Opfer, John; Kim, Dan; Young, Christopher J.; Marciani, Francesca – Grantee Submission, 2019
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 confounded memory span with quality of numerical magnitude representations and failed to distinguish spatial-numeric mappings from other numeric abilities, such as counting or…

Matthews, Percival G.; Lewis, Mark R. – Cognitive Science, 2017
Although many researchers theorize that primitive numerosity processing abilities may lay the foundation for whole number concepts, other classes of numbers, like fractions, are sometimes assumed to be inaccessible to primitive architectures. This research presents evidence that the automatic processing of nonsymbolic magnitudes affects processing…

Sella, Francesco; Sader, Elie; Lolliot, Simon; Cohen Kadosh, Roi – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2016
Recent studies have highlighted the potential role of basic numerical processing in the acquisition of numerical and mathematical competences. However, it is debated whether high-level numerical skills and mathematics depends specifically on basic numerical representations. In this study mathematicians and nonmathematicians performed a basic…

Forrest, Charlotte L. D.; Monsell, Stephen; McLaren, Ian P. L. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2014
Task-cuing experiments are usually intended to explore control of task set. But when small stimulus sets are used, they plausibly afford learning of the response associated with a combination of cue and stimulus, without reference to tasks. In 3 experiments we presented the typical trials of a task-cuing experiment: a cue (colored shape) followed,…

Skagerlund, Kenny; Träff, Ulf – Journal of Learning Disabilities, 2016
This study investigated if developmental dyscalculia (DD) in children with different profiles of mathematical deficits has the same or different cognitive origins. The defective approximate number system hypothesis and the access deficit hypothesis were tested using two different groups of children with DD (11-13 years old): a group with…

Hernandez, Mireia; Costa, Albert; Fuentes, Luis J.; Vivas, Ana B.; Sebastian-Galles, Nuria – Bilingualism: Language and Cognition, 2010
The main objective of this article is to provide new evidence regarding the impact of bilingualism on the attentional system. We approach this goal by assessing the effects of bilingualism on the executive and orienting networks of attention. In Experiment 1, we compared young bilingual and monolingual adults in a numerical version of the Stroop…

Weiss, Peter H.; Kalckert, Andreas; Fink, Gereon R. – Journal of Cognitive Neuroscience, 2009
In synesthesia, stimulation of one sensory modality leads to a percept in another nonstimulated modality, for example, graphemes trigger an additional color percept in grapheme-color synesthesia, which encompasses the variants letter-color and digit-color synesthesia. Until recently, it was assumed that synesthesia occurs strictly unidirectional:…

Sagiv, Noam; Simner, Julia; Collins, James; Butterworth, Brian; Ward, Jamie – Cognition, 2006
This study compares the tendency for numerals to elicit spontaneous perceptions of colour or taste (synaesthesia) with the tendency to visualise numbers as occupying particular visuo-spatial configurations (number forms). The prevalence of number forms was found to be significantly higher in synaesthetes experiencing colour compared both to…
