Abstract Representations of the fingers are embodied in our cognition and influence
performance in enumeration tasks. Among deaf signers, the fingers also serve as a tool for …

Most developers and publishers claim that their curricula or approach to teaching are based
on research, but few explicate their claims. In this chapter, we briefly assess the state of …

Developmental dyscalculia (DD) is a learning disability that is characterized by severe
difficulties with acquiring age-appropriate mathematical skills that cannot be attributed to …

Visual number comparison does not require participants to choose a unit, whereas units are
fundamental to the definition of number. Studies using magnitude estimation rather than …

Leibovich et al. argue that it is impossible to control for all continuous magnitudes in a
numerical task. We contend that continuous magnitudes (ie, perimeter, area, density) can be …

Leibovich et al. do not present enough empirical support to overturn decades of work
supporting a number sense nor to convince the reader that a magnitude sense provides a …

This book is the fruit of the collaboration of two experts interested in the problem of learning
disabilities in mathematics and dyscalculia: a child neuropsychologist and a mathematician …

We report novel findings from experiments on the enumeration of canonical patterns under
attentional load. While previous studies have shown that the process of enumerating …

Leibovich et al. propose that continuous magnitudes and a number sense are used
holistically to judge numerosity. We point out that their proposal is incomplete and …
