Abstract.Background: Poor numeracy and numerical learning problems are very common in our society and present serious obstacles in daily live, school or professional success. Accordingly, the goal of this study was ...
The present paper reviews some of the changes that the introduction of a new currency—the euro—will bring to our everyday behavior, from the point of view of the psychological literature on numerical cognition. Problems that can be foreseen converting and ...
Abstract. We investigate whether two-digit numbers are decomposed for purposes of numerical comparison (e.g., choosing the larger one). Earlier theorists concluded that numbers are processed holistically (Brysbaert, 1995; Dehaene, Dupoux, & Mehler, 1990), ...
Bimanual parity judgments of numerically small (large) digits are faster with the left (right) hand (the SNARC effect; Dehaene, Bossini, & Giraux, 1993). According to one explanation, this effect is culturally derived and reflects ontogenetic influences ...
Abstract. Evidence suggests that numbers are intimately related to space (Dehaene, Bossini, & Giraux, 1993; Hubbard, Piazza, Pinel, & Dehaene, 2005). Recently, Walsh (2003) suggested that numbers might also be closely related to time. To investigate this ...
Canonical finger numeral configurations are named faster than less familiar finger configurations and activate a semantic place-coding representation as symbolic stimuli. However, this does not exclude categorically the possibility that mere visuo-...
Previous studies have provided evidence of interference due to a language-default mode (i.e., the singular/plural opposition) in 2-year-old children when solving arithmetic problems using a traditional onlooker method. However, an action-based method ...
Developmental studies indicate that children initially possess a compressed intuition of numerical distances, in which larger numbers are less discriminable than small ones. Education then “linearizes” this responding until by about age eight, children ...
The present study examined the processing of unit fractions and the extent to which it is affected by context. Using a numerical comparison task we found evidence for a holistic representation of unit fractions when the immediate context of the fractions ...
A nascent idea in the numerical cognition literature – the analogical hypothesis (Pinel, Piazza, Bihan, & Dehaene, 2004) – assumes a common noisy code for the representation of symbolic (e.g., numerals) and nonsymbolic (e.g., numerosity, physical size, ...
Abstract. Past research has shown that performance in ordinal magnitude tasks is enhanced when stimuli are presented in ascending order, suggesting that magnitude is mapped to temporal order, with small magnitude associated with early and ...
Abstract. Previous studies have discussed the symmetry of bidirectional mapping between approximate number system (ANS) and symbolic number system (SNS). However, these studies neglected the essential significance ...
Previous data from two-digit number naming show that when target and prime numbers share one digit at different positions (e.g., target 28 and prime 86 or 72) an inhibition effect may be observed (Ratinckx, Brysbaert, & Fias, 2005). Such an effect has ...
