Acquisition processes in maximally diverse languages: min(d)ing the ambient language

Children can learn any language. This is astonishing given how different languages are. The main question driving the ACQDIV project [ˈækdɪv] is therefore: How is acquisition possible in spite of the great diversity found in the languages of the world?
Here is an example. The sentence 'Mummy, cook rice for me!' is expressed as follows in Chintang, a small Tibeto-Burman language which forms part of the ACQDIV corpus and which is spoken in the east of Nepal: Ama, kok thuktabidahã!

This simple sentence differs from the English version in many respects:

  • The noun ama does not only mean 'mother' but 'my mother' - it contains a prefix a- that indicates the possessor.
  • The object noun kok precedes the verb ("rice cook").
  • There is no word corresponding to me. Person and number of the beneficient as well as of the cook are coded in the verb (-ahã).
  • There is no word corresponding to for. This is also included in the verb form (-bid).

Nevertheless, children have no difficulties in learning this language or any other of the approximately 7000 languages spoken around the world. How is this possible?

In trying to answer this question, ACQDIV analyses data from ten languages taken from five maximally diverse language clusters. Taking less well-known languages into consideration is crucial for our enterprise: research on language acquisition is heavily biased towards comparatively big European languages, which are all very similar to each other, so data from these languages do not help much in answering the question how children deal with diversity.
