Adquisición de la primera y segunda lengua en aprendientes en edad infantil y adulta.

With the aim of applying useful and beneficial techniques in foreign language teaching, it is important to understand the inner processes of language acquisition, initially in our mother tongue, so as to analyze the same processes in second language acquisition. We will bear in mind not only the similarities but also the differences in both cases, since we believe that we may apply fruitful methods and strategies of the acquisition of the L1 into the learning of the L2. On the contrary, it is also essential to take into account circumstantial differences between the natural acquisition of our language as native speakers, and those circumstances of second language learners. Those factors are intimately related to age, if the learner acquires the language in question in their infancy or at adulthood, if the language is learned in a meaningful context as is their natural social environment, or if it is learned in the classroom with its corresponding limitations, etc. We will study the advantages that offer a teaching context for those students whose only opportunity to use the language is the classroom, despite the prospective obstacles implied in a non-native environment
