“…Evidence for the componential processing of multi-digit numbers complying with the place-value structure of the Arabic number system comes from a broad variety of tasks ranging from simple magnitude comparison to more complex numerical and arithmetical tasks. For instance, the unit-decade compatibility effect is one indicator of the componential processing of tens and units in number magnitude comparison (Nuerk, Weger, & Willmes, 2001): number pairs for which separate comparisons of tens and units yield compatible decision biases (e.g., 42_57; 4 < 5 and 2 < 7) are responded to faster and with fewer errors than number pairs for which these separate comparisons of tens and units yield incompatible decision biases (e.g., 47_62, 4 < 6, but 7 > 2, e.g., Ganor-Stern, Tzelgov, & Ellenbogen, 2007;Kallai & Tzelgov, 2012;Macizo & Herrera, 2013;Moeller, Klein, Nuerk, & Willmes, 2013; see also Bahnmueller, Moeller, Mann, & Nuerk, 2015, Korvorst & Damian, 2008, for evidence on three-digit numbers).…”
