The Dual-Route Model of Order Judgment: Factors Influencing Task Performance and the Reverse Distance Effect
… numerical processing in number comparison and order judgment tasks. In number comparison tasks, people show a canonical distance effect (CDE): They are slower to compare numbers that are close together (e.g., 4-5) than those that are far apart (e.g., 4-9). However, when judging if sequences such …
