When communicating, bilinguals must successfully manage two conflicting languages; one must be accessed whilst the other is suppressed, in order to avoid involuntary language switching. The cognitive demands of this task are thought to be the origin of the bilingual advantage in executive control. A series of studies have demonstrated that bilinguals outperform their peers on tests of non-linguistic interference. Bilingual children, middle aged adults and older adults consistently record fa...

Consider first the nature of primary linguistic data. This consists of a finite amount of information about sentences, which, furthermore, must be rather restricted in scope, considering the time limitations that are in effect, and fairly degenerate in quality (cf. note 1 4). For example, certain signals might be accepted as properly formed sentences, while others are classed as nonsentences, as a result of correction of the learner's attempts on the part of the linguistic community.
