From “sense of number” to “sense of magnitude”: The role of continuous magnitudes in numerical cognition

In this review, we are pitting two theories against each other: the more accepted theory, the number sense theory , suggesting that a sense of number is innate and non-symbolic numerosity is being processed independently of continuous magnitudes (e.g., size, area, and density); and the newly emerging theory suggesting that (1) both numerosities and continuous magnitudes are processed holistically when comparing numerosities and (2) a sense of...
