However, most of the errors our L2 Chinese learners make with Statives and  Activities are just the opposite: using the perfective marker -le when it is not needed.
the problem predicted by Claim 1 is UNDER-USE of the perfective marking on Statives and Activities and the L2 learners of Chinese display no UNDER-USE of the perfective marking on these situation types due to the fact that -le is usually NOT required on situations without boundaries.
