Sizing up numbers: Exploring individuals’ numerical magnitude understanding of natural and rational numbers using eye tracking KU Leuven
It is a well-established finding that the numerical magnitude of natural numbers (e.g., 250) is better understood than that of rational numbers (e.g., ¼ or 0.25; Vamvakoussi, Christou, & Vosniadou, 2018). Consequently, number type (i.e., natural vs. rational) can be regarded as source of difficulty in numerical magnitude understanding. However, research has shown, within the class of rational numbers, that the numerical magnitude ...
