Some linguists have provided evidence which may be taken to support Kayne's scheme, such as Lin, who considered Standard Chinese sentences with the sentence-final particle "le". Certain restrictions on movement from within verb phrases preceding such a particle are found (if various other assumptions from the literature are accepted) to be consistent with the idea that the verb phrase has moved from its underlying position after its head (the particle "le" here being taken as the head of an aspect phrase). However, Takita (2009) observes that similar restrictions do not apply in Japanese, in spite of its surface head-final character, concluding that if Lin's assumptions are correct, then Japanese must be considered to be a true head-final language, contrary to the main tenet of Antisymmetry. More details about these arguments can be found in the Antisymmetry article.
