“…Indeed, a large number of studies have shown that numerical judgments are highly influenced by the visual perceptual properties of the stimulus (e.g. density, sum of perimeter, surface area, length, size…) in children and adults (Dormal & Pesenti, 2007;Gebuis, Cohen Kadosh, de Haan, & Henik, 2009;Rousselle & Noël, 2008;Rousselle, Palmers, & Noël, 2004). Some studies even fail to find any evidence of a sensitivity to numerical differences when the perceptual variables, which naturally covary with numerosities, are strictly controlled for (Clearfield & Mix, 1999, 2001Feigenson, Carey, & Spelke, 2002;Mix, 2002;Rousselle et al, 2004).…”

“…The stimuli were composed of a sound (audio format: 44100 Hz, 32 bits, Mono) presented rapidly. To prevent participants from basing their judgment on perceptual non-numerical dimensions, the sequences were constructed using non-periodic signals so that temporal ratios did not constitute a potentially confusing variable, and rhythm biases and pattern recognition were avoided (for more details, see Breukelaar & Dalrymple-Alford, 1998;Dormal et al, 2010;Dormal et al, 2006). The durations of the interstimuli interval (ISI) and of the sound presentation time (S) were added within each sequence to obtain the total cumulative duration.…”

“…A classical collection comparison was used to assess numerical magnitude processing but, as discussed earlier, this task placed strong emphasis on visuo-spatial processing since stimuli varied in terms of global surface, area and perimeter. Accordingly, a complementary method was used to assess numerical processing using two numerical comparison tasks with sequences of visual and auditory events (dots or sounds), as used in previous studies (Breukelaar & Dalrymple-Alford, 1998;Dormal, Andres, Dormal, & Pesenti, 2010;Dormal, Seron, & Pesenti, 2006). The dot sequence comparison task minimizes the visuo-spatial load since a single dot is repeatedly flashed at the centre of the screen (visual processing but low spatial demand).…”

Evidence of the impact of visuo-spatial processing on magnitude representation in 22q11.2 microdeletion syndrome

The influence of visuo-spatial skills on numerical magnitude processing is the subject of a long-standing debate. As most of the numerical and non-numerical magnitude abilities underpinning mathematical development are visual by nature, they are often assessed in the visual modality, thereby confusing visuo-spatial and numerical processing. In order to assess the influence of visuo-spatial processing on numerical magnitude representation, we examined magnitude processing in patients with 22q11.2 deletion syndrome (22q11DS), a genetic condition characterized by a cognitive profile with a relative weakness in visuo-spatial abilities but with preserved verbal abilities. Twenty-seven participants with 22q11DS were compared to two control groups (one matched on verbal intelligence and the other on visuospatial abilities) on several magnitude comparison tasks each with different visuo-spatial processing requirements. Our results showed that participants with 22q11DS present a consistent pattern of impairment in magnitude comparison tasks requiring the processing of visuo-spatial dimensions: comparison of lengths and collections. In contrast, their performance did not differ from the control groups in a visual task with no spatial processing requirement (i.e. numerical comparison of flashed dot sequences) or in auditory tasks (i.e., duration comparison and numerical comparison of sound sequences). Finally, a specific deficit of enumeration processes was observed in the subitizing range. Taken together, these results show that deficits in magnitude can occur as a consequence of a visuo-spatial deficit.

“…With respect to the hypothesis that time representations acquire a degree of abstraction only when they reach the global workspace, evidence is accumulating for shared neural substrates underlying the computations of time, space and numerosity as magnitudes (Walsh 2003;Bueti & Walsh 2009): repetitive transcranial magnetic stimulation (rTMS) over the parietal cortex, also implicated in the representation of numbers (Hubbard et al 2005), impairs temporal perception (Giacomo et al 2003;Walsh 2003;Alexander et al 2005;Battelli et al 2007;Koch et al 2009). Recent psychophysical data have demonstrated the automatic influence of size (Xuan et al 2007) and numerosity (Dormal et al 2006) on duration judgements; however, and importantly, duration does not impair numerosity (Dormal et al 2006). This asymmetry suggests that access to temporal representations is not automatic and need explicit attentional focus to be brought to awareness: in this process, numerosity can affect the extraction of temporal representations especially if using similar computational resources, for instance, in reaching the global workspace.…”

How long did it take you to read this sentence? Chances are your response is a ball park estimate and its value depends on how fast you have scanned the text, how prepared you have been for this question, perhaps your mood or how much attention you have paid to these words. Time perception is here addressed in three sections. The first section summarizes theoretical difficulties in time perception research, specifically those pertaining to the representation of time and temporal processing. The second section reviews non-exhaustively temporal effects in multisensory perception. Sensory modalities interact in temporal judgement tasks, suggesting that (i) at some level of sensory analysis, the temporal properties across senses can be integrated in building a time percept and (ii) the representational format across senses is compatible for establishing such a percept. In the last section, a two-step analysis of temporal properties is sketched out. In the first step, it is proposed that temporal properties are automatically encoded at early stages of sensory analysis, thus providing the raw material for the building of a time percept; in the second step, time representations become available to perception through attentional gating of the raw temporal representations and via re-encoding into abstract representations.

“…As a consequence of this law, the distance (i.e., the ability to discriminate two numbers increases as the numerical distance between them increases) and size (i.e., at equal numerical distance, the discrimination of two numbers decreases as their numerical size increases) effects typically encountered in numerical judgments (Buckley & Gillman, 1974;Moyer & Landauer, 1967;Restle, 1970; van Oeffelen & Vos, 1982), are also present in most judgments of quantifiable dimensions such as line lengths (e.g., Fias, Lammertyn, Reynvoet, Dupont, & Orban, 2003) and duration of sequences (e.g., Dormal, Seron, & Pesenti, 2006; DroitVolet, Tourret, & Wearden, 2004).…”

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...
