a

Reduced model included zero irregular past, auxiliary do omission, Wh- noninversion, overregularization (50% of variance explained).

b

Reduced model included zero irregular past, Wh- noninversion, zero irregular third (45% of variance explained).

c

Reduced model included zero irregular past, auxiliary do omission, zero irregular third, omission of infinitive to, subject-verb agreement with don’t (72% of variance explained).
