What about? From The Linguistics Journal:
It has been suggested that a marked parameter in L1 might be reset to an unmarked value in L2. The principle underlying this notion is the Redundancy Reduction Principle (Seliger, 1996). The simple idea behind this theory is that “when two languages come into contact within the same psycholinguistic environment, the speaker is forced to solve the duplication of rules and functions in two languages and simplify the cognitive overload” (p. 616).
All the best.
