depends on a verbal count routine (eg,“one, two, three...”). However, these findings are …

Language for number is an important case study of the relationship between language and
cognition because the mechanisms of non-verbal numerical cognition are well-understood …

In numerical cognition research, it has traditionally been argued that the processing of
symbolic numerals (eg, digits) is identical to the processing of the non-symbolic …

The approximate number system (a) views number as an imprecise signal that (b) functions
equivalently regardless of a number's initial presentation. These features do not readily …

Does speaking a language without number words change the way speakers of that
language perceive exact quantities? The Pirahã are an Amazonian tribe who have been …

Abstract The Piraha, an Amazonian hunter-gatherer tribe, lack words for numbers and are
