“…In line with previous research as described above, we expected basic numerical abilities to predict time reading in general significantly. In particular, addition (reflecting magnitude manipulation) and arithmetic fact knowledge (e.g., multiplication) were shown to be significant predictors of mathematical achievement in general (e.g., Geary, Nicholas, Li, & Sun, 2017;Jordan, Hanich, & Kaplan, 2003;Krajewski & Schneider, 2009;Träff, Skagerlund, Olsson, & Östergren, 2017) and digital time reading but also to a lesser extent analog time reading in particular (e.g., Friedman & Laycock, 1989). Even tough studies are missing, it seems reasonable that subtraction skills also reflecting magnitude manipulation (e.g., Dehaene & Cohen, 1997) should also be a relevant predictor of time reading in general.…”
