Projection Problem

Language acquisition can be described as solving the projection problem: determining the mapping from primary linguistic data to the acquired grammar (Baker, 1979; Peters, 1972).  When language learning is so construed, the poverty of the stimulus becomes a problem of underdetermination.  That is, the projection from data to grammar is not unique, but is instead one-to-many: one set of primary linguistic data is consistent with many potential grammars.
