“…In the present study, numbers have been classified into two categories only -'simple' and 'complex' -on the basis of two complementary bodies of research: psycholinguistics (Rosch, 1975) and cognitive science (e.g. Dehaene & Mehler, 1992;Feigenson, Dehaene, & Spelke, 2004;Jansen & Pollmann, 2001;Pollmann & Jansen, 1996;Sigurd, 1988) on the one hand, and corpus-based analyses of number frequencies on the other hand (Coupland, 2011;Hofland & Johansson, 1982). Pioneering experimental work by Rosch (1975) showed that multiples of 10 are used by speakers as reference points in relation to which other numbers are judged, and that hedges such as almost, roughly, basically, serve to relate the latter to the former.…”
