Is there a sensitive period in second language learning?

Seminar paper from the year 2011 in the subject English Language and Literature Studies - Linguistics grade: 10 University of Erfurt (Philosophische Fakultät - Fachbereich Anglistik) course: Second Language Acquisition language: English abstract: 'A tree must be bent while it is young.' (Proverb)Proverbs usually have an element of truth. The German speakers will certainly also know the German equivalent 'Was Hänschen nicht lernt lernt Hans nimmermehr.' Do these proverbs also apply to the acquisition of a second language? Are young learners trees that 'must be bent' before they are too old to reach a certain language proficiency? In first and second language research the concept of a 'critical period' respectively of a 'sensitive period' was developed to explain probable advantages of children in the process of language acquisition. The aim of this term paper is to find out whether there is a sensitive period for second language learning and to explore possible explanatory approaches.Within this research the 'Critical Period Hypothesis' (CPH) represents the major focus. According to this hypothesis there is a period during which language acquisition is easy and complete (i.e. native-speaker ability is achieved) and beyond which it is difficult and typically incomplete (ELLIS 1997: 67). This means it is assumed that language learners must begin at an early age to learn a language in order to reach native-like proficiency. Generally empirical data from course books handbook articles and journal articles as well as commentaries by different authors are used in order to follow the research question up. First a framework concerning the origins of the idea of a sensitive period from first language acquisition and the clarification of particular terms will be created. Then the distinction between possible advantages of young learners in natural as well as instructional settings will be of interest.The findings on a critical or sensitive period have a
