Superior numerical abilities following early visual deprivation (2013)
Journal Article
Castronovo, J., & Delvenne, J. F. (2013). Superior numerical abilities following early visual deprivation. Cortex; a journal devoted to the study of the nervous system and behavior, 49(5), 1435-1440. doi:10.1016/j.cortex.2012.12.018

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

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. doi: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... Read More

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

Bilateral field advantage in visual enumeration (2011)
Journal Article
Castronovo, J., Delvenne, J., Demeyere, N., & Humphreys, G. W. (2011). Bilateral field advantage in visual enumeration. PloS one, 6(3), doi:10.1371/journal.pone.0017743. ISSN 1932-6203

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

An electrophysiological measure of visual short-term memory capacity within and across hemifields (2011)
Journal Article
Delvenne, J. F., Kaddour, L. A., & Castronovo, J. (2011). An electrophysiological measure of visual short-term memory capacity within and across hemifields. Psychophysiology, 48(3), (333-336). doi:10.1111/j.1469-8986.2010.01079.x. ISSN 0048-5772

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... Read More

Under- and Over-Estimation: A Bi-Directional Mapping Process Between Symbolic and Non-Symbolic Representations of Number? (2011)
Journal Article
Crollen, V., Seron, X., & Castronovo, J. (2011). Under- and Over-Estimation: A Bi-Directional Mapping Process Between Symbolic and Non-Symbolic Representations of Number?. Experimental Psychology, 58(1), 39-49. doi:10.1027/1618-3169/a000064

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... Read More

Subitizing in congenitally blind adults (2010)
Journal Article
Castronovo, J., Riggs, K. J., & Ferrand, L. (2010). Subitizing in congenitally blind adults. Psychonomic bulletin & review, 17(6), (840-845). doi:10.3758/PBR.17.6.840. ISSN 1069-9384

We investigated the role of vision in tactile enumeration within and outside the subitizing range. Congenitally blind and sighted (blindfolded) participants were asked to enumerate quickly and accurately the number of fingers stimulated. Both groups... Read More

Numerical estimation in blind subjects: evidence of the impact of blindness and its following experience (2007)
Journal Article

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... Read More

Semantic numerical representation in blind subjects: The role of vision in the spatial format of the mental number line (2007)
Journal Article
Castronovo, J., & Seron, X. (2006). Semantic numerical representation in blind subjects: The role of vision in the spatial format of the mental number line. Quarterly Journal of Experimental Psychology, 60(1), (101-119). doi:10.1080/17470210600598635. ISSN 1747-0218

Does vision play a role in the elaboration of the semantic representation of small and large numerosities, notably in its spatial format? To investigate this issue, we decided to compare in the auditory modality the performance of congenitally and ea... Read More
