DIE STADIEN IM ERWERB DES MORPHOSYNTAKTISCHEN REGELSYSTEMS IN DER ERSTSPRACHE

In the process of first language acquisition children select the data from the environment. Important principles are those of pattern selection (the child selects some forms in some contexts due to token frequency and saliency) and of self-organization (the child does not merely imitate input elements but constructs their patterns in reaction to the intake). This paper shows the development of the first language morphosyntactic system; focus will be laid on the constructive character of language acquisition.
