ABSTRACT
This chapter introduces the non-veridicality approach to polarity items first. We focus on the work of Cheng and Giannakidou (2005, 2013) which took Chinese polarity items as intensionalized and can only be licensed in non-veridical context. Several types of investigations have been done to prove that their non-veridical approach cannot explain Chinese polarity sensitivity very well. We show that the pre-dou position is the most crucial reason and then argue against the opinion that dou is a maximality operator. Then what is essential role of dou in licensing polarity items? We leave this question to the next chapter.
