Cumulative markedness effects and (non-)linearity in phonotactics

How do grammars assess the well-formedness of words with multiple phonotactic violations? Certain models predict that as strength restrictions decrease, forms violate should be less acceptable than expected, in a pattern we term super-linear cumulativity. We test this prediction using series Artificial Grammar Learning experiments, which vary number exceptions to patterns artificial languages. find cumulativity is indeed observed conditions weakest restrictions. Strikingly, participants exhibit even when trained language does not contain evidence for it.
