A new megastudy has been published with lexical decision times to 2500 single character Chinese (Mandarin) words (Sze, Liow, & Yap, 2013). When the correlations with the various frequency measures were correlated, SUBTLEX-CH came out as the best. Further noteworthy was that the still frequently used Chinese word frequency measure based on the Dictionary of Modern Chinese frequency (1986) was by far the worst.
