Abstract In 2011, Cohen and Blanc-Goldhammer introduced a new unbounded version of
the number line estimation task which they argued to overcome limitations of its …

Young children's estimates of numerical magnitude increase approximately logarithmically
with actual magnitude. The conventional interpretation of this finding is that children's …

Kim and Opfer (2017) found that number-line estimates increased approximately
logarithmically with number when an upper bound (eg, 100 or 1000) was explicitly marked …

Memory for numbers improves with age. One source of this improvement may be learning
linear spatial–numeric associations, but previous evidence for this hypothesis likely …

Despite the prevalence of quantity representation in everyday life, important questions
regarding the ability remain unanswered, including how quantity representation is structured …

Recently, a new unbounded version of the number line estimation task has been introduced
by Cohen and Blanc-Goldhammer (2011). The authors suggested the task to provide a purer …
