Positron emission tomography was used to localize the cerebral networks specifically involved
in three basic numerical processes: arabic numeral processing, numerical magnitude …

Calculating prodigies are individuals who are exceptional at quickly and accurately solving
complex mental calculations. With positron emission tomography (PET), we investigated the …

Some authors proposed that exact mental calculation is based on linguistic representations
and relies on the perisylvian language cortices, while the understanding of proximity …

The existence of a possible common mechanism for duration and numerosity processing was
tested with a Stroop task. Participants had to compare either the duration or the numerosity …

Some people declare that they possess a personal visual representation of numbers: some
automatically “see” the numbers they are confronted with in a precise location in a structured …

Finger–digit response compatibility was tested by asking participants to identify Arabic digits
by pressing 1 of 10 keys with all 10 fingers. The direction of the finger–digit mapping was …

Discrete numerosities can be represented by various finger configurations. The impact of
counting strategies on these configurations and their possible semantic status were …

Behavioural, neuropsychological and functional imaging studies suggest possible interactions
between number processing and finger representation. Since grasping requires the …

The history of mathematics provides several examples of the use of fingers to count or
calculate. These observations converge with developmental data showing that fingers play a …

Rips et al. claim that the principles underlying the structure of natural numbers cannot be
inferred from interactions with the physical world. However, in their target article they failed to …
