“…In N+ patients lesions superimposed in the right putamen and in the white matter underneath the insula, the rolandic operculum and the precentral gyrus (four patients); in NÀ patients a maximum puntiform overlap was observed in the white matter underneath the postcentral gyrus (three patients). As found in many previous studies (Cattaneo, Fantino, Mancini, Mattioli, & Vallar, 2012;Leibovitch et al, 1998) N+ patients had larger lesion volumes (mean 50.18 cc, SD ± 55.24, range 160.10-2.40), than NÀ patients (mean 5.05 cc, SD ± 6.25, range 17.30-2.10); t 7 = 2.29), although there was a great variability across both N+ and NÀ patients. Scan images of the ischemic lesion were not available for mapping for NÀ patients SG (white matter damage), and BA (parieto-frontal damage).…”

“…In this task, participants were asked to estimate the midpoint of visually or haptically explored rods while listening to a small digit ("2"), a large digit ("8"), or a non-numerical auditory stimulus ("blah"). While listening to the small digit shifted the perceived midline leftwards, listening to the large digit shifted the perceived midline rightwards.These shifts were moreover observed independently of the modality of response, both in healthy individuals and in patients presenting hemineglect (Cattaneo, Fantino, Mancini, Mattioli, & Vallar, 2012).Besides the observations made in bisection tasks, numerical distortions following hemineglect have also been found in symbolic and non-symbolic comparison tasks (Masson, Pesenti, & Dormal, 2013). Indeed, when asked to judge if an Arabic digit or a sequence of flashed dots was smaller or larger than a reference value (i.e., 5), patients with hemineglect presented impaired performances to smaller magnitudes and an enhanced distance effect for stimuli of smaller numerical magnitude than the reference.…”

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).

Line and word bisection in right-brain-damaged patients with left spatial neglect

et al. 2013

Right-brain-damaged patients with left unilateral spatial neglect typically set the mid-point of horizontal lines to the right of the objective center. By contrast, healthy participants exhibit a reversed bias (pseudoneglect). The same effect has been described also when bisecting orthographic strings. In particular, for this latter kind of stimulus, some recent studies have shown that visuo-perceptual characteristics, like stimulus length, may contribute to both the magnitude and the direction bias of the bisection performance (Arduino et al. in Neuropsychologia 48:2140-2146, 2010). Furthermore, word stress was shown to modulate reading performances in both healthy participants, and patients with left spatial neglect and neglect dyslexia (Cubelli and Beschin in Brain Lang 95:319-326, 2005; Rusconi et al. in Neuropsychology 18:135-140, 2004). In Experiment I, 22 right-brain-damaged patients (11 with left visuo-spatial neglect) and 11 matched neurologically unimpaired control participants were asked to set the subjective mid-point of word letter strings, and of lines of comparable length. Most patients exhibited an overall disproportionate rightward bias, sensitive to stimulus length, and similar for words and lines. Importantly, in individual patients, biases differed according to stimulus type (words vs. lines), indicating that at least partly different mechanisms may be involved. In Experiment II, the putative effects on the bisection bias of ortho-phonological information (i.e., word stress endings), arising from the non-neglected right hand side of the stimulus were investigated. The orthographic cue induced a rightward shift of the perceived mid-point in both patients and controls, with short words stressed on the antepenultimate final sequence inducing a smaller rightward deviation with respect to short words stressed on the penultimate final sequence. In conclusion, partly different mechanisms, including both visuo-spatial and lexical factors, may support line and word bisection performance of right-brain-damaged patients with left spatial neglect, and healthy participants.
