“…Participants had to detect an auditory lateralized target after the auditory presentation of a large (8 or 9) or a small (1 or 2) number. In the sighted group, the amplitude of the sensory N100 component was modulated by congruency (as previously demonstrated by Salillas, El Yagoubi, & Semenza, 2008): it demonstrated enhanced amplitude when auditory stimuli were presented in a congruent versus incongruent location. The modulation of the N100 component was interpreted as the consequence of a top-down mechanism: the number activated a position on the mental number line which in turn exerted spatial shift of attention over auditory space.…”

In the past few years, the role of both domain-specific and domain-general factors on numerical development and mathematics achievement has been debated. In this paper, we focus on the role of visuo-spatial processes. We will more particularly review the numerical abilities of populations presenting atypical visuo-spatial processes: individuals with blindness, hemineglect, children presenting low visuo-spatial abilities, non-verbal learning disorder or Williams syndrome. We will show that math abilities of each population are relatively unique and are not necessarily associated with generalized math impairment. We will show that a better understanding of the strengths and weaknesses of each population gives further insights into our conceptual understanding of the development of numerical cognition. We will finally demonstrate how the comparison across disorders can impact on practical rehabilitation and educational strategies.Keywords: number, space, blindness, hemineglect, NVLD, Williams syndrome Journal of Numerical Cognition, 2017, Vol. 3(2), 344-364, doi:10.5964/jnc.v3i2.44 Received: 2016-05-10.

Meck and Church (1983) were the first to speculate about a unique functional mechanism (the accumulator model) that supports numerosity and duration processing. This model was later extended by A Theory Of Magnitude (ATOM; Bueti & Walsh, 2009;Walsh, 2003) that conjectures the existence of a central magnitude system for the processing of numerosity, space and time. At the neurofunctional level, brain areas located along the right intraparietal sulcus (IPS) were accordingly shown to be involved in numerosity, length and duration discrimination (e.g., Bueti & Walsh, 2009;Cohen Kadosh et al., 2005;Dormal, Dormal, Joassin, & Pesenti, 2012;Dormal & Pesenti, 2009). At the behavioral level, several studies demonstrated similarities across different magnitude systems. Discriminating numerosities, surface areas and durations for example leads to similar patterns of performance in babies (Brannon, Lutz, & Cordes, 2006;de Hevia, Izard, Coubart, Spelke, & Streri, 2014;Lourenco & Longo, 2010;vanMarle & Wynn, 2006;Xu & Spelke, 2000; for a review, see Feigenson, 2007). And various similaritie...

“…There are several other interference studies relevant to the common cortical processing of magnitudes: number can influence attentional orientation (Fischer et al 2003;Salillas et al 2008); temporal judgements are susceptible to spatial-numerical association of response code (SNARC)-like effects, consistent with a generalized spatial quantity association of response code (SQUARC) effect predicted in Walsh (2003a,b), Ishihara et al (2008) and Muller & Schwarz (2008).…”

The development of sub-disciplines within cognitive neuroscience follows common sense categories such as language, audition, action, memory, emotion and perception among others. There are also well-established research programmes into temporal perception, spatial perception and mathematical cognition that also reflect the subjective impression of how experience is constructed. There is of course no reason why the brain should respect these common sense, text book divisions and, here, we discuss the contention that generalized magnitude processing is a more accurate conceptual description of how the brain deals with information about time, space, number and other dimensions. The roots of the case for linking magnitudes are based on the use to which magnitude information is put (action), the way in which we learn about magnitudes (ontogeny), shared properties and locations of magnitude processing neurons, the effects of brain lesions and behavioural interference studies. Here, we assess this idea in the context of a theory of magnitude, which proposed common processing mechanisms of time, space, number and other dimensions.

“…as either small or large, which in turn activates left or right responses" (p. 41; see also Gevers et al, 2010). Fischer, Castel, Dodd, and Pratt (2003) found a different type of interaction in a visual cued-detection task in which targets were detected faster if they were presented on the left and preceded by small rather than large numbers, or presented on the right and preceded by large rather than small numbers (see also Casarotti, Michielin, Zorzi, & Umiltà, 2007;Cattaneo, Silvanto, Battelli, & PascualLeone, 2009;Galfano, Rusconi, & Umiltà, 2006;Salillas, El Yagoubi, & Semenza, 2008). Although response selection was irrelevant, minor modifications of Gevers et al (2006b) model could account for these results, with an automatic categorization of the central number into small versus large, and a consequent activation of left versus right spatial codes.…”
