The present study aims to examine relations between number representations and various
sources of individual differences within early stages of development of number …

This experiment aimed to expand previous findings on the development of mental number
representation. We tested the hypothesis that children's familiarity with numbers is directly …

Recently, the nature of children's mental number line has received much investigation. In the
number line task, children are required to mark a presented number on a physical number …

The number‐line task has been extensively used to study the mental representation of
numbers in children. However, studies suggest that proportional reasoning provides a better …

Several studies investigating the development of approximate number representations used
the number-to-position task and reported evidence for a shift from a logarithmic to a linear …

Mental representations of numerical magnitude are commonly thought to undergo
discontinuous change over development in the form of a “representational shift.” This idea …

The performance in comparison and number line estimation is assumed to rely on the same
underlying representation, similar to a compressed mental number line that becomes more …

Number line estimation (ie, indicating the position of a given number on a physical line) is a
standard assessment of children's spatial representation of number magnitude. Importantly …

This study examined the generality of the logarithmic to linear transition in children's
representations of numerical magnitudes and the role of subjective categorization of …

In response to claims that the quality (and in particular linearity) of children's mental
representation of number acts as a constraint on number development, we carried out a …
