ABSTRACT

In the area of numerical cognition many scholars believe in the existence of an innate number sense. This number sense is based on the ability to count and to estimate quantities. We examine a relatively neglected aspect of performance – the ability to perceive and evaluate sizes or amounts. We suggest that this might be a more primitive system that has been used throughout the years as the basis for the development of the number sense and numerical abilities. We present behavioral data regarding the ability to evaluate sizes in humans, some preliminary experiments in life forms with a low-level brain system (i.e., the Archer fish), and preliminary ideas with evolutionary computation.
