What is a Weber Fraction?
Model Representations of the ANS
In modeling performance on tasks that engage the ANS, it is necessary first to specify a model for the underlying approximate number representations. It is generally agreed that each numerosity is mentally represented by a distribution of activation on an internal “number line.” These distributions are inherently “noisy” and do not represent number exactly or discretely . This means that there is some error each time they represent a number; and this error can be thought of as a spread of activation around the number being represented.
