthood. In the 60 Lennenberg suggested that the growth of the corpus callosum was responsible for this impairment. More recently, Newport has proposed the hypothesis of "less is more" for which the limited intellectual capacities of children would learn better babies simplified language that they speak (1990), Patricia Kuhl proposed the concept of neural commitment by which the architecture and neural circuits for infant / child are developed to maximize the efficiency of language processing to which the child is exposed, and once established, this architecture will impede the learning of those patterns that do not conform to the known and this is where you enter all the other languages. Experiments in this laboratory have shown that as early as 9 months of age can learn a foreign language for the first time (2003 Kuhl ) and the presence of human beings, the real contact improved learning. The importance of social interaction in learning / language development may be due among other reasons, increasing attention and interest, such as interaction with parents and guardians directed infants' attention to the figures and images that were related to adding new vocabulary contextual information and thus facilitate learning. So, as much as Home Inglés sell us the wonder of its methods of language learning is most effective real interaction, to live the language, creating a social context that increase the interest and facilitate recall by association, so please to work and take it get yourself a foreigner gives canes, the kind of language is most effective (but not cheap) you can get.
But what differences between the brains of bilingual people and those who are beginning to learn a new language? Can be followed by looking at the role brain structures and progress in mastering a new language? The answer is yes.
Since the late 90's knows that there are differences in activation patterns depending on the age at which you learn the second language, bilingual PET or fMRI studies show a strong left hemisphere activation for the native language that overlap in activation patterns of the second language, but when the second language is learned later the neural circuits used for the second language differ from those of the native tend to be less lateralized and vary between individuals (for a summary of all areas involved in learning the different forms of language, I recommend reading the work of Neville et al ). Likewise, it has been shown that in the beginning when you do not have much control over the second language (especially in semantics and syntax, or grammar), there is a high activity in the cortex prefontal, especially in the areas of language and less activation in temporal region (1). these differences tend to disappear as you increase the domain of the second language. As regards structural changes, the work of Stein et al (2010) studied the structural changes that 5-month learning German students whose native language was English and showed a correlation between structural changes in gray matter (mainly composed of neuronal cell bodies or bodies / glial) of left inferior frontal gyrus (where Broca's area) and increased competition in the second language. However, in absolute terms in the second language competence and the gain of gray matter are not correlated, meaning that learning occurs a reorganization, but the relationship between these two events is not direct, we can not that gray matter how much you earn more about bilingualism are. Remember buddies and repeat after me: "Correlation does not imply causality."
In a final twist an article appeared this year offers the possibility to predict the ability of parendizaje a second language based on the activity of the caudate-spindle circuit in the left hemisphere for what they studied a group of Chinese children of 10 years who had begun to study English as a second language at 6, they were put in a scanner (fMRI) and measured the changes that occurred in their reading skills and understanding in a year. They found a correlation between activity in these areas and also reading ability was specific to the second language thus concluding that it is possible to use these measures as a proxy for learning ability. However, Chinese is a symbolic language used to read different brain areas is therefore expected that the integration path for English is independent of the Chinese. So do not run yet the scanner because it will not give the answer the million: Will I be able to deal with English / German / francés...o it's time to surrender?

I though decreasing curve damn I continue to rely on brain plasticity in these meetings tandem: beer + conversation = guirilike in no time.
