A thorough investigation of different ANS measures and executive functions in mathematics achievement in children. Journal of cognitive psychology, https://doi.org/10.1080/20445911.2022.2044338

The ability to represent approximate numerical magnitudes is often referred to as the approximate number system (ANS) and has regularly been proposed as foundational to mathematics achievement. However, some argue that the relation between ANS acuity... Read More about The approximate number system and mathematics achievement: it's complicated.

Superior numerical abilities following early visual deprivation (2013)
Journal Article

In numerical cognition vision has been assumed to play a predominant role in the elaboration of the numerical representations and skills. However, this view has been recently challenged by the discovery that people with early visual deprivation not o... Read More about Superior numerical abilities following early visual deprivation.

Impact of high mathematics education on the number sense. (2012)
Journal Article
Castronovo, J., & Göbel, S. M. (2012). Impact of high mathematics education on the number sense. PLoS ONE, 7(4), e33832. https://doi.org/10.1371/journal.pone.0033832

In adult number processing two mechanisms are commonly used: approximate estimation of quantity and exact calculation. While the former relies on the approximate number sense (ANS) which we share with animals and preverbal infants, the latter has bee...

Numerical comparison of two-digit numbers: How differences at encoding can involve differences in processing (2011)
Journal Article
Castronovo, J., & Crollen, V. (2011). Numerical comparison of two-digit numbers: How differences at encoding can involve differences in processing. Journal of cognitive psychology, 23(1), 8-17. https://doi.org/10.1080/20445911.2011.445985

The study of two-digit numbers processing has recently gathered a growing interest. Here, we examine whether differences at encoding of two-digit oral verbal numerals induce differences in the type of processing involved. Twenty-four participants wer...

Bilateral field advantage in visual enumeration (2011)
Journal Article
Delvenne, J., Castronovo, J., Demeyere, N., & Humphreys, G. W. (2011). Bilateral field advantage in visual enumeration. PLoS ONE, 6(3), https://doi.org/10.1371/journal.pone.0017743

A number of recent studies have demonstrated superior visual processing when the information is distributed across the left and right visual fields than if the information is presented in a single hemifield (the bilateral field advantage). This effec... Read More about Bilateral field advantage in visual enumeration.

An electrophysiological measure of visual short-term memory capacity within and across hemifields (2011)
Journal Article

Recent electrophysiological research has identified a specific contralateral correlate of the contents of visual short-term memory (VSTM). This posterior contralateral delay activity (CDA) persists during the retention period, and its amplitude is mo...

Over the last 30 years, numerical estimation has been largely studied. Recently, Castronovo and Seron (2007) proposed the bidirectional mapping hypothesis in order to account for the finding that dependent on the type of estimation task (perception v...

Vision was for a long time considered as essential in the elaboration of the semantic numerical representation (e.g., Simon, 1999). However, early visual deprivation does not prevent the elaboration of a numerical representation with similar spatial...
