The goal of this paper is to argue that negative concord is the “default value” for the two types of neg-sensitivity by investigating how Japanese children acquire NCIs in their language. The rest of this paper is organized as follows. In section 2, we review several syntactic differences between NPIs and NCIs and a morphosyntactic analysis of those items proposed by Kuno (2007). It is pointed ...

The role of negative compressibility is considered in detail. Experimental observations of negative bulk modulus in prestrained foam are presented and interpreted. A constrained microscopic model which exhibits negative compressibility is proposed. Some other negative and counterintuitive properties of matter, like negative Poisson’s ratio, negative thermal expansion, negative specific heat, an...
